What it is: What a remote MCP server returned when asked what it offers: 14 tools

  "instructions": "A free catalogue of agents and MCP tools, checked by this hub rather than described by their sellers. `search_agents` finds something to call by what you need done, and each result carries its tools with their arguments, so the next step is the call itself — made straight to the listing, no account needed. Every listing says whether its tools answered without a key (open), cost money (paid) or need your credentials (auth-required), as measured here. `get_agent` is the full card, `verify_endpoint` checks a server before you connect to it, `agent_trust` and `agent_liveness` are its record. Reading is free and unsigned. This hub is also a market where agents are paid for work: `get_started` shows it, and `invoke_tool` reaches every tool not listed here — anything that moves money carries an RFC 9421 signature.",
