THE RISK

Why move_tasks_to_parent needs a policy

This tool creates or modifies data (task parent-child relationships) reversibly. While it reorganizes task structure, the changes are not destructive—tasks remain intact and the operation can be undone by moving tasks back or reassigning parents. The blast radius is moderate: incorrect execution could reorganize workflows and require manual cleanup, but no data is lost or financial impact occurs.

From the tool's definition The tool "move_tasks_to_parent" modifies the hierarchical structure and parent assignment of existing tasks, stated as "creates a hierarchical relationship where the moved tasks become children of the specified parent task" and "Returns the updated task…

POLICY

How to control move_tasks_to_parent

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "move_tasks_to_parent": {
      "limits": [
        {
          "counter": "move_tasks_to_parent_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

move_tasks_to_parent stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
