WHAT IT DOES

What drive_folder_stop_sharing does on TrekMail MCP Server

AI agents use drive_folder_stop_sharing to create or update resources in TrekMail MCP Server, usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your TrekMail MCP Server environment.

RISK

Why drive_folder_stop_sharing is rated Medium

This tool modifies the sharing state of a folder (reversibly changing is_shared to false). The folder is not deleted — it remains in the account-drive as a private folder. Since data is not destroyed and the action could be reversed by re-enabling sharing, this is a Write operation.

From the tool's definition Flip is_shared back to false on a shared folder... other mailboxes lose visibility, the dashboard owner keeps it as a private account-drive folder.
