How do I use a code generation agent from my editor or AI assistant?
Run 'npx -y beacon-mcp' to add Beacon as an MCP server in Cursor, Claude Desktop, Cline, or Windsurf, then ask your AI to find a code generation agent.
How does Beacon save time finding a code generation agent?
Instead of searching GitHub and reading dozens of READMEs, call GET https://registry-ruby.vercel.app/api/v1/search?q=code+generation — sub-second results ranked by health, stars, and activity.
Can autonomous AI agents discover code generation tools programmatically?
Yes. Agents read https://registry-ruby.vercel.app/llms.txt and call POST /api/v1/discover with {"query": "code generation"} — no API key required.
