To use with Desktop APP, such as Claude, VSCode, Cline, Cherry Studio, Cursor, and so on, add the MCP server config below. On Mac system:

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

On Window system:

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

Also, you can use it on aliyun, modelscope, glama.ai, smithery.ai or others with HTTP, SSE Protocol.

Install the package globally.

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

Run the server with your preferred transport option:

# For SSE transport (default endpoint: /sse)
charts-mcp --transport sse

# For Streamable transport with custom endpoint
charts-mcp --transport streamable

Then you can access the server at:

• SSE transport: http://localhost:1122/sse
• Streamable transport: http://localhost:1122/mcp

Enter the docker directory.

cd docker

Deploy using docker-compose.

docker compose up -d

Then you can access the server at:

• SSE transport: http://localhost:1123/sse
• Streamable transport: http://localhost:1122/mcp

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

MCP Server Chart CLI

Options:
  --transport, -t  Specify the transport protocol: "stdio", "sse", or "streamable" (default: "stdio")
  --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

Sample JSON payloads live under examples/ and are validated by tests:

• Charts: examples/charts/*.basic.json for all chart types (area, bar, boxplot, column, dual-axes, fishbone-diagram, flow-diagram, funnel, histogram, line, liquid, mind-map, network-graph, organization-chart, pie, radar, sankey, scatter, treemap, venn, violin, word-cloud)`
• Maps: examples/maps/pin-map.basic.json, examples/maps/path-map.basic.json, examples/maps/district-map.basic.json

Use them as templates for MCP callTool arguments.

For developers and contributors, we provide a comprehensive visual testing system to validate chart rendering across all three output formats (html, html-url, png).

# 1. Start the renderer server
npm run renderer:dev

# 2. In another terminal, generate test renders
npm run render-examples

# 3. Open the interactive gallery
open test-outputs/index.html

The gallery provides:

• Side-by-side comparison of all formats
• Interactive viewing of each chart
• PNG thumbnails for quick inspection
• File size information and success rates

For detailed information, see Visual Testing Guide.

This server renders charts and maps locally and serves results via local URLs. To enable it for MCP tools, point envs to the built-in endpoints:

• VIS_REQUEST_SERVER=http://localhost:3210/chart
• MAP_REQUEST_SERVER=http://localhost:3210/map

Interactive rendering (HTML) is supported by passing "format": "html" in the tool arguments:

• Charts example (generate_bar_chart): add "format": "html" alongside other fields.
• Maps example (pin/path): include "format": "html" inside the input payload. For example, pin-map arguments:
  • {"title":"Paris Landmarks","data":["Eiffel Tower","Louvre Museum"],"format":"html"}
  • District map example (basic): {"title":"Île-de-France Departments","data":{"name":"Île-de-France","dataType":"enum","dataLabel":"Department","subdistricts":[{"name":"Paris","dataValue":"Capital"},{"name":"Seine-et-Marne","dataValue":"Department"}]},"format":"html"}

Notes:

• HTML pages are served from http://localhost:3210/pages/<id>.html and are interactive (G2Plot for charts, Leaflet for maps).
• PNG results remain the default when format is not provided.

MCP Server Chart includes a built-in renderer. You can customize ports and public base if needed.

{
  "mcpServers": {
    "charts-mcp": {
      "command": "npx",
      "args": [
        "-y",
        "@antv/mcp-server-chart"
      ],
      "env": {
        "VIS_REQUEST_SERVER": "http://localhost:3210/chart",
        "MAP_REQUEST_SERVER": "http://localhost:3210/map"
      }
    }
  }
}

The built-in renderer serves local image URLs under /assets/*. No external chart service is required. For maps, tiles/geocoding are fetched from public OSM services by default.

• 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.

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):

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):

{
  "mcpServers": {
    "charts-mcp": {
      "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.

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.

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