THE RISK

Why figma_remove_reaction needs a policy

Removing a reaction from a node is an irreversible deletion of that reaction configuration. Unlike modifications that can be undone by updating a value, removing an element from an array by index destroys it, and there is no indication of an undo mechanism. Severity is medium since it affects only a single interaction/prototype reaction on a node rather than entire documents or components.

From the tool's definition 'remove a reaction from a node by its zero-based index in the reactions array'

POLICY

How to control figma_remove_reaction

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_remove_reaction:

policy.json

{
  "version": "1",
  "default": "deny",
  "hide": [
    "figma_remove_reaction"
  ]
}

figma_remove_reaction disappears from the agent's tool list entirely, and any attempt to call it is denied. The rest of the server keeps working.

Create a free account and register Figma MCP Bridge — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.

Questions about figma_remove_reaction

What does the figma_remove_reaction tool do? +

Prototype: remove a reaction from a node by its zero-based index in the reactions array. Use figma_get_reactions first to find the index. 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.

How do I enforce a policy on figma_remove_reaction? +

Register the Figma MCP Bridge MCP server in PolicyLayer and add a rule for figma_remove_reaction: 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.

What risk level is figma_remove_reaction? +

figma_remove_reaction is a Destructive tool with critical risk. Critical-risk tools should be blocked by default and only enabled with explicit human approval.

Can I rate-limit figma_remove_reaction? +

Yes. Add a rate_limit block to the figma_remove_reaction 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.

How do I block figma_remove_reaction completely? +

Set action: deny in the PolicyLayer policy for figma_remove_reaction. 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.

What MCP server provides figma_remove_reaction? +

figma_remove_reaction 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.
