THE RISK

Low Risk

Why get_image_bytes needs a policy

This tool retrieves/downloads image data from Figma and persists it locally. While it involves file I/O, it is purely a read operation on Figma's side with no side effects to the design file itself. The action is data retrieval (download), which is characteristic of the Read category. Severity is low because unauthorized image export poses minimal risk compared to design modification or data destruction.

From the tool's definition Tool name 'get_image_bytes' and description 'Download image from Figma and save to local file' indicate retrieval and export of data without modification of Figma content.

POLICY

How to control get_image_bytes

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

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "get_image_bytes": {}
  }
}

get_image_bytes is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Create a free account and register Claude Talk to Figma MCP — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
