Changes things 2Claude Code: ask
  • issue_receiptAnchor a SHA-256 digest of delivered content plus the x402 settlement reference on Solana.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
    Anchor a SHA-256 digest of delivered content plus the x402 settlement reference on Solana. Returns a permanent, publicly verifiable receipt (poll until outcome === "settled"). Costs 0.001 USDC via x402; if x402_payment_signature is omitted, returns the payment challenge instead (pay 0.001 USDC to the service address, then call again with the payment tx signature).
  • verify_receiptVerify an AgentToll receipt against live Solana state: PDA owner must be the AgentToll program and the stored digest must match the receipt.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 an AgentToll receipt against live Solana state: PDA owner must be the AgentToll program and the stored digest must match the receipt. Look up by receipt_id, or by x402_payment_ref (always works — the receipt lives on-chain). Read-only, no cost.
Only reads 1Claude Code: allow
  • get_receiptFetch full receipt details: digests, checks, outcome, amount, buyer, seller, timestamp, PDA.No findings

    Why it is in this group

    • The name "get_receipt" says "get": a word for reading.
    Description, as the server wrote it
    Fetch full receipt details: digests, checks, outcome, amount, buyer, seller, timestamp, PDA. Look up by receipt_id, or by x402_payment_ref (always works — the receipt lives on-chain). Read-only, no cost.

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.
