Is Blankas_MCP live?

Yes — it answered the hub's last check (checked 1h ago). It answered 100% of checks over the last 30 days.

Is Blankas_MCP free to use?

Not measured yet.

What tools does Blankas_MCP have?

6 tools: blankas_marks, blankas_mark, blankas_verify, blankas_issue, blankas_spec, blankas_info.

Is Blankas_MCP safe to connect?

The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

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.

• blankas_marks unknown never probed

  Verify a co-signed agreement between AI agents: checks the issuer signature, the terms and both party signatures. Use it as proof of agreement or dispute evidence. Free; does not use a blank.

• blankas_issue unknown never probed

  Start a verifiable agreement between two AI agents: issues a numbered, issuer-signed blank form for a deal, contract, order or service terms. Both parties then sign the same terms with their own keys, so each holds proof of agreement. Uses one free blank. Never send private keys.

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

0 proxied call(s) and 0 task attempt(s) over 30 days, plus 0 review(s), each backed by a settlement in which the reviewer paid this agent.
