Hey, check out this thread, there are solutions that might help:

MCP Servers No tools found

I added an MCP service in Cursor, which is a very useful feature. However, I encountered an issue during use: when the MCP tool times out, the MCP in Cursor stops working. It requires restarting Cursor to function properly again. p.s. version：0.45.11 [image]

Running on Mac, I tried some MCP Servers with curious results:

• npx -y @modelcontextprotocol/server-filesystem ... No tools found

• npx -y @modelcontextprotocol/server-sequential-thinking OK, but the server entry disappears after some refresh about a minute later

Very strange. Of course, all MCP Servers are working with Claude Desktop and Cline…

On my windows, I tried npx -y @modelcontextprotocol/server-sequential-thinking and didn’t work.
Then I try node "C:\Program Files\nodejs\node_modules\@modelcontextprotocol\server-sequential-thinking\dist\index.js"
It shows green light then flashing a few times, and becomes red again.

I think it’s because of windows user running the command with Powershell.
In my test, the execution in Powershell directly seem to get into some issues.

But In the end, I’m able to run it directly with node like this

Hey, MCP support has had some significant improvements in V0.46. So I’d wait until you get that update and give things a try then!

in 4.6 I can’t seem to get MCP working no matter what I try

• npx -y @server/tool
• pointing to a wrapper (that works fine in terminal) /location/mcp.sh
• trying to use env vars env TOKEN=my-token @server/tool
