Why move_task_between_notes needs a policy

This tool modifies the state of tasks by changing their note association, which is a write operation. It is reversible (tasks can be moved again), so it does not qualify as Destructive. The blast radius is low because task relocation within a knowledge management system has minimal downstream impact compared to data deletion or code execution. No external systems, finances, or irreversible changes are involved.

From the tool's definition Tool name 'move_task_between_notes' and description 'Relocate task to different note' indicate modification of task metadata/location. This is a reversible data operation—tasks can be moved back.

POLICY

How to control move_task_between_notes

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

policy.json

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

move_task_between_notes 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.
