AI agents use figma_create_component 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.
Creating a component in Figma is a reversible write operation that modifies the design document by adding new reusable design elements. This does not delete data (ruling out Destructive), execute arbitrary code (ruling out Execute), or involve financial transactions.
From the tool's definition Tool description states 'Create a component.' The server description confirms this server 'enables Claude to read and manipulate Figma documents' and includes 'creating shapes, modifying styles, managing components' as core operations.
Documented attack patterns abuse exactly the kind of access figma_create_component 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_create_component:
{
"version": "1",
"default": "deny",
"tools": {
"figma_create_component": {
"limits": [
{
"counter": "figma_create_component_rate",
"window": "minute",
"max": 30,
"scope": "grant"
}
]
}
}
} figma_create_component 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 component. 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_create_component: 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_create_component 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_create_component 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_create_component. 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_create_component 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.
