Why set_multiple_text_contents needs a policy

This tool creates or modifies data (text content in Figma nodes) in a reversible manner. It is not destructive (text can be changed again), not financial, and not execute (it doesn't run arbitrary code or trigger external operations — it applies a predefined text update).

From the tool's definition Tool name is 'set_multiple_text_contents' and description states it 'Set[s] multiple text contents parallelly in a node' — directly modifies design content in Figma by updating text elements, which is a reversible write operation.

POLICY

How to control set_multiple_text_contents

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 set_multiple_text_contents:

policy.json

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

set_multiple_text_contents 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.

FAQ

Questions about set_multiple_text_contents

What does the set_multiple_text_contents tool do? +

Set multiple text contents parallelly in a node. 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 set_multiple_text_contents? +

Register the Figma AI Bridge MCP server in PolicyLayer and add a rule for set_multiple_text_contents: 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 set_multiple_text_contents? +

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

Can I rate-limit set_multiple_text_contents? +

Yes. Add a rate_limit block to the set_multiple_text_contents 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 set_multiple_text_contents completely? +

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

set_multiple_text_contents 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.
