MCP Discovery API – Let AI agents find the right tools automatically
- yksanjo 9mo agoHi HN, I built MCP Discovery API, an agent-native discovery layer for Model Context Protocol servers. The problem: AI agents can only use tools you pre-configure. They can't discover new capabilities dynamically. The solution: A semantic search API that returns the best MCP server for any task. Example: Query: "I need to send emails with templates" Response: Gmail MCP server (87% confidence) + install: npx -y @anthropic/mcp-server-gmail Features: - Semantic search using OpenAI embeddings + pgvector - Real-time performance metrics (latency, uptime) - Side-by-side server comparison - 24 servers indexed, 91 capabilities tagged Tech: TypeScript, Supabase, Railway, MCP SDK Live: https://mcp-discovery-production.up.railway.app GitHub: https://github.com/yksanjo/mcp-discovery Feedback welcome!
