QueueLess

Inspiration

Booking an appointment is easy. Waiting for one is not. We all know the loop: refresh, check again, still nothing. QueueLess exists so the agent does the waiting - and you only show up when there’s something worth deciding.

What it does

QueueLess is a simulated appointment marketplace where humans and agents share the same live page:

Search & compare available slots (time, price, category)
Recommend a pick the human can understand
Approve before reserve - nothing books without a human yes
Keep Watching - if nothing fits, the agent polls until a match appears, then asks again

Flow: search -> compare -> approve -> reserve
When inventory fails your constraints: keep_watching -> check_watch -> ask human

How we built it

Vite + TypeScript (no backend)
WebMCP via document.modelContext.registerTool() (fallback: navigator.modelContext)
Shared app store so UI clicks and agent tools hit the same inventory
On-page Run demo for judges who want the full loop in ~60 seconds

WebMCP tools

Tool	Role
`get_app_state`	Snapshot + suggested workflow
`search_slots`	Filter marketplace inventory
`compare_slots`	Rank + recommend
`reserve_slot`	Propose (`confirm: false`) then book (`confirm: true`)
`cancel_reservation`	Release a booking
`notify_user`	In-app toast
`keep_watching`	Arm a watch rule
`check_watch`	Poll for matches
`list_reservations` / `list_watches` / `stop_watching`	Helpers

Why WebMCP

Agents shouldn’t scrape buttons and hope. QueueLess exposes structured actions with JSON schemas on the page itself - same session, same state as the human UI. Write actions stay human-gated.
