AI agents call gcloud_get_build 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.
The 'gcloud_get_build' tool queries and retrieves metadata and execution details about a Cloud Build resource. It has no side effects—it does not trigger builds, modify configurations, delete resources, or execute arbitrary commands. The worst-case misuse is information disclosure about build configurations or logs, which is a low severity read risk.
From the tool's definition Tool retrieves 'full Cloud Build details including steps, substitutions, images, and per-step timing breakdown' with no modification verbs (create, update, delete) in the description.
Attacks that exploit this kind of access
Get full Cloud Build details including steps, substitutions, images, and per-step timing breakdown. 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_build: 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_build 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_build 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_build. 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_build 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.
