THE RISK

Why figma_search_variables needs a policy

The tool searches and retrieves variable metadata by pattern matching. It performs no creation, modification, deletion, or execution of code. The comparison to get_local_variables confirms it is a read-only query operation. The blast radius of misuse is minimal—an agent could retrieve unintended variable names but cannot modify or delete them.

From the tool's definition Tool description states 'Search for variables by name pattern' - a query operation with no modification capability. Compared favorably to 'get_local_variables' as a more efficient retrieval method.

POLICY

How to control figma_search_variables

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_search_variables:

policy.json

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

figma_search_variables 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.
