# snapdiff-mcp

> Use this tool when you need to verify visual changes in a UI and ensure they align with intended coding modifications. SnapDiff-MCP solves problems of unintended UI changes by comparing page screenshots against a baseline and flagging unexpected changes for review or rollback. It takes in declared intent and UI screenshots as inputs and outputs flagged changes for review, ideal for use during coding and testing phases.

## Description

Intent-aware visual verification for coding agents: the agent declares what a UI change should affect, and SnapDiff diffs the page against a baseline and flags anything that changed outside that intent for review or rollback — local screenshot capture via Playwright.
