Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • email_check unknown never probed

    Check one email address: syntax, mail route, MX hosts, disposable provider, role account, typo suggestion, catch-all estimate, and a verdict with a confidence between 0 and 1. Never claims a mailbox exists without evidence; the honest default for a routable address is "unknown". 0.001 USDC per call over x402.

      "type": "boolean",
      "default": false,
      "description": "Ask for an optional SMTP probe. Off by default, heavily throttled, one attempt per target and never retried. Without it the verdict of a routable address stays \"unknown\"."
    }
  }
}

  • email_check_batch unknown never probed

    Check up to 100 email addresses in one paid call. Billed 0.0006 USDC per address; the 402 quotes the exact amount for the addresses in the request. One DNS lookup per distinct domain, cached 24 hours.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ how we know
card completeness
60%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
