The ATF universe recasts the Seven as modern day ATF ("Alcohol, Tobacco, and Firearms," a U.S government agency) agents, known as "Team 7." It is notable for being as, or more, popular than the canon universe (referred to as Old West or OW). It has its own 'canon' and 'AU' interpretations, including such details as the cars each of the Seven drive.
From a fan in 2002: "Many thanks to Mog, for the creation of the ATF AU and for graciously allowing others to live in it." 
[With]... the tendency of fanfic authors to re-imagine characters in various settings, it should come as no surprise that one of the authors within the tv fandom, MOG, re-imagined the 7 in the present day, as ATF agents based in Denver. This is one of the most popular AUs I've ever seen, and it's easy to see why: we need heros today, and the Magnificent 7 are the sort of heros we need. One of the things about Magnificent 7 fandom is that AUs are often left 'open' to other authors, ie, although MOG came up with this idea, she has no qualms about other people writing in this universe, provided she's credited with the original idea. This is something of a brilliant idea - it is by no means original to Mag7 or MOG, but nonetheless, the creativity it invites is stunning.
The bible details the origins of the team, with Chris Larabee as the Group Supervisor of a multi-state team, "given the authority to pull from whatever law enforcement agencies he saw fit." Other team members were therefore drawn from the police, U.S. Marshals, and FBI.
The Guidelines and dossiers in the Bible include the location of the Seven's office, descriptions of their residences, cars and guns, brief in-universe character histories, and 'quirks' (e.g. Chris Larabee "is an excellent wood-worker. Owns every Johnny Cash album ever released (all in vinyl and has duplicated most of the collection in cd)."). It also includes resource links for writing about law enforcement & Denver.
However, stories are not required to (and many do not) hew to every detail in the Bible.
Other canon & fanon details
Vin Tanner, who is canonically illiterate in the show, is generally written as dyslexic in the ATF. The trope seems to have originated in Greenwoman's You'll Never Work In This Bidness Again and spread from there.
Heather F. created Team 8, headed by Ryan Kelly, in her story Second Guessing; the team has become a recurring presence in ATF stories.
ATF Vs. Old West
- Popular tropes - Case stories. POOR BEAT UP VIN.
- Poor Misunderstood Ezra: In Magnificent Seven fanfic, the character of Ezra Standish is frequently written as both mistrusted and mistrustful (with canon support, but fic plays it up hugely). The ATF universe ran with this, establishing that Ezra was both generally unpopular and wrongly suspected of corruption at his previous agency. Many, many ATF stories reference this backstory; depending on the story, Team 7 may either be initially suspicious of Ezra until they realize how wrong they are, or heartwarmingly demonstrate their reliability as the first people he can really trust.
- Same Actor Crossovers - Eric Close starred in Magnificent 7 as Vin Tanner and Without a Trace as Martin Fitzgerald. Since WaT was a law-enforcement show that could reasonably be concurrent with the ATF AU, this inspired a number of crossovers between the two. Sometimes Vin and Martin would turn out to be long-lost brothers, aided by the fact that Vin's background is very vague even in the canon universe.

- A Birthday in the Present by MOG (1999) was the first ATF story. She discusses its creation in this interview: "The ATF/AU came after Cassie Smith posed a birthday challenge for Chris. I was in the car, trying to work up some Old West plots and suddenly I had this mental picture of Vin being pushed out of an ER room while Chris was being worked on. I couldn't shake it. So I thought, okay, why are they there? A shooting. The OW guys are law enforcement, so that would work for modern times but I didn't want to use city police department (too overused) or FBI (that belongs to The X-Files) and my best friend's fiancee is following in the family footsteps and pursuing ATF so I thought, yeah, that agency would work."
