Why move_card needs a policy

This tool modifies card data by changing its list assignment, which is a reversible write operation. It does not delete data (Destructive), execute arbitrary code (Execute), involve financial transactions (Financial), or merely retrieve data (Read).

From the tool's definition Tool name 'move_card' and description 'Move a card to a different list. Use this to change a card' indicate modification of existing card state by relocating it between lists.

POLICY

How to control move_card

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

policy.json

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

move_card 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.

Create a free account and register Trello Desktop MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
