FastMCP is a TypeScript framework for building MCP (Model Context Protocol) servers with tools, resources, prompts, sessions, and authentication. It wraps the official MCP SDK with higher-level conveniences like HTTP streaming, SSE support, and a testing CLI.

Use cases

  • build an MCP server in TypeScript
  • expose tools and resources to AI assistants like Claude
  • add authentication to an MCP server
  • deploy MCP servers to Cloudflare Workers or serverless
  • test and debug MCP servers locally
  • stream tool output over SSE

When to avoid

  • you need the current stateless MCP spec (2026-07-28) — use ViteMCP instead
  • you only need the raw protocol primitives of the official SDK
