AI agents call gcloud_list_services to retrieve information from Gcloud without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool exclusively performs information retrieval operations on Cloud Run services. It fetches and displays service details (URLs, revisions, status, timestamps) without creating, modifying, deleting, or executing any resources. The action is read-only with minimal blast radius — an AI agent misusing this tool would only gain visibility into deployed services, not cause operational or financial harm.
From the tool's definition Tool name is 'gcloud_list_services' and description states it 'List[s] Cloud Run services' and 'Returns URL, latest revision, status, and last deployed timestamp' — purely retrieves and queries service metadata with no side effects or state modifications.
Attacks that exploit this kind of access
List Cloud Run services in a given region. Returns URL, latest revision, status, and last deployed timestamp for each service. It is categorised as a Read tool in the Gcloud MCP Server, which means it retrieves data without modifying state.
Register the Gcloud MCP server in PolicyLayer and add a rule for gcloud_list_services: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Gcloud. Nothing to install.
gcloud_list_services is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the gcloud_list_services rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for gcloud_list_services. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
gcloud_list_services is provided by the Gcloud MCP server (prmichaelsen/gcloud-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
gcloud_list_services is one line of Gcloud's registry record.
The record carries the whole server: verified identity, auth posture, risk grade, every tool classified, recommended policy — re-checked continuously.
