  • broker.introspect-grantFree

    Validates a grant token seal, reports active/revoked/expired state, and records introspection to the ledger.

  • broker.register-credentialFree

    Registers an opaque vault handle/reference only; plaintext secret fields are rejected and never ledgered.

    Asks the canonical Policy Engine for an ALLOW decision before issuing a short-lived HMAC-sealed grant bound to credential, mandate, agent, scope, and expiry.

  • broker.revoke-grantFree

    Revokes a broker grant by id and records the revocation to the ledger.

  • broker.useFree

    Redeems a sealed grant for the bound acting agent and executes the bound action through the Gateway and Policy Engine; does not expose plaintext secrets.

  • mandate.authorize-actionwrite actionFree

    Submits an action through the Gateway and canonical Policy Engine; returns ALLOW, DENY, or REQUIRE_APPROVAL with ledger proof.

  • mandate.delegatewrite actionFree

    Creates a child mandate only when it is a no-escalation subset of the parent mandate.

  • mandate.discoverFree

    Returns this self-describing tool manifest.

  • mandate.mintwrite actionFree

  • mandate.verify-proofFree

    Records a proof payload hash and appends proof evidence to the hash-chained ledger.
