Get all override properties from a selected component instance. These overrides can be applied to other instances, which will swap them to match the source component.
AI agents call get_instance_overrides to retrieve information from Figma AI Bridge without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read operation that retrieves override properties from a component instance for inspection or reuse. It does not create, modify, delete, or execute external operations. While the description mentions overrides 'can be applied' to other instances, this tool itself only gets/reads the data. The actual application of overrides to other instances would be a separate Write or Execute operation.
From the tool's definition Tool name and description indicate retrieval of override properties: 'Get all override properties from a selected component instance.' The operation reads/queries existing data without modifying or deleting anything.
Documented attack patterns abuse exactly the kind of access get_instance_overrides gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Figma AI Bridge, and nothing reaches the server without passing your rules. This is the rule we recommend for get_instance_overrides:
{
"version": "1",
"default": "deny",
"tools": {
"get_instance_overrides": {}
}
}get_instance_overrides is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get all override properties from a selected component instance. These overrides can be applied to other instances, which will swap them to match the source component. It is categorised as a Read tool in the Figma AI Bridge MCP Server, which means it retrieves data without modifying state.
Register the Figma AI Bridge MCP server in PolicyLayer and add a rule for get_instance_overrides: 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 AI Bridge. Nothing to install.
get_instance_overrides is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the get_instance_overrides 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 get_instance_overrides. 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.
get_instance_overrides is provided by the Figma AI Bridge MCP server (renfei-design/figma_ai_bridge). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Figma AI Bridge, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
