Why create_sticky_note_item needs a policy

This tool creates new data (a sticky note) on a Miro board, which is a reversible action characteristic of Write category. It has low severity because sticky notes are typically low-impact collaborative artifacts; misuse would result in minor board clutter rather than data loss or financial harm. The confidence is high because the tool's purpose is unambiguous from both its name and the server's stated functionality.

From the tool's definition Tool adds a sticky note item to the board, which creates new content on the board reversibly. The server description confirms this is part of operations like 'creating items' and 'updating positions'.

POLICY

How to control create_sticky_note_item

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 create_sticky_note_item:

policy.json

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

create_sticky_note_item 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.
