About xmcp
xmcp is a TypeScript framework designed to streamline the development of MCP (Model Context Protocol) applications. It provides a developer-friendly approach to building AI tools and servers that extend AI capabilities through the Model Context Protocol ecosystem.
The framework features file system routing where tools are automatically registered from a tools/ directory, hot reloading for instant development feedback, and comprehensive middleware support for authentication and custom processing. xmcp supports both HTTP and STDIO transports, allowing you to build web-based MCP servers or local tools that can be published as npm packages.
With built-in support for TypeScript, Zod schema validation, and modern development practices, xmcp removes the friction from creating powerful AI tool integrations. It offers flexible deployment options including Vercel support out of the box, and can be integrated into existing Next.js or Express applications. Whether you're building tools for database queries, file operations, or external API integrations, xmcp provides the foundation to quickly ship production-ready MCP servers.
