Vibelens Mcp
This server bridges the gap between AI-generated code changes and human-readable review. It exposes a show_diff_explanation tool that lets Claude review its own diffs and write inline annotations explaining what changed and why. The companion VS Code extension watches a local file store and renders the annotated diff in a webview panel with side-by-side or unified views powered by diff2html. Action buttons let you fire prompts back to Cursor chat for refactors or test suggestions. Reach for this when you're tired of scrolling through chat transcripts trying to reconstruct what the AI actually modified across multiple files.

VibeLens
AI peer review for your code changes.
Just like humans review each other's PRs, your AI reviews its own changes with inline annotations that appear directly in a VS Code/Cursor panel.
Why AI Peer Review?
When humans write code, we do peer review. When AI writes code, we often scroll through chat hoping we understood what changed.
VibeLens gives AI the same workflow humans use: review the diff, annotate the changes, and explain the reasoning next to the code.
How It Works
AI makes changes -> AI reviews its own diff -> VibeLens opens an annotated panel
The AI calls the show_diff_explanation MCP tool after completing a task. The MCP server stores the review locally, and the VS Code/Cursor extension renders the diff with inline annotations.
Action buttons let you send improvement suggestions directly to Cursor chat.
