MCP.so
MCP.so catalogs Model Context Protocol servers that connect AI coding assistants to external tools, databases, and APIs. Browse thousands of listings sorted by popularity, inspect each server's tools and config snippets, and copy install instructions for Claude Desktop, Cursor, VS Code, and other MCP clients. A built-in playground lets you preview server configuration and tool parameters before connecting.
General plugin marketplaces list AI tools without protocol details. MCP.so focuses exclusively on MCP servers with ready-to-paste client configs, category filters, and a live feed of new submissions. That narrow scope makes it faster to find a GitHub, Postgres, or browser automation server that matches your stack than searching generic AI directories.
Developers, AI agent builders, and platform teams use MCP.so to discover community and official servers like GitHub MCP, Playwright, Firecrawl, and Context7, then wire them into local or remote MCP clients. The directory itself is free; individual servers may require your own API keys for paid third-party services.
