What it does

ZKStamp Proof-100 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). None of this is a test of the tool.

3 tools offered to AI assistants

timestamp_fingerprint · Write a SHA-256 fingerprint privately (shielded, zk-SNARKs) on the BitcoinZ blockchain. Returns the transaction ID and a viewing key for this one proof. Keep both: together they let anyone you choose verify this proof, and nothing else. Use
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 p
check_balance · Show how many Proof-100 proofs are left and the BTCZ deposit address for buying more.

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

Is this your server? Monitoring Pro: a check every 30 minutes and an email within the hour when it stops answering. Launch offer: $39.99 once, for life.
