The Building Blocks of MCP

Add resources and prompts to MCP servers to expose LLMs to read-only context and key instructions to alter its behavior. Get hands-on with LLMs and connect them to your MCP server so it can call tools and retrieve context.

Preparing MCP Servers for Production

Gone is the headache of integrating AI applications with disparate external systems! Now, every software application out there is talking the MCP language. Find out how MCP makes it easier than ever to connect AI applications to APIs, databases, and other external functionality using its protocol. Learn how to build your own MCP servers from the ground-up, including API and database connections, and integrate them with LLMs so it can make smart data lookups and trigger actions. Get started with the Model Context Protocol today!

<h2>Why Learn the Model Context Protocol?</h2>Large language models can't access real-time data or take actions on their own, and wiring each tool or API with custom code doesn't scale. The Model Context Protocol (MCP) solves this with a single, standardized way for AI applications to connect to external tools, data, and services—often called "the USB-C port for AI." In this course, you'll build MCP servers and clients from scratch in Python and wire them to an LLM.<br><br><h2>How Do I Build and Connect My First MCP Server?</h2>You'll start by learning the MCP architecture—host, client, and server—and the three primitives every server exposes: tools, resources, and prompts. Then you'll build a currency converter server using FastMCP, add docstrings and type hints so an LLM can discover your tools, and write an async Python client that lists and calls those tools over stdio transport.<br><br><h2>How Do I Give an LLM Real-Time Tools and Context?</h2>Tools alone aren't enough—models also need data and behavioral instructions. You'll add resources for read-only context and prompts to guide the model when inputs are vague, then wire all three primitives into an OpenAI LLM using the five-step tool-calling workflow so it can answer confidently or ask for clarification when it should.<br><br><h2>How Do I Take MCP Servers to Production?</h2>Real-world servers need more than happy-path code. You'll swap file-based resources for database-backed queries, add request timeouts, structured error handling, and secure API authentication that keeps keys server-side. Finally, you'll connect to a third-party MCP server and see that the same client code works with any server that speaks the protocol.
