THE RISK

Medium Risk

Why create_slide needs a policy

This tool creates new design assets in Figma but does not execute arbitrary code, delete data irreversibly, or move financial resources. The blast radius is moderate—an AI agent could create many unwanted slides, wasting time to clean up, but the impact is limited to design document structure and is fully reversible.

From the tool's definition Tool description states 'Create a single presentation slide in Figma' — the verb 'create' indicates data creation. The tool adds new content to a Figma document reversibly (slides can be edited or deleted later).

POLICY

How to control create_slide

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

policy.json

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

create_slide 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 AI Bridge — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about create_slide

What does the create_slide tool do? +

Create a single presentation slide in Figma. Supports types: title, content, visual, statement, columns, comparison, numbered. It is categorised as a Write tool in the Figma AI Bridge 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_slide? +

Register the Figma AI Bridge MCP server in PolicyLayer and add a rule for create_slide: 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 Figma AI Bridge. Nothing to install.

What risk level is create_slide? +

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

Can I rate-limit create_slide? +

Yes. Add a rate_limit block to the create_slide 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_slide completely? +

Set action: deny in the PolicyLayer policy for create_slide. 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_slide? +

create_slide is provided by the Figma AI Bridge MCP server (renfei-design/figma_ai_bridge). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Figma AI Bridge tool call.

Start from Figma AI Bridge, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
