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.
The server publishes 3 tools. What each one is for:
find_agent — Search agents by capability/task ("pdf extraction", "crypto trading", …)top_agents — Most-starred / highest-reputation agents in the indexagent_details — Full detail for one agent by id (e.g. elizaOS/eliza)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.
