Why gcp-iam-get-project-policy needs a policy

This tool queries and retrieves IAM policy information for a GCP project, which is a read-only operation with no side effects. However, IAM policies are sensitive security-critical data that could reveal access control configuration; if an AI agent obtains and exfiltrates this information, it could enable privilege escalation attacks or social engineering.

From the tool's definition Tool name contains 'get' and description says 'Retrieve the IAM policy'; retrieves policy data without modification.

How to control gcp-iam-get-project-policy

PolicyLayer is an MCP gateway — it sits between your AI agents and Google Cloud MCP Server, and nothing reaches the server without passing your rules. This is the rule we recommend for gcp-iam-get-project-policy:

policy.json

{
  "version": "1",
  "default": "deny",
  "tools": {
    "gcp-iam-get-project-policy": {}
  }
}

gcp-iam-get-project-policy 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 Google Cloud 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.
