Read https://toolcargo.com/agents.txt, then find the MCP servers I need and help me connect them. Ask me what I want to do first.

Or add https://toolcargo.com/mcp as a Streamable HTTP MCP server. Discovery is free and needs no account.

Compare task fit, publisher, permissions and a small acceptance test with the MCP server selection guide.
