Why crow_vikunja_delete_task needs a policy

This tool permanently removes data without the ability to recover it. The irreversible nature of task deletion in a project management system, where tasks represent work items that may have associated metadata, comments, or dependencies, makes this a destructive operation.

From the tool's definition Tool description states 'Delete a task from Vikunja (irreversible)' — the word 'Delete' combined with explicit '(irreversible)' designation indicates an action that cannot be undone.

POLICY

How to control crow_vikunja_delete_task

PolicyLayer is an MCP gateway — it sits between your AI agents and Crow, and nothing reaches the server without passing your rules. This is the rule we recommend for crow_vikunja_delete_task:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "crow_vikunja_delete_task"
  ]
}

crow_vikunja_delete_task disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register Crow — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
