A TypeScript framework for building MCP servers that expose tools and resources to AI clients.

FastMCP is a server-side framework for implementing the Model Context Protocol (MCP), enabling AI assistants to interact with external tools, resources, and prompts.

The framework supports edge runtimes, serverless deployments, and includes utilities for testing and debugging MCP servers.
