WHAT IT DOES

There are no data modifications, deletions, code execution, or financial transactions. The blast radius of misuse is minimal—an agent could only return unwanted or excessive lists of location data, which causes no harm.

From the tool's definition Tool name 'openaq-list-locations' and description 'List OpenAQ air-quality monitoring locations' indicate retrieval of data. The 'Filter by coordinates' clause confirms this is a query operation with no side effects.
