• "Query traces for service checkout-api in project ecommerce-prod-321"

Quick Start

Once configured, you can interact with Google Cloud services using natural language:

Copy code
"What are my current billing costs for project my-webapp-prod-123?"
"Show me errors from project ecommerce-api-456 in the last hour"
"Check if I have permission to deploy to Cloud Run in project microservices-789"
"Find logs containing 'database timeout' from project backend-prod-321 yesterday"
"List Spanner databases in instance prod-db for project data-store-654"
"What's the CPU usage of Compute Engine instances in project infrastructure-987?"

Authentication

This server supports two methods of authentication with Google Cloud:

1. Service Account Key File (Recommended): Set the GOOGLE_APPLICATION_CREDENTIALS environment variable to the path of your service account key file. This is the standard Google Cloud authentication method.

2. Environment Variables: Set GOOGLE_CLIENT_EMAIL and GOOGLE_PRIVATE_KEY environment variables directly. This is useful for environments where storing a key file is not practical.

The server will also use the GOOGLE_CLOUD_PROJECT environment variable if set, otherwise it will attempt to determine the project ID from the authentication credentials.

Installation

bashCopy code
# Clone the repository
git clone https://github.com/krzko/google-cloud-mcp.git
cd google-cloud-mcp

# Install dependencies
pnpm install

# Build
pnpm build

Authenticate to Google Cloud:

bashCopy code
gcloud auth application-default login

Configure the mcpServers in your client:

jsonCopy code
{
  "mcpServers": {
      "google-cloud-mcp": {
          "command": "node",
          "args": [
              "/Users/foo/code/google-cloud-mcp/dist/index.js"
          ],
          "env": {
              "GOOGLE_APPLICATION_CREDENTIALS": "/Users/foo/.config/gcloud/application_default_credentials.json"
          }
      }
  }
}

Development

Starting the server

bashCopy code
# Build the project
pnpm build

# Start the server
pnpm start

Development mode

bashCopy code
# Build the project
pnpm build

# Start the server and inspector
npx -y @modelcontextprotocol/inspector node dist/index.js

Troubleshooting

Server Timeout Issues

If you encounter timeout issues when running the server with Smithery, try the following:

1. Enable debug logging by setting debug: true in your configuration
2. Ensure lazyAuth: true is set to defer authentication until it's actually needed
3. Ensure your credentials file is accessible and valid
4. Check the logs for any error messages

Important: Authentication is still required for operation, but with lazy loading enabled, the server will start immediately and authenticate when needed rather than during initialization.

Authentication Issues

The server supports two methods of authentication:

1. Service Account Key File: Set GOOGLE_APPLICATION_CREDENTIALS environment variable to the path of your service account key file
2. Environment Variables: Set GOOGLE_CLIENT_EMAIL and GOOGLE_PRIVATE_KEY environment variables

If you're having authentication issues, make sure:

• Your service account has the necessary permissions
• The key file is properly formatted and accessible
• Environment variables are correctly set
