## About FastMCP (TypeScript)
FastMCP for TypeScript, unrelated to the Python FastMCP, simplifies defining tools, resources and prompts and adds client sessions, authentication, OpenAPI-to-MCP conversion, image and audio content, HTTP streaming with SSE compatibility, custom HTTP routes, stateless mode and edge-runtime support for Cloudflare Workers and Deno Deploy.
