AI agents call search_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.
The search_files tool performs a retrieval operation (search) against Figma files, returning matching results. This is a read-only action with no capability to modify, delete, or execute code. Even if misused by an agent, it cannot alter state or cause financial harm—it only returns information. Severity is low due to minimal blast radius.
From the tool's definition Tool is described as 'Search for Figma files by name or keywords' — a query operation that retrieves data without modification or side effects.
Documented attack patterns abuse exactly the kind of access search_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 search_files:
{
"version": "1",
"default": "deny",
"tools": {
"search_files": {}
}
}search_files is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Search for Figma files by name or keywords. 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 search_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.
search_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 search_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 search_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.
search_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.
