MCP Server Diff Python

🚀 mcp-server-diff-python

An MCP server for obtaining text differences between two strings. This server leverages Python's standard library difflib to efficiently generate and provide text comparison results in Unified diff format, making it ideal for text comparison and version control.

🚀 Quick Start

This MCP server is designed to obtain text differences between two strings. It uses Python's standard library difflib to generate and provide comparison results in Unified diff format, which is very useful for text comparison and version control.

✨ Features

Tools

The server offers one tool:

• get-unified-diff: Retrieve the differences between two texts and return a string in Unified diff format.
  • Parameters:
    • string_a: The source text for comparison (required).
    • string_b: The target text to compare against (required).
  • Return value: A string in Unified diff format containing difference information.
