mcp-server-diff-typescript MCP Server

A Model Context Protocol server that provides unified diff generation capabilities.

This TypeScript-based MCP server implements a diff generation system. It provides a tool to generate unified diffs between two text strings, which is useful for comparing and analyzing text differences.

Features

Tools

  • get-unified-diff - Generate unified diff between two text strings

    • Takes oldString and newString as required parameters

    • Returns the difference in unified diff format

    • Uses the diff package for accurate difference detection

    • Includes 3 lines of context around changes

    Disambiguation5/5

    With only one tool, there is no possibility of ambiguity or overlap between tools. The tool's purpose is clearly defined as generating unified diffs between text articles, making it impossible to confuse with other tools.

    Naming Consistency5/5

    The single tool name 'get-unified-diff' follows a clear verb-noun pattern (get + unified_diff). With only one tool, consistency is inherently perfect as there are no other names to compare against.

    Tool Count2/5

    A single tool is generally too few for most server purposes, as it limits functionality and scope. While this server focuses narrowly on diff generation, having only one tool feels thin and may not cover related operations like diff analysis or formatting options.

    Completeness3/5

    The tool provides a core diff generation function, but the surface is notably incomplete. There are obvious gaps, such as no tools for comparing files, handling different diff formats, or managing diff history, which limits the server's utility for broader text comparison tasks.
