Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

verify
verify_record
Checks whether a signed document, an agreement, a receipt or a Share proof is genuine, and what it says. It runs the same public check anyone can run at attest.datahubz.com/verify, with no account. It takes one of: an agreement ID (agr_...), the verification code printed on every signature stamp (ATT-XXXX-XXXX), a receipt ID (rcpt_...), a Share proof ID (azk_...), or a SHA-256 fingerprint (64 hex characters) of a file. For a signed agreement it returns its status, each signer's name and signing time, whether every passkey signature checks out, and its blockchain anchor on Horizen. A private agreement is reported as private: its parties verify it through zero-knowledge proofs instead. It takes a file's fingerprint, never the file itself: the SHA-256 can be computed on the person's device (for example shasum -a 256 file.pdf), or the file dropped on attest.datahubz.com/verify, where it is fingerprinted in the browser and never uploaded. Text people typed (titles, notes, names, claims) comes only in untrustedText fields, apart from Attest's own wording. Email addresses, wherever they appear, were typed by people too (a sender chooses the signers' addresses) and are unverified input.

Attest by DataHubz (verify only) — questions

Answers built from our own checks of this server.

What can Attest by DataHubz (verify only) do?
It exposes 1 tools, read directly from the server on our last check. Among them: verify_record. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README. How MCP servers expose tools in the first place →
Is Attest by DataHubz (verify only) working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 19 of 92 checks got a reply (20.7%), average response time 513 ms. The bar chart above shows every period we have measured.
The registry lists Attest by DataHubz (verify only) as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Attest by DataHubz (verify only)?
Copy the ready config from this page — we generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each with the file path that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Attest by DataHubz (verify only) need an API key?
No. Attest by DataHubz (verify only) completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 1 of them are readable on this page. This is what we observed, not what the docs claim.
How fast is Attest by DataHubz (verify only)?
It answers our handshake in 513 ms on average, which is faster than 22% of all working MCP servers we measure. That is on the slow side — worth knowing if the tool sits inside an interactive loop. The comparison comes from our own checks across the whole registry, every 15 minutes.
Is Attest by DataHubz (verify only) open source?
Yes — it is published under the MIT licence and 0 stars on GitHub. The source link is on this page, so you can read exactly what it does with your data before you connect it.
