A flock of AI users tests your deployed app and reports where real people get stuck, with fixes.
Connect Canaryusers to Claude, Cursor or any other MCP client and it stops being a tab you switch to. A flock of AI users tests your deployed app and reports where real people get stuck, with fixes. The canaryusers mcp server is what makes that connection.
You point it at a URL; a flock of AI personas actually renders and explores the page like real users, then hands back prioritized, fix‑ready findings — not a vague score. Two modes:
The toolset is worth reading before you wire it up, because it tells you what the integration is really for:
canary_scan — Run a UX scan on a deployed URL. depth: quick (free, default) or deep (visual + flow, uses a credit). Returns AI‑ready findingslist_recent_scans — List your recent scans (id, URL, score, grade, status, date)get_report_markdown — Fetch the full report for a scan id as MarkdownConfiguration is passed through the environment: YOUR_CANARYUSERS_TOKEN. Treat anything key-shaped as a real credential — scope it to the minimum the server needs, and rotate it if it ever lands in a shared config.
Because this one is hosted, setup is mostly authentication — you point your client at the endpoint and approve access. Nothing runs on your machine, so there is no runtime to keep patched.
Plenty of payments and commerce servers cover similar ground. The differences that matter in practice are scope of access and how much setup stands between you and a working tool call. Canaryusers's toolset — canary_scan, list_recent_scans, get_report_markdown — is a fair guide to whether it matches your workflow. It is maintained by ai.canaryusers; worth a glance at recent repository activity before you build anything load-bearing on it.
We check each listing at SyncDev against the project's documentation before it goes live — if something here drifts out of date, it is a bug worth reporting.
