  • issue_receiptMint a verifiable provenance receipt for an autonomous-agent action.No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Mint a verifiable provenance receipt for an autonomous-agent action. Returns a signed (ed25519), content-hashed (SHA-256), server-timestamped receipt that is hash-chained to this agent's prior receipts (tamper-evident audit trail). Pass the raw inputs/outputs (we hash them — raw data is never stored) OR pre-computed sha256 hashes. Use for compliance, audit trails, and dispute resolution of agentic actions. PAID: $0.01 USDC/call via x402.
  • verify_receiptVerify a receipt by id (or by passing the full receipt object).No findings

    Why it is in this group

    • Nothing in its name or description says what it does, so it is counted as a write.
    Description, as the server wrote it
    Verify a receipt by id (or by passing the full receipt object). Recomputes the content hash, confirms the id commits to the body, and checks the ed25519 signature. Returns the verification checks plus the provenance record (action, agent, input/output hashes, timestamp, chain position). FREE.
Only reads 1Claude Code: allow
  • list_receiptsList the receipt hash-chain for an agent_id, newest first (id, action, timestamp, sequence, hashes, verifyUrl).No findings

    Why it is in this group

    • The name "list_receipts" says "list": a word for reading.
    Description, as the server wrote it
    List the receipt hash-chain for an agent_id, newest first (id, action, timestamp, sequence, hashes, verifyUrl). Use to audit everything a given agent has attested. FREE.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
