🧠 A detailed tool for dynamic and reflective problem-solving through sequential thinking. This tool helps you analyze problems through a flexible thinking process that can adapt and evolve. Each thought can build on, question, or revise previous insights as understanding deepens. 📋 KEY PARAMETERS: - thought: Your current reasoning step (required) - thought_number: Current number in sequence (required) - total_thoughts: Estimated final count (required, can adjust as needed) - next_thought_needed: Set to FALSE ONLY when completely done (required) - branch_from_thought + branch_id: When exploring alternative approaches (🌿) - is_revision + revises_thought: When correcting earlier thinking (🔄) ✅ CRITICAL CHECKLIST (review every 3 thoughts): 1. Need to explore alternatives? → Use BRANCH (🌿) with branch_from_thought + branch_id 2. Need to correct earlier thinking? → Use REVISION (🔄) with is_revision + revises_thought 3. Scope changed? → Adjust total_thoughts up or down as needed 4. Only set next_thought_needed = false when you have a complete, verified solution 💡 BEST PRACTICES: - Start with an initial estimate of total_thoughts, but adjust as you go - Don't hesitate to revise earlier conclusions when new insights emerge - Use branching to explore multiple approaches to the same problem - Express uncertainty when present - Ignore information that is irrelevant to the current step - End with a clear, validated conclusion before setting next_thought_needed = false ✍️ End each thought by asking: "What am I missing or need to reconsider?"

Overview

What is Code Reasoning MCP Server?

A Model Context Protocol (MCP) server that enhances Claude's ability to solve complex programming tasks through structured, step-by-step thinking. It integrates with Claude Desktop and VS Code, providing a systematic approach to coding challenges.

How to use Code Reasoning MCP Server?

Install by adding the server configuration (npx -y @mettamatt/code-reasoning) to your Claude Desktop or VS Code MCP settings. To trigger reasoning, append "Use sequential thinking to reason about this." to your chat message, or use ready-made prompt templates via the "+" icon or /help command. Optional command-line flags include --debug for detailed logging and --help for help.
