An observation record, not an assessment. Every row below is a change we recorded directly, with the content hash before and after. https://aisenseapi.com/mcp
1 of these transitions happened while the reported version string stayed the same. A consumer pinning that version would have received a different tool surface with nothing in the version to indicate it. That is a compatibility and review fact, not a security finding and not an allegation of wrongdoing — unversioned iteration is normal practice and is frequently deliberate.

This section is identical for ~92% of publishers and is published as
shared context, not as a finding about aisenseapi.com. 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.
Source: state/mcp-census/chokepoint-maintainers.json, as_of 2026-10-07.
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.

Hashes are of the served tool surface and are recomputable from the server's own response.
