A Model Context Protocol (MCP) server that provides tools for developing and running MATLAB files. This tool integrates with Cline and other MCP-compatible clients to provide interactive MATLAB development capabilities.

• Python 3.8+
• MATLAB with Python Engine installed

1. Execute MATLAB Scripts

   • Run complete MATLAB scripts
   • Execute individual script sections
   • Maintain workspace context between executions
   • Capture and display plots

2. Section-based Execution

   • Execute specific sections of MATLAB files
   • Support for cell mode (%% delimited sections)
   • Maintain workspace context between sections

1. Clone this repository:

git clone [repository-url]
cd matlab-mcp-tools

2. Create and activate a Conda environment:

conda create -n matlab-mcp python=3.8
conda activate matlab-mcp

3. Install the package and its dependencies:

pip install -e .

4. Install MATLAB Engine for Python:

# Navigate to MATLAB engine directory
cd /Applications/MATLAB_R2024b.app/extern/engines/python

# Install MATLAB engine
python setup.py install

5. Add MATLAB to system PATH:

export PATH="/Applications/MATLAB_R2024b.app/:$PATH"

1. Start the MCP server:

python -m matlab_mcp.server

You should see a startup message listing the available tools and confirming the server is running:

MATLAB MCP Server is running...
Available tools:
  - execute_script: Execute MATLAB code or script file
  - execute_script_section: Execute specific sections of a MATLAB script
  - get_script_sections: Get information about script sections
  - create_matlab_script: Create a new MATLAB script
  - get_workspace: Get current MATLAB workspace variables

Use the tools with Cline or other MCP-compatible clients.

2. Alternatively, configure Cline to use the MATLAB MCP server by adding to your Cline configuration:

{
  "mcpServers": {
    "matlab": {
      "command": "python",
      "args": ["-m", "matlab_mcp.server"],
      "env": {
        "PYTHONPATH": "/path/to/matlab/engine/installation"
      }
    }
  }
}

Hint: You can find the MATLAB engine installation path by running python -c "import matlab; print(matlab.__file__)".

3. Available Tools:

• execute_matlab_script

  {
    "script": "x = 1:10;\nplot(x, x.^2);",
    "isFile": false
  }

• execute_matlab_section

  {
    "filePath": "analysis.m",
    "sectionStart": 1,
    "sectionEnd": 10
  }

This example demonstrates running a complete MATLAB script that generates a plot:

% test_plot.m
x = linspace(0, 2*pi, 100);
y = sin(x);

% Create a figure with some styling
figure;
plot(x, y, 'LineWidth', 2);
title('Sine Wave');
xlabel('x');
ylabel('sin(x)');
grid on;

% Add some annotations
text(pi, 0, '\leftarrow \pi', 'FontSize', 12);

To execute this script using the MCP tool:

{
    "script": "test_plot.m",
    "isFile": true
}

The tool will execute the script and capture the generated plot, saving it to the output directory.

This example shows how to execute specific sections of a MATLAB script:

%% Section 1: Data Generation
% Generate sample data
x = linspace(0, 10, 100);
y = sin(x);

fprintf('Generated %d data points\n', length(x));

%% Section 2: Basic Statistics
% Calculate basic statistics
mean_y = mean(y);
std_y = std(y);
max_y = max(y);
min_y = min(y);

fprintf('Statistics:\n');
fprintf('Mean: %.4f\n', mean_y);
fprintf('Std Dev: %.4f\n', std_y);
fprintf('Max: %.4f\n', max_y);
fprintf('Min: %.4f\n', min_y);

%% Section 3: Plotting
% Create visualization
figure('Position', [100, 100, 800, 400]);

subplot(1, 2, 1);
plot(x, y, 'b-', 'LineWidth', 2);
title('Signal');
xlabel('x');
ylabel('y');
grid on;

subplot(1, 2, 2);
histogram(y, 20);
title('Distribution');
xlabel('Value');
ylabel('Count');
grid on;

sgtitle('Signal Analysis');

To execute specific sections:

{
    "filePath": "section_test.m",
    "sectionStart": 1,
    "sectionEnd": 2
}

This will run sections 1 and 2, generating the data and calculating statistics. The output will include:

Generated 100 data points
Statistics:
Mean: 0.0000
Std Dev: 0.7071
Max: 1.0000
Min: -1.0000

The tool creates matlab_output and test_output directories to store:

• Plot images generated during script execution
• Other temporary files

• Script execution errors are captured and returned with detailed error messages
• Workspace state is preserved even after errors
