ECharts MCP server

ECharts MCP Server is a powerful tool that generates high-quality chart images from ECharts configurations. It integrates easily with AI assistants through the Model Context Protocol (MCP), allowing you to create beautiful visualizations for various chart types including bar, line, pie, and scatter charts.

Installation

Using NPX

The simplest way to use the ECharts MCP server is via NPX:

1. Create or update your .cursor/mcp.json configuration file:

{
  "mcpServers": {
    "echarts-mcp": {
      "command": "npx",
      "args": ["echarts-mcp"]
    }
  }
}

Running from Source

If you prefer to run the server from source:

# Clone the repository
git clone https://github.com/w2xi/echarts-mcp.git
cd echarts-mcp

# Install dependencies
npm install

# Run the server
npm start

Then configure your MCP client by updating your .cursor/mcp.json:

{
  "mcpServers": {
    "echarts-mcp": {
      "command": "node",
      "args": ["/path/to/echarts-mcp/cli.js"],
      "env": {}
    }
  }
}

Usage

Making Chart Requests

Once configured, you can request chart generation through your AI assistant using natural language prompts such as:

• "Generate a bar chart showing sales data for the last 6 months"
• "Create a pie chart displaying market share distribution"
• "Make a line chart with temperature data over time"

Configuration Parameters

When generating charts, you can customize these parameters:

• width: Chart width in pixels (e.g., 1000)
• height: Chart height in pixels (e.g., 500)
• echarts: ECharts configuration object as string

ECharts Configuration Example

Here's an example of an ECharts configuration for a simple bar chart:

{
  backgroundColor: '#fff',
  title: {
    text: 'Monthly Sales Data'
  },
  tooltip: {},
  legend: {
    data: ['Sales']
  },
  xAxis: {
    data: ['Jan', 'Feb', 'Mar', 'Apr', 'May', 'Jun']
  },
  yAxis: {},
  series: [{
    name: 'Sales',
    type: 'bar',
    data: [120, 200, 150, 80, 70, 110]
  }]
}

Chart Types

The server supports various chart types including:

• Bar charts
• Line charts
• Pie charts
• Scatter plots
• And many more available in the ECharts library

How to install this MCP server

For Claude Code

To add this MCP server to Claude Code, run this command in your terminal:

claude mcp add-json "echarts-mcp" '{"command":"npx","args":["echarts-mcp"]}'

See the official Claude Code MCP documentation for more details.

For Cursor

There are two ways to add an MCP server to Cursor. The most common way is to add the server globally in the ~/.cursor/mcp.json file so that it is available in all of your projects.

If you only need the server in a single project, you can add it to the project instead by creating or adding it to the .cursor/mcp.json file.

Adding an MCP server to Cursor globally

To add a global MCP server go to Cursor Settings > Tools & Integrations and click "New MCP Server".

When you click that button the ~/.cursor/mcp.json file will be opened and you can add your server like this:

{
    "mcpServers": {
        "echarts-mcp": {
            "command": "npx",
            "args": [
                "echarts-mcp"
            ]
        }
    }
}

Adding an MCP server to a project

To add an MCP server to a project you can create a new .cursor/mcp.json file or add it to the existing one. This will look exactly the same as the global MCP server example above.

How to use the MCP server

Once the server is installed, you might need to head back to Settings > MCP and click the refresh button.

The Cursor agent will then be able to see the available tools the added MCP server has available and will call them when it needs to.

You can also explicitly ask the agent to use the tool by mentioning the tool name and describing what the function does.

For Claude Desktop

To add this MCP server to Claude Desktop:

1. Find your configuration file:

• macOS: ~/Library/Application Support/Claude/claude_desktop_config.json
• Windows: %APPDATA%\Claude\claude_desktop_config.json
• Linux: ~/.config/Claude/claude_desktop_config.json

2. Add this to your configuration file:

{
    "mcpServers": {
        "echarts-mcp": {
            "command": "npx",
            "args": [
                "echarts-mcp"
            ]
        }
    }
}

3. Restart Claude Desktop for the changes to take effect
