Right of reply. If any row is wrong — a change we attributed to you that isn't yours, a hash that doesn't match, a host that was reassigned — say so and we will correct or withdraw the record and publish the correction alongside it. Dispute or correct this record. We will also remove this page on request from the operator of mcp.revenuescope.jp.

Ecosystem context — not specific to this server

This section is identical for ~92% of publishers and is published as shared context, not as a finding about mcp.revenuescope.jp. 90 dependency packages sit beneath the measured MCP population; 41 have a single maintainer and 31 have not published in over two years. The widest is zod at 80.46% of npm-backed servers (8529 servers, 1 maintainer, last publish 2026-09-13). These are properties of the shared SDK dependency closure. Any page claiming this set as one operator's personal exposure is misreading a universal fact as a private one.

Coverage and limits

Observation window 2026-09-21 → 2026-10-10. 22,294 servers were observed; 2,214 were seen to change and 20,080 were observed and recorded no change — that negative control is why a non-zero count here means something. Across the corpus, 4,781 of 6,334 changes carried no version signal, and 1,690 of those added or removed tools.

What this does NOT cover: servers outside the observed set; changes that occurred before 2026-09-21; changes that began and reverted between two observations; and any server reachable only with credentials we do not hold. A server's absence from this record is not evidence it did not change — only that we did not observe it.
