Yeah, this isn't all that great.
My main problem with this is that it just name-checks a bunch of famous Series I SCPs (namely 106, 173 and 999) and drops in an author self-insert for good measure, without bothering to provide any semblance of plot or character.
The characters also seem oddly juvenile for professional researchers, what with Mark laughing at a guy because he possesses a… mustache? and is short? ("He looked around the room and saw a small man with a big thick handlebar mustache that made him laugh aloud a little.").
What flimsy plot there is also doesn't make sense: 173 is not all that dangerous provided you get a lot of people to look at it, and in a cafeteria filled with researchers? It would be ridiculously easy to contain it with more people, not less, so why did they evacuate all personnel?
This concept has been done before, in the form of TroyL's In His Own Image (part 1 to be specific), but that worked because it built up the start of a decent character and made us want to see more. This tale, on the other hand, fails to captivate because it seems too focussed on name-dropping skips and leaving the characters and plot as flimsy sketches.
tl;dr: Work on making the plot and the characters stronger, because this story desperately needs them.
