MCP In 26 Minutes (Model Context Protocol) — Transcript

Full transcript

1. 0:00I learned MCP for you. In the past 68
2. 0:02months, you've probably heard a lot of
3. 0:04people talk about MCP. MCP is so
4. 0:06amazing. MCP is such a game changer.
5. 0:09Well, I must tell you, they are correct.
6. 0:11I have taken a bunch of courses, build
7. 0:14MCP servers and clients for our team and
8. 0:16a couple B2B clients that we work with
9. 0:18as well. We've also included a section
10. 0:20on MCP in our AI agents boot camp. So,
11. 0:22in this video, I'm going to explain to
12. 0:24you the fundamentals of MCP, show you
13. 0:26how to use MCP servers and how to build
14. 0:28your own MCP servers as well, both with
15. 0:30code and no code. Throughout this video,
16. 0:32there will be little assessments, which
17. 0:33if you can answer these questions, then
18. 0:35congratulations, you'll be educated on
19. 0:37MCP. Now, without further ado, let's go.
20. 0:39A portion of this video is sponsored by
21. 0:41Balt. Okay, a quick overview of the
22. 0:43structure of today's video. First, we're
23. 0:44going to define MCP, talk about why it's
24. 0:46important, and how it is that we use
25. 0:48them. Then we'll be diving under the
26. 0:50hood in which I'll cover the
27. 0:51fundamentals of MCP, the concepts and
28. 0:53frameworks that govern it. Basically,
29. 0:55everything you need to know to be able
30. 0:56to use and build your own servers. But
31. 0:58it is not enough just to know all these
32. 0:59concepts. So I'll actually show you how
33. 1:01to build one as well, both with code and
34. 1:03no code. Let us now define MCP. MCP,
35. 1:06which is the abbreviation of model
36. 1:08context protocol, is defined by
37. 1:10Enthropic, the people who made it, as an
38. 1:12open protocol that standardizes how your
39. 1:13LM applications connect to and work with
40. 1:15your tools and data sources. Okay. What?
41. 1:18So first time I read that definition I
42. 1:20was like sounds important. So let me
43. 1:23actually explain it to you the way that
44. 1:24I understood it using an analogy. MCP is
45. 1:27like this USB plug here. It allows any
46. 1:30device to be able to connect to any
47. 1:32other devices to be able to work
48. 1:33together. Prior to this universal
49. 1:35standard of the USB port, if you wanted
50. 1:38to connect things to each other, like
51. 1:39say your computer to your microphone, to
52. 1:41your webcam, you would be having a very
53. 1:43bad time because all of the ports to
54. 1:45connect with each other would be
55. 1:47different, which means you would have to
56. 1:48get a bunch of different special cords
57. 1:50and different adapters to manage to get
58. 1:51them to work together. And then you
59. 1:52would have to write the software to
60. 1:54cater towards like those specific port
61. 1:55thingies, etc. Very complex, very messy.
62. 1:58But with this USB port, we're able to
63. 2:00now just connect all these devices to
64. 2:02each other and they just work. Amazing.
65. 2:04Wow. Do not be fooled. It sounds like
66. 2:06such a simple little thing, right? Just
67. 2:07like standardizing the port connectors,
68. 2:10but it amounted to massive amounts of
69. 2:11innovation with this ease of use. Now
70. 2:13before MCP existed, if you have your
71. 2:16agent and you wanted to give it access
72. 2:17to different tools and different context
73. 2:19or different types of data, you would
74. 2:20have actually faced a very similar
75. 2:21problem to the pre- USB port days
76. 2:24because each external system and tool
77. 2:25that you're trying to connect to has
78. 2:26their own specific definition of how it
79. 2:28is that you interact with it, which is
80. 2:30their special API. For example, if
81. 2:32you're trying to make a scheduling
82. 2:33agent, you would need to give it access
83. 2:34to like your calendar, your email, a
84. 2:37note-taking app, Zoom, Calendarly, and
85. 2:39you would need to custom write the code
86. 2:41for each specific tool that you want to
87. 2:43give your agent, which is a pain in the
88. 2:45ass. So that's why when Enthropic
89. 2:46proposed the model context protocol, the
90. 2:48MCP, which would standardize the ways
91. 2:50that we interact with all of these
92. 2:52external softwares, everybody was like,
93. 2:54amazing. Wow, so good. Now your agent is
94. 2:57able to have access to all of these
95. 2:59different external softwares and tools
96. 3:01using the same protocol. Within just
97. 3:03months that the number of tools that you
98. 3:04can give your AI agents now, which are
99. 3:06called MCP servers massively exploded to
100. 3:08thousands. Now there's over 20,000
101. 3:10pre-built MCP servers that you can just
102. 3:12grab and give your AI agent. Here is
103. 3:14just a small sample. Now, anybody can
104. 3:16easily write them, publish them, and use
105. 3:18them. Let me actually show you exactly
106. 3:20how easy it is to use an MCP server.
107. 3:22Like say for example, I'm looking at
108. 3:23these MCP servers here. You can pick any
109. 3:25of them, but let's just pick like Alpha
110. 3:27Vantage for example. It is a MCP server
111. 3:29that enables LLMs and aentic workflows
112. 3:31to seamlessly interact with realtime and
113. 3:33historical stock market data through the
114. 3:35model context protocol. Okay, great. So,
115. 3:37you can get access to stock market data.
116. 3:41You copy this stuff which allows your LM
117. 3:43application to have access to the MCP
118. 3:45server. copy it into your LM application
119. 3:47like for example cloud code if you want
120. 3:49to give the tool to cloud code and voila
121. 3:51you'll be able to have access to the MCP
122. 3:54server and all the different tools that
123. 3:55are defined on the server then you can
124. 3:57do something like plot the coffee stock
125. 4:01market prices for the past 10 years then
126. 4:05Claude will say Claude wants to use the
127. 4:07coffee function from Alpha Vantage are
128. 4:09we going to allow this and we'll be like
129. 4:10okay allow once using that tool was able
130. 4:13to get the coffee price data and now
131. 4:14it's going to created interactive
132. 4:16visualization and there you go, coffee
133. 4:17global prices with all of this
134. 4:19information. Oh my god, coffee is so
135. 4:21expensive these days. So yes, this is
136. 4:23pretty much how easy it is to use any
137. 4:25MCP server now. And I can also very
138. 4:27easily switch what is called the host
139. 4:29which is cloud code in this case to
140. 4:30something else like NA10 for example or
141. 4:32my own custom AI app. So let's now
142. 4:34actually dive into the foundations of
143. 4:36MCP so you will exactly understand what
144. 4:38just happened here and how to build your
145. 4:40own MCP servers as well. And by the way,
146. 4:42MCP servers are actually even more
147. 4:43powerful than just giving your agents
148. 4:45tools. There's a lot more that you can
149. 4:47actually do, which is why people are
150. 4:48able to actually build these MCP servers
151. 4:50and then sell them.
152. 4:53The best course that I found which
153. 4:54covers the foundations of MCP is
154. 4:56Anthropic's own course in collaboration
155. 4:58with deep learning.AI called MCP, build
156. 5:01rich context AI apps with anthropic. The
157. 5:03course starts with explaining basically
158. 5:05why is MCP important. So I already
159. 5:07covered most of that. Um but I do like
160. 5:09the diagrams that they gave which shows
161. 5:10that see before MCP there was fragmented
162. 5:13AI development with each AI app you
163. 5:16would need to have a custom
164. 5:17implementation custom prompt logic
165. 5:19custom tool calls and custom data
166. 5:21access. And you got to do that for all
167. 5:22of them versus with MCP which is a
168. 5:24standardized AI development for each MCP
169. 5:27compatible application you're able to
170. 5:29have access to a lot of different types
171. 5:31of MCP servers. For example, you can
172. 5:33have access to a data store MCP server
173. 5:35so that you can have access to data
174. 5:36stores. You can have a CRM MCP server so
175. 5:38that you can have access to CRM systems
176. 5:41and a version control MCP server so you
177. 5:42can have version control software. All
178. 5:44plug-andplay and the other way around as
179. 5:46well. Every time you build an MCP
180. 5:47server, it would be reusable by various
181. 5:49AI applications like a Google Drive MCP
182. 5:52server that has access to Google Drive
183. 5:53functions that can be used by MCP
184. 5:56compatible AI assistant, MCP compatible
185. 5:58AI agent, and an MCP compatible desktop
186. 6:00app or IDE too. All right. Next
187. 6:02important concept to understand is the
188. 6:03client server architecture. Within the
189. 6:06components that make up MCP, there are
190. 6:09three different components. The host,
191. 6:11client, and server, HCS for short. And
192. 6:14the way that they relate to each other
193. 6:15is the host houses the MCP client, which
194. 6:18goes through the MCP protocol in order
195. 6:20to have access to the MCP server. Hosts
196. 6:23are LM applications that want access to
197. 6:25certain data or tools through MCP. As I
198. 6:28showed earlier, the cloud desktop is an
199. 6:29example of a host. NA10 is also an
200. 6:31example of a host. You can also have
201. 6:33IDs, AI agents. Really any large
202. 6:35language model application can be a
203. 6:36host. Now the host wants to use the MCP
204. 6:39servers which are the lightweight
205. 6:40programs that expose different
206. 6:41capabilities like the servers here like
207. 6:43alpha advantage we talked about earlier
208. 6:45that's able to get real-time historical
209. 6:47stock data. Uh there's also time
210. 6:49provides time and time zone conversion
211. 6:51capabilities. Cherry studio that's used
212. 6:54for LM provider support like AI
213. 6:56assistance and conversions, documented
214. 6:57data processing. Postgress SQL to
215. 6:59provide readonly access to Postgress SQL
216. 7:01databases allowing schema inspection and
217. 7:03execution of readonly queries, GitLab,
218. 7:05Reddist, etc., etc. There is a lot. Now,
219. 7:08in order for the host to actually have
220. 7:11access to these MCP servers, they need
221. 7:13to maintain what is called an MCP
222. 7:15client, which lives inside a host and
223. 7:17evokes the MCP protocol to maintain that
224. 7:20one-on-one connection with the server.
225. 7:22Got it? MCP client lives in MCP host to
226. 7:25invoke the MCP protocol in order to have
227. 7:28access to the MCP servers which the
228. 7:30players being HCS host client and
229. 7:33server. All right, time for a little
230. 7:34quiz for the example that I showed
231. 7:36earlier which allowed cloud desktop able
232. 7:38to access historical stock data alpha
233. 7:41vantage and cloud code. Which is the
234. 7:43host and which is the server? Put your
235. 7:45answer into the comments. Okay, let's
236. 7:48now talk about what are the things that
237. 7:49are actually contained within an MCP
238. 7:51server. Well, there are three major
239. 7:54things. These are tools, resources, and
240. 7:56prompt templates. TRP tools, which are
241. 7:59the things that we've kind of seen the
242. 8:02most of are functions and tools that can
243. 8:04be invoked by the client. So, these are
244. 8:06these things over here like time series,
245. 8:09intraday, time series, daily, blah blah
246. 8:11blah, symbol search, global quote. Also,
247. 8:13stuff like sending a message in Gmail,
248. 8:15calculator, retrieval and search,
249. 8:17sending a message, updating database
250. 8:18records. All of these are tools. But
251. 8:21that is actually not all. You can also
252. 8:23have what are called resources which are
253. 8:25readonly data that is exposed by the
254. 8:27server. So this is the data that the
255. 8:29client is able to query but cannot
256. 8:31change. For example, there are certain
257. 8:32files like markdown notes that's
258. 8:34contained within the server that you
259. 8:36might want to read. Maybe it's tracking
260. 8:38logs. Say for example, every time you're
261. 8:39calling a weather app tool and you're
262. 8:41getting that data, you might want to
263. 8:43actually save a record of all the
264. 8:45different weathers that you've
265. 8:46collected. So at some point you might
266. 8:47want to compile that together and make
267. 8:49like a visualization or something,
268. 8:50right? It would not be very efficient if
269. 8:51every single time you had to go collect
270. 8:53a weather data point. You would have to
271. 8:55like use the tool and spam the tool over
272. 8:57and over and over again. It could also
273. 8:58contain just database records of stuff.
274. 9:00Like for example, there's just like
275. 9:02information that you're storing like
276. 9:03contracts, meeting recordings, and
277. 9:05notes. Then there's also prompt
278. 9:07templates. These are structured prompt
279. 9:09blueprints so that you don't have to
280. 9:10force your user to have to come up with
281. 9:12their own prompts. Like for example, if
282. 9:14you are someone who's trying to use an
283. 9:15MCP server that uh is able to summarize
284. 9:18like a certain transcript from a meeting
285. 9:20and then generate a report based upon
286. 9:22it, you could just write something like,
287. 9:23oh, summarize this transcript into key
288. 9:25action items, then generate a report,
289. 9:28right? Like you could write something
290. 9:29like that, but that probably won't yield
291. 9:31the best results. So instead, the people
292. 9:32that actually built the MCP server can
293. 9:35put within their MCP server a prompt
294. 9:37template that is much more flushed out
295. 9:39that's able to actually extract the
296. 9:41insights and generate the report in a
297. 9:42much better fashion so that the user all
298. 9:44they have to do is input like some
299. 9:46specifics into that template. This takes
300. 9:48the burden of the prompt engineering
301. 9:50from the user. As a full example, you
302. 9:52can have like a SQLite MCP server which
303. 9:55gives access to like a database which is
304. 9:57the SQLite database. Don't worry if you
305. 9:59don't know what that is. is basically
306. 10:00just like a database that can store
307. 10:01information. Anyways, so you can have
308. 10:03tools that allow you to read the SQL
309. 10:06database to insert information into the
310. 10:08database to change the information in
311. 10:10the database and to delete information
312. 10:11from the database. In addition to that,
313. 10:13there is a resource that is logging all
314. 10:16of the changes that are happening to the
315. 10:17database so you have a historical track
316. 10:19record of what's happened. And there's
317. 10:20also some prompt templates that
318. 10:22incorporates the best practices to
319. 10:24interact with that database. Make sense?
320. 10:25All right, time for our next little
321. 10:27assessment. Please answer the questions
322. 10:28on screen now and put it into the
323. 10:31comments so you are following along. MCP
324. 10:33is all about giving your agents more
325. 10:35context so that they can do really
326. 10:36powerful things. So when you're ready to
327. 10:38deploy your AI agents with a lot more
328. 10:40functionalities and you want really good
329. 10:41UI, NA10 plus Bolt is a really powerful
330. 10:45combination and you don't need to write
331. 10:46a single line of code or you can just
332. 10:48directly build via Bolt. Bolt can take
333. 10:50you from an idea to a fully functional
334. 10:52product within minutes. Whether that is
335. 10:54software for your team, an internal tool
336. 10:56or a website. It has everything that you
337. 10:58need, whether that's hosting, backend,
338. 11:00database, off, domains, and even SEO.
339. 11:03One of the things I really like about
340. 11:04Bald is that it seamlessly handles the
341. 11:06entire process so that you can focus on
342. 11:08building real things as opposed to
343. 11:11handling infrastructure. You don't need
344. 11:12to handle like setup, configs, war,
345. 11:14external tools. Bolt puts the most
346. 11:16powerful tools used by developers into
347. 11:18your hands with an intuitive chat
348. 11:20interface. It really is as simple as
349. 11:22this. So, here we have the Bolt new
350. 11:24landing page. And we can just type
351. 11:26something like build an app that blurs
352. 11:29out people's faces in pictures and just
353. 11:33click build now and then let it do its
354. 11:36thing. Of course, you can go into a lot
355. 11:38more details and have a lot of like
356. 11:39specific specs within the app as well.
357. 11:42And look at that. Here we have this
358. 11:44application and let's actually try it
359. 11:45out. We will put an image. Here is a
360. 11:49picture of me when I was still a little
361. 11:50Tina. And there you go. We have the
362. 11:52original and then we have the blurred
363. 11:54version. And you can download the
364. 11:56blurred image as well. As well as you
365. 11:58keep building, you can include a lot
366. 11:59more features and tweak things however
367. 12:01it is that you want. Let Bald do the
368. 12:03heavy lifting so you can focus on your
369. 12:04vision instead of fighting bugs. You can
370. 12:06try out Bald V2 for free today at this
371. 12:09link over here, also linked in
372. 12:10description. Now, back to the video.
373. 12:12Okay, so the final concept that I want
374. 12:14to cover for MCP before diving into
375. 12:16actually building them is the
376. 12:18communication life cycle. The way that
377. 12:19the MCP client and the MCP server
378. 12:22communicate with each other. The first
379. 12:23step is the initialization when the MCP
380. 12:25client interacts with the MCP server
381. 12:27being like, hey, I would like things
382. 12:29from you now and they initiate a
383. 12:31connection. Then you have the message
384. 12:33exchange phase when the MCP client makes
385. 12:35a request to the server. for example
386. 12:37like I want to use this tool and the MCP
387. 12:40server goes like okay and gives it back
388. 12:42which is the response. So you do that
389. 12:44exchange the messages and then finally
390. 12:46there's the termination phase when the
391. 12:48client and the server terminate and stop
392. 12:51interacting with each other. Now the way
393. 12:52that the messages are done is called a
394. 12:54transport. The transport handles the
395. 12:56underlying mechanics of how messages are
396. 12:58sent and received between the client and
397. 13:00the server. And there are two different
398. 13:01categories of how transports work. First
399. 13:03one is when the server is running
400. 13:05locally like your MCP server and your
401. 13:07host all of this is within a single
402. 13:09machine. The analogy that I like to give
403. 13:11here is say that your MCP client is like
404. 13:13the diner and the chef is like your MCP
405. 13:16server who is going to be the one
406. 13:18preparing the food for your diner. Now
407. 13:19for the server and the client running
408. 13:21locally, it'll be like just you and your
409. 13:23friend cooking at home with like a
410. 13:24notebook. You as the chef is just like
411. 13:26cooking it and maybe you're just like
412. 13:28writing down what it is that you're
413. 13:29doing and like just passing a note to
414. 13:30your friend the diner for some reason.
415. 13:32So they're like keeping updated about
416. 13:34what's happening while you're cooking.
417. 13:35That is like the standard out a running
418. 13:37log that's just like living locally
419. 13:39between you guys. You don't need to rely
420. 13:41on like a waiter or a cashier or
421. 13:43anything like that. The other category
422. 13:44of transports is for remote servers. So
423. 13:46these are servers that live in other
424. 13:48machines on the cloud somewhere else.
425. 13:50And there are two different approaches
426. 13:51to interact with a remote server. The
427. 13:53first one is called HTTP plus SSE which
428. 13:55is server sent events. Don't worry so
429. 13:57much about the terminologies. It
430. 13:58supports what is called a stateful
431. 14:00connection. Going back to that analogy,
432. 14:02in this case, you would have to like
433. 14:03leave your house and say you're at a
434. 14:04restaurant. You, as a diner, would sit
435. 14:06down at the restaurant. You're the
436. 14:08client, and you would interact with a
437. 14:10waiter, which is a server, and you would
438. 14:12tell it stuff like, "Oh, here's my
439. 14:13table. Here's the appetizers that I want
440. 14:15to order, blah, blah, blah." And then
441. 14:16your server would like bring you those
442. 14:17things, and say if you want to order
443. 14:19like the same drink again, you could
444. 14:20just say something like, "I'll like to
445. 14:21have the same drink again." And you
446. 14:22don't have to like exactly specify
447. 14:24whatever it is that you ordered the
448. 14:25first time. So this is called a stateful
449. 14:27connection because the server maintains
450. 14:28the state of it like remembering the
451. 14:30knowledge the memory of what you ordered
452. 14:31all this information throughout the
453. 14:33entire interaction. Now there's also
454. 14:35what is called stateless stateful
455. 14:37stateless. This kind of transport
456. 14:38supported by a streamable HTTP. To be
457. 14:41stateless is sort of like if you go to a
458. 14:43fast food restaurant as opposed to like
459. 14:45a sitdown restaurant. Like if you're at
460. 14:47McDonald's for example, you would order
461. 14:48like a Big Mac and I don't know like
462. 14:50fries. But then like if you want to get
463. 14:52something else, you want to also get
464. 14:53like chicken nuggets, you would actually
465. 14:55have to go and like input your order all
466. 14:57over again and get like a new ticket and
467. 14:59you have to wait again. The cashier
468. 15:00that's clashing you out, the server
469. 15:01doesn't actually remember everything
470. 15:03that you ordered previously. So that's
471. 15:05why it's called stateless because it
472. 15:06doesn't remember all of the knowledge
473. 15:08that came with your prior interactions.
474. 15:10Each request is independent of each
475. 15:12other. So without going into way too
476. 15:13much detail about this like the
477. 15:14streamable HTTP is the preferred
478. 15:17transport method because it's able to
479. 15:19support both stateful and stateless and
480. 15:21there are instances in which you want to
481. 15:23have like stateful interactions and
482. 15:25instances in which you want to have
483. 15:26stateless interactions as well. So this
484. 15:28section might sound a little bit like
485. 15:29detailed and theoretical but it does
486. 15:31become very important when we're
487. 15:33actually going to be using our MCP
488. 15:35servers and building our MCP servers
489. 15:37which is right after I give you this
490. 15:38final little assessment.
491. 15:44Okay, I'm going to show you the no code
492. 15:46implementation of building your very own
493. 15:47MCP server now. And we're going to be
494. 15:49doing this by using n10. So you can do
495. 15:52stuff like send an email to Tina with
496. 15:55the address tina@ lonelyotopus.com
497. 15:59asking her if she wants to grab a coffee
498. 16:04sometime.
499. 16:07Execute workflow. Press enter. goes
500. 16:11through this. We can see that it's
501. 16:12accessing the AI agent is accessing the
502. 16:14MCP client which is here. It contains
503. 16:17the ability to have a calculator and
504. 16:19also the tool that allows to send a
505. 16:21message to Gmail. So, it's able to
506. 16:23access the tool to send a message to
507. 16:25Gmail so that you will be able to get
508. 16:27this email. Hi Tina, I hope this message
509. 16:30finds you well. I was wondering if you
510. 16:31like to grab a coffee sometime. Let me
511. 16:32know what works for you. Best regards.
512. 16:33Email was automatically sent with NATO.
513. 16:35Okay. So, how to build this from
514. 16:37scratch? start off with a fresh new
515. 16:39workflow using NA10. If you have no idea
516. 16:41what NA10 is and you're not familiar
517. 16:43with it at all, check out this video
518. 16:44over here. I go into details about how
519. 16:46to build AI agents using NA10. I'm not
520. 16:48going to go into this here, so the video
521. 16:49is not super long, but basically it's a
522. 16:51no code low code tool that allows you to
523. 16:53build workflows. Also allows you to
524. 16:54build MCP servers. So you have your
525. 16:56server trigger over here and you want to
526. 16:58add some tools. Like for example, we can
527. 17:00add the calculator tool, which is just
528. 17:02like the ability to calculate things and
529. 17:04do math. Not super innovative but yes.
530. 17:07And then we can also add the email tool.
531. 17:09So maybe like a Gmail tool. And in here
532. 17:13we need to set up the credentials like
533. 17:14create new credential. You can kind of
534. 17:16go through the process. So all you have
535. 17:19to do is like sign into your Gmail um
536. 17:21which I will do here. And then you'll
537. 17:23have the account that is connected. Yay.
538. 17:26Then um because we just want to send
539. 17:28emails here. So the operation here is
540. 17:29going to be send. So for two we're going
541. 17:31to let the model decide these. So, let
542. 17:33the model decide the subject. Let's al
543. 17:36also let the model decide uh we'll have
544. 17:38the email type HTML and the message.
545. 17:42Let's also let the model decide that as
546. 17:43well. Wonderful. Amazing. So simple.
547. 17:45Right now, let's save this. Now, in
548. 17:48order to actually use our server, we
549. 17:50want to come here, make sure that it's
550. 17:52active. So, the server itself is going
551. 17:54to be active. And we want to take this
552. 17:57production URL. So, this allows access
553. 17:59to the server. Now I have another
554. 18:01workflow over here which is an AI agent
555. 18:03in which you can prompt it directly and
556. 18:05respond also attach the open AI chat
557. 18:07model here. So in order to add the MCP I
558. 18:10can click the MCP client tool the
559. 18:12endpoint we're going to copy paste what
560. 18:14we got from the MCP server and here in
561. 18:17the server transport see we have the
562. 18:19server send events which is deprecated
563. 18:20and the HTTP streamable the two
564. 18:22different transport right so we're going
565. 18:24to click HTTP streamable transport and
566. 18:26we don't need to change anything else
567. 18:28over here. Wow. Now we have the MCP
568. 18:30client. So let's actually test it out.
569. 18:32Let's actually do math this time.
570. 18:34Calculate 10
571. 18:3711 * 99.
572. 18:41We can see here that the AI agent goes
573. 18:44over here. Human says calculate 11 * 99.
574. 18:46It goes to the MCP client and it uses
575. 18:48the tool cal the calculator tool which
576. 18:50we have. And it says useful for getting
577. 18:52the results of a math expression. And
578. 18:54then the open AI chat model was able to
579. 18:55get the results by using the MCP client.
580. 18:58And then we were able to get the final
581. 18:59result here with the output being the
582. 19:01result of 11 multipi by 99 is 1,089.
583. 19:05Yay. See how easy it is. There's a lot
584. 19:08that you can do with this. Of course,
585. 19:09you can add like so many more tools into
586. 19:11your MCP server. And you also don't need
587. 19:13to have NAN as your host. We can easily
588. 19:16switch out the host for something else.
589. 19:17Like for example, maybe you want to
590. 19:19change out the host for cloud desktop.
591. 19:20So what we need to do is go on cloud
592. 19:23desktop. So go on help, type in
593. 19:25developer. So switch to developer mode
594. 19:28and then under developer open the claw
595. 19:30desktop config file. So this should be
596. 19:33empty. You can open it with whatever
597. 19:35text editor. So I'm here I'm just using
598. 19:36VS code for it. And you want to copy
599. 19:38paste this. So this is defined MCP
600. 19:40server and we're using NAN because
601. 19:42that's where the server is and we are
602. 19:44using SSE over here. And over here just
603. 19:48paste the endpoint here. So command S or
604. 19:52control S. Save it. Restart Claude and
605. 19:56wow amazing. We have NA10 over here
606. 19:58under the tools and includes send a
607. 20:00message in Gmail and the calculator. And
608. 20:02then you can do the same thing here.
609. 20:04Send an email to Tina@ lonely
610. 20:08octopus.com
611. 20:09asking her to host an octopus party.
612. 20:13Click enter.
613. 20:15See it'll say over here Claude wants to
614. 20:17use send a message in Gmail from NA10.
615. 20:19And you can click allow once to allow it
616. 20:21to use the tool from the MCP server. And
617. 20:24moment of truth, we have over here, "Hi
618. 20:27Tina, I hope this message finds you
619. 20:28well. I want to reach out to see if
620. 20:29you'd be interested in hosting an
621. 20:30octopus party. I think it'll be a
622. 20:32wonderful event and you'll be the
623. 20:33perfect host for it. Let me know if
624. 20:34you're available and interested. Looking
625. 20:35forward to hearing from you. Best
626. 20:36regards. Yes, automatically sent with
627. 20:38NAT." Voila. See, super easy, right?
628. 20:41Okay. So, now I want to show you the
629. 20:42code implementation of doing this. Now
630. 20:44with code you are able to do a lot more
631. 20:47than this no code approach. I think the
632. 20:49no code approach is amazing. It's great,
633. 20:50right? It's really accessible and easy
634. 20:52to use. Remember we talked about earlier
635. 20:53about having like additional resources
636. 20:55and also prompt templates. You as of
637. 20:57right now cannot do that using NAT. You
638. 21:00can't actually put in the prompt
639. 21:01templates and specify those and you also
640. 21:02can't put in additional resources as
641. 21:04well. And in the code implementation you
642. 21:06can. So I'm not going to go and show you
643. 21:08every single line of code right now
644. 21:10because I don't want to make this video
645. 21:11like super duper long. But I want to
646. 21:13show you like the snippet of these are
647. 21:14the tools that we're going to be using
648. 21:16and this is how you can actually get it
649. 21:17to run. Okay. So for this code demo,
650. 21:19we're going to be using cloud desktop as
651. 21:22the host and I'm going to showcase a
652. 21:24simple MCP server that's able to provide
653. 21:26tools, resources, and prompts for
654. 21:28working with Google Sheets and Google
655. 21:30forms. So we can tell that the MC3
656. 21:32server is connected because if you go to
657. 21:34G Sheets over here, which is the MCP
658. 21:36server name, you can see all the tools
659. 21:37that are contained over here. So I have
660. 21:39a lot of different spreadsheets that are
661. 21:41available. So let's actually ask list
662. 21:42out the spreadsheets that are available.
663. 21:49It will want to use the list
664. 21:50spreadsheets. So this is the tool and it
665. 21:53tells us that we have 20 spreadsheets
666. 21:55that are available in the Google account
667. 21:57like NA10 form, anonymous feedback, the
668. 22:00only octis alumni blah blah blah etc.
669. 22:02All of these different ones. Would you
670. 22:04like me to read the data from any of
671. 22:05these spreadsheets here? I can say use
672. 22:08read sheet to get the columns
673. 22:13of the anonymous
674. 22:17feedback spreadsheet.
675. 22:20So it wants to use read sheet and this
676. 22:22is actually a resource. So it allows you
677. 22:26it's a readonly file where you can
678. 22:28actually read what the column names are.
679. 22:30You can see the spreadsheet ID and the
680. 22:33information that's contained over there.
681. 22:35And finally, I want to show you what it
682. 22:36looks like to use some of the prompt
683. 22:38templates. So, if we click over here,
684. 22:40add from sheets, here are some of the
685. 22:43prompt templates. So, let's click
686. 22:44analyze sheet data. And we can say use
687. 22:46this to analyze the anonymous
688. 22:52pretty spell anonymous
689. 22:55feedback
690. 22:57spreadsheet
691. 22:59and create a dashboard just to make it
692. 23:02look pretty.
693. 23:04And we can see here is what the prompt
694. 23:06template actually looks like. And it
695. 23:09shall do this. Let it do its thing. So
696. 23:12while it's doing that, let me actually
697. 23:13show you what the code looks like and
698. 23:14how to run this MCP server. Here's the
699. 23:16readme. If you follow these
700. 23:17instructions, you'll be able to run this
701. 23:18MCP server yourself. You can see that
702. 23:21the tools that it contains include
703. 23:23things like list spreadsheet, read the
704. 23:25sheet, write the sheet, append the
705. 23:26sheet, etc. It also has the resource
706. 23:29where you can use the sheet in order to
707. 23:31access sheet data as the resource. And
708. 23:33it has prompt templates including
709. 23:34analyze sheet data which is template for
710. 23:36analyzing sheet data. Creating report
711. 23:38template. So a template for creating
712. 23:40report spreadsheets and form to sheet
713. 23:42which is a template for form to sheet
714. 23:44workflow in the code itself. Not going
715. 23:47into too much detail over here. You can
716. 23:50see that after we define the credentials
717. 23:52the way that you can define these tools
718. 23:54that you can decorate the function. So
719. 23:56you know that's MCP tool. So this one is
720. 23:58the function for listing the
721. 23:59spreadsheet. This one is for reading the
722. 24:01sheet etc. And then the way that you can
723. 24:04show that it's a resource is that you
724. 24:06just decorate it so that you know that
725. 24:07it's a resource. So get sheet resource.
726. 24:10And here are the prompt templates
727. 24:12themselves. So they're actually
728. 24:13hardcoded directly in these different
729. 24:15prompt templates. So let's go back to
730. 24:17claude here and see what is happening
731. 24:19there. Great. We see that it analyzed
732. 24:22the anonymous feedback spreadsheet. So I
733. 24:25read that information, analyzed the data
734. 24:27using the template that we provided and
735. 24:29it actually created a dashboard as well.
736. 24:31So here is the dashboard. So total
737. 24:34response is 43. The average MPS score
738. 24:37which is the net promoter score is 4.9
739. 24:395.98 blah blah blah all these things. So
740. 24:42it tells you information about this
741. 24:45different categories uh how the study
742. 24:47plan progress tracker is qualitative
743. 24:50information about what attracted
744. 24:52students to our boot camp and insights
745. 24:55as well. So different types of
746. 24:57information including what works well
747. 24:59and what doesn't work well etc etc. So
748. 25:01yeah there you go. This is the code demo
749. 25:04of an MCP server. I hope you can see
750. 25:06that there's so much potential for so
751. 25:08many different types of things that you
752. 25:09can build now that you have the ability
753. 25:11to create your own MCP servers. You can
754. 25:13of course also change your host. You use
755. 25:14this MCP server with NA10 uh with your
756. 25:18own agent with your any large language
757. 25:20model application that you build as
758. 25:22well. The possibilities are endless. So
759. 25:24if you do want to dig deeper into this,
760. 25:26I highly recommend that you actually
761. 25:27check out the anthropic deep learning AI
762. 25:29course that goes into the exact
763. 25:31implementation step by step how to build
764. 25:33this entire MCP server. It is really,
765. 25:35really, really powerful. There are of
766. 25:36course a lot of other ways that you can
767. 25:37implement MCP servers as well, both code
768. 25:40and no code approaches. I also really
769. 25:41like this one by Network Chuck where he
770. 25:44goes into a lot of detail about how to
771. 25:45use Docker in order to do this. So I'm
772. 25:47going to link his video below as well. I
773. 25:48really recommend that you check it out
774. 25:49if you're interested in implementing it
775. 25:51using Docker. But for this video, I'm
776. 25:53going to end it here. I hope that you
777. 25:54now have an excellent fundamental
778. 25:56understanding of MCP and how to actually
779. 25:58build them yourself, too. Here is the
780. 26:00final little assessment. Please answer
781. 26:01these questions and put them into the
782. 26:03comments.
783. 26:06Hope you enjoyed this video and thank
784. 26:08you so much for staying until the end.
785. 26:09I'll see you guys in the next video for
786. 26:11live stream.
787. 26:17[Music]
