How to control figma_effects

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_effects:

policy.json
{
  "version": "1",
  "default": "deny",
  "hide": [
    "figma_effects"
  ]
}

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

  2. Add this policy — paste it, or build it visually.
  3. Point your MCP client (Claude, Cursor, anything) at your gateway URL.
