The complete directory of public MCP servers — connect any AI host to databases, files, APIs, cloud services, browsers, and more. One protocol, every integration.
Model Context Protocol (MCP) is an open standard by Anthropic that lets AI applications connect to external data sources and tools through a unified interface — like a "USB-C for AI." Instead of building custom integrations for each AI app, you build one MCP server that works everywhere.
Architecture: A host (Claude Desktop, Cursor, VS Code) runs an MCP client that connects to any number of MCP servers, each exposing tools, resources, and prompt templates.
