MATLAB Simulink Plugin

June 22, 2026 ยท View on GitHub

Public Codex plugin for MATLAB MCP Server and Simulink modeling, simulation, baseline testing, and profiler analysis workflows.

This repository is a standalone public Codex plugin package. It contains the plugin manifest, MCP launcher, workflow skills, and lightweight validation scripts. It does not include local software installations, private databases, drawings, simulation artifacts, or machine-specific configuration.

Requirements

  • MATLAB installed locally
  • MATLAB MCP Server v0.11.0 or newer
  • MATLAB MCP executable configured with MATLAB_MCP_EXE or MATLAB_MCP_HOME
  • Optional MATLAB_ROOT and MATLAB_INITIAL_WORKING_FOLDER

Environment

Configure only the variables that apply to your machine:

$env:MATLAB_MCP_EXE = "<path-to-matlab-mcp-server-windows-x64.exe>"
# Or point to the folder containing the executable:
$env:MATLAB_MCP_HOME = "<path-to-matlab-mcp-server-folder>"
$env:MATLAB_ROOT = "<path-to-matlab-root>"
$env:MATLAB_INITIAL_WORKING_FOLDER = "<optional-working-folder>"
$env:MATLAB_DISPLAY_MODE = "nodesktop"

MATLAB MCP Server v0.11.0 renamed the Windows binary from matlab-mcp-core-server-win64.exe to matlab-mcp-server-windows-x64.exe. After upgrading, install or update MATLAB MCP Server Toolbox once:

& $env:MATLAB_MCP_EXE --setup-matlab "--matlab-root=$env:MATLAB_ROOT"

The launcher prefers MATLAB_MCP_EXE, can discover the renamed executable from MATLAB_MCP_HOME, and retains compatibility with the legacy filename.

Codex Plugin Layout

  • .codex-plugin/plugin.json: plugin manifest
  • .mcp.json: MCP server launch definition
  • skills/: Codex skills shipped by this plugin
  • scripts/: MCP launcher and repository validation scripts

Local Checks

Run structural and privacy checks before sharing changes:

.\scripts\check-plugin.ps1
.\scripts\check-repo-privacy.ps1

Run the launcher smoke check after configuring local environment variables:

.\scripts\start-matlab-mcp.ps1 -Check

Notes For Contributors

  • Do not commit real secrets, local absolute paths, private databases, binary project files, logs, caches, DWG files, Simulink models, or generated simulation outputs.
  • Keep machine-specific configuration in environment variables.
  • Keep reusable workflow knowledge in skills/ and lightweight scripts in scripts/.
