5 capabilities over MCP. The inventory is incomplete. First atlas observation.
5 tools. 4 only read. 1 has 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 5 tools, and 4 have AI readings.
4 tools are read as read-only, including search_guides, get_guide and get_country.
search_guides: Lists guides and provider comparisons matching a text query, country, or topic such as eSIM, VPN, or maps.
get_guide: Fetches a compatibility guide for a given path, covering claims versus verified behavior, setup steps, failure modes and providers.
Written by code from the AI readings on this page: it groups them and says nothing they do not.

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.

Exact states and meaning
- ARDfailed
Exact state: unreachable · No document retrieved
The supported discovery location did not provide a usable response within the observation boundary.
An unreachable result does not prove the service is unavailable to every client or that it advertises no capabilities.

- OpenAPIabsent
Exact state: not detected · 0 operations
No endpoint was established from the evidence and scope that InterfaceDelta inspected.
Not detected does not prove that no endpoint exists.
Not observed / not fetched
- WebMCPabsent
Exact state: not detected · 0 declarative form tools · experimental
No named declarative WebMCP form tools were observed in the origin root HTML.
Script-registered tools and other pages are not observed, so this does not mean the site has no WebMCP tools.

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
5 tools declare hints; the AI readings agree with all 4 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.
