MCP Verify

A longitudinal record of what we observed when we looked at an MCP endpoint, and when we last looked. Every observation is dated and anchored.

This build

Last observed:2026-08-20T08:17:07.963Z— snapshot REL-SNAP-016.

12089 endpoints archived across 9026 distinct hosts. Endpoints and operators are not the same count — one operator can hold many endpoints, so an endpoint total on its own overstates diversity.

How that resolves: 13203 endpoints held · 12090 published (1113 below the observation threshold) · 1 affiliated and excluded from independent figures · 12089 counted as independent, across 9026 distinct hosts.

Published snapshots: 16, as of 2026-08-20.
A server is published once we hold at least 3 observations of it.

How REL-SNAP-016 was recorded

Every class the record declares, including those with no rows. A class shown only when it is non-empty would make "none observed" indistinguishable from "not measured".
