What app_response does on Goose App Maker MCP

WHY IT NEEDS A POLICY

Why app_response needs a policy

Without a description, confidence is reduced. The tool name suggests it responds to or modifies application responses. Given the context of a web app management server, this is most consistent with Write (modifying app responses) rather than Read (which would be 'app_get_response'). Not Destructive or Execute based on naming alone.

From the tool's definition Tool name 'app_response' with empty description; sibling tools include 'app_create', 'app_delete', 'app_serve', suggesting this server manages web application lifecycle. 'app_response' most likely writes or modifies response data for applications.
