FastMCP

About

FastMCP delivers a robust, production-grade server and client solution designed for modern application development. It offers flexible runtime options (Stdio and SSE), comprehensive security features including token authentication and CORS, and essential operational tools like structured logging, environment-based configuration, health checks, and Prometheus metrics. Additionally, it integrates advanced RAG capabilities with Postgres and pgvector, enabling intelligent document ingestion and querying directly through its CLI or HTTP endpoints, making it suitable for building powerful and scalable services.

Key Features

• Production-ready Stdio and SSE server runtimes with CORS, security headers, token authentication, and basic rate limiting.
• Containerization support via Dockerfile and build automation with Makefile.
• Structured JSON logging, environment-based configuration, health endpoints, and Prometheus metrics primitives.
• 0 GitHub stars
• Integrated RAG (Retrieval Augmented Generation) with Postgres, pgvector, and OpenAI API for document ingestion and querying.
• Comprehensive client CLI for listing, calling tools, and retrieving resources via SSE and stdio transports.

Use Cases

• Developing CLI tools and applications that interact with backend services and perform health checks.
• Building and deploying secure, scalable services that expose tools and resources via the FastMCP protocol.
• Implementing advanced Retrieval Augmented Generation (RAG) for intelligent document processing and question answering.
