AI agents use create_text to create or update resources in Figma AI Bridge — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Figma AI Bridge environment.
The tool creates new content (text elements) in Figma, which is a Write operation. It is reversible (the text can be deleted), so it does not qualify as Destructive. The severity is medium because misuse could create numerous unwanted text elements in a design document, but the impact is limited to a single asset type and easily recoverable.
From the tool's definition Tool name 'create_text' and description 'Create a new text element in Figma' indicate data creation. This is a reversible write operation that adds a new design element to a Figma document.
Documented attack patterns abuse exactly the kind of access create_text gives an agent:
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_text:
{
"version": "1",
"default": "deny",
"tools": {
"create_text": {
"limits": [
{
"counter": "create_text_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
}create_text 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 new text element in Figma. 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.
Register the Figma AI Bridge MCP server in PolicyLayer and add a rule for create_text: 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.
create_text is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the create_text 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.
Set action: deny in the PolicyLayer policy for create_text. 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.
create_text 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.
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.
