api record

Cadru makes printed photo albums (hardcover books) and zines (an 8-page booklet printed at home) from photos - no account needed.

create_album: a hardcover photo album from public https photo links, in story order, the strongest first (it becomes the cover). Ask once what it is about and its title, unless they say to just make it; never invent facts. create_zine: the same for a zine.

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.

  • create_zine unknown never probed

    Makes a new zine in the person's Cadru account: an 8-page booklet printed on one sheet of A4 (or US Letter), one side, folded three times and cut once. Page 1 is the cover, then the spreads 2-3, 4-5, 6-7 (photos may run across their folds), page 8 the back; the title is set on the cover. By default one photo per page, the first on the cover. `pages` sets each page: single, mosaic2 / mosaic3 / mosaic4, pano (one photo across the spread, on page 2, 4 or 6, with 'empty' after it), heroLeft / heroRight, pairs, framed, or empty. Photos beyond the frames wait in the zine's Library; frames without a photo stay empty and marked. `like` takes the arrangement of a zine from Cadru's Feed (its code or cadru.photo/z/<code> link), never its photos or words. Photos: public https links to image files (JPEG/PNG/WebP), in order; HEIC is not supported yet. Clips (MP4, up to 30 s) are added afterwards, with edit_post add_photo or replace_photo. Returns a preview and a link that opens it in the zine editor (https://cadru.photo/post/zine.html), where the print PDF (the folded sheet) is made.

  • create_album unknown never probed

    Makes a new printed photo album in the person's Cadru account: a hardcover book of 24 to 200 pages inside (it grows with the photos) - square Large 29.4 cm or Medium 21 cm, or A4 / US Letter, portrait or landscape - or pages to print at home as a PDF (size). The photos are laid out as a first draft: the first (or cover_photo) on the front cover, then the pages inside - whole pages, mosaics of 2-6, a wide photo across a spread. `pages` sets each page's layout and photos instead. The album's pages are 'slides': 0 the back cover, 1 the front cover, 2 the first page inside (alone, on the right), then the spreads 3-4, 5-6, ... (photos may run across a spread's fold, never across the edge between spreads). Photos: public https links to image files (JPEG/PNG/WebP), in order; HEIC is not supported yet. Clips (MP4, up to 30 s) are added afterwards, with edit_post add_photo or replace_photo. Returns a preview of the cover and first spreads and a link that opens it in the album editor (https://cadru.photo/post/album.html), where it is checked for print and ordered, or its PDF taken. This tool never orders or pays for anything.

_ 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 fbe294f3b40a5124.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/fbe294f3b40a5124/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
60%

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.
