AI agents use figma_move_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.
Moving nodes modifies the Figma document state reversibly—positions can be changed again or undone. This is a Write operation (modify data without deletion). Severity is medium because misuse could disrupt a design document's layout and require manual correction, but changes are non-destructive and reversible within Figma's undo system.
From the tool's definition Tool name 'figma_move_nodes' and description 'Move nodes' indicate modification of Figma document elements. The mention of 'relative=true for offset' confirms positional manipulation of existing nodes.
Documented attack patterns abuse exactly the kind of access figma_move_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_move_nodes:
{
"version": "1",
"default": "deny",
"tools": {
"figma_move_nodes": {
"limits": [
{
"counter": "figma_move_nodes_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
} figma_move_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.
Free to start. No card required.
Move nodes. Use relative=true for offset. 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_move_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_move_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_move_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_move_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_move_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.
Free to start. No card required.
