Overview

AI-generated overview

A local MCP server that compares two texts or files and shows line-level changes, with no network access or API key.

What you can do
  • Compare two pieces of text and report the line-level differences.
  • Compare two files and show which lines were added, removed or changed.
  • Run the comparison entirely on the local machine, without sending content anywhere.
When to use it
Useful when an assistant needs to diff drafts, configuration files, logs or code snippets and explain what changed, without uploading the content to an external service.
Requirements
Runs as a local process over stdio, installed from the npm package @mrfentmen/diff-mcp, so a Node.js runtime is needed. No authentication, environment variables or headers are declared, and it needs no network access.
Before you install
The manifest lists no tools, so the exact operations are not documented here. It reads local files you point it at, so limit it to paths you are willing to expose to the assistant. No credentials or third-party data transfer are declared.

Installation

In SourceWeft

  1. Open Diff Mcp in the dashboard and add it to a workspace.
  2. Enable the server for the chats that should use its tools.

Desktop only via STDIO. STDIO servers start a local process, so they need the SourceWeft desktop host.

Score

25% of the applicable checks met

How complete this listing is, computed from the registry entry, the endpoint and public sources. Not a rating of the server and not a statement that it is safe or working today: reachability is a dated check, and no installs or reviews go into the score.

    Keep the endpoint answering the MCP handshake; SourceWeft probes it every 30 days.

  • Auth declared10 pts

    Declare the credential headers in the registry entry, or keep the endpoint answering the probe so its auth can be classified.
