Why update_item_position_or_parent needs a policy

This tool modifies item metadata (position and parent references) on a Miro board, which is characteristic of a Write operation—it changes state but does not delete, execute code, or cause financial impact. The changes are reversible (items can be repositioned again or reparented).

From the tool's definition Tool description states it 'Updates the position or parent of a specific item on the current board.' The verb 'Updates' combined with modifying positional/structural attributes indicates reversible data modification.

POLICY

How to control update_item_position_or_parent

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

policy.json

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

update_item_position_or_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.
