Deep Code Reasoning MCP

haasonsaas/deep-code-reasoning-mcp

An MCP server combining Claude Code and Google Gemini AI that achieves deep code analysis through multi-model collaboration: Claude excels at local context operations and CLI workflows, while Gemini leverages its extremely large context window for distributed system debugging and long-trajectory analysis.

About Deep Code Reasoning MCP

An MCP server that pairs Claude Code with Google's Gemini AI for complementary code analysis. This server enables a multi-model workflow where Claude Code handles tight terminal integration and multi-file refactoring, while Gemini leverages its massive context window (1M tokens) and code execution capabilities for distributed system debugging and long-trace analysis.

Features

  • Gemini 2.5 Pro Preview: Uses Google's latest Gemini 2.5 Pro Preview (05-06) model with 1M token context window

  • Conversational Analysis: NEW! AI-to-AI dialogues between Claude and Gemini for iterative problem-solving

  • Execution Flow Tracing: Understands data flow and state transformations, not just function calls

  • Cross-System Impact Analysis: Models how changes propagate across service boundaries

  • Performance Modeling: Identifies N+1 patterns, memory leaks, and algorithmic bottlenecks

  • Hypothesis Testing: Tests theories about code behavior with evidence-based validation

  • Long Context Support: Leverages Gemini 2.5 Pro Preview's 1M token context for analyzing large codebases
