What disconnect_m365_account does on Local
AI agents use disconnect_m365_account to create or update resources in Local, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Local environment.
Why disconnect_m365_account is rated Medium
This tool reverses a configuration state (disconnects an account and deletes tokens), which is a modification action. It differs from Destructive because the action is standard account management and reversible by reconnecting, rather than deletion of user data. The severity is medium because misuse could require the user to re-authenticate, but does not directly access, modify, or destroy user data itself.
From the tool's definition Tool explicitly performs 'Disconnect your Microsoft 365 account and remove stored tokens,' which modifies the stored authentication state by removing credentials.
