Parameters from the server's own tool schema.
This tool retrieves and enumerates existing product sources—a read-only operation. The verb 'list' clearly denotes data retrieval without creating, modifying, deleting, or executing external operations. No financial or destructive actions are possible. Severity is low because querying product source metadata poses minimal risk even if misused by an agent.
From the tool's definition Tool name 'list_product_sources' and description 'List all product sources for a publisher' indicate a retrieval/query operation with no modification or side effects.
