MCP Server Chart

MCP Server Chart

A Model Context Protocol server for generating charts using AntV. We can use this mcp server for _chart generation_ and _data analysis_.

This is a TypeScript-based MCP server that provides chart generation capabilities. It allows you to create various types of charts through MCP tools. You can also use it in Dify.

16. generate_path_map - Generate a path-map, used to display route planning results for POIs.
17. generate_pie_chart: Generate a pie chart, used to display the proportion of data, dividing it into parts represented by sectors showing the percentage of each part.
18. generate_pin_map - Generate a pin-map, used to show the distribution of POIs.
19. generate_radar_chart: Generate a radar chart, used to display multi-dimensional data comprehensively, showing multiple dimensions in a radar-like format.
20. generate_sankey_chart: Generate a sankey chart, used to display data flow and volume, representing the movement of data between different nodes in a Sankey-style format.
21. generate_scatter_chart: Generate a scatter plot, used to display the relationship between two variables, showing data points as scattered dots on a coordinate system.
22. generate_treemap_chart: Generate a treemap, used to display hierarchical data, showing data in rectangular forms where the size of rectangles represents the value of the data.
23. generate_venn_chart: Generate a venn diagram, used to display relationships between sets, including intersections, unions, and differences.
24. generate_violin_chart: Generate a violin plot, used to display the distribution of data, combining features of boxplots and density plots to provide a more detailed view of the data distribution.
25. generate_word_cloud_chart: Generate a word-cloud, used to display the frequency of words in textual data, with font sizes indicating the frequency of each word.
26. generate_spreadsheet: Generate a spreadsheet or pivot table for displaying tabular data. When 'rows' or 'values' fields are provided, it renders as a pivot table (cross-tabulation); otherwise, it renders as a regular table.

[!NOTE]

The above geographic visualization chart generation tool uses AMap service and currently only supports map generation within China.

🤖 Usage

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

On Window system:

{

"mcpServers": { "mcp-server-chart": { "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.

🎨 Skill Usage

If you are using an AI IDE with skill support (like Claude Code), you can use the chart-visualization skill to automatically select the best chart type and generate visualizations.

You can add the skill from https://github.com/antvis/chart-visualization-skills using:

npx skills add antvis/chart-visualization-skills

Then provide your data or describe the visualization you want. The skill will intelligently choose from 25+ chart types and generate the chart for you.

🚰 Run with SSE or Streamable transport

Run directly

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)

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.

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

🎮 CLI Options

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") --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

📠 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.

{

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

You can use AntV's project 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" butto
