WHAT IT DOES

What gcp_secrets_list_versions does on GCP MCP Server

AI agents call gcp_secrets_list_versions 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_secrets_list_versions is rated Low

This tool queries and retrieves metadata about secret versions without creating, modifying, deleting, or executing operations. It has minimal blast radius—an AI agent using it can only discover information about existing secrets, not alter them. Severity is low because listing secret versions does not expose secret values themselves and does not modify state.

From the tool's definition Tool name 'gcp_secrets_list_versions' and description 'List versions of a secret' indicate a retrieval operation with no modifications or side effects. The verb 'list' is a typical Read category operation.
