Learn to build Model Context Protocol (MCP) servers from scratch using LangChain in this comprehensive 36-minute tutorial. Discover how MCP standardizes the way applications provide tools and context to language models, and explore how LangGraph agents can utilize tools defined on MCP servers through the langchain-mcp-adapters library. Start with an introduction to the project scope and understand what you'll be building throughout the session. Set up your development environment using the UV package manager for efficient project management. Create a Math MCP Server to handle mathematical operations and calculations. Build a Weather MCP Server to provide weather-related functionality and data retrieval. Develop a client application that integrates with your MCP servers, demonstrating how to connect and utilize the tools you've created. Test your complete application to ensure all components work together seamlessly. Gain hands-on experience with the Model Context Protocol ecosystem and learn practical implementation techniques for building robust MCP servers that can enhance language model capabilities with custom tools and context.
