WHAT IT DOES

What drive_folder_share_with_account does on TrekMail MCP Server

AI agents use drive_folder_share_with_account 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_share_with_account is rated Medium

This is a Write operation because it creates and modifies resource sharing relationships and metadata (folder visibility, quota assignments) across the account infrastructure. While the migration is atomic and the operation is idempotent (calling it again returns the folder unchanged), it irreversibly changes who can access the data and how quotas are tracked.

From the tool's definition The tool description states it makes a folder 'visible to every mailbox in the account' and performs a migration of folders and files 'in one transaction' with 'quota counters move from mailbox to account.' This modifies data ownership and accessibility,…

FAQ

Questions about drive_folder_share_with_account

What does the drive_folder_share_with_account tool do? +

Make this folder visible to every mailbox in the account. If the folder lives in a mailbox-personal Drive, the entire subtree (folders + files) is migrated to account-drive in one transaction; quota counters move from mailbox to account. Restrictions: folder must be top-level (parent_id=null); subtree must contain ≤ 1000 files; account pool must have room for the migrated bytes. Idempotent — calling on an already-shared folder returns it unchanged. It is categorised as a Write tool in the TrekMail MCP Server MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.
