Think Strategies MCP Server

🧠 Think Strategies

10 Reasoning Strategies for Structured Problem-Solving

Overview

An MCP server implementation that provides a tool for dynamic and reflective problem-solving through structured thinking processes. Choose from 10 different reasoning strategies:

• 🔄 Linear - Flexible thinking with revisions and branches
• 🔗 Chain of Thought - Sequential step-by-step reasoning
• 🎯 React - Reasoning combined with actions and observations
• 📋 ReWOO - Plan-execute pattern with parallel tool usage
• 📝 Scratchpad - Iterative calculations with state tracking
• ❓ Self-Ask - Decompose into sub-questions and answers
• 🔍 Self-Consistency - Multiple reasoning paths to consensus
• 🔭 Step-Back - Abstract principles before specific application
• 🌳 Tree of Thoughts - Explore and evaluate multiple branches
• ⚖️ Trilemma - Balance three competing objectives through satisficing

Architecture

The think-strategies server uses a consolidated 3-tool architecture designed for optimal balance between simplicity and power:

2. think-tools (Action-Based Utilities)

Consolidated utilities with action-based routing.

Parameters (6):

Usage

When to Use Think-Strategies

The think-strategies server is designed for:

• Complex Problem-Solving: Break down multi-step challenges into manageable pieces
• Strategic Analysis: Choose the optimal reasoning approach for your specific problem type
• Iterative Refinement: Revise and improve your thinking as understanding deepens
• Alternative Exploration: Branch into different solution paths and compare approaches
• Tool Integration: Combine reasoning with real tool execution (think\u2192act\u2192reflect)
• Session Continuity: Resume and build upon previous thinking sessions

Strategy Selection Guide

• Linear/Chain of Thought: Step-by-step reasoning for straightforward problems
• ReAct: When you need to gather information or execute actions during reasoning
• ReWOO: For parallel tool usage and plan-execute workflows
• Tree of Thoughts: When exploring multiple solution branches is valuable
• Trilemma: For balancing three competing objectives through satisficing
• Self-Ask: Break complex questions into simpler sub-questions
• Step-Back: When you need to establish principles before diving into specifics

Installation

Prerequisites

• Node.js (v14 or higher) and npm (v6 or higher) OR
• Docker

Quick Start with npx (Easiest)

You can run the server directly using npx without cloning or installing:

# Run from npm registry (after publishing)
npx think-strategies

# Or run directly from GitHub
npx github:aaronsb/think-strategies

Setup with Node.js

1. Clone the repository:

git clone https://github.com/aaronsb/think-strategies.git
cd think-strategies

2. Install dependencies:

npm install

3. Make the server executable:

chmod +x index.js

4. Run the server:

node index.js

Setup with Docker

Using Pre-built Image (Recommended)

Pull and run the latest image from GitHub Container Registry:

docker run --rm -i ghcr.io/aaronsb/think-strategies:latest

Building Locally

1. Clone the repository:

git clone https://github.com/aaronsb/think-strategies.git
cd think-strategies

2. Build the Docker image:

./scripts/build-local.sh

3. Run the Docker container:

./scripts/run-local.sh

This will run the server with the correct permissions, ensuring that any files created are owned by the current user, not root.

Development

To contribute to the project:

1. Fork the repository on GitHub
2. Clone your fork locally
3. Add the upstream repository:

git remote add upstream https://github.com/aaronsb/think-strategies.git
