resolve_components · Figma Spec MCP: Risk & Policy

WHAT IT DOES

What resolve_components does on Figma Spec

AI agents use resolve_components to create or update resources in Figma Spec — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Figma Spec environment.

WHY IT NEEDS A POLICY

Why resolve_components needs a policy

An AI agent can call resolve_components faster than any human can review — one bad instruction and it creates or modifies resources in Figma Spec by the hundred, each call as confident as the last.

Verdict

resolve_components Rate-limited

resolve_components stays usable, but capped — an agent stuck in a loop can't make hundreds of changes a minute. Everything else on the server is denied unless you say otherwise.

FAQ

Questions about resolve_components

What does the resolve_components tool do? +

Scans a Figma subtree or full file for instances, resolves each unique component through the file component map and Figma component API, and returns the source file and node for each instance. It is categorised as a Write tool in the Figma Spec MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on resolve_components? +

Register the Figma Spec MCP server in PolicyLayer and add a rule for resolve_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 Spec. Nothing to install.

What risk level is resolve_components? +

resolve_components is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.

Can I rate-limit resolve_components? +

Yes. Add a rate_limit block to the resolve_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 resolve_components completely? +

Set action: deny in the PolicyLayer policy for resolve_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 resolve_components? +

resolve_components is provided by the Figma Spec MCP server (zaferdace/figma-spec-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
