Google Drive: Manage sharing and permissions — MCP tool

Google Drive MCP tool: Lists, grants, changes and revokes access to a file — users, groups, domains or anyone with the link.

Technical name: manage_permissions

What task it solves

I want to control who can access a file.

One tool for the whole sharing lifecycle: action=list shows the grants, share adds one, update changes a role, remove revokes it.

When to use it

Use it to share a file with a teammate, open link access, audit who can see a document, downgrade or revoke access, or transfer ownership.

What to provide

  • file_id — required; action — required: list, share, update or remove.
  • share: role (reader/commenter/writer/fileOrganizer/organizer/owner) + type (user/group/domain/anyone), with email_address for user/group, domain for domain, allow_file_discovery for domain/anyone; optional send_notification_email and email_message; transfer_ownership=true with role=owner.
  • update/remove: permission_id from action=list (+ role, optional expiration_time for update).

What it returns

The permission objects: id, type, role, emailAddress/domain, displayName, expirationTime, pendingOwner.

What changes in Google Drive

Access changes take effect immediately for real people. remove revokes access on the spot; removing your own access to someone else's file cannot be undone from your side — that is why the whole tool is flagged destructive.

Example request

Share the roadmap doc in Google Drive with anna@example.com as a commenter, without the notification email.

Errors and limitations

fileOrganizer/organizer exist only on shared drives. Ownership transfer between personal accounts only invites the new owner (pendingOwner) until they accept, and the notification email cannot be suppressed for it. role=owner/organizer grants full control including permanent deletion — prefer writer or less.
