WEBVTT 00:00.360 --> 00:05.160 And of course, I should have been clear on what I just said as I was, uh, waffling away about the 00:05.160 --> 00:11.960 problem with the agents going going, uh, off track that you can use more intelligent termination conditions 00:11.960 --> 00:17.960 to make sure that this doesn't go awry and that you keep your agent interactions on rails. 00:17.960 --> 00:22.640 Don't just look for a hard coded piece of text in an agent response if you don't want to get yourself 00:22.640 --> 00:24.560 in trouble, right. 00:24.800 --> 00:26.480 Uh, there's an exercise for you. 00:26.480 --> 00:26.840 Okay. 00:26.840 --> 00:32.200 But now, in the meantime, big drum roll MCP is a topic for next week. 00:32.200 --> 00:33.800 But it is, of course, all the rage. 00:33.800 --> 00:38.800 And so I thought I'd give you a teaser, a little a little tiny sense of what it's like to work with 00:38.800 --> 00:43.640 MCP without going into any detail, because I don't want to spoil the show for next time, but let's 00:43.640 --> 00:48.400 just do a quick, quick bit of looking at MCP within Autogen. 00:48.440 --> 00:50.800 Okay, so what is MCP? 00:50.840 --> 00:58.080 Well, again, I don't want to spoil it for next time, but but MCP amongst other things is just a nice, 00:58.120 --> 01:06.620 simple, elegant way that that we can package up tools so that different models can use those tools. 01:06.620 --> 01:09.460 It's like a it's it's not an abstraction layer. 01:09.460 --> 01:11.020 It's not particularly code. 01:11.020 --> 01:13.140 It's just an agreement for a way. 01:13.140 --> 01:19.740 If you write tools in this way, then models LMS can discover them and call them in many ways. 01:19.740 --> 01:25.620 If you think of it like with something like Langshan, there is an ecosystem and Lang Chain built some 01:25.620 --> 01:31.180 code and they built some wrappers that lang chain tools and they say, if you can wrap your stuff in 01:31.180 --> 01:36.980 a Lang chain tool, then anyone else writing lang chain or lang graph will be able to use the tools 01:36.980 --> 01:38.740 that have been packaged this way. 01:39.100 --> 01:43.660 And what anthropic have done with MCP is they've said, well, actually, let's just go simpler than 01:43.660 --> 01:44.060 that. 01:44.260 --> 01:46.420 We don't necessarily need to have this glue code. 01:46.420 --> 01:52.940 We can just say, look, anyone, if you write a function a particular way, that's good enough that 01:52.940 --> 01:59.860 as long as it conforms to a particular kind of spec, then that that can be a tool that we can make 01:59.860 --> 02:01.660 available to any model we want. 02:01.980 --> 02:05.040 So it's very similar to the long chain idea. 02:05.040 --> 02:06.360 It's just more open. 02:06.400 --> 02:10.920 And rather than saying you need to be part of the lang chain lang graph ecosystem, it's just saying, 02:10.960 --> 02:15.840 look, anyone can be part of the MCP ecosystem, anyone can use this. 02:16.200 --> 02:24.360 And anthropic describes MCP as being like the USB-C connector for AI for Llms. 02:24.520 --> 02:33.000 It's just an agreed protocol, an agreed way that we can plug models into tools and also into into what 02:33.000 --> 02:36.960 they call resources, which is stuff like context for RAC. 02:37.320 --> 02:43.280 Um, so if this was just to give you some intuition for it, I didn't mean to explain it because we 02:43.280 --> 02:45.760 will explain it next time next week. 02:46.040 --> 02:52.400 But, uh, one of the things that's great about Autogen is that not only do they give you a nice little, 02:52.600 --> 02:58.280 little wrapper so that you can use any Lang chain tool, but they also give you a nice little wrapper 02:58.280 --> 03:01.160 so you can use any MCP tool. 03:01.200 --> 03:07.420 So if there's an MCP tool out there you can just use it in Autogen really, really easily and that is 03:07.420 --> 03:08.980 what we're going to do right now. 03:09.220 --> 03:11.740 And so let me take you through this. 03:11.740 --> 03:13.780 This is the whole extent of the code. 03:14.060 --> 03:17.340 Uh, we are using the assistant agent. 03:17.340 --> 03:20.300 We're using the OpenAI chat completion client. 03:20.780 --> 03:28.780 And from Autogen tools, we're bringing in this class here. 03:29.020 --> 03:32.580 There are two different types of ways of working with MCP. 03:32.580 --> 03:33.700 And this is one of them. 03:33.980 --> 03:37.220 Uh, and we will talk about those next week, of course. 03:37.580 --> 03:45.380 And in particular, uh, we are going to be using a tool called MCP fetch. 03:46.060 --> 03:51.060 And what this, this this is going to be running locally on our computers. 03:51.060 --> 03:55.180 So we're going to kick off this tool to run locally on our computers. 03:55.220 --> 04:01.780 And because it's been written a certain way, that tool is just a tool we can use from Autogen. 04:02.060 --> 04:07.970 So the key to MCP is that different people can write tools and as long as they write them a certain 04:07.970 --> 04:10.290 way, you can just use them out of the box. 04:10.370 --> 04:14.130 It's a bit like saying people could like, write a long chain tool and you can just use it out of the 04:14.170 --> 04:14.530 box. 04:14.530 --> 04:20.090 But MCP is just more open, available to any ecosystem, not just the long chain ecosystem. 04:20.210 --> 04:26.250 So MCP server fetch is an example of a tool that is open source and available, and that you can just 04:26.250 --> 04:28.610 download and run it yourself. 04:28.610 --> 04:30.530 And that is what this thing here does. 04:30.530 --> 04:37.930 It runs it locally, and it is a tool which actually runs the playwright browser in a headless mode 04:37.930 --> 04:40.450 and allows it to go and fetch web pages. 04:40.450 --> 04:46.250 So it's doing something a bit similar to what we worked on with sidekick last week, but it's just doing 04:46.250 --> 04:50.890 it not not in a way that brings up the browser, but just does it quietly behind the scenes, headless 04:50.890 --> 04:51.690 as they call it. 04:51.690 --> 05:00.010 And it will run that and then it will, it will, uh, get those tools and it will put those tools into 05:00.010 --> 05:01.770 this thing called fetcher. 05:01.890 --> 05:06.250 And we can just provide fetcher in as our tools. 05:06.370 --> 05:09.790 That's it's, just as simple as that. 05:09.830 --> 05:18.670 And so, uh, yeah, basically what we're doing here is that we're using a public online tool available 05:18.870 --> 05:23.750 that runs Playwright Browser locally and uses that to scrape the web. 05:24.070 --> 05:27.710 And we're making that tool available to our assistant. 05:27.990 --> 05:33.710 And what we're going to ask our assistant to do is review the website epodunk.com. 05:33.710 --> 05:39.150 But you can change that to any website that you want and summarize what you learn and reply in markdown. 05:39.350 --> 05:42.190 So without further ado, let's kick this off. 05:43.110 --> 05:45.550 And again, the takeaway for you is just to show. 05:45.870 --> 05:46.470 And there we go. 05:46.510 --> 05:47.070 There I am. 05:47.070 --> 05:47.950 Look at that. 05:47.990 --> 05:51.790 A technology enthusiast with a focus on coding and experimenting with llms. 05:51.830 --> 05:52.750 Sounds about right. 05:53.110 --> 05:54.190 Uh uh. 05:54.590 --> 05:55.990 And oh look, it's got a link. 05:55.990 --> 05:58.790 I wonder if that's an actual link to my LinkedIn profile. 05:58.790 --> 06:00.190 It almost certainly is. 06:00.510 --> 06:06.350 Uh, these these, uh, things are amazing at it's replied in markdown, and I'm sure it's got the right, 06:06.390 --> 06:07.270 the right links. 06:07.510 --> 06:12.090 Uh, so, um, the, the this is cool. 06:12.090 --> 06:19.170 And the reason it's cool is that we've just used a tool that someone else has written for, for running 06:19.170 --> 06:21.210 playwrights in a headless way. 06:21.570 --> 06:28.010 And we have just incorporated that tool because that tool uses this, this open standard, this standard 06:28.050 --> 06:28.810 called MCP. 06:29.090 --> 06:33.090 We're able to just drop that tool in and use it from within Autogen. 06:33.090 --> 06:38.570 So just like we could use a Lang chain tool from within Autogen, we can use an MCP tool. 06:38.610 --> 06:42.890 Anyone that's written a tool that conforms to the MCP standard. 06:42.930 --> 06:48.130 And the cool thing about MCP is that it's such an open standard that anyone can write tools, and there 06:48.130 --> 06:51.650 are websites where you can get access to lots and lots of these tools. 06:51.650 --> 06:56.970 So it's like saying, we've got access to the Lang chain ecosystem only it's a whole lot more. 06:57.130 --> 07:02.850 It's this massive open source, public community ecosystem of tools. 07:03.090 --> 07:09.810 Anyone that writes tools that conforms to the MCP standard, you can then access just like this, and 07:09.810 --> 07:16.670 you can do it from within autogen in this way and immediately have access to any of them. 07:17.190 --> 07:19.470 So it's only meant to be a teaser. 07:19.470 --> 07:22.270 I wanted to show you how you can use MCP tools. 07:22.270 --> 07:24.230 Don't worry if you don't really understand. 07:24.270 --> 07:30.110 Just get an idea and we'll we'll go through MCP and then you can come back once you fully understand 07:30.110 --> 07:35.350 it and use lots and lots of MCP tools right here from Autogen. 07:35.790 --> 07:36.990 And so there we have it. 07:37.030 --> 07:38.110 We went multimodal. 07:38.110 --> 07:39.950 We looked at structured outputs. 07:40.070 --> 07:42.190 We used tools from Lang Chain. 07:42.270 --> 07:45.710 We saw briefly teams the round robin teams. 07:45.710 --> 07:47.830 And you can experiment with more should you wish. 07:48.190 --> 07:52.550 And then we introduced a special guest in the form of MCP tools. 07:52.710 --> 07:56.590 Your teaser your preview that we will come back to shortly. 07:56.790 --> 08:00.270 And that wraps up day two of Autogen. 08:00.270 --> 08:05.790 And it is the, the probably the our last deeper foray into Autogen agent chat. 08:05.830 --> 08:11.550 Next time we switch to Autogen core, the underlying infrastructure part. 08:11.710 --> 08:12.590 I'll see you then.
