THE RISK

Medium Risk

Why create_theme needs a policy

The tool creates new Tailwind theme configuration data, which is a reversible modification to project files. It does not execute arbitrary code, delete data, or involve financial operations. While it modifies project state, the changes can be edited or reverted, placing it in the Write category.

From the tool's definition Tool is named 'create_theme' with description 'Generate custom Tailwind theme with AI assistance'. The verb 'generate' and 'create' indicate it produces and stores new configuration data (theme settings).

POLICY

How to control create_theme

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

policy.json

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

create_theme 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.

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