Scan for child nodes with specific types in the selected Figma node
AI agents call scan_nodes_by_types to retrieve information from Cursor Talk to Figma MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
Even though scan_nodes_by_types only reads data, uncontrolled read access leaks sensitive information and racks up API costs — an agent caught in a retry loop can make thousands of calls a minute without anyone noticing.
Attacks that exploit this kind of access
Scan for child nodes with specific types in the selected Figma node. It is categorised as a Read tool in the Cursor Talk to Figma MCP MCP Server, which means it retrieves data without modifying state.
Register the Cursor Talk to Figma 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 Cursor Talk to Figma MCP. Nothing to install.
scan_nodes_by_types 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_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.
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.
scan_nodes_by_types is provided by the Cursor Talk to Figma MCP server (ysocrius/talk-to-figma-cursor). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
