Capabilities

What this server is able to do. For an MCP server this is often the job itself — a terminal server runs commands because that is what it is for. Listed so you know what you are plugging in, not as an accusation.

Runs an external command server/HealthCheck.py:25, zcheck/ZCheck.py:19, server/Proof100Core.py:45

    r = subprocess.run(CLI + list(a), capture_output=True, text=True, timeout=60)

Is this your server and something here is wrong? Tell us — corrections are free and do not require a plan.

This code can reach further than it looks

We found places where it runs commands, builds paths or queries from values it is given. None of that is a flaw by itself — it becomes one when the code changes, and code changes quietly between releases. We re-read it on every one.

Available tools 3

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

timestamp

timestamp_fingerprint

Create a private, dated proof that a file or data existed, without sending the data. Use this when you already have the SHA-256 fingerprint (hash) of a file; for a short text, use timestamp_text instead. Compute the hash locally over the exact bytes (for example: sha256sum MyFile.pdf) and pass the 64-character hex string. The fingerprint is written into the encrypted memo of a shielded (zk-SNARK) BitcoinZ transaction, sent to a new address made for this proof only; the block timestamp dates it. Takes about 10 to 60 seconds and uses 1 proof from the account (requires the account key in the Authorization header). Returns ok, txid, viewing_key, explorer link and proofs_left. Tell the user to keep the txid and viewing_key: together they let anyone verify this one proof with ZCheck, and reveal nothing else. On error (invalid fingerprint, invalid key, no proofs left, send failed) no proof is used.

timestamp_text

Compute the SHA-256 fingerprint of a short text on the Proof-100 server (the text is not stored), then write that fingerprint privately on the BitcoinZ blockchain. Returns the fingerprint, the transaction ID and a viewing key for this one proof. Keep the viewing key: with the txid it reveals this proof only. Uses 1 proof.

balance

check_balance

Show how many Proof-100 proofs are left and the two BTCZ deposit addresses for buying more: deposit_address (shielded zs, fully private) and t_deposit_address (transparent, for exchanges and t-only wallets like Coinomi; the payment is visible on the blockchain, the proofs stay shielded). 500,000 BTCZ to either (or both together) = 100 proofs after 2 confirmations.

ZKStamp Proof-100 — questions

Answers built from our own checks of this server.

What can ZKStamp Proof-100 do?

It exposes 3 tools, read directly from the server on our last check. Among them: check_balance, timestamp_fingerprint, timestamp_text. 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 ZKStamp Proof-100 working right now?

We send a real MCP handshake every 15 minutes. Over the last 24 hours 72 of 92 checks got a reply (78.3%), average response time 122 ms. The bar chart above shows every period we have measured.

How do I connect ZKStamp Proof-100?

Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.

Does ZKStamp Proof-100 need an API key?

No. ZKStamp Proof-100 completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 3 of them are readable on this page. This is what we observed, not what the docs claim.

How fast is ZKStamp Proof-100?

It answers our handshake in 122 ms on average, which is faster than 88% of all working MCP servers we measure. That puts it in the quick quarter of the ecosystem. The comparison comes from our own checks across the whole registry, every 15 minutes.

Is ZKStamp Proof-100 open source?

The code is open source: it is published under the MIT licence, written in Python, 0 stars on GitHub and 1 open issue. The licence covers the code in the repository, not the hosted service at proof.zketernity.app, which runs on its operator's own terms.
