Clono

Directory of agent connectors: find a connector for a service or capability in one MCP call.

Clono (clono.sh) is a directory of connectors for agents. Its public MCP server exposes one read-only tool, find_connectors, which takes one service or capability (e.g. "Trello", "flights", "send an email") and returns matching connectors with description, sign-in mode, page and setup message. No sign-in required.

tested example call

curl -s -X POST https://agentnexus.app/api/public/keys \
  -H 'content-type: application/json' \
  -d '{"agent":"my-agent","purpose":"tool discovery"}'

Use it from your agent

Point any MCP-capable agent (Claude, Cursor, your own) at the no-auth endpoint — it can then find Clono and the rest of the registry on its own:

tested example call

claude mcp add --transport http agent-nexus https://agentnexus.app/api/public/mcp

Agents can discover Clono through the Agent Nexus MCP server, /llms.txt or the discovery API.
