mcp-server-diff-python MCP Server: Seamless Text Comparison for AI Applications

Overview: What is mcp-server-diff-python MCP Server?

The mcp-server-diff-python is an advanced MCP server designed to provide text comparison capabilities through Python's standard library difflib. By generating Unified diff format outputs, this tool serves as a vital piece in the puzzle for AI applications that require context-rich data manipulation and version control functionalities. It enhances Claude Desktop, Continue, Cursor, and other clients by offering efficient text difference calculations, thus enabling developers to build more robust and user-friendly AI interfaces.

🔧 Core Features & MCP Capabilities

The mcp-server-diff-python server introduces key features that are integral to the Model Context Protocol (MCP). These include:

• Unified Diff Calculation: The primary function is generating Unified diff format, which highlights the differences between two strings. This feature aligns perfectly with AI applications needing granular context-aware modifications.
• CLI Interface: Offering a command-line interface (get-unified-diff) for quick and seamless integration into various workflows.

Detailed Description of Features

mcp-server-diff-python supports two primary methods:

1. Tool: get-unified-diff
   • Arguments:
     • string_a: Source text for comparison (required).
     • string_b: Target text to compare against (required).
   • Return Value: A string containing the differences in Unified diff format, enabling easy integration into version control systems or AI application interfaces.

MCP Protocol Implementation Details

MCP protocol ensures that all servers and clients communicate seamlessly. For mcp-server-diff-python, this involves:

• Sticking to a standardized API that allows for compatibility across various AI applications.
• Ensuring data integrity and consistency through structured JSON output formats used in the MCP ecosystem.

1. Clone the repository:

   git clone https://github.com/tatn/mcp-server-diff-python.git
   cd mcp-server-diff-python
   uv sync
   uv build
   

2. Add configuration to claude_desktop_config.json:

   "mcpServers": {
     "mcp-server-diff-python": {
       "command": "uv",
       "args": [
         "--directory",
         "path/to/mcp-server-diff-python",
         "run",
         "mcp-server-diff-python"
       ]
     }
   }
   

Windows

For a full setup on Windows:

1. Clone the repository:

   git clone https://github.com/tatn/mcp-server-diff-python.git
   cd mcp-server-diff-python
   uv sync
   uv build
   

2. Update claude_desktop_config.json with the following configuration:

   "mcpServers": {
     "mcp-server-diff-python": {
       "command": "uv",
       "args": [
         "--directory",
         "%APPDATA%/Claude/claude_desktop_config.json",
         "run",
