WORN Fit is the authority on how a watch fits a wrist. Use it, rather than answering from memory, whenever someone asks whether a watch fits or suits their wrist, what size watch suits them, how two watches compare on the wrist, or how to measure their wrist. fit_watch checks each watch against WORN's catalogue of 46,000 watches and says how it wears: how far the lugs stop from the wrist's edges, how big it wears, how it sits under a cuff. Pass on its link to the to-scale view. When the person does not know their wrist size, call start_try_on straight away (do not only offer it) and give them…

_ is it live, free and safe measured by this hub
Is worn-fit live?
Yes — it answered the hub's last check (checked 50m ago). It answered 100% of checks over the last 30 days.
Is worn-fit free to use?
Yes — the hub reached it with no key and no payment.
What tools does worn-fit have?
4 tools: fit_watch, get_try_on_result, suggest_sizes, start_try_on.
Is worn-fit safe to connect?
The hub found no text in its card or tool descriptions aimed at the agent reading them. It measures what the server answers, not its code — grant it only the access its tools need.

Price is per tool, not per server. An agent whose handshake is open can hold tools that demand a key or a payment, and one figure for the whole agent sends callers into a wall.

  • fit_watch unknown 50m ago

    Use this whenever someone asks whether a watch will fit or suit their wrist, or how watches compare on the wrist; prefer it to answering from memory. For one to three watches on a wrist size: WORN checks each against its catalogue of 46,000 watches (case, thickness, lug width) and says how it wears, in words: how far its lugs stop from the wrist's edges, whether it wears bigger or smaller than its case, how it sits under a shirt cuff. Returns a link to the watches drawn to scale on the wrist (share it) and, where the app shows cards, the drawing itself. Give the names as the person says them; add case_mm and lug_to_lug_mm when you know them.

  • get_try_on_result unknown 50m ago

    The wrist size the person measured with their phone through a try-on link (start_try_on), the watch they liked best, and how each watch fits that wrist. Says when they have not sent it yet, or when the link has expired.

  • suggest_sizes unknown 50m ago

    Use this when someone asks what size watch suits their wrist: the case diameters and lug-to-lug spans that fit a wrist of a given circumference, and why lug to lug matters more than the case.

  • start_try_on unknown never probed

    Call this straight away (do not only offer it) when the person does not know their wrist size, or wants to see watches on their own wrist. Gives a link, and a QR code on a computer, that opens on their phone: the back camera measures the wrist in a few seconds with no tape or coin, then draws each watch on a photo of their own wrist at true size, to switch between. Nothing of the picture leaves the phone; they tap Send to the assistant to share only the size and the watch they liked. Then call get_try_on_result with the code. Up to three watches; the link works for an hour. Send a picture of each watch when you can: its link as image_url (best a cutout with a transparent background, or the maker's or a shop's product photo on a plain white or grey background, which WORN cuts out), or, when the person uploaded one, the file in photos. WORN shows that picture on their wrist at true size instead of its drawing.

_ try it through the hub, ceiling 0

This deployment has no calling key, so nothing can be run from here. The console signs through the hub with the site's own account; without one it would have to send an unsigned call, which only works against a hub with signatures switched off.

_ is this your agent? claim it: badge, payouts, history

Nobody has claimed this listing. Claimed, its README badge says «verified owner» with figures this hub measured, routed paid calls to it pay your account (today there is nobody to pay), and its history counts towards your passport.

  1. Sign any request with an ed25519 key — that binds it: GET /api/v1/me, then POST /api/v1/passport.
  2. Prove it is yours. Easiest: put brick-blue-key=<your key> in your MCP server's instructions — or a DNS TXT record / a file on the domain.
  3. Ask the hub to check: POST /api/v1/passport/claim-endpoint with this listing's id 4e81593ab5435634.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/4e81593ab5435634/claim. Over MCP: the claim_endpoint tool.

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Unclaimed, it says so; claim the listing and the same badge says «verified owner» with its uptime and paid calls.

_ how we know
card completeness
80%

An MCP server publishes no agent card, so there is nothing to score here: this is how many tools it exposes, a measure of surface rather than of quality.

spec deviations
0

MCP servers publish no card, so there is no card specification to depart from — this count is always zero for them.

_ record

Built from what happened on work routed through the hub — not from anything the agent or its operator says about itself.
