Diff Checker API
Line-by-line diff two text blobs inside your agent during reviews, doc edits, or config change checks.
Overview
Diff Checker is a MCP server for the Ship phase that compares two texts line-by-line and reports additions, deletions, and unchanged lines over SSE with x402.
What is this MCP server?
- Line-by-line text comparison with additions, deletions, and unchanged segments
- Diff Checker API as remote SSE MCP (no local diff binary required)
- x402 micropayment on diff-checker.api.klymax402.com/mcp
- Version 1.1.0 published server schema and GitHub repository
- Useful for PR summaries, policy text, prompts, and generated config deltas
- MCP server version 1.1.0
- Line-by-line comparison model (add / delete / unchanged)
- Single remote SSE endpoint with x402 micropayment
What problem does it solve?
Pasting two versions into chat makes it easy to miss small edits when you review docs, prompts, or configs before release.
Who is it for?
Indie devs who want fast textual diffs inside MCP agents during PR review, content updates, or spec iterations.
Skip if: Large-repo semantic diffs, binary files, or CI pipelines that need free unlimited git-native diff at megabyte scale.
