Implementation Reference

• src/gcp/billing.ts:37-160 (handler)

  The main async handler function for the 'gcp_billing_info' tool. It queries GCP billing information using gcloud commands, handles permissions, fetches budget info, and formats output as text or JSON.

  export async function gcpBillingInfo(args: GcpBillingInfoArgs) {
    try {
      const projectId = await getProjectId(args.project_id);
  
      // Get billing account linked to project
      const billingCommand = `billing projects describe ${projectId} --format=json`;
      let billingInfo: any = {};
  
      try {
        const result = await executeGcloud(billingCommand, 15000);
        billingInfo = JSON.parse(result.stdout || '{}');
      } catch (error: any) {
        // Billing API might not be enabled or no permission
        if (error.type === 'PERMISSION_DENIED') {
          return {
            content: [
              {
