WHAT IT DOES

What gcp_iam_get_project_iam_policy does on GCP MCP Server

AI agents call gcp_iam_get_project_iam_policy to retrieve information from GCP MCP Server without modifying anything. It is typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.

RISK

Why gcp_iam_get_project_iam_policy is rated Low

This tool queries and returns IAM policy data, which is a read operation. However, severity is high because IAM policies contain sensitive security-critical information (who has what permissions), and an AI agent obtaining this data could use it for reconnaissance to identify privilege escalation opportunities, weak access controls, or to exfiltrate information about the security posture.

From the tool's definition 'Get the IAM policy for the project' — retrieves access control configuration without modifying it.

gcp_iam_get_project_iam_policy Allowed

gcp_iam_get_project_iam_policy is read-only, so it stays allowed. Everything else on the server is denied unless you say otherwise.
