matlab-mcp-tools

Overview

This MCP server enables interaction with MATLAB through a comprehensive set of tools. It allows executing MATLAB scripts or sections, managing workspace variables, and analyzing figures. The server supports various execution modes (complete scripts, sections by index/title/line range) and provides workspace introspection capabilities. It can extract plot data, generate analysis prompts, and prepare figures for LLM-based analysis. The implementation includes automatic installation and configuration support for Claude Code and Cursor.

FAQ

What MATLAB versions are supported?

The server supports MATLAB R2023x and later versions. Python version is automatically matched to your MATLAB version (e.g., MATLAB R2024b uses Python 3.11).

How can I execute specific sections of a MATLAB script?

Use the `execute_section_by_index` tool to execute sections by their 0-based index, or `execute_section_by_title` with partial title matching. You can also use `execute_section` to specify a line range.

Can I retrieve plot data programmatically?

Yes, use the `get_plot_data` tool to extract raw x/y/z data from plot lines, or `get_figure_metadata` to get axes information, labels, and legends.
