THE RISK

Medium Risk

Why figma_set_layout_align needs a policy

This tool modifies design properties (alignment, growth, positioning) within a Figma document but does not create new elements, execute code, delete content, or move money. The changes are reversible—layout properties can be adjusted back. The medium severity reflects that misuse could disrupt design layouts, but the blast radius is limited to visual/design properties in a single document that can be easily undone.

From the tool's definition Tool description states it 'Set[s] how a child behaves within an auto-layout frame' and 'Controls individual alignment' and 'growth' properties. These are modifications to design properties that create or alter layout configurations.

POLICY

How to control figma_set_layout_align

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

policy.json

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

figma_set_layout_align 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.

Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

FAQ

Questions about figma_set_layout_align

What does the figma_set_layout_align tool do? +

Set how a child behaves within an auto-layout frame. Controls individual alignment (STRETCH), growth (fill container), and absolute positioning. It is categorised as a Write tool in the Figma MCP Bridge 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_set_layout_align? +

Register the Figma MCP Bridge MCP server in PolicyLayer and add a rule for figma_set_layout_align: 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 Bridge. Nothing to install.

What risk level is figma_set_layout_align? +

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

Can I rate-limit figma_set_layout_align? +

Yes. Add a rate_limit block to the figma_set_layout_align 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_set_layout_align completely? +

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

figma_set_layout_align is provided by the Figma MCP Bridge MCP server (magic-spells/figma-mcp-bridge). 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 Bridge tool call.

Start from Figma MCP Bridge, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
