Build MCP servers with mcp-use

mcp-use is the full stack TypeScript framework for building MCP servers and MCP apps to plug-ins and Claude connectors

Use it to build fully typed MCP servers with tools, resources, prompts, 1 line oauth authentication adapters, middleware, production transports, a built-in Inspector, and headless tooling.

mcp-use has native first class support for MCP Apps with support for HMR both at the server and MCP App level to live preview the changes on clients like ChatGPT

Get started

Follow the guides at <https://docs.mcp-use.com/v2>.

API reference

Consult the TSDoc bundled in the installed package and the TypeScript source
