THE RISK

Critical Risk

Why figma_styles needs a policy

The tool explicitly includes 'delete' as one of its operations, which is irreversible. Since the most severe applicable category takes precedence, and deletion of styles cannot be undone, this classifies as Destructive. Severity is medium as misuse would affect design styles within a Figma project but is limited in blast radius compared to broader destructive operations.

From the tool's definition Create, update, list, apply, delete, get, and duplicate paint, text, effect, and grid styles

POLICY

How to control figma_styles

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

policy.json

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

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