AI agents call scan_text_nodes to retrieve information from Figma AI Bridge without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only scan to retrieve text node information from a Figma design. It has no side effects, creates no new objects, modifies no existing data, and cannot be used to delete or execute external operations. The blast radius of misuse is minimal—an AI agent could at worst exfiltrate text content from a design, which is a confidentiality concern but not destructive or operationally damaging.
From the tool's definition Tool name 'scan_text_nodes' and description 'Scan all text nodes in the selected Figma node' indicate a query/retrieval operation that reads text content without modifying or deleting data.
Documented attack patterns abuse exactly the kind of access scan_text_nodes 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 scan_text_nodes:
{
"version": "1",
"default": "deny",
"tools": {
"scan_text_nodes": {}
}
}scan_text_nodes is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
Free to start. No card required.
Scan all text nodes in the selected Figma node. It is categorised as a Read tool in the Figma AI Bridge MCP Server, which means it retrieves data without modifying state.
Register the Figma AI Bridge MCP server in PolicyLayer and add a rule for scan_text_nodes: 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.
scan_text_nodes is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the scan_text_nodes 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 scan_text_nodes. 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.
scan_text_nodes 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.
Free to start. No card required.
