OriginPro MCP Server

A Model Context Protocol (MCP) server for controlling OriginLab OriginPro — the scientific graphing and data analysis software. This allows AI assistants like Claude to create publication-quality graphs, perform data analysis, and automate OriginPro workflows.

Windows only. OriginPro 2021+ and the originpro Python package (COM-based) are required.

Features

• Project management — create, open, save Origin projects (.OPJU/.OPJ)
• Data import — set worksheet data directly or import CSV/TXT files
• 16+ plot types — line, scatter, line+symbol, column, bar, area, stacked, pie, histogram, box, 3D, contour, heatmap, waterfall
• Plot customization — colors, symbol types, line widths, axis labels, legends (including CJK text)
• Statistical analysis — linear regression, descriptive statistics
• Graph export — PNG, JPG, TIFF, BMP, SVG, PDF, EPS
• LabTalk scripting — execute arbitrary Origin LabTalk scripts for advanced operations

Prerequisites

1. OriginPro 2021+ installed on Windows
2. Python 3.10+
3. Install dependencies:

   pip install -r requirements.txt
   

Setup

Claude Code

Add to your Claude Code MCP config (~/.claude/mcp.json):

{
  "mcpServers": {
    "originpro": {
      "command": "python",
      "args": ["C:\\path\\to\\originpro-mcp\\originpro_mcp_server.py"]
    }
  }
}

Other MCP Clients

Run the server directly:

python originpro_mcp_server.py

How It Works

The MCP server uses the originpro Python package, which communicates with OriginPro via COM automation (Windows only). The server exposes OriginPro's functionality through the Model Context Protocol, allowing AI assistants to control OriginPro programmatically.
