AI agents call scan_text_nodes to retrieve information from MCP Figma without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool only retrieves information about text nodes within a design document. It performs data retrieval without side effects, aligning with the Read category. Severity is low because scanning design elements poses minimal risk — it cannot modify designs, execute code, delete content, or commit financial transactions.
From the tool's definition Tool description states 'Scan all text nodes in the selected Figma node' — a read-only operation that retrieves/queries text data with no modification, deletion, or execution of external operations.
Attacks that exploit this kind of access
Scan all text nodes in the selected Figma node. It is categorised as a Read tool in the MCP Figma MCP Server, which means it retrieves data without modifying state.
Register the MCP Figma 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 MCP Figma. 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 MCP Figma MCP server (yelowflash09/figma_mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
