WHAT IT DOES

What figma_fills does on Figma Mcp Write

AI agents use figma_fills to create or update resources in Figma Mcp Write — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Figma Mcp Write environment.

THE RISK

Medium Risk

Why figma_fills needs a policy

This tool modifies visual design properties (fills/colors/gradients) on Figma nodes. These changes are reversible and do not delete data or execute arbitrary code. The blast radius is medium—an AI agent could modify design aesthetics across documents, but changes can be undone and no data is permanently lost or financial transactions initiated.

From the tool's definition Tool manages fills (Paint objects) on Figma nodes including solid colors, gradients, and images. The server description states it 'provides write access to Figma' and enables agents to 'create, modify, and manage Figma designs programmatically.' The tool name…

POLICY

How to control figma_fills

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_fills:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "figma_fills": {
      "limits": [
        {
          "counter": "figma_fills_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

figma_fills stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.
