Comprehensive auto layout management with 7 operations: get layout info, set horizontal/vertical/grid/freeform layouts, configure child properties, and reorder children
AI agents use figma_auto_layout to create or update resources in Figma Mcp Write — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Figma Mcp Write environment.
The tool performs reversible modifications to Figma design layouts and child element properties. While it can restructure designs, these changes are not destructive (can be undone) and do not involve deletion, financial transactions, or code execution. It falls squarely in the Write category.
From the tool's definition Tool description states 'set horizontal/vertical/grid/freeform layouts' and 'configure child properties, and reorder children' — these are modification operations.
Documented attack patterns abuse exactly the kind of access figma_auto_layout gives an agent:
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_auto_layout:
{
"version": "1",
"default": "deny",
"tools": {
"figma_auto_layout": {
"limits": [
{
"counter": "figma_auto_layout_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
} figma_auto_layout 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.

Register the Figma Mcp Write MCP server in PolicyLayer and add a rule for figma_auto_layout: 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.
figma_auto_layout is a Write tool with medium risk. Write tools should be rate-limited to prevent accidental bulk modifications.
Yes. Add a rate_limit block to the figma_auto_layout 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 figma_auto_layout. 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.
figma_auto_layout 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.
Start from Figma Mcp Write, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
