Enhanced Sequential Thinking MCP Server

Custom Enhanced Version by new69toss

A Model Context Protocol (MCP) server that facilitates structured, progressive thinking through defined stages with enhanced capabilities for the AI Prompt Optimizer project. This tool helps break down complex problems into sequential thoughts, track the progression of your thinking process, and generate summaries.

Features

• Structured Thinking Framework: Organizes thoughts through standard cognitive stages (Problem Definition, Research, Analysis, Synthesis, Conclusion)

• Thought Tracking: Records and manages sequential thoughts with metadata

• Related Thought Analysis: Identifies connections between similar thoughts

• Progress Monitoring: Tracks your position in the overall thinking sequence

• Summary Generation: Creates concise overviews of the entire thought process

• Persistent Storage: Automatically saves your thinking sessions with thread-safety

• Data Import/Export: Share and reuse thinking sessions

• Extensible Architecture: Easily customize and extend functionality

• Robust Error Handling: Graceful handling of edge cases and corrupted data

• Type Safety: Comprehensive type annotations and validation

Prerequisites

• Python 3.10 or higher

• UV package manager (Install Guide)

Key Technologies

• Pydantic: For data validation and serialization

• Portalocker: For thread-safe file access

• FastMCP: For Model Context Protocol integration

• Rich: For enhanced console output

• PyYAML: For configuration management

Project Structure

Quick Start

1. Set Up Project

   # Create and activate virtual environment uv venv .venv\Scripts\activate # Windows source .venv/bin/activate # Unix # Install package and dependencies uv pip install -e . # For development with testing tools uv pip install -e ".[dev]" # For all optional dependencies uv pip install -e ".[all]"

2. Run the Server

   # Run directly uv run -m mcp_sequential_thinking.server # Or use the installed script mcp-sequential-thinking

3. Run Tests

   # Run all tests pytest # Run with coverage report pytest --cov=mcp_sequential_thinking

Claude Desktop Integration

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

Alternatively, if you've installed the package with pip install -e ., you can use:

You can also run it directly using uvx and skipping the installation step:

How It Works

The server maintains a history of thoughts and processes them through a structured workflow. Each thought is validated using Pydantic models, categorized into thinking stages, and stored with relevant metadata in a thread-safe storage system. The server automatically handles data persistence, backup creation, and provides tools for analyzing relationships between thoughts.

Usage Guide

The Sequential Thinking server exposes three main tools:

1. process_thought

Records and analyzes a new thought in your sequential thinking process.

Parameters:

• thought (string): The content of your thought

• thought_number (integer): Position in your sequence (e.g., 1 for first thought)

• total_thoughts (integer): Expected total thoughts in the sequence

• next_thought_needed (boolean): Whether more thoughts are needed after this one

• stage (string): The thinking stage - must be one of:

  • "Problem Definition"

  • "Research"

  • "Analysis"

  • "Synthesis"

  • "Conclusion"

• tags (list of strings, optional): Keywords or categories for your thought

• axioms_used (list of strings, optional): Principles or axioms applied in your thought

• assumptions_challenged (list of strings, optional): Assumptions your thought questions or challenges

Example:

2. generate_summary

Generates a summary of your entire thinking process.

Example output:

3. clear_history

Resets the thinking process by clearing all recorded thoughts.

Practical Applications

• Decision Making: Work through important decisions methodically

• Problem Solving: Break complex problems into manageable components

• Research Planning: Structure your research approach with clear stages

• Writing Organization: Develop ideas progressively before writing

• Project Analysis: Evaluate projects through defined analytical stages

Getting Started

With the proper MCP setup, simply use the process_thought tool to begin working through your thoughts in sequence. As you progress, you can get an overview with generate_summary and reset when needed with clear_history.

Customizing the Sequential Thinking Server
