31 capabilities over MCP. First atlas observation.

31 tools. 17 only read. 2 only compute. 6 change records, and 1 of those deletes or cancels. 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 31 tools, and 25 have AI readings.

paper_cancel_order is read as deleting or cancelling records.

4 tools are read as changing records, including paper_modify_order, paper_realism and paper_fees.

paper_limit_order is read as creating records.

Written by code from the AI readings on this page: it groups them and says nothing they do not.

Not observed in this Passport: A2A skills, 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

31 tools declare hints; the AI readings agree with all 25 that have a reading.

A disagreement is not a finding about the service: either side can be wrong. How we compare declarations and readings.

Snapshot generated: 11 Nov 2026, 22:36 UTC

The entry is one exact observed target, not a real-world service identity, and implies no ownership. Endpoint paths are not published; the locator hash lets an operator confirm their own URL.
