AI agents call gcloud_get_service 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 retrieves and queries Cloud Run service metadata and configuration. While it accesses potentially sensitive information (environment variables, URLs, scaling configuration), it performs no modifications, deletions, or state changes. It is clearly a Read operation.
From the tool's definition Tool description states it 'Get[s] full Cloud Run service details including URL, env vars, resource limits, scaling config, traffic splits, and latest revision.' The verb 'Get' and the read-only nature of retrieving service configuration and status…
Attacks that exploit this kind of access
Get full Cloud Run service details including URL, env vars, resource limits, scaling config, traffic splits, and latest revision. 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_get_service: 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_get_service 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_get_service 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_get_service. 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_get_service 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.
