git-conflict-mcp

A powerful Model Context Protocol (MCP) server designed to help AI agents and developers resolve Git merge conflicts efficiently. It includes a built-in visual WebUI for interactive conflict resolution.

Features

• MCP Tools: Full suite of tools for agents to detect, read, and resolve git conflicts.
• Visual WebUI: A dedicated web interface (default: http://localhost:3456) for human-in-the-loop resolution.
  • Syntax Highlighting: Read code clearly with automatic language detection.
  • Diff View: See changes clearly with intelligent diff display.
  • Editable Interface: Directly edit conflicting files in the browser.
  • IDE Integration: One-click opening of files in your preferred editor (VSCode, WebStorm, Cursor, etc.).
• Smart Port Management: Automatically detects if the WebUI is already running and reuses the instance to avoid conflicts.
• Conflict Tracking: Keeps track of resolution status and rejection reasons.

Usage

via npx

You can run the server directly using npx. This requires no manual installation if you have Node.js installed.

npx -y git-conflict-mcp

The WebUI will start automatically. You can access it at: http://localhost:3456
