Why figma_get_reactions needs a policy

This tool retrieves reaction/interaction metadata from a Figma node without creating, modifying, deleting, or executing any actions. It is purely a query operation that reads existing data from the design document. No reversible or irreversible changes are made, no code execution occurs, and no financial operations are involved.

From the tool's definition Tool name is 'figma_get_reactions' and description states 'get all reactions' and 'Returns the full reactions array'. The verb 'get' and 'Returns' indicate data retrieval with no modification or side effects.

POLICY

How to control figma_get_reactions

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_get_reactions:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "figma_get_reactions": {}
  }
}

figma_get_reactions is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

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.
