THE RISK

Low Risk

Why scan_nodes_by_types needs a policy

This tool retrieves information about nodes matching specific type filters within a Figma document. It performs no side effects, does not modify design assets, and is purely informational. Querying and listing operations are classified as Read, which carries low severity due to minimal risk of misuse.

From the tool's definition Tool description states it 'Scan for child nodes with specific types' — a retrieval operation with no modification, creation, or deletion of data. The verb 'scan' combined with 'for' indicates a query/search pattern.

POLICY

How to control scan_nodes_by_types

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_nodes_by_types:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "scan_nodes_by_types": {}
  }
}

scan_nodes_by_types is read-only, so it stays allowed — but 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 scan_nodes_by_types

What does the scan_nodes_by_types tool do? +

Scan for child nodes with specific types 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.

How do I enforce a policy on scan_nodes_by_types? +

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

scan_nodes_by_types is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit scan_nodes_by_types? +

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

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

scan_nodes_by_types 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.
