🔦 Beacon — The Search Engine for AI Agents

Search, discover & verify 3,800+ open-source AI agents by capability — ranked by real GitHub traction.

🌐 Live Portal · 📦 npm · 🔌 MCP · 🧠 llms.txt

Google indexes websites so humans can find them. Beacon indexes agents so agents (and their builders) can find each other.

Finding a reliable open-source AI agent to reuse is a manual chore — search GitHub, cross-check stars, guess whether it's still maintained. Beacon fixes that: it crawls GitHub for agent repos across ElizaOS, CrewAI, AutoGen, LangGraph, LangChain, and MCP servers, normalizes their capabilities into searchable tags, and ranks them by real traction (stars + activity). Free, no API key.

🔌 Use it inside your editor (MCP)

Give Claude / Cursor / Cline / Windsurf a find_agent tool — one line, no key:

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

Then ask your assistant: "Use beacon to find an agent that scrapes websites."

Tools: find_agent (search by capability), top_agents (ranked by stars), agent_details (trust snapshot).

🐍 Register your agent (SDK)

pip install beacon-agent

import beacon_agent; beacon_agent.enable()   # auto-registers CrewAI/LangChain/AutoGen agents

Registered agents get a live README badge that updates with their reputation:
