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
- 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.

MCP tools 0+ observed
Inventory incomplete. The displayed count is a lower bound; missing items do not prove removal.
None recorded in this Passport.
Not observed in this Passport: A2A skills, 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.

No tools declare hints.
A disagreement is not a finding about the service: either side can be wrong. How we compare declarations and readings.
About this entry
com.buscalc/calculationsListedOfficial MCP Registry · first listed 12 Nov 2026 · last listed 12 Nov 2026

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.
