## Why annul_sp_request is rated Critical

Cancelling a pending stability pool request is an irreversible action that terminates an in-flight financial operation on-chain. While it returns an unsigned transaction (requiring client signing), the intent is to permanently cancel/annul a request. This falls under Destructive as the cancellation of the pending request cannot be undone once submitted.

From the tool's own definition: "Cancel a pending stability pool request"

## Use case

AI agents call annul_sp_request to permanently remove resources in Indigo Protocol MCP, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

## Recommended policy (PolicyLayer)

Verdict: **Hidden**. Enforced by the PolicyLayer MCP gateway (https://policylayer.com/mcp-gateway) before a call reaches Indigo Protocol MCP:

```json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "annul_sp_request"
  ]
}
```
