Add this to the mcpServers object in your client's config file, then restart the client.

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

VS Code uses a different key — show that config

Identical entry, filed under servers rather than mcpServers. Put it in .vscode/mcp.json for one workspace.

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

Before it will answer
