Does this stop you from using Cursor

Sometimes - I can sometimes use Cursor

I have lots of problems using MCP on windows. Similar issue - works on command line but not. In the end I have given up with MCP, often can get similar from command line tools

You should post your .json though

[casear (C4)]

My .json is very simple.

It seems that curosr doesn’t have enough permission to do MCP command. but I already check all permission, it should be ok.

The same thing happening to me, too. It seems light you’re not even using Smithery.ai as a middle man to connect to mcp servers. You’re directly connecting to mcp servers and it’s still not working? I thought it was smithery.ai’s server problem…

I guess it’s Cursor’s fault then?

I have same problem. Use windows + wsl.

Hey, can you check the logs? To do this, open the Output panel by going to the View -> Output menu, and in the dropdown menu, select the MCP Logs.

Hi, for npx on windows use : cmd /c npx or cmd /k npx.
