9 capabilities over MCP. The inventory is incomplete. First atlas observation.
9 tools. 9 only read.◇
AI reading, beta. side-effects v1 on claude-haiku-5.5, calibrated on MCP (golden-3). Only readings above a measured precision count. Counts are tools, not calls: no tool was called.
AI summary · beta
9 capabilities are each read as read-only: search_book, search_works, list_chapters, get_chapter, get_work, list_collectors, get_collector_profile, get_registry_info, get_token.
The 9 capabilities are MCP tools that take no inputs.
Written by claude-haiku-5.5 from the tool names and the readings on this page, then checked against them. It can still be wrong; it never lowers or hides a fact.

The supported discovery location returned no matching document.
Not found does not prove the service exposes no such interface elsewhere.

Inventory incomplete. The displayed count is a lower bound; missing items do not prove removal.
None recorded in this Passport.
Not observed in this Passport: MCP resources, MCP prompts, OpenAPI operations.
The atlas shows each capability by its plain identifier, inputs and declared sign-in. Publisher descriptions, paths, links and source evidence are not published here.
The comparison with the previous observation is shown only to the account that recorded it.

Each class compares an observation with the previous atlas observation. Runs of unchanged observations are grouped. Struck values are what the previous observation recorded; inserted values are what this one recorded.
Declared and observed
9 tools declare hints; the AI readings agree with all 9 that have a reading.
A disagreement is not a finding about the service: either side can be wrong. How we compare declarations and readings.
