MATLAB MCP Core Server

by matlab ↗

Run MATLAB from a conversation — evaluate a snippet, execute a script, run its tests, and lint it before any of that.

Physical Sciences & Scientific Computing✓ Official source
Summary
MathWorks' own server, so the code runs in real MATLAB rather than an approximation of it.

The useful pairing is the linter and the runner: `check_matlab_code` reads a script for style, deprecated calls and likely errors without executing it, which is the cheap check to make before `run_matlab_file` starts a session. It can also attach to a MATLAB you already have open, so the variables in your workspace stay where they are.

What it is

MathWorks' own MCP server for MATLAB. It starts MATLAB, or attaches to a session you already have open, runs the code you give it and returns the output. Five tools and two coding-standard resources.

What you get
  • `evaluate_matlab_code` — run a string of MATLAB with your project directory as the working folder, and read the real output
  • `run_matlab_file` — execute a `.m` script by absolute path
  • `run_matlab_test_file` — run a unit-test file written to MATLAB's testing framework and get the full results
  • `check_matlab_code` — static analysis on a script: style, likely errors, deprecated functions, performance and best-practice violations. Read-only, and the file is not modified
  • `detect_matlab_toolboxes` — which MATLAB and which toolboxes are installed, with version numbers
  • Two resources an assistant can read before it writes anything: `matlab_coding_guidelines` for naming, formatting, commenting and error handling, and `plain_text_live_code_guidelines` for version-controllable live scripts
Requirements

MATLAB R2021a or later, installed and on the system PATH — the server supports releases from the past five years. No account or key beyond your own MATLAB licence. Download the release binary for Windows, Linux or macOS (or build it with `go install`), then register it over stdio; Claude Desktop takes the `matlab-mcp-server.mcpb` bundle instead. `--matlab-root` picks which MATLAB to start, `--matlab-session-mode=existing` attaches to a session already shared with `shareMATLABSession()`, and `--matlab-display-mode=nodesktop` keeps the desktop closed. Every flag also works as an environment variable prefixed `MW_MCP_SERVER_`. Anonymised usage data is collected by default and `--disable-telemetry=true` turns it off.

Setup effort

One command — claude mcp add --transport stdio matlab -- /fullpath/to/matlab-mcp-server-binary
