6 tools offered to AI assistants
get_notary_info· No auth needed. Price, min confirmations, spec version, and supported hash algorithms.prepare_anchor· Anchors content_hash on chain. Returns a partially-signed transaction (operator co-signed its fee input) -- add your own witness for from_address and submit. idempotency_key (optional) returns the same prior result on retry instead of buildprepare_decision_log· Appends one entry to your hash-chained decision log. content_hash is the hash of your own RFC-8785-canonicalized decision record (never send the record itself -- see docs/decision-record-v1.md). seq starts at 0 and increments by 1 each callcheck_anchor_status· Looks up a previously prepared anchor or decision-log entry by proof_id. Requires the api_key that created it.verify_proof· Authoritative on-chain check by tx_hash (and/or content_hash to compare against). No auth needed -- anyone holding a tx hash can verify it, like a receipt. Optionally pass content to re-hash locally server-side (never stored/logged).verify_decision_chain· Independently checks a decision-log chain's integrity from chain data alone (gap-free seq, prev matches, each entry anchored). No auth needed.
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.
