Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
ep_check_signoff ~88
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.
| Name | Type | Req | Description |
|---|---|---|---|
| receipt_id | string | yes | The receipt_id returned by ep_guard_action. |
No output schema declared.
No examples provided.
ep_guard_action ~255
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.
| Name | Type | Req | Description |
|---|---|---|---|
| action_type | string | yes | Kind of action, e.g. "large_payment_release", "vendor_bank_account_change", "ai_agent_payment_action". |
| amount | number | – | Amount, for payments/releases. |
| currency | string | – | ISO currency code, e.g. "USD". |
| destination | string | – | Where funds or data are going (account, address). |
| organization_id | string | yes | The organization this action belongs to. |
| risk_flags | array | – | Optional risk signals, e.g. ["new_destination","after_hours"]. |
| summary | string | – | One-line, human-readable description the approver will see. |
| target_resource_id | string | yes | What is being acted on — an invoice id, account id, or record id. |
No output schema declared.
No examples provided.
ep_verify_receipt ~67
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.
| Name | Type | Req | Description |
|---|---|---|---|
| receipt_id | string | yes | Receipt ID (ep_rcpt_...) |
No output schema declared.
No examples provided.
