Quickchart-MCP-Server: What is it?

Quickchart-MCP-Server is a TypeScript-based Model Context Protocol (MCP) server that integrates with QuickChart.io to provide robust chart generation capabilities. It allows users to create a wide array of chart images by converting Chart.js configurations into QuickChart URLs or downloadable images.

How to Use Quickchart-MCP-Server?

To use Quickchart-MCP-Server, you interact with its provided tools, primarily generate_chart and download_chart. You supply chart configurations in the Chart.js format, specifying chart type, data, labels, and styling. The server then processes this configuration to either return a URL to the generated chart or save the chart image to a local file.

Chart Configuration Example:

{
  "type": "bar",
  "data": {
    "labels": ["January", "February", "March"],
    "datasets": [{
      "label": "Sales",
      "data": [65, 59, 80],
      "backgroundColor": "rgb(75, 192, 192)"
    }]
  },
  "options": {
    "title": {
      "display": true,
      "text": "Monthly Sales"
    }
  }
}

Installation:

You can install the server via npm:

npm install @gongrzhe/quickchart-mcp-server

Or, for Claude Desktop users, via Smithery:

npx -y @smithery/cli install @gongrzhe/quickchart-mcp-server --client claude

After installation, configure your Claude Desktop claude_desktop_config.json to include the server, specifying the command to run it.
