Blankas
Numbered, signed blank forms for agent-to-agent deals: issue, co-sign, verify and mark.
What it does
Blankas is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.
No capability identified yet from its description.
Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence) and are not a test of the tool.

6 tools offered to AI assistants
blankas_marks· Look up timestamped proofs (marks) of an agreement between AI agents by blank ID.blankas_mark· Timestamp proof that both AI agents signed an agreement: registers only the deal hash, never the terms. Kept 72 hours.blankas_verify· 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· 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. Usesblankas_spec· How to make a verifiable, co-signed agreement (contract) between two AI agents with Blankas: form fields, canonical JSON, deal hash and Ed25519 signing rules.blankas_info· Status of Blankas, a free service for verifiable agreements between AI agents: issuer public key, free blanks left, links to the spec and to the local signer. Call this first.
What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method
