VerifiedAI canary users test your app and report real-user friction with fixes.
What is the canaryusers MCP server?
The server launches simulated AI users against any public or authenticated web app. Each session records navigation paths, errors, and confusion points, then generates concise reports with suggested improvements.
Results are delivered through the MCP interface so your AI client can review findings, prioritize issues, and track fixes over time without manual QA cycles.
