WHAT IT DOES

What bbs_auto_learn_namespace does on Mcp Bbs

WHY IT NEEDS A POLICY

Why bbs_auto_learn_namespace needs a policy

This tool modifies a configuration setting — the namespace/folder used for auto-learning data. It creates or updates a configuration value reversibly, making it a Write operation. The blast radius is low since it only affects which namespace is used for storing learned BBS navigation data, not any external system or irreversible data.

From the tool's definition Set the auto-learn namespace (game folder name) or clear to use shared
