What is the MCP MCP server?

Connect MCP to Claude, Cursor or any other MCP client and it stops being a tab you switch to. This is an MCP server that gets the difference between two texts. The mcp mcp server is what makes that connection.

What the server does

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

Available tools

The toolset is worth reading before you wire it up, because it tells you what the integration is really for:

  • get-unified-diff — Get differences between two texts in Unified diff format
  • Arguments — - string_a: Source text for comparison (required)
  • string_b — Target text to compare against (required)
  • Tools — The Tools tool exposed by this server
  • Debugging — You can start the MCP Inspector using npxwith the following commands:

Installation

Installation goes through your MCP client rather than a global install: point it at @modelcontextprotocol/inspector on npm and it is fetched when the client starts. The copy-paste blocks for Claude Desktop, Claude Code and Cursor are further down this page.

Where it fits

This sits in the developer tooling group, where several servers overlap in what they claim to do but differ sharply once you actually set them up. MCP's toolset — get-unified-diff, Arguments, string_b and 2 more — is a fair guide to whether it matches your workflow. It is maintained by tatn; worth a glance at recent repository activity before you build anything load-bearing on it.

This entry was verified against MCP's own documentation before publication; SyncDev keeps the directory reviewed rather than auto-generated.

Worth knowing first

  • It runs with your machine's permissions. That is convenient and also the reason to think about what you point it at before you approve a tool call.
  • Keep per-call confirmation enabled while you learn its behaviour; it is the cheapest safeguard you have.

How to install the MCP MCP server

}

Configuration as documented by the project. Restart the client after saving.

Example prompts to try

  • Use MCP to get-unified-diff.
  • Use MCP to Arguments.
  • Use MCP to string b.

Frequently asked questions

It connects MCP to MCP-compatible AI assistants such as Claude and Cursor, exposing 5 tools (get-unified-diff, Arguments, string_b, and more) that the assistant can call on your behalf. Instead of copying data back and forth by hand, the assistant works with MCP directly.
