THE RISK

Why todoist_tasks needs a policy

While the tool includes Read (query tasks) and Write (create, update) operations, it also explicitly supports delete operations on tasks, which is irreversible. Delete/destroy operations take precedence in the severity hierarchy over reversible modifications. The high severity reflects that an AI agent with this tool could permanently remove user task data without recovery.

From the tool's definition Tool description explicitly states "create, read, update, delete" and "full CRUD operations" including delete capability. The delete operation on tasks is irreversible data destruction.

POLICY

How to control todoist_tasks

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

policy.json

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

todoist_tasks 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 Mcp Todoist — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
