THE RISK

Medium Risk

Why figma_hierarchy needs a policy

This tool modifies the organization and structure of Figma design elements (grouping, parenting, reordering, moving between pages) but all operations are reversible. Users can ungroup, unparent, reorder, and move elements back, making it Write rather than Destructive. The blast radius is limited to design structure reorganization without data loss or external side effects, justifying medium severity.

From the tool's definition Tool description states 'Group, ungroup, parent, unparent, order by index/depth, or move nodes between pages' — these are all reversible modifications to design hierarchy and structure.

POLICY

How to control figma_hierarchy

PolicyLayer is an MCP gateway — it sits between your AI agents and Figma Mcp Write, and nothing reaches the server without passing your rules. This is the rule we recommend for figma_hierarchy:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "figma_hierarchy": {
      "limits": [
        {
          "counter": "figma_hierarchy_rate",
          "window": "minute",
          "max": 30,
          "scope": "grant"
        }
      ]
    }
  }
}

figma_hierarchy 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.

Create a free account and register Figma Mcp Write — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

Questions about figma_hierarchy

What does the figma_hierarchy tool do? +

Group, ungroup, parent, unparent, order by index/depth, or move nodes between pages. It is categorised as a Write tool in the Figma Mcp Write MCP Server, which means it can create or modify data. Consider rate limits to prevent runaway writes.

How do I enforce a policy on figma_hierarchy? +

Register the Figma Mcp Write MCP server in PolicyLayer and add a rule for figma_hierarchy: 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 Write. Nothing to install.

What risk level is figma_hierarchy? +

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

Can I rate-limit figma_hierarchy? +

Yes. Add a rate_limit block to the figma_hierarchy 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 figma_hierarchy completely? +

Set action: deny in the PolicyLayer policy for figma_hierarchy. 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 figma_hierarchy? +

figma_hierarchy is provided by the Figma Mcp Write MCP server (oo/figma-mcp-write-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 Write tool call.
