THE RISK

Medium Risk

Why create_ellipse needs a policy

This tool creates new design elements (ellipses) in Figma, which are persistent but reversible changes to a design file. It falls under Write category as it modifies the design by adding new objects, not deleting or executing arbitrary code. Severity is medium because misuse could clutter or corrupt a design file, but the changes can be undone through Figma's undo functionality or by deleting the created objects.

From the tool's definition Tool name 'create_ellipse' and description 'Create a new ellipse in Figma' indicate this creates new design objects within Figma, which is a reversible modification of the design canvas.

POLICY

How to control create_ellipse

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 create_ellipse:

policy.json

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

create_ellipse 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.

FAQ

Questions about create_ellipse

What does the create_ellipse tool do? +

Create a new ellipse in Figma. It is categorised as a Write tool in the Claude Talk to Figma MCP MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on create_ellipse? +

Register the Claude Talk to Figma MCP server in PolicyLayer and add a rule for create_ellipse: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Claude Talk to Figma MCP. Nothing to install.

What risk level is create_ellipse? +

create_ellipse is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit create_ellipse? +

Yes. Add a rate_limit block to the create_ellipse rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.

How do I block create_ellipse completely? +

Set action: deny in the PolicyLayer policy for create_ellipse. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.

What MCP server provides create_ellipse? +

create_ellipse is provided by the Claude Talk to Figma MCP server (arinspunk/claude-talk-to-figma-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Claude Talk to Figma MCP tool call.

Start from Claude Talk to Figma MCP, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
