Public sample12 named servers · 34 joined between our copy of 22 Jul 2026 and our copy of 22 Aug 2026
The list we copy is the official Model Context Protocol register — the place a server puts itself so an AI agent can find it. It keeps its own history, and this page used to say it did not. Read on 25 Aug 2026, 600 entries came back: 447 of them were not the newest version of their server, 5 were marked taken down and served anyway, and every single one carried the date it was published. One name alone had 319 versions on it, the oldest published 10 Sep 2025. So a name taken down does leave a trace, and the register does show you more than what is on it right now. We still save the whole list every day, but we are not charging for it.

12 of the 34 are shown here, newest first. The full list, with both dates and the address on every row, is on servers that were newly listed.
Why every row carries two dates
The right-hand date is the register’s, and it is not a joining date. It moves forward every time the seller ships a new version, so a server that has been listed since June can print yesterday’s date. The only way to know when a name actually arrived is to have held the list on the day before.
The left-hand date is ours, and it is a fact about our copies, not about the seller. Where the two are more than a day apart we print the reason next to the row: either we hold no copy for those days, or our copy that day stopped at the first page. We would rather say that than let you assume we were watching on a day we were not.
The size of what we hold, and the honest count
We hold 29 dated copies of this register, one a day, from 22 Jul 2026 to 22 Aug 2026, and 3,036 dated rows inside them — one row per name per copy. Our first copy held 95 names and our copy of 22 Aug 2026 held 128. Across all 29 copies, 129 different names have been on the list at some point. 34 are in the newest copy and not in the first. One went the other way. We also caught 41 version changes on 19 servers, which is the only other thing the register will tell you about who has been shipping.
Every number in that paragraph was counted out of our own dated copies, and each one is shown again, broken down, on what is and is not in this feed. Ask us and we will show the working.
17 of our 29 copies stopped at the first 100 names. The register hands out 100 at a time and our reader did not ask for the second page until 14 Aug 2026. Every copy from that day on is the whole list, and both ends of the comparison above are whole copies — but on those 17 days a name could have been on the register and missing from our copy. 14 names disappear from a copy in the middle of their own run and come back later, and every one of those gaps falls on one of those days.
Three days inside our range have no copy at all: 8, 18 and 19 Aug 2026. A name that appeared and went away entirely inside one of those gaps was never in front of us.
One name has left the register while we were watching, and that means the register stopped listing it. It does not mean the company shut down or the server was switched off. We only know what the list said on the day.
We publish no score, no grade and no ranking of any named company, and we do not work one out. Three of the names in our copies sell exactly that, and they are kept off the tables on these pages for that reason. They are still inside every count above.
The register only tells us what a seller filed. We do not call the address to see whether anything answers. 49 of the 128 names on our newest copy give no address to call at all, and 36 of those 49 give no website either. 73 of the 128 do give a website. Every one of those is what the seller typed into the register, not something we checked.
Doing this yourself
You can read the register yourself in a second. What you cannot do is read yesterday’s. It is not versioned, not announced and not archived, and the date it shows against a server is the date of that server’s newest version, not the date it joined.
To answer “who shipped this month” you would have had to start saving the whole list a month ago, keep every copy, and then work out which differences are a real arrival and which are your own reader stopping short. That last part is most of the work, and it is the part we print rather than hide.
What you get
- Every name that joined or left the registerThe name, the first copy of ours it is in, the date the register itself gives, and the address it answers on.
- Every version change we caught between two copiesThe version before, the version after, and the two days it moved between.
- The days we hold no copy, namedYou get the gaps in writing, not a number that quietly assumes them away.
- The saved copy behind any row, on requestSo you can read the whole record for that name on that day.
- Nothing to payFree to ask for. No charge, no card, no subscription.
How it works
- You email us and say whether you want the whole list or only certain names. There is nothing to buy on this page and no checkout link to send you.
- We tell you what we already hold and since when — and we point you at the register’s own free version history, which reaches back further than our copies do.
- A person emails you the changes file at no charge, and names anything we could not collect.
What this page cannot tell you
The register tells us what a seller filed, and no more. We do not call the address to see whether anything answers. A name on this list is not proof of a working server, and a website in a row is what the seller typed, not something we checked.
A name leaving means the register stopped listing it. It does not mean the company shut down, the server was switched off, or anything went wrong. We only know what the list said on the day we read it.
We publish no score, grade or ranking of any named company. We do not work one out either. Several of the sources we read exist to sell exactly that, and the names whose product is a score are kept off these tables on purpose.
This is one search of the register, not the whole of it. Our copy is the servers that say they charge per call. A server in the register that does not say so was never in front of us and is counted nowhere on this page.
See the file
You do not have to take our word for what is in the file. Here are 25 rows of the real thing, carrying all 4 of its columns, cut out of the dated copies we sealed ourselves. Nothing in it is made up and nothing in it is tidied up.
- Open the 25 rows as a CSVA plain spreadsheet file. It saves to your machine rather than painting itself into a browser tab, and it opens in Excel, Numbers or Google Sheets.
- The same 25 rows as JSONThe same rows again, laid out for reading with code.
What arrives if you ask: a person emails you what you asked for as a CSV — the same plain spreadsheet as the sample above, not a login and not a web page — within one working day. There is no charge and no card.
These 25 rows are a slice of the file, not the whole of it. How far back our own copies go is the part this page cannot show you — ask and a person will tell you, at no charge.
Ask what we hold, at no charge
Not for sale. This page charged $99 for a dated archive copy of a register that publishes its own dated versions free. That was wrong, and it was taken off sale on 25 Aug 2026. There is no button on this page and no charge behind it.
If it is still useful to know what we sealed and when, email operations@ustechautomations.com. A person replies with which dated copies exist and names any day we did not seal. No card, no charge.
