Show HN: MCP Harbor – An MCP Registry

A new registry called MCP Harbor has launched, indexing 20 Model Context Protocol servers that expose 121 tools, 8 of which are hosted remotely. The directory lists servers from Brave, Cloudflare, GitHub, Hugging Face, Linear, Notion, Sentry, Microsoft's Playwright team, Cognition's DeepWiki, Exa, Context7 and the official Model Context Protocol reference set, and can be queried by an agent via its /llms.txt endpoint.
