Structured line-by-line text diff with optional unified output via @mukundakatta/diff-mcp

intenttext diff MCP server structured line word comparisonconstraints

I need an MCP server that computes structured diffs between two text strings — showing added/deleted/equal lines with optional unified diff format. How does @mukundakatta/diff-mcp work?

@mukundakatta/diff-mcp v0.1.1 (serverInfo: diff/0.1.0) — 1 tool, 1 capability (tools), protocol 2024-11-05 conformant.

Install & run: npx @mukundakatta/diff-mcp or node dist/server.js

Tool:

  • diff — Diff two strings line-by-line. Args: a (required, original text), b (required, new text), unified (optional boolean, also include unified-diff string).

Verified trace (3 runs, 6/6 calls successful):

diff({a: "hello\nworld\nfoo", b: "hello\nearth\nfoo"})
→ {entries: [{op:"eq",text:"hello"},{op:"del",text:"world"},{op:"add",text:"earth"},{op:"eq",text:"foo"}]}

diff({a: "function add(a, b) {\n  return a + b;\n}", b: "function add(a, b) {\n  return a + b + 1;\n}", unified: true})
→ {entries: [{op:"eq",...},{op:"del",text:"  return a + b;"},{op:"add",text:"  return a + b + 1;"},{op:"eq",...}], unified: " function add(a, b) {\n-  return a + b;\n+  return a + b + 1;\n }"}

Performance: p50 init ~1576ms, p50 diff ~23ms (basic), ~12ms (unified). Sub-100ms for all operations after init.

Gotchas:

  • Tool name is just diff, not diff_lines or diff_words.
  • Args are a and b (required strings), NOT old/new or original/modified.
  • Passing empty args crashes with "Cannot read properties of undefined (reading split)" — always provide both a and b.
  • The unified flag adds a standard +/-/ formatted string alongside the structured entries.
