2. Create a new project
3. Navigate to **APIs & Services → Credentials**
4. Click **Create Credentials → OAuth Client ID**
5. Select **Desktop Application**
6. Download credentials

### 2. Enable APIs

Click to enable each API:

- [Calendar](https://console.cloud.google.com/flows/enableapi?apiid=calendar-json.googleapis.com)
- [Drive](https://console.cloud.google.com/flows/enableapi?apiid=drive.googleapis.com)
- [Gmail](https://console.cloud.google.com/flows/enableapi?apiid=gmail.googleapis.com)
- [Docs](https://console.cloud.google.com/flows/enableapi?apiid=docs.googleapis.com)

### 3. First Authentication

When you first call a tool:
1. Server returns an authorization URL
2. Open URL in browser, authorize access
3. Paste the authorization code when prompted
4. Credentials are cached for future use

## 🚀 Transport Modes

### Stdio (Default)

Best for Claude Desktop and local MCP clients:

```bash
uvx workspace-mcp
```

### HTTP (Streamable)

For web interfaces, debugging, or multi-client setups:

```bash
uvx workspace-mcp --transport streamable-http
```

Access at `http://localhost:8000/mcp/`

### Docker

```bash
docker build -t workspace-mcp .
docker run -p 8000:8000 \
  -e GOOGLE_OAUTH_CLIENT_ID="..." \
  -e GOOGLE_OAUTH_CLIENT_SECRET="..." \
  workspace-mcp --transport streamable-http
```

---

## 🔧 Client Configuration

### Claude Desktop

```json
{
  "mcpServers": {
    "google_workspace": {
      "command": "uvx",
      "args": ["workspace-mcp", "--tool-tier", "core"],
      "env": {
        "GOOGLE_OAUTH_CLIENT_ID": "your-client-id",
        "GOOGLE_OAUTH_CLIENT_SECRET": "your-secret",
        "OAUTHLIB_INSECURE_TRANSPORT": "1"
      }
    }
  }
}
```

### VS Code

```json
{
  "servers": {
    "google-workspace": {
      "url": "http://localhost:8000/mcp/",
      "type": "http"
    }
  }
}
```

### Claude Code

```bash
claude mcp add --transport http workspace-mcp http://localhost:8000/mcp
```

```

### Key Patterns

**Service Decorator:** All tools use `@require_google_service()` for automatic authentication with 30-minute service caching.

```python
@server.tool()
@require_google_service("gmail", "gmail_read")
async def search_gmail_messages(service, user_google_email: str, query: str):
    # service is injected automatically
    ...
```

**Multi-Service Tools:** Some tools need multiple APIs:

```python
@require_multiple_services([
    {"service_type": "drive", "scopes": "drive_read", "param_name": "drive_service"},
    {"service_type": "docs", "scopes": "docs_read", "param_name": "docs_service"},
])
async def get_doc_content(drive_service, docs_service, ...):
    ...
```
