Can't be undone 1Claude Code: ask
  • payment_preflightFast pre-payment consistency guard for AI agents.No findings

    Why it is in this group

    • The name "payment_preflight" says "payment": a word that usually means money moves, which cannot be taken back.
    Description, as the server wrote it
    Fast pre-payment consistency guard for AI agents. Checks HTTPS destination, EVM payTo format, Base network, amount validity, and detects recipient/network/price changes against caller expectations. Returns allow/review/block. Use vendor_preflight for deep KYB.
Changes things 1Claude Code: ask
  • vendor_preflightVerify vendor identity before paying: KYB, supplier risk and counterparty checks for AI agents.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 vendor identity before paying: KYB, supplier risk and counterparty checks for AI agents. Returns allow/review/block with legal-entity evidence, potential sanctions signals, RDAP domain evidence and company-domain consistency. Payment safety decision support via x402; not legal or transaction approval.

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.
