Enhanced Sequential Thinking MCP Server

This project implements an advanced Sequential Thinking server using the Model Context Protocol (MCP). It provides a structured and flexible approach to problem-solving and decision-making through a series of thought steps, incorporating stages, scoring, and tagging.

Features

• Structured Problem Solving: Break down complex problems into defined stages
• Progress Tracking: Monitor thought sequences, branches, and revisions
• Thought Categorization: Tag and score thoughts for better organization
• Dynamic Adaptation: Adjust the thinking process as new insights emerge
• Summary Generation: Get an overview of the entire thinking process

Prerequisites

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

Quick Start

1. Set Up Project

   # Create and activate virtual environment
   uv venv
   .venvScriptsactivate  # Windows
   source .venv/bin/activate  # Unix
   
   # Install package and dependencies
   uv pip install -e .
   

2. Run the Server

   cd mcp_sequential_thinking
   uv run server.py
   

Claude Desktop Integration

Add to your Claude Desktop configuration (%APPDATA%Claudeclaude_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"
      ]
    }
  }
}

API

The server exposes two main tools:

1. sequential_thinking

This tool processes individual thoughts in the sequential thinking process.

Parameters:

• thought (str): The content of the current thought
• thought_number (int): The sequence number of the current thought
• total_thoughts (int): The total number of thoughts expected
• next_thought_needed (bool): Whether another thought is needed
• stage (str): The current stage of thinking (Problem Definition, Analysis, Ideation, Evaluation, Conclusion)
• is_revision (bool, optional): Whether this revises previous thinking
• revises_thought (int, optional): Which thought is being reconsidered
• branch_from_thought (int, optional): Branching point thought number
• branch_id (str, optional): Branch identifier
• needs_more_thoughts (bool, optional): If more thoughts are needed
• score (float, optional): Score for the thought (0.0 to 1.0)
• tags (List[str], optional): List of tags for categorizing the thought

2. get_thinking_summary

This tool generates a summary of the entire thinking process.

Troubleshooting

Common issues:

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