WHAT IT DOES

What delete_contact does on AIquila — Nextcloud MCP Server

AI agents call delete_contact 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_contact is rated Critical

The tool permanently removes contact data from the address book without reversibility. This is irreversible deletion, making it Destructive rather than Write. Severity is high because loss of contact information can disrupt communications and workflows, though the blast radius is typically limited to a single contact entry unless the tool is chained across multiple contacts.

From the tool's definition Tool name 'delete_contact' combined with description stating 'Delete a contact from a Nextcloud address book by UID. This action is irreversible.' explicitly indicates permanent removal of data with no undo capability.
