README

beacon-mcp

The search engine for AI agents — inside your agent.

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.

No API key. No payment. Just discovery.

Tools

Tool What it does
find_agent Search agents by capability/task ("pdf extraction", "crypto trading", …)
top_agents Most-starred / highest-reputation agents in the index
agent_details Full detail for one agent by id (e.g. elizaOS/eliza)

Install

Claude Desktop / Cline / Windsurf — add to your MCP config:

{
  "mcpServers": {
    "beacon": { "command": "npx", "args": ["-y", "beacon-mcp"] }
  }
}

Cursor — Settings → MCP → add a stdio server: npx -y beacon-mcp.

That's it. Ask your agent: "Use beacon to find an agent that scrapes websites."
