WHAT IT DOES

What delete_form_share does on AIquila — Nextcloud MCP Server

AI agents call delete_form_share to permanently remove resources in AIquila — Nextcloud MCP Server, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why delete_form_share is rated Critical

The tool irreversibly revokes/deletes a form share, removing another user's access to a shared form. This is a destructive action because: (1) it permanently removes an access grant, (2) the revoked user loses their ability to view/interact with the shared form unless re-granted, and (3) there is no automatic undo mechanism.

From the tool's definition Tool name contains 'delete' and description states 'Revoke a form share' - this action removes access permissions permanently and cannot be easily undone by the user who lost access.
