Search 17,900+ open-source AI agents by capability, ranked by GitHub traction. Free, no key.
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.
| 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) |
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."
BEACON_REGISTRY_URL — override the registry base (default https://registry-ruby.vercel.app).MIT
