If you've been wanting to learn MCP, this is a great place to start. In this tutorial you'll build a simple agent with PydanticAI, and then add an MCP server called fetch, which enables web browsing. Then we'll use the Postgres MCP server to add database querying to our agent. Then we'll use Riza's remote MCP server to add a code interpreter to our agent.

Everyone is starting to realize how big of a deal Claude’s Model Context Protocol (MCP) is - it’s the first ever “standard” for connecting LLMs with services like your database, Slack, GitHub, web search, etc. It’s VERY powerful and not well understood by many, so in this video I break down everything you need to know about MCP at a high level. I go quick here unlike my usual videos, but I call out a bunch of different resources you can use to dive into anything deeper that you’re curious about - MCP architecture, building your own MCP server, integrating your custom AI agent with MCP, etc. ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Check out Stagehand, an incredible tool to crawl and scrape websites with natural language which I used in this video: https://github.com/browserbase/stagehand And here is the Stagehand MCP server that I showcased (you will need a Browserbase API key which is free to start!): https://github.com/browserbase/mcp-server-browserbase/blob/main/stagehand/README.md ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Documentation for Claude’s MCP: https://modelcontextprotocol.io/introduction List of MCP Servers on GitHub: https://github.com/modelcontextprotocol/servers Example n8n MCP Agent: https://github.com/coleam00/ottomator-agents/tree/main/n8n-mcp-agent n8n Community Node for MCP: https://github.com/nerding-io/n8n-nodes-mcp Example Pydantic AI MCP Agent: https://github.com/coleam00/ottomator-agents/tree/main/pydantic-ai-mcp-agent Dive deep into the architecture of MCP: https://modelcontextprotocol.io/docs/concepts/architecture ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ 00:00 - MCP is Blowing Up 01:55 - What is MCP? 03:12 - Making MCP "Click" (Deep Dive with Diagrams) 05:33 - How Agents Work with MCP 07:16 - Word of Caution - What MCP Isn't 08:17 - Where You Can Use MCP 09:47 - MCP Servers You Can Use NOW 11:18 - How to Set Up MCP Servers 12:08 - Using MCP Servers in Claude Desktop 13:11 - MCP Demo in Claude Desktop (Brave + Stagehand) 14:09 - Building with MCP (Servers and Clients) 15:22 - Building Your Own MCP Server 18:09 - MCP with n8n AI Agents 20:10 - MCP with Python AI Agents 21:56 - The Future of MCP 23:51 - Outro ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ Join me as I push the limits of what is possible with AI.

Note that DeepSeek-V2 paper claims a KV cache size reduction of 93.3%. They don’t exactly publish their methodology, but as far as I can tell it’s something likes this: start with Deepseek-v2 hyperparameters here: https://huggingface.co/deepseek-ai/DeepSeek-V2/blob/main/configuration_deepseek.py. num_hidden_layers=30, num_attention_heads=32, v_head_dim = 128. If DeepSeek-v2 was implemented with traditional MHA, then KV cache size would be 2*32*128*30*2=491,520 B/token. With MLA with a KV cache size of 576, we get a total cache size of 576*30=34,560 B/token. The percent reduction in KV cache size is then equal to (491,520-34,560)/492,520=92.8%. The numbers I present in this video follow the same approach but are for DeepSeek-v3/R1 architecture: https://huggingface.co/deepseek-ai/DeepSeek-V3/blob/main/config.json. num_hidden_layers=61, num_attention_heads=128, v_head_dim = 128. So traditional MHA cache would be 2*128*128*61*2 = 3,997,696 B/token. MLA reduces this to 576*61*2=70,272 B/token. Tor the DeepSeek-V3/R1 architecture, MLA reduces the KV cache size by a factor of 3,997,696/70,272 =56.9X. 2. I claim a couple times that MLA allows DeepSeek to generate tokens more than 6x faster than a vanilla transformer. The DeepSeek-V2 paper claims a slightly less than 6x throughput improvement with MLA, but since the V3/R1 architecture is heavier, we expect a larger lift, which is why i claim “more than 6x faster than a vanilla transformer” - in reality it’s probably significantly more than 6x for the V3/R1 architecture. 3. In all attention patterns and walkthroughs, we’re ignoring the |beginning of sentence| token. “The American flag is red, white, and” actually maps to 10 tokens if we include this starting token, and may attention patterns do assign high values to this token. 4. We’re ignoring bias terms matrix equations. 5. We’re ignoring positional embeddings. These are fascinating. See DeepSeek papers and ROPE.

In this video, I take a deeper dive look at the OpenAI Agents SDK and how it can be used to build a fast food agent.

Deepseek R1 - the latest and greatest open source reasoning LLM - has taken the world by storm and a lot of content creators are doing a great job covering its implications and strengths/weaknesses. What I haven’t seen a lot of though is actually using R1 in agentic workflows to truly leverage its power. So that’s what I’m showing you in this video - we’ll be using the power of R1 to make a simple but super effective agentic RAG setup. We’ll be using Smolagents by HuggingFace to create our agent - it’s the simplest agent framework out there and many of you have been asking me to try it out. This agentic RAG setup centers around the idea that reasoning LLMs like R1 are extremely powerful but quite slow. Because of this, a lot of people are starting to experiment with combining the raw power of a model like R1 with a more lightweight and fast LLM to drive the primary conversation/agent flow. Think of basically giving R1 as a tool for an agent to use when it needs more reasoning power at the cost of a slower response (and higher costs). That’s what we’ll be doing here - creating an agent that has an R1 driven RAG tool to extract in depth insights from a knowledgebase. The example in this video is meant to be an introduction to these kind of reasoning agentic flows. That’s why I keep it simple with Smolagents and a local knowledgebase. But I’m planning on expanding this much further soon with a much more robust but still similar flow built with Pydantic AI and LangGraph! ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ The Community Voting period of the oTTomator Hackathon is open!

Attention is a concept that helped improve the performance of neural machine translation applications. In this post, we will look at The Transformer – a model that uses attention to boost the speed with which these models can be trained. The Transformer outperforms the Google Neural Machine Translation model in specific tasks. The biggest benefit, however, comes from how The Transformer lends itself to parallelization. It is in fact Google Cloud’s recommendation to use The Transformer as a reference model to use their Cloud TPU offering. So let’s try to break the model apart and look at how it functions. The Transformer was proposed in the paper Attention is All You Need. A TensorFlow implementation of it is available as a part of the Tensor2Tensor package. Harvard’s NLP group created a guide annotating the paper with PyTorch implementation. In this post, we will attempt to oversimplify things a bit and introduce the concepts one by one to hopefully make it easier to understand to people without in-depth knowledge of the subject matter. 2020 Update: I’ve created a “Narrated Transformer” video which is a gentler approach to the topic: A High-Level Look Let’s begin by looking at the model as a single black box. In a machine translation application, it would take a sentence in one language, and output its translation in another.
