FastMCP

FastMCP is a TypeScript framework designed to simplify the process of building Model Context Protocol (MCP) servers. It provides out-of-the-box features such as session management, authentication, HTTP streaming, CORS support, error handling, and easy resource/tool/prompt definition, along with custom HTTP routes for REST APIs and webhooks. Developers can quickly spin up robust and secure MCP servers without dealing with low-level implementation details, making it suitable for anyone building advanced AI agent backends or context protocol servers.
