gcp_build_cancel_build

What gcp_build_cancel_build does on GCP MCP Server

AI agents invoke gcp_build_cancel_build to trigger actions in GCP MCP Server. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call: builds kicked off, notifications sent, workflows started.

Why gcp_build_cancel_build is rated High

This tool triggers an external operation (cancellation of a Cloud Build build) with effects that depend on which build is targeted. While cancellation itself is technically reversible (the build can be restarted), it immediately halts an in-progress operation and is categorized as Execute rather than Write because it acts upon an external service's runtime state.

From the tool's definition Tool name 'gcp_build_cancel_build' and description 'Cancel a running Cloud Build build' indicate an action that terminates an external operation (a build process) whose side effects are not reversible—once cancelled, the build stops and resources are released.

The rule that runs gcp_build_cancel_build safely

PolicyLayer is an MCP gateway: it sits between your AI agents and GCP MCP Server, and checks every tool call against a rule you set before the call runs. Nothing changes on the server itself. For gcp_build_cancel_build, this is the rule to start with:

{
  "version": "1",
  "default": "deny",
  "tools": {
    "gcp_build_cancel_build": {
      "limits": [
        {
          "counter": "gcp_build_cancel_build_rate",
          "window": "minute",
          "max": 10,
          "scope": "grant"
        }
      ]
    }
