Code Reasoning

mettamatt/code-reasoning

The Code Reasoning MCP server enhances Claude's ability to solve complex programming tasks by providing structured, step-by-step thinking capabilities through sequential reasoning and thought branching. It offers tools for exploring multiple solution paths in parallel, revising reasoning as understanding improves, and includes safety limits to prevent infinite loops, along with pre-defined prompt templates for common development tasks. This server solves the problem of enabling more deliberate, organized problem-solving approaches for coding challenges that benefit from breaking down complexity into manageable steps.

      }
    }
  }
}

Usage

  1. To trigger this MCP, append this to your chat messages:

    Use sequential thinking to reason about this.
    
  2. Use ready-to-go prompts that trigger Code-Reasoning:

Code Reasoning Prompts

  • Click the "+" icon in the Claude Desktop chat window, or in Claude Code type /help to see the specific commands.
  • Select "Add from Code Reasoning" from the available tools
  • Choose a prompt template and fill in the required information
  • Submit the form to add the prompt to your chat message and hit return

See the Prompts Guide for details on using the prompt templates.

Command Line Options

  • --debug: Enable detailed logging
  • --help or -h: Show help information

Key Features

  • Programming Focus: Optimized for coding tasks and problem-solving
  • Structured Thinking: Break down complex problems into manageable steps
  • Thought Branching: Explore multiple solution paths in parallel
  • Thought Revision: Refine earlier reasoning as understanding improves
  • Safety Limits: Automatically stops after 20 thought steps to prevent loops
  • Ready-to-Use Prompts: Pre-defined templates for common development tasks
