Tools & Capabilities Breakdown

Emilia Protocol Tools (3)

ep_guard_action

Request authorization before an irreversible action: payments, wire transfers, fund releases, deletions, record or account changes, or sending messages with real-world effect. Submits the exact action for policy evaluation and human authorization. This MCP tool does not itself sit at the executor choke point: even after approval, the executor MUST match the returned action_hash and atomically consume the receipt before effect. If BLOCKED, poll ep_check_signoff with the receipt_id.

ep_check_signoff

Poll a pending authorization after ep_guard_action returns BLOCKED. Pass the receipt_id. Returns PENDING, APPROVED_PENDING_CONSUME, CONSUMED, or DENIED. Approval alone is not permission to execute: the executor must match action_hash and atomically consume the receipt at its own choke point.

ep_verify_receipt

Ask the configured EMILIA service to verify a stored trust receipt and report its hash and anchor status. Read-only, but not an offline verifier: the result is the service response for the supplied receipt_id.
