Detailed Introduction

FastMCP is a TypeScript framework designed to streamline the development of Multi-Agent Communication Protocol (MCP) servers. It abstracts away the complexities of the official MCP SDK, providing an opinionated structure, intuitive APIs, and automated boilerplate handling. This allows developers to focus on core MCP functionality, enabling rapid creation of robust, session-aware servers with features like authentication, streaming, and edge runtime compatibility, making it ideal for modern serverless and distributed architectures.
