WHAT IT DOES

What tasks_delete does on Vikunja

AI agents call tasks_delete to permanently remove resources in Vikunja, typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.

RISK

Why tasks_delete is rated Critical

Task deletion is irreversible and removes data permanently. While the blast radius is limited to a single task (not organization-wide), the destructive nature of the operation and the potential for accidental deletion of important work items justifies 'high' severity. Destructive is the most severe applicable category here, superseding Write or Execute classifications.

From the tool's definition Tool name is 'tasks_delete' with description 'Delete a task'. The verb 'delete' combined with the irreversible nature of removing a task from a task management system indicates this is a destructive operation that cannot be undone.

RECOMMENDED RULE

The rule that runs tasks_delete safely

PolicyLayer is an MCP gateway: it sits between your AI agents and Vikunja, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For tasks_delete, this is the rule to start with:

tasks_delete Hidden

tasks_delete is removed from the agent's tool list entirely, so the agent never calls it. The rest of the server keeps working.
