Sequential Thinking MCP Server

A Model Context Protocol (MCP) server that helps break down complex problems into clear, sequential steps. This tool enhances structured problem-solving by managing thought sequences, allowing revisions, and supporting multiple solution paths.

Features

• 🧠 Sequential Problem Solving: Break down complex problems step-by-step
• 📊 Progress Tracking: Monitor thought sequences and branches

Prerequisites

• Python 3.11 or higher
• UV package manager (Install Guide)

Claude Desktop Integration

Add to your Claude Desktop configuration (%APPDATA%\Claude\claude_desktop_config.json on Windows):

{
  "mcpServers": {
    "sequential-thinking": {
      "command": "uv",
      "args": [
        "--directory",
        "C:\\path\\to\\your\\mcp-sequential-thinking\\mcp_sequential_thinking",
        "run",
        "server.py"
      ]
    }
  }
}

Development

Test the server manually:

cd mcp_sequential_thinking
uv run server.py

Troubleshooting

Common issues:

• Server Connection Issues
  • Verify paths in claude_desktop_config.json
  • Check Claude Desktop logs: %APPDATA%\Claude\logs
  • Test manual server start
