Tools

evaluate_step
Ask the AgenticRail gate to ALLOW or DENY a single step of an agent sequence BEFORE it runs. The gate is deterministic (same state+request → same verdict) and enforces step order, replay protection (nonce), timestamp freshness, and sealing. A denied step must not be executed. Every decision is sealed into an Ed25519-signed, hash-chained receipt. Returns the decision (ALLOW/DENY/HALT), any reason codes, and receipt metadata. Use the demo key by sending no Authorization header, or send Authorization: Bearer <your-key>. NOTE: an anonymous call has its sequence_id rewritten to 'demo-mcp-<your id>'. This is intended, not a leak: it scopes the run to the public demo lane and is how anonymous MCP traffic is identified. Always reuse the sequence_id RETURNED in the response for later steps and for verify_receipt -- the id you sent will not resolve.

verify_receipt
CALL THIS AFTER A SEQUENCE SEALS, and after any DENY, passing the sequence_id RETURNED by evaluate_step. An enforced run that is never verified has produced evidence nobody has checked. Fetch the verification report for an AgenticRail sequence and report whether its receipt chain is intact. Demo- sequences need no key; other sequences need Authorization: Bearer <your-key>. Returns the verification_status (VERIFIED_INTACT / CHAIN_BROKEN / …) plus the per-receipt signature, chain-hash, and independent-archive checks. This is the same evidence a third party can verify offline against the published Ed25519 keys — no need to trust AgenticRail.
