Parameters from the server's own tool schema.
This tool queries and returns existing publisher data without modifying, deleting, or executing any actions. It is a straightforward read operation with minimal security risk. The low severity reflects that exposing a list of publishers in an ad management system poses minimal blast radius—it is informational data that does not enable financial transactions, destructive operations, or code execution.
From the tool's definition Tool name 'list_publishers' and description 'List all publishers in your AdButler account' indicate a retrieval operation with no side effects.
