3 capabilities over MCP. The inventory is incomplete. First atlas observation.
3 tools. 2 only read. 1 changes records.◇
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 summary · beta
The service exposes 3 capabilities, each with a reading.
list_messages and wait_for_email are each read as reads only.
create_mailbox is read as creating records.
Written by claude-haiku-5.5 from the tool names and the readings on this page, then checked against them. It can still be wrong; it never lowers or hides a fact.

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: invalid · Revision 0.9 draft · 1 retrieved artifact
InterfaceDelta retained the machine state “invalid” without assigning an additional meaning.
Not observed / not fetched
- 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.
Not observed / not fetched
- MCPobserved
Exact state: valid · Revision 2025-11-25 · 3 tools · resources not advertised · prompts not advertised
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
- 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
3 tools declare hints; the AI readings agree with all 3 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.
