Sequential Thinking MCP Server

An MCP server implementation that provides a tool for dynamic and reflective problem-solving through a structured thinking process.

Install

npx -y @modelcontextprotocol/server-sequential-thinking

Example config (Cursor / Claude Desktop)

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

VS Code uses "servers" instead of "mcpServers" (why). On Windows, wrap npx with cmd /c (fix).
