16 capabilities over MCP. The inventory is incomplete. First atlas observation.
16 tools. 4 only read. 6 only compute. 6 have no reading.◇
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 readings summary · beta
The service lists 16 tools, and 10 have AI readings.
4 tools are read as read-only, including search_cities, current_time_in_cities and get_dst_changes.
age_duration: Returns the elapsed time between two dates as years, months, days, and a signed total day count; end defaults to today.
search_cities: Returns matching cities for a name query, each with an ID, time zone identifier, and country.
Written by code from the AI readings on this page: it groups them and says nothing they do not.

Look first
AI reading, beta: AI adds items here; it never removes one.
No tool is read as one of the six effects. A zero is a count, not a clearance.

16 tools declare hints; the AI readings agree with all 10 that have a reading.
A disagreement is not a finding about the service: either side can be wrong. How we compare declarations and readings.
