10 capabilities over ARD, MCP and WebMCP. First atlas observation.
10 capabilities, 9 of them tools. 4 only read. 5 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 9 tools, and 4 have AI readings.
4 tools are read as read-only, including get_service_info, list_errors and get_error.
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.

Exact states and meaning
- ARDobserved
Exact state: valid · Revision v0.91 · 1 retrieved artifact
A usable protocol document was retrieved and validated.
Directly observed
- A2Aabsent
Exact state: not found · 0 skills
The supported discovery location returned no matching document.
Not found does not prove the service exposes no such interface elsewhere.

A usable protocol document was retrieved and validated.
Directly observed
- 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
- WebMCPobserved
Exact state: observed · 1 declarative form tool · experimental
The origin root HTML, or a followed page, declared WebMCP form tools. InterfaceDelta ran no scripts and submitted no forms.
A declaration does not prove the tool works. WebMCP is an experimental browser capability.

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 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.
