Tools (5)

Read from the source code; the running server may differ. Descriptions are the server’s own words; hidden characters are shown as [U+…].

  • sentinel_audit_transaction

    Run a full 9-check security audit on an agent payment transaction. Checks: token integrity, budget enforcement, merchant allowlist, category restriction, expiry, rate limit, amount mismatch, replay attack, and revocation evasion. Returns PASS/BLOCKED with per-check detail and a tamper-evident SHA-256 audit hash.

  • sentinel_clear_nonce

    Remove a nonce from the used-nonces store. Use only for legitimate refunds/retries — this re-enables a previously seen transaction.

  • sentinel_revoke_token

    Revoke a token permanently. Persisted to ~/.sentinel/revoked_tokens.json. Any future audit with this token_id will be BLOCKED.

  • sentinel_threat_model

    Simulate a red-team attack. Returns the attack vector, severity, defence mechanism, and detection method.

  • sentinel_verify_chain

    Verify SHA-256 audit chain integrity. Detects tampering in a sequence of audit logs.
