  • nomos_crossborder_preflightCross-border regulatory preflight for agent data flows.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.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Cross-border regulatory preflight for agent data flows. Checks jurisdiction pair (EU, JP, IN, KR, SG, CN, BR, NG, ZA, MX) and data category against a local policy matrix. Returns verdict: ALLOW / ALLOW_PUBLIC_SIGNAL_ONLY / REVIEW / BLOCK (or ERROR for unsupported input), plus blocked_fields, sccs_required, risk_level, matrix_coverage and evidence_hash. Local lookup only — no network access, no legal advice.

    • Nothing in its name or description says what it does, so it is counted as a write.
    • The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
    Description, as the server wrote it
    Look up a NOMOS operation record by its exact SHA-256 receipt hash in the local handshake audit log. Requires a full 64-hex hash, optionally 'sha256:'-prefixed; matching is exact against the stored receipt_hash/entry_hash fields. This is a record lookup, NOT cryptographic signature verification — the response always reports cryptographically_verified: false.

    Description, as the server wrote it
    Read-only view of the most recent local daily scan artifact covering 6 regions: Japan, Singapore/China, India, Korea, Brazil/LatAm, Africa. Returns MCP-ready companies, funded entities, compliance signals. The artifact is written once per day by a separate scanner job; this tool performs no live scanning and no network requests.

    Why it is in this group

    • The description's first verb is "search": a word for reading.
    Description, as the server wrote it
    Search a small static curated catalog of OracleNet MCP tools by keyword and category. Returns tool names, endpoints, protocol support. Local data only — does not probe, crawl or contact any network endpoint.

    Why it is in this group

    • The description's first verb is "get": a word for reading.
    Description, as the server wrote it
    Get a stateless, unsigned, informational x402 price quote for NOMOS services. Tier 1: $0.02 simple verdict | Tier 2: $0.05 verdict + evidence | Tier 3: $0.10 full packet. Returns payTo address, network (Base mainnet), amount in USDC atomic units, and a deterministic quote digest (not a signature). No payment is initiated and nothing is signed, persisted or reserved; expiry is informational only.

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.
