Delete a mode from a variable collection. Cannot delete the last mode.
AI agents call figma_delete_mode to permanently remove resources in Figma MCP Bridge — typically in cleanup and lifecycle workflows. It does its job in a single call, and there is no undo.
This tool permanently removes a mode from a Figma variable collection, which cannot be undone. While the impact is scoped to design system metadata rather than entire documents or critical assets, deletion of modes could break design workflows or variable references. The constraint 'Cannot delete the last mode' shows awareness of destructive potential.
From the tool's definition Tool name is 'figma_delete_mode' and description states 'Delete a mode from a variable collection.' The verb 'delete' and explicit destructive capability indicate irreversible data removal.
Documented attack patterns abuse exactly the kind of access figma_delete_mode 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_delete_mode:
{
"version": "1",
"default": "deny",
"hide": [
"figma_delete_mode"
]
} figma_delete_mode disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Delete a mode from a variable collection. Cannot delete the last mode. It is categorised as a Destructive tool in the Figma MCP Bridge MCP Server, which means it can permanently delete or destroy data. Block by default and require explicit approval.
Register the Figma MCP Bridge MCP server in PolicyLayer and add a rule for figma_delete_mode: 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_delete_mode is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.
Yes. Add a rate_limit block to the figma_delete_mode 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_delete_mode. 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_delete_mode 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.
