AI agents call list-files to retrieve information from Figma MCP Server 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 query operation that retrieves or lists existing files from a Figma project. It does not create, modify, delete, or execute any external operations. The blast radius of misuse is minimal—an agent could enumerate files but cannot alter or harm data. This is a standard Read operation with low severity.
From the tool's definition Tool name 'list-files' and description 'List files in a Figma project' indicates retrieval of file metadata without modification or deletion. No side effects or destructive operations are implied.
Documented attack patterns abuse exactly the kind of access list-files gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Figma MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for list-files:
{
"version": "1",
"default": "deny",
"tools": {
"list-files": {}
}
}list-files is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List files in a Figma project. It is categorised as a Read tool in the Figma MCP Server MCP Server, which means it retrieves data without modifying state.
Register the Figma MCP Server MCP server in PolicyLayer and add a rule for list-files: 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 MCP Server. Nothing to install.
list-files 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 list-files 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 list-files. 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.
list-files is provided by the Figma MCP Server MCP server (timholden/figma-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
