Why inspect_screen_structure needs a policy

This tool retrieves and examines Figma design data to provide structural information about screens. It performs no modifications, deletions, code execution, or financial operations. The action is purely informational—inspecting and reporting on existing design data.

From the tool's definition Tool name 'inspect_screen_structure' and description 'Get a quick overview of screen structure, sections, and navigation elements' indicate data retrieval only. The verb 'inspect' and 'get overview' are queries without side effects.

POLICY

How to control inspect_screen_structure

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

policy.json

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

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