## 🤖 Usage

To use with `Desktop APP`, such as Claude, VSCode, [Cline](https://cline.bot/mcp-marketplace), Cherry Studio, Cursor, and so on, add the MCP server config below. On Mac system:

```json
{
  "mcpServers": {
    "mcp-server-chart": {
      "command": "npx",
      "args": ["-y", "@antv/mcp-server-chart"]
    }
  }
}
```

On Window system:

```json
{
  "mcpServers": {
    "mcp-server-chart": {
      "command": "cmd",
      "args": ["/c", "npx", "-y", "@antv/mcp-server-chart"]
    }
  }
}
```

Also, you can use it on [aliyun](https://bailian.console.aliyun.com/?tab=mcp#/mcp-market/detail/antv-visualization-chart), [modelscope](https://www.modelscope.cn/mcp/servers/@antvis/mcp-server-chart), [glama.ai](https://glama.ai/mcp/servers/@antvis/mcp-server-chart), [smithery.ai](https://smithery.ai/server/@antvis/mcp-server-chart) or others with HTTP, SSE Protocol.

## 🚰 Run with SSE or Streamable transport

### Run directly

Install the package globally.

```bash
npm install -g @antv/mcp-server-chart
```

Run the server with your preferred transport option:

```bash
# For SSE transport (default endpoint: /sse)
mcp-server-chart --transport sse

# For Streamable transport with custom endpoint
mcp-server-chart --transport streamable
```

Then you can access the server at:

- SSE transport: `http://localhost:1122/sse`
- Streamable transport: `http://localhost:1122/mcp`

### Docker deploy

Enter the docker directory.

```bash
cd docker
```

Deploy using docker-compose.

```bash
docker compose up -d
```

Then you can access the server at:

- SSE transport: `http://localhost:1123/sse`
- Streamable transport: `http://localhost:1122/mcp`

## 🎮 CLI Options

You can also use the following CLI options when running the MCP server. Command options by run cli with `-H`.

```plain
MCP Server Chart CLI

Options:
  --transport, -t  Specify the transport protocol: "stdio", "sse", or "streamable" (default: "stdio")
  --host, -h       Specify the host for SSE or streamable transport (default: localhost)
  --port, -p       Specify the port for SSE or streamable transport (default: 1122)
  --endpoint, -e   Specify the endpoint for the transport:
                   - For SSE: default is "/sse"
                   - For streamable: default is "/mcp"
  --help, -H       Show this help message
```

## ⚙️ Environment Variables

| Variable             | Description                                                | Default                                      | Example                                       |
| -------------------- | :--------------------------------------------------------- | -------------------------------------------- | --------------------------------------------- |
| `VIS_REQUEST_SERVER` | Custom chart generation service URL for private deployment | `https://antv-studio.alipay.com/api/gpt-vis` | `https://your-server.com/api/chart`           |
| `SERVICE_ID`         | Service identifier for chart generation records            | -                                            | `your-service-id-123`                         |
| `DISABLED_TOOLS`     | Comma-separated list of tool names to disable              | -                                            | `generate_fishbone_diagram,generate_mind_map` |

### 📠 Private Deployment

`MCP Server Chart` provides a free chart generation service by default. For users with a need for private deployment, they can try using `VIS_REQUEST_SERVER` to customize their own chart generation service.

```json
{
  "mcpServers": {
    "mcp-server-chart": {
      "command": "npx",
      "args": ["-y", "@antv/mcp-server-chart"],
      "env": {
        "VIS_REQUEST_SERVER": "<YOUR_VIS_REQUEST_SERVER>"
      }
    }
  }
}
```

You can use AntV's project [GPT-Vis-SSR](https://github.com/antvis/GPT-Vis/tree/main/bindings/gpt-vis-ssr) to deploy an HTTP service in a private environment, and then pass the URL address through env `VIS_REQUEST_SERVER`.

- **Method**: `POST`
- **Parameter**: Which will be passed to `GPT-Vis-SSR` for rendering. Such as, `{ "type": "line", "data": [{ "time": "2025-05", "value": 512 }, { "time": "2025-06", "value": 1024 }] }`.
- **Return**: The return object of HTTP service.
  - **success**: `boolean` Whether generate chart image successfully.
  - **resultObj**: `string` The chart image url.
  - **errorMessage**: `string` When `success = false`, return the error message.

> [!NOTE]
> The private deployment solution currently does not support geographic visualization chart generation include 3 tools: `geographic-district-map`, `geographic-path-map`, `geographic-pin-map`.

### 🗺️ Generate Records

By default, users are required to save the results themselves, but we also provide a service for viewing the chart generation records, which requires users to generate a service identifier for themselves and configure it.

Use Alipay to scan and open the mini program to generate a personal service identifier (click the "My" menu below, enter the "My Services" page, click the "Generate" button, and click the "Copy" button after success):

<img alt="my service identifier website" width="240" src="https://mdn.alipayobjects.com/huamei_dxq8v0/afts/img/dASoTLt6EywAAAAARqAAAAgADu43AQFr/fmt.webp" />

Next, you need to add the `SERVICE_ID` environment variable to the MCP server configuration. For example, the configuration for Mac is as follows (for Windows systems, just add the `env` variable):

```json
{
  "mcpServers": {
    "AntV Map": {
      "command": "npx",
      "args": ["-y", "@antv/mcp-server-chart"],
      "env": {
        "SERVICE_ID": "***********************************"
      }
    }
  }
}
```

After updating the MCP Server configuration, you need to restart your AI client application and check again whether you have started and connected to the MCP Server successfully. Then you can try to generate the map again. After the generation is successful, you can go to the "My Map" page of the mini program to view your map generation records.

### 🎛️ Tool Filtering

You can disable specific chart generation tools using the `DISABLED_TOOLS` environment variable. This is useful when certain tools have compatibility issues with your MCP client or when you want to limit the available functionality.

```json
{
  "mcpServers": {
    "mcp-server-chart": {
      "command": "npx",
      "args": ["-y", "@antv/mcp-server-chart"],
      "env": {
        "DISABLED_TOOLS": "generate_fishbone_diagram,generate_mind_map"
      }
    }
  }
}
```

**Available tool names for filtering** See the [✨ Features](#-features).
