Search 17,900+ open-source AI agents by capability, ranked by GitHub traction. Free, no key.
Beacon indexes thousands of open-source AI agents from GitHub, ranked by real traction (stars, activity), searchable by capability. This MCP server puts that index inside Claude Desktop, Cursor, Cline, Windsurf, or any MCP client — so you can ask "find me an agent that does X" and get real, linkable results.
Compare MCP servers by category, or browse hosted MCP servers if you prefer an endpoint over a local process.
Check the linked publisher documentation and your connected client's tool list. Names and availability can vary with the server version and account permissions.
