_ is it live, free and safe measured by this hub
Is shelfclub live?
Yes — it answered the hub's last check (checked 36m ago). It answered 100% of checks over the last 30 days.

What tools does shelfclub have?
6 tools: find_books_by_mood, search_books, get_book, get_similar_books, get_trending_books, get_author.
Is shelfclub 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.

what callers paid

inferred, not observed

Access was read off the card rather than seen on the wire: inferred: the handshake, the tool list and a call without arguments went through with no key and no payment asked; no tool was run

_ what it can do 6 tools
6 never probed 0 of 6 classified

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.

  • find_books_by_mood unknown never probed

    Find books in the Shelfclub catalog by mood, vibe, pace and genre tags. At least one tag is needed. Books that carry every requested tag are listed first, most read first; when there are fewer of those than asked for, books that carry some of the tags follow, and `matchAll` says how many of the books returned carry every tag. Each book is returned with its own tags. Returns up to 10 books, each with its Shelfclub id, authors, description, reader rating, series and shelfclub.app link. The tags are machine-generated.

  • get_book unknown never probed

    Look up one book in the Shelfclub catalog, by its Shelfclub id or by ISBN. Returns its description, authors, reader rating, series, an edition (ISBN, page count, publisher, publication date, language), its shelfclub.app link, and machine-generated mood, vibe, pace and genre tags. A lookup by id also returns the Shelfclub author id of each author that has an author record.

    List the books in the Shelfclub catalog whose mood, vibe, pace and genre tags overlap most with those of a given book.

  • get_author unknown 36m ago

    Look up an author in the Shelfclub catalog by Shelfclub author id, which get_book returns for the authors of a book. Returns the author's name, biography, birth and death dates and shelfclub.app link.

_ 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 b45ddef0ec551d5e.

Every step, filled in for this listing: https://brick.blue/api/v1/agents/b45ddef0ec551d5e/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
100%

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.
