Why get_card_item needs a policy

This tool retrieves data from a Miro board without creating, modifying, or deleting any content. It is a simple query operation that has no impact on the board state. The blast radius of misuse is minimal—an agent could only access information that already exists, with no ability to change or destroy data.

From the tool's definition Tool name 'get_card_item' and description 'Retrieves information for a specific card item on the current board' indicate a read-only operation with no side effects.

POLICY

How to control get_card_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 get_card_item:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_card_item": {}
  }
}

get_card_item is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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