MCP Hub is an open-source, community-driven directory for Model Context Protocol (MCP) servers, designed to help AI assistants like Claude and GPT discover and connect to external tools, databases, and services. It aggregates servers from 5+ sources including the official MCP Registry, npm, GitHub, Glama, and PulseMCP, with PyPI integration planned. The platform offers full-text search using PostgreSQL FTS and trigram matching, category browsing, and filtering by validation status and source. It includes Docker-based validation for secure sandbox testing, MCP handshake verification, and capability discovery. GitHub integration provides real-time stars, forks, and commit timestamps. The tech stack includes Next.js 16, React 19, Tailwind CSS 4, Radix UI, PostgreSQL via Neon, Drizzle ORM, NextAuth.js, and optional AI parsing with Anthropic Claude. Users can submit servers, browse categories, and use a command palette for quick navigation. The project is MIT-licensed and welcomes contributions.
