offline install with newest version of agenticToolkitInstaller fails to install MATLAB MCP Server Toolbox

[j-hap]

Use Case

I tried to run the agentic toolkit installer with all local resources for company wide offline installations. for my prove of concept, I cloned the matk and satk as well as the latest version of the mcp server.
I cut the internet connection to prevent the installer from downloading anything.
the installer told me, where it expected the mcp server executable, and i put it there and called

setupAgenticToolkit("install", Toolkit=["matlab", "simulink"], Source=["matlab=some/path/", "simulink=some/other/path/"]);

the output of that command was:

Warning: MATLAB MCP Server Toolbox is not installed and cannot be downloaded
in offline mode. Install manually:
  1. Download the .mltbx from https://github.com/matlab/matlab-mcp-core-server/releases
  2. In MATLAB, run: matlab.addons.toolbox.installToolbox("<path-to-file>.mltbx") 
> In [setupAgenticToolkit](matlab:matlab.lang.internal.introspective.errorDocCallback('setupAgenticToolkit'))
In [setupAgenticToolkit](matlab:matlab.lang.internal.introspective.errorDocCallback('setupAgenticToolkit'))
In [setupAgenticToolkit](matlab:matlab.lang.internal.introspective.errorDocCallback('setupAgenticToolkit'))
In ...

Relevant Skill or MCP Tool

matlab-mcp-server

Proposed Behavior

the mcp server exe contains a packaged mcp server toolbox, which can be installed via the --setup-matlab flag. The agentic toolkit installer should use that to install the toolbox instead of expecting the mltbx file for the mcp server toolbox.

Current Workaround

workaround would be to put an offline version of the mltbx somewhere as well, I don't know where the installer expects it though.

This should be addressed in the latest release of SATK (2026.07.02). Please take a look at let us know if you encounter any further issues.

Thanks!

The issue still exists for me. I wrote a small wrapper around the install process. It copies the mcp server binary from a local resource (for a bunch of enterprise users, that shall not download individually). afterwards it installs the agentic toolkit installer and starts it with local sources. It sees the existing mcp server binary, but complains about the missing mcp server toolbox:

  Plan:
    - Download and install the MATLAB MCP Server
    - Install the MATLAB MCP Server Toolbox (enables agents to connect to a running MATLAB session)
    - Install the MATLAB Agentic Toolkit from local directory at matlab-agentic-toolkit
    - Install the Simulink Agentic Toolkit from local directory at simulink-agentic-toolkit

  Proceed? [Y/n]: y
  MCP server binary already installed (v0.11.1), skipping update check.

The toolkit installer should use the mcp server binary with the --setup-matlab flag to install the toolbox, that is packaged with the binary:

>> !matlab-mcp-server-windows-x64.exe --setup-matlab
Successfully setup MATLAB.

which installs the toolbox, that is embedded in the server binary, see (internal\adaptors\matlabmanager\addonmanager\installationsteps\assets\matlab\upload_mltbx.m)

unfortunately, when called via system() or ! the current session does not register the new toolbox right away, a new session does. there is probably some sort of discovery call that I do not know about to make sure that the current session sees the new toolbox.

Thanks for following up on this and providing the steps you took to try to work around the issue.
We will continue to investigate.

Thanks!
