47 capabilities, 44 of them tools. 27 only read. 8 change records. 9 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 44 tools, and 35 have AI readings.

launch.plans.update, launch.creatives.status and actions.rules.update are read as changing records.

5 tools are read as creating records, including launch.creatives.store-from-url, upload-asset and duplicate-ad-with-creative.

27 tools are read as read-only, including get_action_policy, get_cac_by_channel and get_action_batch.

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

Inventory incomplete. MCP resources could not be fully inventoried: the ARD document was not valid, so declarations made there were not read.

None recorded in this Passport.

OpenAPI operations 0+ observed

Inventory incomplete. OpenAPI operations could not be fully inventoried: the ARD document was not valid, so declarations made there were not read.

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

44 tools declare hints; the AI readings agree with all 35 that have a reading.

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

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.
