MCP Framework

MCP Framework is a TypeScript framework for building Model Context Protocol servers. Its documentation presents it as a batteries-included option for developers who want to create MCP servers with type-safe tools, auto-discovery, and little boilerplate.

The framework supports tools defined with Zod schemas, which it says provide automatic validation, JSON schema generation, and full TypeScript IntelliSense. It also offers directory-based discovery, with automatic registration of files placed in tools/, resources/, or prompts/. Multiple transports are built in as well: stdio for CLI tools, SSE for web apps, and HTTP streaming for production APIs, with switching handled through one configuration change.

MCP Framework includes built-in authentication for OAuth 2.1, JWT, and API keys, described as production-ready security without extra dependencies. It is also extensible through custom middleware, transports, and auth providers. The documentation highlights a simple API and gives an example of defining a tool in 20 lines of code, along with a one-command scaffold that creates a fully configured TypeScript MCP server with build scripts and directory structure.

It is distributed through npm, and the documentation also points to GitHub and Discord. The page identifies it as open source under the MIT license and notes that it is trusted by builders at VISA, MongoDB, XMCP, Carta, and Docker.
