Error in linking Claude with MATLAB using MCP server

I tried to link my claude with MATLAB using the MCP server. However there is some issue in the connection. I am receing these error messges in claude:

Could not attach to MCP server MATLAB

MCP MATLAB: Server disconnected.

Unable to connect to extension server. Please try disabling and re-enabling the extension.

I downloaded the MCP server from github and added it to the extensions in claude. I tried both - mcpb version (matlab-mcp-core-server.mcpb) and the win64 application (matlab-mcp-core-server-win64) method to try adding the extension. Still some command or settings is blocking the process.

I have also attached the screenshots of the extensions and developer tabs of claude for reference.

Is there any other setting or procedure I am missing? What might be the error here...

Same problem! Mathworks and Anthropic should do something about it.

Similar problem found. Under the same setup, Claude desktop is the only application that fails to use Matlab MCP server. I believe the extension is correctly configured for Claude, and Claude recognizes it when trying to bridge Matlab software. But the server itself fails to request that, and Claude just waits for a response until timeout. This does not happen to any other agent after being tested, such as Codex or Opencode. It is a UNIQUE problem for Claude using Matlab MCP server. Waiting for a solution.

Hi @Szymon, @Yifan,

In the v0.8 MCPB release we added an optional Log Folder directory setting. Could you try setting this to a short, existing folder path on your local machine that you know is writable?

This can help if the issue is related to filesystem access or path length. If the problem persists, that folder should contain log files which may help with further debugging. Additional support is available via GitHub here:

Thanks!

Based on the details you’ve shared, it looks like the MCP Core Server is not successfully attaching to Claude, even though the extension itself has been added correctly. At this point, this does not appear to be a simple configuration issue on your end and may require review by the MCP Core Server team, especially given the repeated “Server disconnected” errors across both the ".mcpb" and "Win64" setups.

For setup‑related questions or connection troubleshooting, you can reach the MCP Core Server team directly using the “Have Questions?” button at the bottom of this page:

If you believe this may be a bug or an unsupported interaction with Claude’s extension framework, it would be best to report it on the project’s GitHub repository with the error messages and screenshots you mentioned:

https://github.com/matlab/matlab-mcp-core-server/issues

That should help ensure the issue is reviewed by the developers who maintain the MCP server and can advise on whether additional settings, permissions, or current limitations are involved.
