For this, I have a mac, and it works for me.

Wondering a couple of things, but I think yours is a separate issue. Try to restart your mac.

Try to make sure you have the right mcp config as per instructions

Can confirm this issue has occurred for me on a Mac.

It was working fine.

Then after another task, I noticed it was not updating the tasks.json file. The response after the tool call was a connection error.

I opened up the MCP server and it reported "Client Closed".

Worked after a refresh.

For the windows, we need to improve documentation, its actually slightly different.

Has this been done yet? Still getting client closed errors with Windows 11. Unusable with the current documentation

Output Log for Cursor says the following:

I'm gonna set up on my windows PC and see what's going on

gags

[freemchr]

Sounds good. I tried with the manual local install too with the npm, and came up with numerous errors. Just can't get it to work at all.

[freemchr]

How did you go? @eyaltoledano

I've gotten it working with cursor on one machine but cant on another, both running Win11 both running the latest stable build. Follow the usual instructions (setup in mcp.json, add in keys, restart cursor/windsurf/augment/etc. And I'm still getting the same result across each IDE/agent. All my other MCPs seem to run just fine. Tried to run through it the manual way (npx install -g...) but still had no luck.

[freemchr]

Yes same for me, other MCPs work perfectly.
