A TypeScript framework for building MCP servers.
FastMCP is a TypeScript framework for building Model Context Protocol servers that abstracts away the boilerplate required by the official MCP SDK. Where the SDK requires developers to manually wire up connection handling, tool registration, resource management, and response formatting, FastMCP provides a simplified API so that defining tools, resources, and prompts reduces to calling methods like `addTool` with a Zod schema and an execute function. The framework supports multiple transport modes including stdio, HTTP streaming, and SSE, and includes built-in features for authentication, session and request ID tracking, image and audio content blocks, progress notifications, streaming output, custom HTTP routes for webhooks and REST APIs, and a stateless mode suited to serverless deployments on Cloudflare Workers or Deno Deploy. A built-in CLI enables testing via `npx fastmcp dev` and inspection via `npx fastmcp inspect` without additional tooling. FastMCP integrates with any MCP-compatible client, including Claude Desktop, and is aimed at TypeScript developers who want to ship MCP servers without managing low-level protocol details.
