The idea that there is no canon is a bit silly at times. It's not that we don't have any. It's that we have a multitude which touch, cross, and dip into each other. It's up to you, as the reader, to decide what you believe and what you embrace as the heart of the universe. That doesn't mean, though, that authors lack intent or design, and collaboration is the heart of innovation.
Collected below are links to the recognized, shared canons of the SCP Foundation Universe. To write in one, you should make sure that you read the other material from that canon and try to remember that these things are connected. If you're interested in forming your own canon, read the information at the bottom of the page.
We've always assumed the SCP Foundation was a necessary evil. But what if it wasn't?
When they've finished their brief conversation, Tang raises her forefinger to the anomaly, and right through the hole between worlds, the two scientists touch hands.

Six hundred years ago, the world ended. Today, only one group protects the secrets of the ancient world until a time when they can be understood again; the priests of the Holy Foundation.
"Saint Gears, please guide me in my time of need as you guided the Holy Foundation during the Great Breach.
Bequeath unto me the knowledge to discover that which is false.
Grant unto me the ability to separate logic from falsity.
Allow me to grasp but a portion of the knowledge you once had."
From "Quid Est Non Scitum" by Jekeled
The Antarctic Exchange is a canon which focuses on the lives and relationships of the researchers from the Third Antarctic Empire during their time at the Foundation.
It was enough that everyone looked and acted so different; still he stood out so much that sometimes the people here would turn away, would whisper to themselves about him, his companions, their tasks, their work. Antarctica. Empire. Emissaries. Secrets. Antarctica. He could both hear and understand them, but he wasn’t sure if he should let them know.
From "Impressions" by Zyn
At the edge of the mind lurks something that prays for the death of definition. It has been on the retreat for some time now, as the world has become a knowable, mapped place, no longer brimming with demons. Watch for it where knowledge lies, seeking to unmake everything known.
The word was carved into a rock. The man stood above it and, in the bottom of his mind, felt something stir. He did not know that he had just changed the course of all worlds, but he could feel something was different. The world had become a bit more orderly.
From "The Tale of the Library" by Rumetzen
The end of the world is here. But it's not just one end of the world. It's all of ends of the world happening at once, competing with each other, with the Foundation - and humanity - in the middle.
"What did you do? What is it? What did you unlock?" She could feel something vibrating in the back of her brain. Her eyes kept being drawn to the lock. It looked exactly the same, visually, but it was also incredibly different. "What's Apakht?"
"It's the End," the Harbinger said. The fabric of reality began to unfold before their eyes.

What was hidden now is seen. How will the Foundation survive in a world where secrecy is no longer an option?
"…day five of the rescue effort, and more bodies are being recovered from the ocean. Initial estimates put the death toll in the million range, with increases occurring constantly. The UN released a statement about the recent North Korean Incident, claiming that they believed it was 'an act of nature'. The recent leak of classified documents from the Japanese Diet pointing towards a theft from what is referred to as 'The Foundation' suggests a different story…"
From "Joseon" by Doc Burns
As the clash of communist and capitalist envelopes the world, the most covert organization on earth sinks deeper into hiding. What does it take to stay neutral in the face of governments who see the anomalous as just another means of escalation? How do agents react when loyalty to party clashes with duty to humanity? And just where should the Foundation go to escape a global war?
My beloved Dorothy,
There is a whole new war here, a new type of war, industrial and implacable. The American war machine has become unrecognizable.
Out in the jungle bear-clawed women hunt the Viet Cong through their own tunnels for hours before emerging. Airborne commandos on interdiction patrols carry weapons which calcify their targets in the blink of an eye. Villages suspected of sheltering the enemy are plastered in napalm that collects itself into a moving mass of fire and waits for survivors to emerge from cover before flaring back into life…
From "They Will Leave Us With a Shaken Earth" by Vezaz
The being known as Nobody is akin to a force of nature: his actions are unpredictable and his methods unclear. His purpose and true identity are a mystery to all, including himself. But when they are achieved, he will vanish. This has already happened at least once.
He paused and stared briefly at his own face in the mirror, trying to remember if anything about it looked familiar. Again, and as always, nothing was. He sighed. "Well, it doesn't pay to wonder. Off to work I go." He straightened his jacket one last time, solemnly tipped his hat to the empty room, and stepped through the doorway.
From "Prelude: A Terminus" by Drewbear
The Old Man in the Sea is a series of stories focusing on a race of space-faring biological arks, and the effects they have on the universe- such as those that one in particular, SCP-169, has on Earth.
Eventually, I will expire. That great impact shortens our lifespan, and the growth of a civilization within us does nothing to alleviate this. Eventually, those creatures within me will find an exit. Everything will change.
From "Eden" by Snowshoe
Rat's Nest is set in a universe where reality is falling apart due to the absence of LTE 0913, an energy being that had perpetuated our reality up until its destruction.
Friendship and spirit did nothing to prevent this. Their ideals, aspirations, and the hearts that birthed them could not produce the strength they needed. Respect and duty had long fell to the wayside, far from the binding contracts that they were thought to be. In the end, nothing they really believed in could’ve saved them…

Thousands of years after the end of the world, humanity has to deal with the remnants of the SCP Foundation's unfinished work.
If anyone could get you from one city to another, it was him (extra if he'd been outcast by the locals). If you wanted a relic from the old places, he knew where you could buy it, or, if the price was right, he'd fetch you one himself. The waterskin at his side was empty. Water was plentiful in the Waste, and it was one less thing to weigh him down. The real problem was food. Nothing grew in the waste. There were occasional birds and animals crossing the damp sands, but no trees or grasses of any sort.
The Beller knew the Waste well.

Josephine, a powerful reality bender, has been evading the Foundation using a combination of stealth and covert warfare, including memory manipulation on a wide scale. But deep within the Foundation, a small cadre works to capture her…if possible.
The next few moments were forever etched into Caleb’s memory. He heard the snap as the rope broke, and saw the little girl on her knees directly below it. He tried to call out to her, but even in that instant, he knew it wouldn’t do any good. He saw the crate falling, faster and faster, getting ever closer to the girl’s head…
…and then it wasn't.

Tales from the Horizon Initiative and other things of a theological nature.
The biggest problem, Salah thought, was how one went about killing a god. You could burn its scriptures, wipe out its worshipers, kill its avatars, but that would only ever delay it. Eventually it would come back, whispering, and the whole cycle would begin again. It could wait forever.

Life is like a hurricane here in Sloth's Pit. The people at Site 87 are just trying to make sense of it.
A reminder to all staff was issued that "All Halloween costumes based on Keter Class SCPs are forbidden. Most of them are classified, anyway. And yes, this does include -ahem- "sexy" costumes based off of SCP-682." West sighed at the fact that they had to be reminded of that. He remembered briefly considering taking a Class-Omega amnesiac after seeing one of those aforementioned costumes at a party three, four years ago. 682 with tits was just… wrong.

We all laughed, but it's not funny anymore.
Suddenly, King's mind was filled with images. He was riding an apple chariot into Site-19, and all the senior staff were apples. They bowed down to him, and readied the apple throne for him to sit in. Panning out, the site was apples. Slices made up every wall, and the head of every researcher was replaced with rotund, healthy apples. There was no danger, because skips were apple.

Protecting Humanity, Whether It Likes It Or Not.
Note that execution of Procedure Pizzicato will, by necessity, result in an irreversible Second Mission (Concealment) failure in order to allow for a First Mission (Survival) success. Third Mission (Protection) goals are secondary: normal avoidance of civilian casualties is to be second priority to maintaining Minimum Repopulation Margin among the survivors.
