Find, reproduce and prove fixes for web-app bugs that depend on timing or layout with the GenClass MCP tools. Use when the user says something happens "sometimes", "randomly", "only in production" or "on slow connections", when a value "flips back", and for stale or old results, lost edits, double submits or a page that scrolls sideways on a phone; also after you change code that fetches, submits, autosaves, polls, debounces, paginates or listens to a socket, and before you call a page or UI…
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# GenClass: see the race, replay it, prove the fix GenClass records what happens inside the app's pages on this machine (each click, request, the order responses were delivered, what each response wrote into the state, uncaught errors with the click and request behind them), can run the page again with responses delivered in different orders, and can replay one exact order. It needs Claude Code (or another MCP client) on the developer's machine, next to the app's dev server; the chat app cannot run it. The server's instructions say when to reach for it; this file is the procedure. ## 0. Check the connection Call `genclass_status`. If no page is listed, call `genclass_setup`. It changes nothing: it prints an install line and the lines for the app's browser entry, behind a development check. Show the user those lines and wait for a yes before you run or add any of them. Then load a page of the dev server. ## 1. From a finding to a proven fix 1. `genclass_findings`, then `genclass_explain` on the most relevant finding. Read the causal chain (which click started which request, which response wrote over what). …

How to install
mdr add genclass-dev/genclass/genclass@sha256:caac78bed2bcde0aThe line at the top of this page pins the label git:20261105.5925bad, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
