THE RISK

Why figma_delete_variables needs a policy

The tool explicitly deletes variables and states the action cannot be undone, making it irreversibly destructive. High severity because variables may be referenced throughout a Figma document, and deleting them could break styles, components, and bindings across the entire document.

From the tool's definition "Delete one or more variables from the document. Use with caution - this cannot be undone."

POLICY

How to control figma_delete_variables

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

policy.json

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

figma_delete_variables 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 Figma MCP Bridge — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
