list_components

List all components available in a Figma file

Part of the Figma MCP Server server.

list_components is read-only, but an agent in a loop can still rack up calls and cost. PolicyLayer caps every call before it runs. Live in minutes.

AI agents call list_components to retrieve information from Figma MCP Server without modifying any data. This is common in research, monitoring, and reporting workflows where the agent needs context before taking action. Because read operations don't change state, they are generally safe to allow without restrictions -- but you may still want rate limits to control API costs.

Even though list_components only reads data, uncontrolled read access can leak sensitive information or rack up API costs. An agent caught in a retry loop could make thousands of calls per minute. A rate limit gives you a safety net without blocking legitimate use.

Read-only tools are safe to allow by default. No rate limit needed unless you want to control costs.

These attack patterns abuse exactly the kind of access list_components gives an agent. Each links to the full case and the policy that stops it:

Every attack above starts with a tool call. PolicyLayer checks each one against your policy first, so list_components only ever does what you allow.

What does the list_components tool do? +

List all components available 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.

How do I enforce a policy on list_components? +

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.

What risk level is list_components? +

list_components is a Read tool with low risk. Read-only tools are generally safe to allow by default.

Can I rate-limit list_components? +

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.

How do I block list_components completely? +

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.

What MCP server provides list_components? +

list_components is provided by the Figma MCP Server MCP server (@oabolade-pegasus/figma-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.

Enforce policy on every Figma MCP Server tool call.
