WHAT IT DOES

What gcp_rm_list_liens does on GCP MCP Server

AI agents call gcp_rm_list_liens 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_rm_list_liens is rated Low

This tool retrieves information about resource management liens (deletion restrictions) on a GCP project. It performs a read-only query with no side effects, state changes, or capability to modify, delete, or execute actions. The blast radius of misuse is minimal—an unauthorized listing of liens reveals only existing restriction metadata, not sensitive data or infrastructure details.

From the tool's definition Tool name includes 'list' and description states 'List liens on a project', which is a read-only query operation that retrieves deletion restriction metadata without modifying any resources.
