  - name: DATABRICKS_HOST
    value: "https://dbc-XXXXX.cloud.databricks.com"

  - name: DATABRICKS_APP_URL
    value: "https://your-mcp-app.databricksapps.com"
```

```

### Claude Desktop Configuration

```json
{
  "mcpServers": {
    "databricks": {
      "command": "uv",
      "args": [
        "--directory", "/path/to/databricks-mcp-proxy",
        "run",
        "databricks-mcp-proxy"
      ]
    }
  }
}
```
