WHAT IT DOES

What gcp_lb_list_url_maps does on GCP MCP Server

AI agents call gcp_lb_list_url_maps 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_lb_list_url_maps is rated Low

This tool retrieves and enumerates URL map configurations from Google Cloud Load Balancer. Listing is a read-only query operation that does not modify, delete, or execute any infrastructure changes. The blast radius is minimal: an attacker gains visibility into load balancer routing configuration but cannot alter it or access protected data behind the load balancer without further exploitation.

From the tool's definition Tool name contains 'list' and description states 'List URL maps' — a retrieval operation with no side effects.
