## Why lookup_execution is rated Low

Retrieves historical execution data without modifying state or triggering new operations.

From the tool's own definition: "Read-only lookup for a prior Call by its exact idempotency key"

## Use case

AI agents call lookup_execution to retrieve information from Qverisai without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

## Recommended policy (PolicyLayer)

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

```json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "lookup_execution": {}
  }
}
```
