WHY IT NEEDS A POLICY

Why update_profile needs a policy

This tool modifies (updates) MCP profiles, which are configuration objects. While not irreversible like delete_profile (Destructive), updating profiles could alter active server configurations and system behavior. The empty description lowers confidence slightly, but the name and context of a profile management system clearly indicate a Write operation that changes configuration state.

From the tool's definition Tool name 'update_profile' and context of profile management system indicates modification of existing configuration data. The sibling tools 'create_profile' and 'delete_profile' confirm this server handles profile lifecycle operations.
