MATLAB MCP Server
This Model Context Protocol (MCP) server provides integration with MATLAB, allowing you to create and execute MATLAB scripts and functions through Claude or other MCP clients.
Setup Requirements
- Python 3.11 (Python 3.13 and 3.12 are not currently supported by MATLAB Engine)
- MATLAB R2024a (or compatible version)
- uv package manager
Installation
- Create and set up the Python environment:
- Install MATLAB Engine
The MATLAB Engine will be installed automatically when the server first runs, using the MATLAB installation specified in the
MATLAB_PATH
environment variable.
Directory Structure
matlab_server.py
: The main MCP server implementationmatlab_scripts/
: Directory where all MATLAB scripts and functions are saved (created automatically)pyproject.toml
: Python project configuration.python-version
: Specifies Python version for uv
Claude Desktop Integration
- Open your Claude Desktop configuration:
- Add the MATLAB server configuration:
Make sure to:
- Replace
/absolute/path/to/matlab-mcp
with the actual path to your project directory - Verify the
MATLAB_PATH
points to your MATLAB installation - Use absolute paths (not relative)
Features
The server provides several tools:
create_matlab_script
: Create a new MATLAB script file- Scripts are saved in the
matlab_scripts
directory - File names must be valid MATLAB identifiers
- Scripts are saved in the
create_matlab_function
: Create a new MATLAB function file- Functions are saved in the
matlab_scripts
directory - Must include valid function definition
- Functions are saved in the
execute_matlab_script
: Run a MATLAB script and get results- Returns output text, generated figures, and workspace variables
- Can pass arguments to scripts
call_matlab_function
: Call a MATLAB function with arguments- Returns function output and any generated figures
Testing
You can test the server using the MCP Inspector:
Example test script:
Script Storage
- All MATLAB scripts and functions are saved in the
matlab_scripts
directory - This directory is created automatically when the server starts
- Files are named
<script_name>.m
or<function_name>.m
- The directory is in the same location as
matlab_server.py
Environment Variables
MATLAB_PATH
: Path to your MATLAB installation- Default:
/Applications/MATLAB_R2024a.app
- Set in Claude Desktop config or when running directly
- Default:
Troubleshooting
- MATLAB Engine Installation Fails
- Verify MATLAB_PATH is correct
- Try installing engine manually:
- Python Version Issues
- Make sure you're using Python 3.11
- Check with:
python --version
- Use
uv python pin 3.11
if needed
- Script Execution Errors
- Check the
matlab_scripts
directory exists - Verify script syntax is valid
- Look for error messages in MATLAB output
- Check the
Updates and Maintenance
- Keep your MATLAB installation updated
- Update Python packages as needed:
uv pip install --upgrade mcp[cli]
- Check MATLAB engine compatibility when updating Python
This server cannot be installed
local-only server
The server can only run on the client's local machine because it depends on local resources.
Allows interaction with MATLAB by creating and executing scripts and functions through Claude or other MCP clients, supporting script management and execution result retrieval with environment configuration capabilities.
