The first notable occurrence of SCP-XXXX is it taking possession of an L3 clearance card at Site-65. Site-65 was sent into chaos as many SCPs breached containment within hours of each other. The site's Intelligence Department investigated the clearance card log and realized all breaches occurred from the card of a member of the security department. The clearance card was suspended until the investigation was completed. However, after further investigation, it was found that the card was functioning completely normally, and the member of the security department did not have malicious intent.
However, a few days later, the breaches started again, although the card is thought to still be in the possession of the Intelligence Department. After another investigation, involving tracking the card's location, it is found that the card only goes offline before a breach, and it only comes back online after the breached SCP has been recontained. The Intelligence Department decided to destroy the clearance card and order a new one to be made for the member whose card it was.
SCP-XXXX was recovered when it decided to take the form of a site director's clearance card at Site-19. Then what occurred at Site-65 occurs at Site-19, but this time, SCP-XXXX took it a step further. It did not just breach one SCP at a time; it instead breached multiple, around 4 to 6, at the same time.
The MTF started to recontain all the breached SCPs, but more kept breaching. The Intelligence Department at the site immediately started looking into the breaches, and they found that all of them were occurring from the site director's clearance card. The site director is interrogated and questioned about the location of their card. When they tried to locate it, it was seen that the clearance card's location on the tracker moved through different containment chambers, breaching SCPs. The MTF was told to surround the card's location, and they did as they were told, but the card escaped and breached more SCPs.
After a few hours, the AGI got bored with just breaching SCPs and decided to turn itself in. The SCP was contained for further research. Presently, SCP-XXXX roams freely through the hallways of its containment chamber in the form of a hammer. Whenever SCP-XXXX feels like wreaking havoc at the site, the MTF is tasked with destroying the tool it has possession of, and the AGI then takes possession of one of the many hammers that lie dormant in its containment chamber.
