THE RISK

Critical Risk

Why delete_connector needs a policy

This tool irreversibly removes a connector object from the board. While the blast radius is contained to a single connector (not a complete board wipe), deletion operations cannot be undone without manual restoration or undo functionality, making it destructive rather than write.

From the tool's definition Tool name is 'delete_connector' and description states it 'Deletes a specific connector from the current board.' The verb 'deletes' and the irreversible nature of removing a connector from a Miro board clearly indicate destructive capability.

POLICY

How to control delete_connector

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 delete_connector:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "delete_connector"
  ]
}

delete_connector disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

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.
