MCP Servers

mcp-vsdiff

An MCP server that exposes VS Code's advanced diff algorithm as a tool, providing accurate unified diffs with move detection and annotations.

README

mcp-vsdiff

An MCP server that exposes VS Code's advanced diff algorithm as a tool.

What it does

Provides a single MCP tool, compute_diff, that computes a highly accurate unified diff between two strings using the same algorithm VS Code uses internally. Features include:

Move detection — identifies blocks of code that were moved, not just deleted/inserted
Unified diff output — standard @@-style hunks with 3 lines of context
Move annotations — deleted lines show {moved to block #N} and inserted lines show {moved from block #N}
Summary footer — total insertions, deletions, and moved blocks at the end

Usage

Install

npm install

Run

npm start

The server communicates over stdio and is compatible with any MCP client.

Tool: `compute_diff`

Parameter	Type	Required	Description
`originalText`	string	✅	The original text
`modifiedText`	string	✅	The modified text
`ignoreTrimWhitespace`	boolean		Ignore leading/trailing whitespace differences per line (default: `true`)
`includeMetrics`	boolean		Append a JSON metrics block to the response (default: `true`)
`verboseMetrics`	boolean		Add per-hunk breakdown to the metrics block (default: `false`)
`metricsOnly`	boolean		Return only the metrics block, no diff text — useful for large files (default: `false`)
`maxDiffLines`	number		Truncate the diff text if it exceeds this number of lines (default: `500`). Set to `0` to disable.
`skipDiffLines`	number		Number of diff text lines to skip from the beginning. Combine with `maxDiffLines` to paginate through very large diffs (default: `0`).

Metrics fields

Field	Description
`hunkCount`	Number of separate change regions (lower = easier to review)
`changedLines`	Real insertions + real deletions, excluding moved lines
`realInsertions`	Lines added, excluding moved lines
`realDeletions`	Lines removed, excluding moved lines
`movedBlocks`	Number of detected move operations
`movedLines`	Total lines involved in moves
`hitTimeout`	Whether the diff computation hit the 5 s time limit

ignoreTrimWhitespace gotcha: with the default true, a line whose only change is indentation (e.g. code moved into a deeper if block) will appear as unchanged context, making the diff look cleaner than a plain git diff would. Set to false if indentation changes need to be visible.

      "command": "node",
      "args": ["/path/to/mcp-diff/index.js"]
    }
  }
}
