## Quick Start

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

```
"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

```bash
# 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:

```bash
gcloud auth application-default login
```

Configure the `mcpServers` in your client:

```json
{
  "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

```bash
# Build the project
pnpm build

# Start the server
pnpm start
```

### Development mode

```bash
# 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
