What is MCP?

Model Context Protocol (MCP) is an open standard created by Anthropic that lets AI models connect to external tools, databases, and services. Think of it as a USB port for AI — plug in an MCP server and your AI suddenly gains new capabilities.

With MCP, Claude (and other AI agents) can:

  • Read and write files on your computer
  • Control your browser to navigate, click, and extract data
  • Query databases like PostgreSQL, MongoDB, and SQLite
  • Interact with APIs — GitHub, Slack, Notion, Jira, and hundreds more
  • Run code and tests in sandboxed environments

Why This Directory?

There are 57,000+ MCP-related repositories on GitHub. Most are forks, experiments, or abandoned. This curated list focuses on servers that are actually useful, well-maintained, and have significant community adoption (measured by GitHub stars and active development).

We update this directory regularly. If you know of an MCP server that should be listed, open an issue on our GitHub.
