This tool changes existing design data (text styling) but does not delete or permanently destroy content. The changes are reversible through undo/redo in Figma, making it a Write operation rather than Destructive. Severity is medium because misuse could affect document aesthetics and user experience, but the impact is limited to style properties and recoverable.

From the tool's definition Tool modifies text font properties in Figma documents. The server description states it enables Claude to 'manipulate Figma documents' through operations including 'modifying styles'.

How to control figma_set_text_style

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

policy.json
{
  "version": "1",
  "default": "deny",
  "tools": {
    "figma_set_text_style": {
      "limits": [
        {
          "counter": "figma_set_text_style_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}
