x402 MCP Registry observed changes
Across the seven newest captured dates, 2026-09-01 through 2026-09-07, the sealed series supports 33 registry-publication or version-change events. A name crossing a historical capture's 100-result boundary is never called new; a missing name is never called removed.
Coverage limit. This is not a complete registry census. The Official Registry API returns 100 records per page. Newest collections can seal a cursor walk only after reaching a terminal page; historical captures predate that terminal-pagination proof. Absence is therefore not evidence that a server is unregistered. Names, versions, statuses, and dates reproduce Registry Data; they are not security reviews or endorsements.

Why absence is not a change event
The source API returns 100 latest-version matches per page. Newer receipts can prove a terminal cursor walk, but historical receipts cannot. We therefore publish only a registry-authored publication date inside the window or a version transition seen for the same exact registry name on two captured dates.
What these observed changes can support
The observed changes ledger answers a narrow procurement question: did the Official MCP Registry metadata for an exact named x402 server show a different version during our captured window? It does not test the server, inspect its tools, verify a payment, or infer that an update improved security. Reviewers can cite the dated source receipt and compare a version transition without turning registry presence into a trust judgment.
A continuity report retains the same evidence discipline over a longer customer-specified window. Each observed change travels with the two capture dates, the exact registry identity, and the collection seal. If a name appears on only one side of a capture, the report labels the comparison unavailable instead of manufacturing a publication or removal event.
