VS Code Sequential Thinking sequentialthinking

Add Sequential Thinking to VS Code

1. 01

   Open .vscode/mcp.json and merge this in. Keep any servers already there.

{
  "servers": {
    "server-sequential-thinking": {
      "type": "stdio",
      "command": "npx",
      "args": [
        "-y",
        "@modelcontextprotocol/server-sequential-thinking"
      ]
    }
  }
}

2. 02

   Save the file and restart VS Code.

3. 03

   Ask for something sequentialthinking does. VS Code lists the server's tools on connect and calls sequentialthinking itself — you do not invoke it by name.

4. 04

   If nothing happens, check the server is running and that Sequential Thinking's identifier in your config matches the one above exactly.

Requires agent mode. MCP: Open User Configuration puts the same block in every workspace. VS Code docs
