Here are the steps.

Make sure you have node installed on windows.

node -v

Install the NPM package for the MCP tool globally on windows

npm install -g @modelcontextprotocol/server-sequential-thinking

Find the root where your global windows NPM packages are installed

npm root -g

Work out the actual node executable

In this case for me it was:

C:\Program Files\nodejs\node_modules\@modelcontextprotocol\server-sequential-thinking\dist\index.js

Set up the cursor MCP config as follows

{
  "mcpServers": {
    "sequential-thinking": {
      "command": "node 'C:\\Program Files\\nodejs\\node_modules\\@modelcontextprotocol\\server-sequential-thinking\\dist\\index.js'"
    }
  }
}

Check that it's enabled.

Test it

Update

Next day, sequential-thinking didn't work, and I couldn't get the playwright MCP working through this method.

So I playaround a bit, and got this, which also means you install the packages globally on windows.

{
  "mcpServers": {
    "sequential-thinking": {
      "command": "cmd",
      "args": [
        "/c",
        "npx",
        "-y",
        "@modelcontextprotocol/server-sequential-thinking"
      ]
    },

    "browser-tool-mcp": {
      "command": "cmd",
      "args": [
        "/c",
        "npx",
        "-y",
        "@playwright/mcp"
      ]
    }
  }
}
