Why nasa_apod is rated Low
This tool retrieves publicly available astronomy imagery from NASA's API. It performs a read-only query operation with no capability to modify, execute, delete, or commit financial transactions. The data retrieved is static and non-sensitive. Severity is low due to minimal blast radius if misused by an AI agent—at worst, excessive requests might hit rate limits.
From the tool's definition Tool name 'nasa_apod' and description 'Get NASA Astronomy Picture of the Day' indicate a retrieval operation with no side effects. The verb 'Get' confirms data is being queried/fetched.

The rule that runs nasa_apod safely

nasa_apod is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
The button opens the PolicyLayer dashboard: create your workspace, connect UnClick, apply this rule, and every nasa_apod call is checked against it from then on.
