RISK

Why update_location_custom_value is rated Medium

This tool creates or modifies data (a custom value associated with a location) in a reversible manner. It aligns with the Write category: creates or modifies data reversibly. Severity is medium because unauthorized updates to location configuration could affect business operations or customer data integrity, but the change is reversible via another update operation.

From the tool's definition Tool name and description: 'update_location_custom_value' with 'Update an existing custom value' indicates reversible modification of data fields.
