Why export_flutter_assets needs a policy

The tool performs file creation and modification operations: exporting image assets and updating project configuration files (pubspec.yaml). These are reversible write operations (files can be edited or deleted). It does not execute arbitrary code, delete irreversibly, or cause financial impact. The 'set up' language indicates file generation/modification rather than reading or querying.

From the tool's definition Tool description states it 'Export images from Figma nodes and set up Flutter assets directory with pubspec.yaml' — this creates/modifies files (asset exports and pubspec.yaml configuration).

POLICY

How to control export_flutter_assets

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 export_flutter_assets:

policy.json

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

export_flutter_assets 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.

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.
