The Custom Connector Lie: How to Really Add MCP to Copilot Studio

1
00:00:00,000 --> 00:00:04,940
You've been told that adding the model context protocol MCP for short to co-pilot studio is easy.

2
00:00:04,940 --> 00:00:06,880
Just use a custom connector, they say.

3
00:00:06,880 --> 00:00:09,040
Technically, that's true. Functionally, it's a lie.

4
00:00:09,040 --> 00:00:11,920
The same kind of lie as just plug in the USB.

5
00:00:11,920 --> 00:00:15,880
Without telling you which side is up or that you need a driver, three registry edits,

6
00:00:15,880 --> 00:00:19,380
and a mild prayer to the cloud gods for packet stability.

7
00:00:19,380 --> 00:00:22,440
MCP is marketed as USB for AI agents.

8
00:00:22,440 --> 00:00:23,840
The idea sounds clean.

9
00:00:23,840 --> 00:00:28,200
Any agent can talk to any knowledge source if they both follow the same protocol,

10
00:00:28,200 --> 00:00:33,680
a universal handshake for context, but Microsoft, ever the minimalist, hands you only the port.

11
00:00:33,680 --> 00:00:36,480
No cable, no pinot diagram, not even a warning label.

12
00:00:36,480 --> 00:00:40,200
So yes, you can connect something, but half the time it's just ornamental.

13
00:00:40,200 --> 00:00:42,800
The myth persists because the interface looks obedient.

14
00:00:42,800 --> 00:00:46,000
Add a tool it cools, filter by model context protocol.

15
00:00:46,000 --> 00:00:48,760
You click, a drop down appears, and voila.

16
00:00:48,760 --> 00:00:50,280
Instant interoperability.

17
00:00:50,280 --> 00:00:53,760
Except not, what you're really connecting to are built in MCPs,

18
00:00:53,760 --> 00:00:55,720
once wired directly into the product.

19
00:00:55,720 --> 00:00:58,760
Dataverse MCP, that works because it's Microsoft's own.

20
00:00:58,760 --> 00:01:02,560
Your custom MCP, co-pilot doesn't even recognize it until you build a translator,

21
00:01:02,560 --> 00:01:06,360
a custom connector that behaves not like a shortcut, but like a full diplomatic mission

22
00:01:06,360 --> 00:01:09,240
between systems that don't share vocabulary or tempo.

23
00:01:09,240 --> 00:01:10,960
So today we're going to dismantle the myth.

24
00:01:10,960 --> 00:01:15,520
I'll show you what MCP actually is, why your connector isn't as plugged in as it pretends,

25
00:01:15,520 --> 00:01:19,440
and how to build one that genuinely exchanges context instead of miming connectivity.

26
00:01:19,440 --> 00:01:23,440
MCP isn't a data source, it's a contextual bridge, the interpreter between your co-pilot

27
00:01:23,440 --> 00:01:25,440
and your external intelligence.

28
00:01:25,440 --> 00:01:29,160
Your custom connectors aren't add-ons, they're construction scaffolds for that bridge.

29
00:01:29,160 --> 00:01:33,120
So let's strip away Microsoft's marketing lacquer and peer into what really happens inside

30
00:01:33,120 --> 00:01:36,080
co-pilot studio when you think you've connected an MCP.

31
00:01:36,080 --> 00:01:37,440
The illusion of simplicity.

32
00:01:37,440 --> 00:01:42,520
At first glance, co-pilot studio makes MCP integration look as casual as adding milk to coffee, click

33
00:01:42,520 --> 00:01:47,600
add tool, filter by model context protocol, pick your server, done.

34
00:01:47,600 --> 00:01:49,360
A few seconds later, there it is.

35
00:01:49,360 --> 00:01:51,480
Listed proudly under tools.

36
00:01:51,480 --> 00:01:55,720
List users stop there and post in forums bragging that their external context is live.

37
00:01:55,720 --> 00:01:58,080
It isn't what you've connected is a placebo.

38
00:01:58,080 --> 00:01:59,080
Here's why.

39
00:01:59,080 --> 00:02:03,080
That friendly MCP filter only shows Microsoft's own built-ins.

40
00:02:03,080 --> 00:02:06,800
Dataverse MCP, SharePoint MCP, maybe one for GitHub if you're lucky.

41
00:02:06,800 --> 00:02:09,280
They live deep inside the same tenant infrastructure.

42
00:02:09,280 --> 00:02:13,800
The moment you try to link an external MCP, say Microsoft Learn or your in-house semantic

43
00:02:13,800 --> 00:02:15,480
search, you discover an empty shelf.

44
00:02:15,480 --> 00:02:18,720
There's no import slot, no authentication prompt, no actual handshake.

45
00:02:18,720 --> 00:02:23,880
The supposed protocol option is really just a category label on pre-installed toys.

46
00:02:23,880 --> 00:02:27,320
Under the hood, co-pilot expects a very specific formatting discipline.

47
00:02:27,320 --> 00:02:32,480
It wants a streamable HTTP endpoint that conforms to the MCP schema.

48
00:02:32,480 --> 00:02:37,320
Request shaped as contextual JSON, responses emitted as events, all time to stream tokens

49
00:02:37,320 --> 00:02:38,440
not dump them.

50
00:02:38,440 --> 00:02:41,760
Your external service, no matter how intelligent, is invisible unless it responds in that

51
00:02:41,760 --> 00:02:42,760
dialect.

52
00:02:42,760 --> 00:02:46,840
Without it, co-pilot acts like a tourist who memorized three travel phrases and insists

53
00:02:46,840 --> 00:02:48,600
the locals aren't speaking properly.

54
00:02:48,600 --> 00:02:52,800
This is the core lie, what looks like plug and play is actually code and pray.

55
00:02:52,800 --> 00:02:56,240
The visible UI hides the schema enforcement that makes MCP tick.

56
00:02:56,240 --> 00:03:00,360
When you select an MCP from the menu, you're not embedding your own model context.

57
00:03:00,360 --> 00:03:02,600
You're summoning an internal retrieval mechanism.

58
00:03:02,600 --> 00:03:07,160
It works ingeniously well with Bing style indexes and Dataverse APIs, but it never consults

59
00:03:07,160 --> 00:03:10,720
your MCP endpoint unless you manually craft the bridge.

60
00:03:10,720 --> 00:03:11,880
And here lies the paradox.

61
00:03:11,880 --> 00:03:15,880
Co-pilot studio is simultaneously one of the most powerful orchestration tools Microsoft

62
00:03:15,880 --> 00:03:19,240
has ever built and one of the most deceptively constrained.

63
00:03:19,240 --> 00:03:23,120
It promises universal context exchange but delivers selective amnesia unless you teach

64
00:03:23,120 --> 00:03:25,240
it new manners through configuration.

65
00:03:25,240 --> 00:03:28,200
Most admins discovering this for the first time assume a bug.

66
00:03:28,200 --> 00:03:32,400
This where they followed the documentation, imported the URL, hit refresh three times,

67
00:03:32,400 --> 00:03:33,400
still nothing appears.

68
00:03:33,400 --> 00:03:35,560
That's because they haven't built the bridge.

69
00:03:35,560 --> 00:03:37,840
They've merely painted a tunnel on the wall.

70
00:03:37,840 --> 00:03:40,360
Recognizing that illusion is the first step toward competence.

71
00:03:40,360 --> 00:03:42,600
Your connector panel isn't lying maliciously.

72
00:03:42,600 --> 00:03:46,680
Simply narrating the simplified version of reality meant for average users.

73
00:03:46,680 --> 00:03:47,680
But you're not average.

74
00:03:47,680 --> 00:03:49,960
You're the one expected to make it actually work.

75
00:03:49,960 --> 00:03:54,040
And that's the first step to enlightenment knowing that delightful little panel in Co-pilot

76
00:03:54,040 --> 00:03:55,720
studio is lying to you.

77
00:03:55,720 --> 00:03:57,280
What MCP actually is.

78
00:03:57,280 --> 00:03:59,360
Okay, let's define the creature we're dealing with.

79
00:03:59,360 --> 00:04:03,960
MCP, the model context protocol, isn't some file format or an API wrapper.

80
00:04:03,960 --> 00:04:07,880
It's a lingua franca for artificial intelligence systems away for distinct brains to share

81
00:04:07,880 --> 00:04:09,920
not data but meaning about data.

82
00:04:09,920 --> 00:04:12,440
Microsoft calls it USB for agents.

83
00:04:12,440 --> 00:04:16,080
It's not because it transmits bytes but because it standardizes the handshake, who plugs

84
00:04:16,080 --> 00:04:20,360
where, what current flows and how both sides agree that what's moving is valid context,

85
00:04:20,360 --> 00:04:21,360
not noise.

86
00:04:21,360 --> 00:04:26,280
Technically, MCP defines how an agent and a context source exchange structured metadata.

87
00:04:26,280 --> 00:04:29,680
Tool schemers, actions, parameters and tokens of context.

88
00:04:29,680 --> 00:04:31,520
Think of it as international diplomacy.

89
00:04:31,520 --> 00:04:36,280
The MCP server represents a sovereign nation of information, a set of rules about how a

90
00:04:36,280 --> 00:04:39,880
particular body of knowledge can be queried, summarized or updated.

91
00:04:39,880 --> 00:04:44,240
The MCP client, in this case, Co-pilot studio is the visiting envoy speaking on behalf

92
00:04:44,240 --> 00:04:45,560
of the user.

93
00:04:45,560 --> 00:04:47,440
And bridging the tool is the connector.

94
00:04:47,440 --> 00:04:52,280
Our very patient translator making sure query share point in one language becomes post V1

95
00:04:52,280 --> 00:04:54,200
context request in another.

96
00:04:54,200 --> 00:04:59,680
Inside the protocol, everything is JSON, predictably, efficiently, sometimes tediously JSON, so

97
00:04:59,680 --> 00:05:03,200
that even a large language model can pass it without daydreaming.

98
00:05:03,200 --> 00:05:05,000
Each request holds intent.

99
00:05:05,000 --> 00:05:08,320
Each response carries context tokens and optional citations.

100
00:05:08,320 --> 00:05:10,440
More interestingly, those responses are streamable.

101
00:05:10,440 --> 00:05:14,760
Co-pilot receives partial fragments while the MCP server assembles meaning that prevents

102
00:05:14,760 --> 00:05:17,880
the AI from freezing mid-thought and waiting for the full response.

103
00:05:17,880 --> 00:05:19,840
It's a relay race, not a package delivery.

104
00:05:19,840 --> 00:05:23,920
Now, Microsoft's USB metaphor seduces because it hints at simplicity.

105
00:05:23,920 --> 00:05:27,280
Plug A into B and electrons of knowledge begin to flow.

106
00:05:27,280 --> 00:05:29,240
But that analogy breaks down almost immediately.

107
00:05:29,240 --> 00:05:34,200
A physical USB cable assumes fixed pins, stable voltages and one kind of electricity.

108
00:05:34,200 --> 00:05:36,920
MCP by contrast negotiates dynamic schemers.

109
00:05:36,920 --> 00:05:42,360
Every device, each server implementation can define its own verbs, properties and contextual

110
00:05:42,360 --> 00:05:43,360
affordances.

111
00:05:43,360 --> 00:05:46,840
Imagine a USB drive that changes its wiring depending on whom it's plugged into.

112
00:05:46,840 --> 00:05:48,160
That's closer to reality.

113
00:05:48,160 --> 00:05:49,720
So what exactly lives where?

114
00:05:49,720 --> 00:05:53,760
At the base layer, the MCP server contains tool definitions, descriptions of actions like

115
00:05:53,760 --> 00:05:58,960
search docs, create record or list tables, along with required parameters and data types.

116
00:05:58,960 --> 00:06:00,240
It's the intelligence cortex.

117
00:06:00,240 --> 00:06:04,360
The MCP client, co-pilot studio, hosts the agent brain that interprets natural language

118
00:06:04,360 --> 00:06:06,680
prompts and decides which actions to invoke.

119
00:06:06,680 --> 00:06:09,600
And then the custom connector implements the contract.

120
00:06:09,600 --> 00:06:14,400
Handle authentication, validate schema and stream the conversation over HTTP while preserving

121
00:06:14,400 --> 00:06:15,720
structure.

122
00:06:15,720 --> 00:06:20,680
When co-pilot sends a prompt, say, find articles about SharePoint indexing, it isn't scraping

123
00:06:20,680 --> 00:06:21,680
web pages.

124
00:06:21,680 --> 00:06:25,720
It generates a contextual query embedded in JSON, pushes it through the connector to the

125
00:06:25,720 --> 00:06:30,320
MCP server and receives a structured contextual payload back, not raw text.

126
00:06:30,320 --> 00:06:35,600
That payload contains metadata, sources, relevant scores, snippet text, that the large

127
00:06:35,600 --> 00:06:38,600
language model then condenses into fluent English for the user.

128
00:06:38,600 --> 00:06:40,920
Its context synthesis, not simple retrieval.

129
00:06:40,920 --> 00:06:44,320
Without that discipline, co-pilot operates like a parrot repeating summaries of whatever

130
00:06:44,320 --> 00:06:45,560
being fed it.

131
00:06:45,560 --> 00:06:49,480
At MCP, and suddenly it remembers relationships, which document references, which API,

132
00:06:49,480 --> 00:06:53,600
which field in dataverse maps to which property in your CRM, which licensing clause governs

133
00:06:53,600 --> 00:06:54,600
that action.

134
00:06:54,600 --> 00:06:58,720
In essence, MCP upgrades co-pilot from auto completion with swagger to a semi-reliable

135
00:06:58,720 --> 00:07:02,640
analyst that actually understands the topology of your organization's data.

136
00:07:02,640 --> 00:07:07,400
So yes, USB for agents sounds catchy, but the practical interpretation is that MCP enforces

137
00:07:07,400 --> 00:07:10,120
polite conversation between very opinionated systems.

138
00:07:10,120 --> 00:07:13,760
It tells co-pilot studio to ask, "May I query this schema?"

139
00:07:13,760 --> 00:07:15,960
Instead of blurting, give me everything.

140
00:07:15,960 --> 00:07:20,080
That small courtesy is the difference between a hallucination and a compliant response.

141
00:07:20,080 --> 00:07:21,920
And here's the twist, Microsoft never highlights.

142
00:07:21,920 --> 00:07:26,080
The MCP drop down in co-pilot studio already speaks this protocol, but only with its own

143
00:07:26,080 --> 00:07:27,080
service.

144
00:07:27,080 --> 00:07:30,400
When you build a custom one, you're effectively authoring a new dialect within that

145
00:07:30,400 --> 00:07:31,400
treaty.

146
00:07:31,400 --> 00:07:34,960
And then you're defining what context actually means inside your enterprise walls.

147
00:07:34,960 --> 00:07:39,400
Knowing what MCP is, a dynamic structured grammar for context, not a data source, gives

148
00:07:39,400 --> 00:07:43,040
you the theory you need before committing the crime of implementation.

149
00:07:43,040 --> 00:07:44,480
Because next we'll commit it together.

150
00:07:44,480 --> 00:07:47,840
We'll build the handshake ourselves and prove that the real power in co-pilot studio doesn't

151
00:07:47,840 --> 00:07:49,000
come from the menu.

152
00:07:49,000 --> 00:07:50,920
It comes from understanding the contract.

153
00:07:50,920 --> 00:07:52,760
That's our practical heresy.

154
00:07:52,760 --> 00:07:57,280
Constructing your own, fully compliant, streamable custom connector that speaks fluent MCP

155
00:07:57,280 --> 00:07:59,120
instead of miming the accent.

156
00:07:59,120 --> 00:08:00,840
Building a real custom connector.

157
00:08:00,840 --> 00:08:03,400
Now we enter the part everyone rushes through.

158
00:08:03,400 --> 00:08:05,040
The actual construction.

159
00:08:05,040 --> 00:08:08,840
Most tutorials wave their hands vaguely and say, "Just import from GitHub."

160
00:08:08,840 --> 00:08:12,840
They omit the mind field of schema mismatches, host misconfigurations and authentication

161
00:08:12,840 --> 00:08:15,320
quirks waiting beneath that innocent looking button.

162
00:08:15,320 --> 00:08:18,960
Today we're walking through it pedantically because precision is the difference between an

163
00:08:18,960 --> 00:08:22,240
agent that thinks and one that sulk in silence.

164
00:08:22,240 --> 00:08:24,560
First understand the workflows skeleton.

165
00:08:24,560 --> 00:08:29,280
GitHub import, endpoint configuration, connector publishing, three bones, mis one joint and

166
00:08:29,280 --> 00:08:31,200
you have a lifeless limb.

167
00:08:31,200 --> 00:08:34,080
So let's start where Microsoft hides the bones in Power Apps make.

168
00:08:34,080 --> 00:08:37,800
That's where custom connectors are born, not in co-pilot studio itself.

169
00:08:37,800 --> 00:08:41,320
Co-pilot is merely the end consumer of whatever articulation you create here.

170
00:08:41,320 --> 00:08:44,280
When you click new custom connector, you're presented with options straight from the

171
00:08:44,280 --> 00:08:49,600
magician's head, from open API, from postman, from scratch, or blessed, import from GitHub.

172
00:08:49,600 --> 00:08:54,680
Choose that final one because Microsoft quietly maintains a repository of MCP connector templates

173
00:08:54,680 --> 00:08:55,920
in its developer branch.

174
00:08:55,920 --> 00:08:58,960
The template you actually need is labeled MCP streamable.

175
00:08:58,960 --> 00:09:03,640
Anything non-streamable will appear functional right up until the instant co-pilot asks the

176
00:09:03,640 --> 00:09:06,480
first question where upon it will fail silently.

177
00:09:06,480 --> 00:09:10,520
No fireworks, no errors, just a polite nothing.

178
00:09:10,520 --> 00:09:14,280
After choosing MCP streamable, point to the dev branch and click continue.

179
00:09:14,280 --> 00:09:18,120
The system fetches a blob of JSON defining the connector's parameters.

180
00:09:18,120 --> 00:09:23,920
Authentication, usually no authentication because MCP currently relies on tenant isolation.

181
00:09:23,920 --> 00:09:28,360
A handful of required request bodies and critical header mappings for streaming do not touch

182
00:09:28,360 --> 00:09:29,640
these yet.

183
00:09:29,640 --> 00:09:33,840
Everyone's instinct is to tweak them immediately, which inevitably breaks the whole sequence.

184
00:09:33,840 --> 00:09:35,560
Scroll instead to host.

185
00:09:35,560 --> 00:09:38,320
Microsoft's documentation whispers this as a footnote, but here's the truth.

186
00:09:38,320 --> 00:09:40,720
The host field expects the domain name only.

187
00:09:40,720 --> 00:09:46,320
If you paste a full URL with HTTPSR, SARS-SARS included or leave the trailing path to API

188
00:09:46,320 --> 00:09:50,600
ag MCP, the connector validation step fails with exquisite silence.

189
00:09:50,600 --> 00:09:55,160
It tells you everything validated correctly, then refuses to surface in co-pilot.

190
00:09:55,160 --> 00:10:01,280
Move the prefix, carve off the AP MCP and feed it the bare host, no slash, no scheme.

191
00:10:01,280 --> 00:10:05,640
That one surgical move fixes 80% of it doesn't appear in my drop-down complaints.

192
00:10:05,640 --> 00:10:07,320
Next you must adjust base URL.

193
00:10:07,320 --> 00:10:10,400
The template includes, "Age API MCP" by default.

194
00:10:10,400 --> 00:10:11,400
Remove that, why?

195
00:10:11,400 --> 00:10:15,280
Because when co-pilot concatenates paths internally, it already assumes that prefix.

196
00:10:15,280 --> 00:10:21,440
Leave it and you'll produce double druds like API, MCP, API, MCP, search, which the server

197
00:10:21,440 --> 00:10:24,440
rejects for being both redundant and ridiculous.

198
00:10:24,440 --> 00:10:26,200
Sum ruthlessly.

199
00:10:26,200 --> 00:10:28,440
Now name your creation with clarity.

200
00:10:28,440 --> 00:10:30,720
Resist the urge to call it test connector.

201
00:10:30,720 --> 00:10:33,360
Co-pilot's internal cache respects only unique names.

202
00:10:33,360 --> 00:10:37,560
Duplicate one and your new connector hides like a shy child behind the first.

203
00:10:37,560 --> 00:10:39,400
Adopt descriptive titles.

204
00:10:39,400 --> 00:10:42,640
Microsoft learn MCP or internal research context MCP.

205
00:10:42,640 --> 00:10:44,360
Then click create.

206
00:10:44,360 --> 00:10:47,640
At this stage, Microsoft's UI performs along theatrical pause.

207
00:10:47,640 --> 00:10:51,520
The connector service validates structure, registers metadata with the environment and

208
00:10:51,520 --> 00:10:53,600
distributes it across regional data centers.

209
00:10:53,600 --> 00:10:55,160
This can take up to five minutes.

210
00:10:55,160 --> 00:10:57,240
During those minutes you will be tempted to refresh.

211
00:10:57,240 --> 00:10:58,240
Don't.

212
00:10:58,240 --> 00:11:01,520
Every refresh starts caching, extending your weight like cysophers with the spin wheel.

213
00:11:01,520 --> 00:11:02,520
Go fetch a beverage.

214
00:11:02,520 --> 00:11:06,520
When validation finalizes successfully, the connector now officially exists within your

215
00:11:06,520 --> 00:11:07,520
environment.

216
00:11:07,520 --> 00:11:09,760
But being born is not the same as being useful.

217
00:11:09,760 --> 00:11:14,040
The next step, ignored by nearly every quick start blog, is schema alignment.

218
00:11:14,040 --> 00:11:19,400
MCP server responses include fields like action description, tool schema and stream token ID.

219
00:11:19,400 --> 00:11:22,560
Co-pilot expects them precisely as defined in the MCP spec.

220
00:11:22,560 --> 00:11:28,200
If your external MCP server happens to capitalize differently or nests metadata under payload.

221
00:11:28,200 --> 00:11:31,560
Response instead of data.tool, co-pilot discards it as gibberish.

222
00:11:31,560 --> 00:11:33,520
No warning, no error just again.

223
00:11:33,520 --> 00:11:34,520
Silence.

224
00:11:34,520 --> 00:11:38,800
The LLM behind co-pilot interprets that as "I don't know how to help with that."

225
00:11:38,800 --> 00:11:40,960
Congratulations, you've built a compliant void.

226
00:11:40,960 --> 00:11:44,960
To align properly, open the definition tab in your newly created connector.

227
00:11:44,960 --> 00:11:49,480
Expand the first operation, usually query or get context, and compare its responses section

228
00:11:49,480 --> 00:11:52,080
to the latest MCP schema on GitHub.

229
00:11:52,080 --> 00:11:56,760
Properties names and types so that arrays are arrays, objects are objects, and every string

230
00:11:56,760 --> 00:11:58,080
uses correct casing.

231
00:11:58,080 --> 00:11:59,400
Yes, it feels clerical.

232
00:11:59,400 --> 00:12:00,720
Welcome to diplomacy.

233
00:12:00,720 --> 00:12:02,560
Translators don't improvise grammar.

234
00:12:02,560 --> 00:12:05,360
Once alignment is complete, toggle supports streaming to yes.

235
00:12:05,360 --> 00:12:10,640
Again, the documentation places this behind an accordion, labeled optional advanced settings,

236
00:12:10,640 --> 00:12:13,160
as if it were the garnish rather than the entree.

237
00:12:13,160 --> 00:12:17,720
But co-pilot requires streamable endpoints because it renders AI responses incrementally.

238
00:12:17,720 --> 00:12:21,760
If you fail to flag it, the connector technically authenticates, but times out mid-response

239
00:12:21,760 --> 00:12:25,200
producing half sentences or worse mark down that ends in mid-word.

240
00:12:25,200 --> 00:12:27,800
Someone invariably asks, "Can't I just use sync instead?"

241
00:12:27,800 --> 00:12:32,160
No, MCP expects tokenized streams, not bulk dumps precisely to keep the conversational flow

242
00:12:32,160 --> 00:12:33,160
alive.

243
00:12:33,160 --> 00:12:36,480
Think of it as feeding the large language model through an intravenous drip rather than

244
00:12:36,480 --> 00:12:38,760
shoving an entire meal down its throat.

245
00:12:38,760 --> 00:12:40,680
The drip lets it think while it eats.

246
00:12:40,680 --> 00:12:43,120
At this juncture, you might believe success is visible.

247
00:12:43,120 --> 00:12:47,080
You head back to co-pilot studio, click add tool, filter MCP, and refresh repeatedly when

248
00:12:47,080 --> 00:12:48,560
your connector doesn't appear.

249
00:12:48,560 --> 00:12:52,560
Here's the inconvenient truth environmental propagation lags behind publication by several

250
00:12:52,560 --> 00:12:53,560
minutes.

251
00:12:53,560 --> 00:12:57,240
The workspace must sync its list of connectors with the power platform service.

252
00:12:57,240 --> 00:12:58,760
Spamming refresh delays the sync.

253
00:12:58,760 --> 00:13:00,440
The efficient admin walks away.

254
00:13:00,440 --> 00:13:04,720
The impatient one loops themselves into a temporal paradox of their own making.

255
00:13:04,720 --> 00:13:07,960
When your connector finally does appear, you'll notice something subtly different from

256
00:13:07,960 --> 00:13:09,640
Microsoft's native ones.

257
00:13:09,640 --> 00:13:11,400
Its icon lacks the built-in sigil.

258
00:13:11,400 --> 00:13:12,400
That's fine.

259
00:13:12,400 --> 00:13:13,400
You've authored something unique.

260
00:13:13,400 --> 00:13:14,400
Select it.

261
00:13:14,400 --> 00:13:16,840
Choose add and authenticate if prompted.

262
00:13:16,840 --> 00:13:21,040
The pilot now establishes a binding to that connector, retrieving its tool metadata,

263
00:13:21,040 --> 00:13:23,240
title, description, parameters.

264
00:13:23,240 --> 00:13:26,920
The presence of that metadata is proof that the handshake succeeded.

265
00:13:26,920 --> 00:13:29,560
If you see nothing, revisit your schema alignment.

266
00:13:29,560 --> 00:13:32,560
The endpoint is speaking, but co-pilot can't pass the accent.

267
00:13:32,560 --> 00:13:35,600
Two pitfalls remain both delightfully stupid.

268
00:13:35,600 --> 00:13:37,040
First, certificate validation.

269
00:13:37,040 --> 00:13:40,640
If your MCP server uses self-signed TLS and you haven't added that certificate to the

270
00:13:40,640 --> 00:13:43,840
connector environment, conversations will die on connection.

271
00:13:43,840 --> 00:13:48,520
Choose a valid certificate issued by a public CA or upload your root cert through power platform

272
00:13:48,520 --> 00:13:49,520
settings.

273
00:13:49,520 --> 00:13:51,400
Second, timeout budgeting.

274
00:13:51,400 --> 00:13:55,080
Streamable endpoints must respond with header transfer encoding chunked.

275
00:13:55,080 --> 00:13:59,920
Without it, co-pilot assumes a standard HTTP close to signal end of message and truncates

276
00:13:59,920 --> 00:14:00,920
prematurely.

277
00:14:00,920 --> 00:14:02,920
Test with curl before accusing Microsoft.

278
00:14:02,920 --> 00:14:06,160
Here's a micro story that perfectly encapsulates this ritual.

279
00:14:06,160 --> 00:14:09,480
An admin once complained that their connector suddenly stopped working.

280
00:14:09,480 --> 00:14:13,400
After forensic inspection, we discovered their hosting engineer had introduced CloudFlair

281
00:14:13,400 --> 00:14:19,440
in front of the MCP endpoint ostensibly for caching and CloudFlair in its benevolent ignorance,

282
00:14:19,440 --> 00:14:21,640
stripped the streaming headers to compress traffic.

283
00:14:21,640 --> 00:14:23,360
Result, total silence.

284
00:14:23,360 --> 00:14:24,360
Moral.

285
00:14:24,360 --> 00:14:28,280
The pipe doesn't care about your optimizations, follow the spec or enjoy debugging perigotry.

286
00:14:28,280 --> 00:14:29,400
Now the epiphany.

287
00:14:29,400 --> 00:14:32,000
This entire process isn't malicious complexity.

288
00:14:32,000 --> 00:14:35,280
Microsoft didn't set traps, it merely assumes professional patience.

289
00:14:35,280 --> 00:14:39,560
The custom connector lie persists because the UI omits the low-level steps that ensure

290
00:14:39,560 --> 00:14:40,640
correctness.

291
00:14:40,640 --> 00:14:43,360
It tells a half-way truth for the casual crowd.

292
00:14:43,360 --> 00:14:46,080
If you're still watching, you've already transcended that crowd.

293
00:14:46,080 --> 00:14:49,080
When done correctly, what you've built is more than a connector.

294
00:14:49,080 --> 00:14:50,720
It's a bridgehead for truth.

295
00:14:50,720 --> 00:14:53,440
Your co-pilot will no longer fake knowledge from Bing.

296
00:14:53,440 --> 00:14:58,760
It will perform authenticated, schema compliant, streamable context exchange with whatever intelligence

297
00:14:58,760 --> 00:14:59,880
layer you expose.

298
00:14:59,880 --> 00:15:03,960
The next time someone in your organization says, "I connected MCP, but it's not responding,"

299
00:15:03,960 --> 00:15:05,520
you'll smile grimly and reply.

300
00:15:05,520 --> 00:15:08,400
Yes, because you built a tunnel painting, not a bridge.

301
00:15:08,400 --> 00:15:13,000
Now that the bridge stands, let's verify the crossing actually works, because a beautiful

302
00:15:13,000 --> 00:15:17,280
suspension bridge is still useless until something crosses it.

303
00:15:17,280 --> 00:15:19,760
Testing and verifying the integration.

304
00:15:19,760 --> 00:15:23,040
Verification is the part everyone treats like an afterthought, until their agent smiles

305
00:15:23,040 --> 00:15:26,440
politely and says, "I don't know how to help with that."

306
00:15:26,440 --> 00:15:29,040
That phrase is co-pilot's version of a blue screen.

307
00:15:29,040 --> 00:15:32,920
The protocol failed somewhere between the connector and the model.

308
00:15:32,920 --> 00:15:36,600
Testing MCP isn't glamorous, but it's how you prove you've built a bridge and not performance

309
00:15:36,600 --> 00:15:37,600
out.

310
00:15:37,600 --> 00:15:38,960
Let's see if the litmus test.

311
00:15:38,960 --> 00:15:41,560
Does co-pilot studio actually see your connector?

312
00:15:41,560 --> 00:15:44,960
In the tools panel, filter by model context protocol once more.

313
00:15:44,960 --> 00:15:49,280
Your freshly minted title, perhaps Microsoft learn MCP, should appear beside the official

314
00:15:49,280 --> 00:15:50,280
dataverse MCP.

315
00:15:50,280 --> 00:15:52,280
If it doesn't, stop right there.

316
00:15:52,280 --> 00:15:53,480
Visibility equals registration.

317
00:15:53,480 --> 00:15:56,440
No entry means schema or hosts still misaligned.

318
00:15:56,440 --> 00:15:58,880
Assuming it appears, add the tool to your co-pilot.

319
00:15:58,880 --> 00:16:03,800
The moment you connect it, co-pilot fetches descriptive metadata from the MCP server, a dictionary

320
00:16:03,800 --> 00:16:07,560
of available tools, each with parameters and plain English descriptions.

321
00:16:07,560 --> 00:16:12,240
If you notice the description field, populate with Microsoft Docsurge or similar, congratulations.

322
00:16:12,240 --> 00:16:13,840
The handshake worked.

323
00:16:13,840 --> 00:16:15,960
Context is now being recognized, not guest.

324
00:16:15,960 --> 00:16:19,040
To verify functionality, you need a controlled question.

325
00:16:19,040 --> 00:16:23,640
Use the Microsoft Learn MCP as the proving ground because it's public, polite and unlikely

326
00:16:23,640 --> 00:16:24,640
to explode.

327
00:16:24,640 --> 00:16:28,040
Ask your agent, "How do I set up SharePoint as a knowledge source?"

328
00:16:28,040 --> 00:16:30,400
If your pipeline is intact, watch the telemetry.

329
00:16:30,400 --> 00:16:32,640
The prompt travels through this path.

330
00:16:32,640 --> 00:16:37,960
The user, custom connector, MCP server, large language model, answer with citations.

331
00:16:37,960 --> 00:16:39,880
Each leg introduces potential failure.

332
00:16:39,880 --> 00:16:45,440
When the answer returns in coherent English with markdown citations linking to Learn, Microsoft.com

333
00:16:45,440 --> 00:16:50,680
you've achieved the holy trifecta, connection, comprehension and contextualization.

334
00:16:50,680 --> 00:16:53,840
The markdown itself is proof that streaming mode functions correctly.

335
00:16:53,840 --> 00:16:57,920
You'll see the text render incrementally, sentence, pause, sentence, citation rather

336
00:16:57,920 --> 00:16:59,240
than dumping all at once.

337
00:16:59,240 --> 00:17:03,760
Not rhythm is MCP's telltale heartbeat, but if something misfires, co-pilot becomes passive

338
00:17:03,760 --> 00:17:04,760
aggressive.

339
00:17:04,760 --> 00:17:06,320
Let's decode its moods.

340
00:17:06,320 --> 00:17:07,320
Empty response.

341
00:17:07,320 --> 00:17:10,000
You type the valid query, co-pilot nodded and delivered nothing.

342
00:17:10,000 --> 00:17:13,720
That's your al-miss alignment, most likely double prefixed APMCP.

343
00:17:13,720 --> 00:17:16,200
Review the full path in your connector's definition tab.

344
00:17:16,200 --> 00:17:20,320
Remove the redundancy, republish, wait the obligatory five minutes.

345
00:17:20,320 --> 00:17:21,320
Truncated markdown.

346
00:17:21,320 --> 00:17:25,920
The answer arrives but ends mid-sentence, like a board intern walking out mid-conversation.

347
00:17:25,920 --> 00:17:29,640
Your endpoint isn't declaring transfer encoding, chunked.

348
00:17:29,640 --> 00:17:33,000
In other words, you promised streaming but sent a static dump.

349
00:17:33,000 --> 00:17:36,000
Align your headers with HTTP 1.1 streaming rules.

350
00:17:36,000 --> 00:17:37,400
I don't know how to help with that.

351
00:17:37,400 --> 00:17:39,440
This one sparks existential dread.

352
00:17:39,440 --> 00:17:43,080
It means co-pilot can reach the connector but can't pass the schema.

353
00:17:43,080 --> 00:17:47,280
Your property names diverge from the MCP spec or apparent object is missing.

354
00:17:47,280 --> 00:17:49,640
Compare again against Microsoft's reference JSON.

355
00:17:49,640 --> 00:17:51,560
The fix isn't mystical, just clerical.

356
00:17:51,560 --> 00:17:55,560
And if you receive connection failures, inspect your SSL certificate chain, self-signed

357
00:17:55,560 --> 00:18:00,040
or expired certs frequently caused silent rejections because power platform services distrust

358
00:18:00,040 --> 00:18:01,600
unverified routes.

359
00:18:01,600 --> 00:18:06,360
Replace it with one issued by a trusted CA or upload the route certificate explicitly.

360
00:18:06,360 --> 00:18:09,600
Now confirmation testing isn't merely technical, it's logical.

361
00:18:09,600 --> 00:18:12,320
Ask varied questions to detect semantic drift.

362
00:18:12,320 --> 00:18:17,160
Show me SharePoint indexing docs should trigger the same Microsoft doc search action as "How

363
00:18:17,160 --> 00:18:19,120
does SharePoint index files?"

364
00:18:19,120 --> 00:18:23,320
Different wording, identical tool choice, that's contextual understanding, not keyword retrieval.

365
00:18:23,320 --> 00:18:27,400
If responses remain stable across phrasing, your co-pilot is officially fluent.

366
00:18:27,400 --> 00:18:29,680
Here's the diagnostic trick few mention.

367
00:18:29,680 --> 00:18:32,320
Observe stream headers in your browser's network tab.

368
00:18:32,320 --> 00:18:34,800
You should see response chunks prefixed by data.

369
00:18:34,800 --> 00:18:39,120
Followed by JSON objects representing incremental tokens, each chunk corresponds to part of

370
00:18:39,120 --> 00:18:40,120
the reply.

371
00:18:40,120 --> 00:18:43,520
If you see a single massive payload at end of stream, you've lost streaming and risk time

372
00:18:43,520 --> 00:18:45,160
outs on longer queries.

373
00:18:45,160 --> 00:18:47,720
Conceptually think of testing as conducting an orchestra.

374
00:18:47,720 --> 00:18:51,600
The MCP server plays the instruments, data, schema, indexes.

375
00:18:51,600 --> 00:18:53,000
The connector wields the button.

376
00:18:53,000 --> 00:18:55,760
Your co-pilot is your conductor's ear, interpreting rhythm.

377
00:18:55,760 --> 00:19:00,600
If one musician lags or starts in the wrong key, the music collapses into noise.

378
00:19:00,600 --> 00:19:04,040
Verification is your rehearsal, aligning everyone's timing before the concert for executives

379
00:19:04,040 --> 00:19:05,160
who assume magic.

380
00:19:05,160 --> 00:19:10,640
When every section harmonizes, prompt dispatch, HTTP exchange, stream sequencing, you will

381
00:19:10,640 --> 00:19:12,520
witness a small miracle.

382
00:19:12,520 --> 00:19:17,560
Consistent, cited, enterprise-governed answers instead of the improvisational jazz co-pilot

383
00:19:17,560 --> 00:19:18,960
defaults to.

384
00:19:18,960 --> 00:19:21,200
Only then can you declare integration complete.

385
00:19:21,200 --> 00:19:25,200
You've achieved the mechanical layer of MCP, the reliable transport of context.

386
00:19:25,200 --> 00:19:27,320
So yes, delight in the neat little test results.

387
00:19:27,320 --> 00:19:28,640
But remember, they're not the finale.

388
00:19:28,640 --> 00:19:32,560
They are the diagnostic beep confirming that your AI heart now beats in time with your

389
00:19:32,560 --> 00:19:33,560
data's pulse.

390
00:19:33,560 --> 00:19:34,880
The mechanical is done.

391
00:19:34,880 --> 00:19:36,520
Next, we confront the philosophical.

392
00:19:36,520 --> 00:19:39,800
Why anyone should care that this complex symphony even exists?

393
00:19:39,800 --> 00:19:41,520
Why this matters beyond the demo?

394
00:19:41,520 --> 00:19:43,440
Here's the uncomfortable truth.

395
00:19:43,440 --> 00:19:45,840
Setting up MCP isn't a party trick.

396
00:19:45,840 --> 00:19:46,840
It's infrastructure.

397
00:19:46,840 --> 00:19:49,560
While others chase, wow, responses.

398
00:19:49,560 --> 00:19:54,160
You're building the constitution that governs how AI in your enterprise exchanges truth.

399
00:19:54,160 --> 00:19:56,720
The model context protocol standardizes that truth.

400
00:19:56,720 --> 00:20:00,760
Every query, every retrieval, all constrained by schema compliance.

401
00:20:00,760 --> 00:20:02,600
Without it, co-pilot simply embellishes.

402
00:20:02,600 --> 00:20:04,960
With MCP, it reasons within defined boundaries.

403
00:20:04,960 --> 00:20:08,800
That's the distinction between imagination and governance between a whimsical intern and

404
00:20:08,800 --> 00:20:10,760
a regulatory compliant analyst.

405
00:20:10,760 --> 00:20:12,720
For enterprises, this matters profoundly.

406
00:20:12,720 --> 00:20:17,600
A properly integrated MCP ensures that every co-pilot response originates from sanctioned

407
00:20:17,600 --> 00:20:22,160
systems, SharePoint, Dataverse, Internal APIs rather than scraped fragments drifting through

408
00:20:22,160 --> 00:20:23,160
Bing.

409
00:20:23,160 --> 00:20:26,040
Your AI now consults prime resources, not rumors.

410
00:20:26,040 --> 00:20:27,040
Security follows naturally.

411
00:20:27,040 --> 00:20:31,120
In 2025, security researchers recorded spikes in breaches tied to misconfigured custom

412
00:20:31,120 --> 00:20:36,240
connectors over permissioned endpoints, casually letting data leak across tenants.

413
00:20:36,240 --> 00:20:39,680
MCP integration done correctly reinforces zero trust principles.

414
00:20:39,680 --> 00:20:44,280
The connector acts like an embassy checkpoint, least privilege enforced, credential scoped,

415
00:20:44,280 --> 00:20:46,720
context exchanged only under defined treaties.

416
00:20:46,720 --> 00:20:50,200
Management's teams appreciate an even deeper value, auditability.

417
00:20:50,200 --> 00:20:55,800
Each MCP transaction produces explicit logs, who asked which schema replied, what metadata

418
00:20:55,800 --> 00:20:56,800
was returned.

419
00:20:56,800 --> 00:20:59,720
That's a paper trail your compliance officer can hug at night.

420
00:20:59,720 --> 00:21:04,560
Compare that with generative AI hallucinations, whose origins are somewhere on the internet.

421
00:21:04,560 --> 00:21:07,640
Future proofing seals the argument.

422
00:21:07,640 --> 00:21:13,480
As Microsoft, OpenAI and others converge toward standardized interagent protocols, MCP compliance

423
00:21:13,480 --> 00:21:16,360
will evolve from curiosity to requirement.

424
00:21:16,360 --> 00:21:21,560
Related industries, finance, healthcare, government will mandate it for AI systems exchanging contextual

425
00:21:21,560 --> 00:21:22,560
data.

426
00:21:22,560 --> 00:21:24,200
When that memo arrives, you won't scramble.

427
00:21:24,200 --> 00:21:27,480
You'll already have a compliant bridge, hamming quietly in production.

428
00:21:27,480 --> 00:21:32,840
So when colleagues dismiss your painstaking configuration as overengineering, smile calmly.

429
00:21:32,840 --> 00:21:35,560
Governance always feels like bureaucracy until the breach hits.

430
00:21:35,560 --> 00:21:36,680
Then it feels like foresight.

431
00:21:36,680 --> 00:21:41,680
Do it right once, and every co-pilot instance you deploy thereafter inherits that discipline,

432
00:21:41,680 --> 00:21:44,040
contextual awareness within controlled boundaries.

433
00:21:44,040 --> 00:21:47,840
Just the point beyond the demo, you're not just connecting a protocol, you're defining

434
00:21:47,840 --> 00:21:50,000
institutional memory in machine form.

435
00:21:50,000 --> 00:21:54,400
The next time, co-pilot answers a regulatory inquiry using the exact source and citation

436
00:21:54,400 --> 00:21:56,720
chain you authorize, remember this moment.

437
00:21:56,720 --> 00:22:00,560
The hours of URL trimming, schema matching and sanity checks.

438
00:22:00,560 --> 00:22:03,200
That's the unseen engineering beneath every responsible AI.

439
00:22:03,200 --> 00:22:07,640
Now with moral satisfaction restored and the bridge structurally sound, one question remains.

440
00:22:07,640 --> 00:22:11,600
Will you keep building disciplined intelligence or let marketing simplicity seduce you back

441
00:22:11,600 --> 00:22:12,600
into chaos?

442
00:22:12,600 --> 00:22:14,280
A inefficient thing is obvious.

443
00:22:14,280 --> 00:22:16,480
Adding MCP isn't flipping a switch.

444
00:22:16,480 --> 00:22:20,280
It's rewiring co-pilot studio's brain so it stops hallucinating and starts reasoning.

445
00:22:20,280 --> 00:22:24,600
The lazy promise of just use a custom connector collapses when you realize that connector isn't

446
00:22:24,600 --> 00:22:25,600
a door.

447
00:22:25,600 --> 00:22:29,680
It's an entire hallway you have to build, reinforce and test for leaks.

448
00:22:29,680 --> 00:22:32,880
But once completed, it changes how every future co-pilot behaves.

449
00:22:32,880 --> 00:22:36,880
What you've accomplished is structural literacy in a system designed to hide its wires.

450
00:22:36,880 --> 00:22:41,360
You taught co-pilot studio to request contacts politely to authenticate before speaking,

451
00:22:41,360 --> 00:22:44,200
to return citations instead of creative fiction.

452
00:22:44,200 --> 00:22:48,240
That discipline transforms it from a flashy chatbot into a compliant analyst.

453
00:22:48,240 --> 00:22:52,600
And yes, it required patience, schema validation and a heroic tolerance for Microsoft's refreshed

454
00:22:52,600 --> 00:22:54,520
delays, but so does anything worth trusting.

455
00:22:54,520 --> 00:22:57,080
The so-called custom connector lie isn't conspiracy.

456
00:22:57,080 --> 00:22:59,280
It's simplification marketing.

457
00:22:59,280 --> 00:23:01,480
Microsoft tells the truth suitable for demos.

458
00:23:01,480 --> 00:23:03,840
You build the one suitable for production.

459
00:23:03,840 --> 00:23:08,680
You now know that model context protocol is less plug and play, more plug and negotiate

460
00:23:08,680 --> 00:23:09,680
terms of treaties.

461
00:23:09,680 --> 00:23:14,480
Treat every connector you publish as a constitutional amendment, minimal rights, strict rules, verifiable

462
00:23:14,480 --> 00:23:15,480
outputs.

463
00:23:15,480 --> 00:23:17,800
That's how you scale governance without sacrificing velocity.

464
00:23:17,800 --> 00:23:22,200
Skip it and you'll spend your evenings explaining to executives why the chatbot quoted

465
00:23:22,200 --> 00:23:24,040
being instead of policy.

466
00:23:24,040 --> 00:23:29,040
Lock in your upgrade path, subscribe, enable notifications and let disciplined knowledge

467
00:23:29,040 --> 00:23:30,440
arrive automatically.

468
00:23:30,440 --> 00:23:35,040
No manual checks, no hand-ranging over half-working demos, just continuous delivery of intelligence

469
00:23:35,040 --> 00:23:37,200
that respects context and compliance.

470
00:23:37,200 --> 00:23:39,360
Entropy wins unless you choose structure.

471
00:23:39,360 --> 00:23:40,360
Building a structure.

472
00:23:40,360 --> 00:23:44,680
Press follow, keep building rational AI and the next update will land on schedule, like

473
00:23:44,680 --> 00:23:49,600
a properly configured connector executing exactly once, streaming truth in real time.
