AI agents call list_components 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 queries and returns a list of components from a Figma file. It performs no mutations, deletions, or external operations—purely informational retrieval. The blast radius of misuse is minimal, as an AI agent listing components cannot cause data loss, unauthorized changes, or financial harm.
From the tool's definition Tool name 'list_components' and description 'List all components in a Figma file' indicate a retrieval/query operation with no modification or side effects.
Documented attack patterns abuse exactly the kind of access list_components 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_components:
{
"version": "1",
"default": "deny",
"tools": {
"list_components": {}
}
}list_components is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

List all components in a Figma file. 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_components: 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_components 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_components 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_components. 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_components 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.
