Changes things 7Claude Code: ask
  • bind_identityBind a fleet DID to an ERC-8004 identity.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
    Bind a fleet DID to an ERC-8004 identity. Produces an order-independent, content-addressed (unsigned) binding attestation.
  • export_attestationExport the agent's current trust score as an UNSIGNED ERC-8004 Validation Registry-shaped payload, content-addressed and ready for YOUR OWN signer to anchor on-chain.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
    Export the agent's current trust score as an UNSIGNED ERC-8004 Validation Registry-shaped payload, content-addressed and ready for YOUR OWN signer to anchor on-chain.

    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
    Build UNSIGNED ERC-8004 Validation Registry validationResponse args from an Outcome Receipt (ORC v0.1): responseHash = receipt commitment, tag "orc/0.1", response 100 only if the bridge re-verifies the receipt AND your replay succeeded. Sign and submit with your own signer; this bridge holds no keys and writes to no chain.
  • import_feedbackImport ERC-8004 Reputation Registry feedback records for an agent.No findings

    Why it is in this group

    • The name "import_feedback" says "import": a word for a change.
    Description, as the server wrote it
    Import ERC-8004 Reputation Registry feedback records for an agent. Each item: {value: bool|0..1, at: ISO-8601, source?, weight?, feedback_id?}. Idempotent per feedback_id.
  • import_registrationImport an ERC-8004 Identity Registry record (chain_id + ERC-721 token_id + agentURI + owner).No findings

    Why it is in this group

    • The name "import_registration" says "import": a word for a change.
    Description, as the server wrote it
    Import an ERC-8004 Identity Registry record (chain_id + ERC-721 token_id + agentURI + owner). Idempotent: re-import updates in place. Returns the canonical record with its deterministic bridge DID (did:viridis:erc8004:<chain>:<token>).

    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
    Decay-weighted trust score in [0,1] + tier over the agent's imported ERC-8004 feedback — recent behavior outweighs old; no feedback scores a neutral 0.5 prior (no blind trust, no unfair zero).
  • verify_attestationRecompute a payload's content hash and report whether it is intact.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
    Recompute a payload's content hash and report whether it is intact.

  • describe_agentReturn the bridge's capabilities and input contract.No findings

    Why it is in this group

    • The name "describe_agent" says "describe": a word for reading.
    Description, as the server wrote it
    Return the bridge's capabilities and input contract.
  • list_registrationsList all imported ERC-8004 registrations.No findings

    Why it is in this group

    • The name "list_registrations" says "list": a word for reading.
    Description, as the server wrote it
    List all imported ERC-8004 registrations.
  • resolve_agentResolve an imported ERC-8004 registration by bridge DID or by (chain_id, token_id).No findings

    Why it is in this group

    • The name "resolve_agent" says "resolve": a word for reading.
    Description, as the server wrote it
    Resolve an imported ERC-8004 registration by bridge DID or by (chain_id, token_id).

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.
