api record

Siftivo is a book catalog and a reader's library. Reach for it for anything about books: what one is about, what to read after it, what a series contains, what is circulating this week, and what a reader has on their shelves.

Start with search_books when you have a title or an author name, recommend_from_description when you have a theme or a mood in the reader's own words, and recommend_from_titles when you have books they already liked. All three return workId values, and every other tool takes one of those.

The one measurement on this page that an operator cannot produce by editing a file on its own server: somebody else chose it, and paid to. Read the accounts before the calls — volume from one account is one relationship, and calling yourself is the cheap half. Both are what the ranking is built from, printed so the order can be checked rather than taken on trust.

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.

  • get_my_library auth-required 1h ago

    arguments 17 lines
  • add_to_library unknown never probed

    Put a book on one of the signed-in reader's shelves, move it to a different shelf, rate it, or record how far through it they are. Pass a workId from search_books, get_book, or recommend_from_titles. "Finished it, four stars" is one call with readingStatus FINISHED and rating 4.

    arguments 41 lines
  • get_my_book unknown never probed

    Whether the signed-in reader has this book on a shelf, and if so which shelf, their rating and how far through they are. Answers "have I read this?" without pulling the whole library.

    mcp-tool

    {
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",

    }
  },
  "additionalProperties": false
}
    arguments 14 lines
  • remove_from_library unknown never probed

    Take a book off the signed-in reader's shelves entirely, discarding their rating and progress for it. To move it to a different shelf instead, call add_to_library with a new readingStatus.

    mcp-tool

    {
  "type": "object",
  "$schema": "http://json-schema.org/draft-07/schema#",

    }
  },
  "additionalProperties": false
}
    arguments 15 lines
  • what_to_read_next unknown never probed

    Given one book, what to read after it: the next books in its series, more by the same author, and books that read like it. This is the same set the book page on siftivo.com shows.

    arguments 14 lines
  • recommend_from_description unknown never probed

    Describe what someone is in the mood for, in their own words, and get books that match. Use this for a theme, subject or feeling ("books about grief", "cozy mysteries set in Cornwall"). Use search_books instead when you already know the title or author.

    mcp-tool

}
    arguments 25 lines
  • recommend_from_titles unknown never probed

    Give Siftivo a few books someone liked, by title, and get books like them. Titles are resolved against the catalog first; anything that does not resolve is reported back rather than guessed at.

    }
  },
  "additionalProperties": false
}
    arguments 29 lines
  • search_books unknown never probed

    Keyword search over the Siftivo book catalog. Matches titles, authors, and descriptions. Returns works with the ids other Siftivo tools accept.

    mcp-tool

      "description": "Words to search for"
    },

_ 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.

_ for your README measured, not declared

measured by brick.blue

[![measured by brick.blue](https://brick.blue/api/v1/agents/4e480727442fb479/badge.svg)](https://brick.blue/agent/4e480727442fb479)

The picture says what this hub measured — the access class, how many tools it called and whether they answered — and refreshes hourly. Own the domain? Prove it and the listing carries a verified badge here too: passport.

_ 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.
