Get differences between two texts in Unified diff format

Overview

What is mcp-server-diff-python?

mcp-server-diff-python is an MCP server that computes text differences between two strings using Python's standard library difflib. It returns differences in Unified diff format, making it useful for text comparison and version control tasks.

How to use mcp-server-diff-python?

Install and run via uvx mcp-server-diff-python or clone the repository and use uv run. Add the server configuration to Claude Desktop's claude_desktop_config.json. The server exposes a single tool, get-unified-diff, which takes two required string arguments (string_a and string_b) and returns the diff in Unified diff format.

Key features of mcp-server-diff-python

  • Single tool: get-unified-diff for computing text differences.
  • Returns differences in Unified diff format.
  • Leverages Python's built-in difflib library.
  • Lightweight—no external dependencies beyond Python standard library.
  • Runs via uvx or local uv installation.

Use cases of mcp-server-diff-python

  • Comparing two versions of a document or code snippet.
  • Generating patches or change summaries between text revisions.
  • Enabling AI assistants to show what changed between two text inputs.
  • Version control workflows requiring inline diff output.

Frequently asked questions

1

3

How do I install and configure the server with Claude Desktop?

Add the server configuration to your Claude Desktop config file using `uvx mcp-server-diff-python` as the command, or clone the repo and run via `uv run` with a local directory path.

4

What library does the server use to compute diffs?

It uses Python's standard library module `difflib`—no additional dependencies are needed.

5

Is there a way to test or debug the server?
