mettamatt/code-reasoning is a Model Context Protocol (MCP) server, forked from the sequential-thinking project, engineered to significantly enhance the capabilities of large language models, particularly Claude, in tackling complex programming tasks. It provides a structured, step-by-step reasoning framework, enabling developers to leverage AI for more robust, traceable, and accurate code problem-solving and generation.

How It Works

This MCP server acts as an intermediary, integrating seamlessly with Claude Desktop and VS Code through simple JSON configuration updates. Its core mechanism involves intercepting user prompts and guiding the LLM through a deliberate, multi-stage thinking process. This includes breaking down intricate problems into manageable sub-tasks, exploring diverse solution avenues via "thought branching" to evaluate alternatives concurrently, and enabling iterative "thought revision" where earlier reasoning can be refined based on new insights. This structured approach aims to improve the depth, accuracy, and reliability of AI-generated code solutions by mimicking a methodical human problem-solving process.

Quick Start & Requirements

• Installation: Configure your Claude Desktop (claude_desktop_config.json for macOS, Windows, Linux) or VS Code (settings.json) by adding the code-reasoning MCP server configuration, specifying npx -y @mettamatt/code-reasoning as the command.
• Prerequisites: Requires Node.js and its package manager (npm/npx) to be installed.
• Documentation: Comprehensive guides covering usage examples, detailed configuration options, prompt customization, and testing utilities are available within the project's docs directory.

Highlighted Details

• Programming Focus: Explicitly optimized for complex coding challenges, debugging, and software development workflows.
• Structured Reasoning Engine: Implements a core engine for step-by-step problem decomposition and logical progression.
• Advanced AI Interaction: Supports sophisticated interaction patterns like thought branching (parallel exploration) and thought revision (iterative refinement).
• Safety & Control: Incorporates an automatic reasoning halt after 20 thought steps, acting as a safeguard against potential infinite loops or excessive computation.
• Pre-built Prompts: Comes with ready-to-use prompt templates designed for common development tasks, streamlining initial adoption.

Maintenance & Community

The project is identified as a fork of sequential-thinking, suggesting a lineage of development. However, the provided README does not detail specific core contributors, community channels (e.g., Discord, Slack), or active sponsorships.

Licensing & Compatibility

The project is released under the MIT License. This permissive license generally allows for broad adoption, including use within commercial applications and integration into closed-source software without significant restrictions.

Limitations & Caveats

The primary explicit limitation is the hardcoded safety mechanism that automatically terminates reasoning after 20 thought steps, potentially interrupting the analysis of highly complex or lengthy problems. The README does not provide further details on other potential limitations, known bugs, or the project's overall maturity beyond its fork status.
