Changes things 4Claude Code: ask
  • call_verifiedRelay a tools/call to a registered MCP service and notarize the exchange: request hash + response hash + outcome land in a tamper-evident receipt chain.No findings

    Why it is in this group

    • The name "call_verified" says "call": a word for a change.
    Description, as the server wrote it
    Relay a tools/call to a registered MCP service and notarize the exchange: request hash + response hash + outcome land in a tamper-evident receipt chain. Idempotent on call_id (a replay returns the original receipt and cached result — the downstream is never double-called). Failures are receipted evidence, not silence.
  • register_serviceRegister a third-party MCP server (https, public FQDN only) under Viridis Verified.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
    Register a third-party MCP server (https, public FQDN only) under Viridis Verified. Returns a content-addressed service_id; idempotent on (url, provider). fee_minor is the per-verified-call fee in cents.
  • service_statsCall counts, error counts, and accrued fees for one service.No findings

    Why it is in this group

    • The description's first verb is "call": a word for a change.

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.
