Why meta_get_pixel needs a policy

This tool retrieves information about a Meta Pixel configuration without modifying, deleting, or executing any operations. It is a straightforward read/query operation that returns data. The severity is low because pixel metadata exposure has minimal direct impact on business operations or user privacy in isolation.

From the tool's definition Tool name is 'meta_get_pixel' and description states it 'Gets details for a single Meta Pixel.' The verb 'gets' and the absence of modification language indicate a retrieval operation.

POLICY

How to control meta_get_pixel

PolicyLayer is an MCP gateway — it sits between your AI agents and Meta MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for meta_get_pixel:

policy.json

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

meta_get_pixel 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 Meta MCP Server — nothing to install.
Add this policy — paste it, or build it visually.
Point your MCP client (Claude, Cursor, anything) at your gateway URL.
