How to connect MCP Server via Cursor?

Hi. I’m new with Cursor! I saw this new feature that everyone is talking about. So I wanna try it. Unfortunately, my English is not so well. So I wanna ask if everyone can teach me how to use this feature?


Trying make it work by following steps of tutorial. But something still went missing…

Hello,
Your commands look right. I use the same commands and have had success:

My first suggestion would be to close Cursor and reopen it, and see if that fixes it.

If that doesn’t work, you could try to configure it for the Claude app, and see if that is successful or not. If it’s unsuccessful, it might indicate a network issue? (VPN maybe?)

Assuming you’re on a Mac.

Download Claude Desktop: Download Claude
Open the App > Claude > Settings:

Developer > Edit Config:

This should create a file ~/Library/Application Support/Claude/claude_desktop_config.json. Add your MCP configuration here. In your case, it should be this:

{
  "mcpServers": {
    "Sequential Thinking": {
      "command": "npx",
      "args": ["-y", "@modelcontextprotocol/server-sequential-thinking"]
    },
    "Web Research": {
      "command": "npx",
      "args": ["-y", "@mzxrai/mcp-webresearch@latest"]
    }
  }
}

Save the file, quit Claude and reopen, and you should see the tools there:

If neither Cursor nor Claude work, it sounds like it might be a network issue.
If Claude works but Cursor doesn’t, I really don’t know.

My best advice in playing with MCPs so far is to always close and reopen the program (be it Cursor or Claude).

I hope this helps.

I’ve test it with Claude now. It did shows MCP servers. And in chat area it shows 1 MCP tool is available. Only Cursor can’t do it I have no idea why.


Even though I have restarted Cursor and nothing still work.

I have the same problem.

I’m experiencing the same issue.

Hey, what happens if you enter these commands in the terminal? If that doesn’t work either, you might need a VPN.

It works in terminial. Both, in remoted SSH and my laptop.

Do you guys have a manager like nvm installed? try npm install -g @modelcontextprotocol/server-sequential-thinking . close and open cursor and retry. if doesn’t work try full path to npx . ie which npx to get full path and use full path in command /home/myname/.nvm/versions/node/v20.11.0/bin/npx -y @modelcontextprotocol/server-sequential-thinking see if that helps

It works when I initially set up a MCP - it opens up a terminal and runs the node program. However, it doesn’t run when I re open cursor and have to do it every time

Try this in the meantime while cursor fixes the issue: GitHub - daniel-lxs/mcp-starter

What does the thinking project (mcp server) do? I don’t really understand and I wonder

Full path of Node works for me!! Thank you.

If everyone wondering how to do it. Just find where your nodejs installed and find node_module, find the MCP you installed. And use full path to/dist/index.js

Yes, but then Cursor opens the terminal, and it is constantly open, which is a little ugly and very distracted, especially with Alt+Tab

Are you sure that it works? In the end, I was faced with the problem that when i set command node D:\Path\To\NodeModule\dist\index.js Cursor shows that everything is OK, but the error occurs when using the tool

Can you please elaborate on this (with pictures of what ultimately worked for you)?
Whoch OS are you on?

I don’t know if this is help but I use

node ...\\npm\\node_module\\@modelcontentprotocol\\server-sequential-thinking\\dist\\index.js

After you did this. It should pop up a terminal which is success.
I think you also need to install MCP server locally.

You should write tutorials…

Someone did. I just followed his instruction.
