Introduction

xmcp is a TypeScript MCP (Model Context Protocol) framework designed to help developers build, run, and ship MCP servers with excellent developer experience. It offers file-system routing for auto-registering tools and prompts, hot reloading, middleware support, extensible configuration, and flexible deployment options including Vercel.

Key Features

  • File-system routing: auto-register tools and prompts from tools and prompts directories.
  • Hot reloading for rapid development iteration.
  • Middleware toolkit for authentication and custom middleware.
  • Extensible configuration and flexible deployment targets.

Use Cases

  • Bootstrapping developer-facing tool platforms that expose custom tools and prompts as services.
  • Integrating MCP capabilities into existing Next.js or Express applications as a backend extension.
  • Providing a DX-focused foundation for teams to standardize tooling, auth, and deployment workflows.

Technical Highlights

  • Implemented in TypeScript for strong typing and developer tooling.
  • Convention-over-configuration approach simplifies registration and routing.
  • MIT-licensed open source project with community-friendly contribution model.
