---

14 structured MCP tools for loading models, inspecting blocks, tweaking parameters, running simulations, and capturing figures as images. Every operation is a typed tool call with validated inputs — no arbitrary code execution.

Why this over a general MATLAB MCP server?

General-purpose MATLAB servers pass arbitrary code strings to eval(). That works until the AI hallucinates a function name, forgets a semicolon, or writes a plot() call that blocks forever. This server exposes Simulink operations as discrete, validated tools — the AI picks the right tool and fills in typed parameters instead of generating free-text MATLAB code.

Install

1. MATLAB Engine for Python

The MATLAB Engine ships with every MATLAB installation:

cd /extern/engines/python
pip install .

`` is typically:

• macOS: /Applications/MATLAB_R2024b.app
• Linux: /usr/local/MATLAB/R2024b
• Windows: C:\Program Files\MATLAB\R2024b

2. simulink-mcp

pip install simulink-mcp

Or from source:

git clone https://github.com/sohumsuthar/simulink-mcp.git
cd simulink-mcp
pip install .

3. Verify

python -c "import matlab.engine; print('OK')"

Configuration

Claude Code

claude mcp add simulink -- python -m simulink_mcp

Claude Desktop

Add to your claude_desktop_config.json:

{
  "mcpServers": {
    "simulink": {
      "command": "python",
      "args": ["-m", "simulink_mcp"],
      "env": {
        "SIMULINK_MCP_WORKDIR": "/path/to/your/models"
      }
    }
  }
}

Then ask Claude to load a model and it’ll take it from there.
