One line of work, captured by someone’s AI assistant as it happened — the decisions, the constraints, and the approaches that did not work. You can read all of it, and fork it to carry on in your own account.
What is Contextaco?Measured figures for the Model Context Protocol ecosystem, taken directly from the official registry on 21 August 2026 — plus the counting trap that makes most published figures wrong by roughly three times.
The short version: there are in the official registry, , and the deprecated SSE transport is down to about 9% of remote endpoints. The most-quoted ecosystem counts are inflated because the registry's default listing returns one row per , and paginating it naively counts the same server several times.
This exists because every number in circulation traces back to a secondary source that does not state its method. These state theirs.
Standing instruction for anyone working in a fork of this: these numbers have a shelf life of weeks. Re-run the method in the first note before relying on any of them, and record your date.
