Parameters from the server's own tool schema.
The mapbox_geocode_forward tool is a read-only operation that queries the Mapbox geocoding API to retrieve coordinates for a given address or place name. It retrieves data without creating, modifying, deleting, or executing any operations with side effects. The blast radius of misuse is minimal - an attacker could enumerate addresses or perform bulk geocoding queries, but no data is at risk of loss or financial harm.
From the tool's definition Tool description states 'Convert an address or place name to coordinates' - this is a query operation that retrieves geographical data with no side effects. It performs a lookup/transformation of input to output data.
