AI agents use figma_clone_nodes to create or update resources in Figma MCP Bridge — usually the action step of a workflow, after the agent has gathered context. Every call changes real data in your Figma MCP Bridge environment.
Cloning/duplicating nodes is a reversible Write operation that creates new data (duplicate design elements) without destructive consequences. It does not delete, execute arbitrary code, or trigger financial operations. The blast radius is medium because an AI agent could clutter designs with unwanted duplicates, but the operation is easily undone through standard Figma undo/delete functionality.
From the tool's definition Tool name 'figma_clone_nodes' with description 'Duplicate nodes' — creates new design elements by copying existing ones in Figma documents.
Documented attack patterns abuse exactly the kind of access figma_clone_nodes gives an agent:
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_clone_nodes:
{
"version": "1",
"default": "deny",
"tools": {
"figma_clone_nodes": {
"limits": [
{
"counter": "figma_clone_nodes_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
} figma_clone_nodes 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.

Duplicate nodes. 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.
Register the Figma MCP Bridge MCP server in PolicyLayer and add a rule for figma_clone_nodes: 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.
figma_clone_nodes 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_clone_nodes 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_clone_nodes. 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_clone_nodes 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.
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.
