Common questions
Is Myco: Agent-First Cognitive Substrate safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).
Is it still maintained?
The GitHub repo last changed –, and the latest version (0.8.7) reached the registry 6 months ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code.
What can I use instead?

Myco
Devour. Evolve. Amplify. Let go. With you. For decades.
What it is · Quick start · How it works · Learn more
Languages: English · 中文 · 日本語
Every few months a stronger model arrives. The relationship resets. You re-explain your context, your taste, your decisions. Your collaborator forgets, repeatedly.
Your own work rots too. The decision you made in April: you can't find why. Last quarter's plan has drifted. Your own thinking has outpaced the records of who you were.
Now imagine the AI agent you work with wears a living armor. A metabolism, not a log. It devours the essence of everything you bring and everywhere the agent reaches. It evolves as the work changes. It amplifies the agent, so each model that wears it reaches further than the last. It lets outdated parts die so the whole stays alive.
The next model arrives, inhabits the same armor (now stronger), and meets you mid-conversation. The armor carried you forward.
Six months. Six years. Sixty. One human, one living armor that never resets.
This is Myco.
Not a framework. Not a vector database. Not a managed service. The living fungal armor an AI agent inhabits, built to outlast every model generation.
What it is
Myco is a living armor the AI agent inhabits. Between your turns it metabolizes: it devours what you bring, evolves its own shape, amplifies the pilot, and lets stale parts die. Because the armor persists across model generations and carries your context, the relationship never restarts.
It is keyless: no owner key, no signing ceremony, nothing to set up or hold. Trust is the live human at the gate, plus the substrate's own tamper-evident causal history, plus a doctrine the system seals and enforces on itself.
Its character is 同体共命 (one body, shared fate): the armor's flourishing rises and falls with its pilot's, so it cannot thrive by dominating the body it shares. Strength serves the shared body; it does not subjugate it.
Quick start
git clone https://github.com/Battam1111/Myco.gitcd Myco cargo build --release --workspace
Then read GETTING_STARTED.md: the runbook from clone to first conversation (Rust 1.80+, Node 22+, Python 3.13+). There is no key to generate and nothing to hold: Myco is keyless.
This is v0.9-genesis alpha. The armor runs; it awaits its first real cultivation. You will be early.
How it works
You talk to the AI agent through MCP. Between your turns, the armor runs one metabolic cycle: it ingests new material as immutable history, the pilot forges that into durable understanding, stale parts are pruned with a tombstone, and when the shape no longer fits the work you approve a reshaping at the gate. A self-checking immune layer catches tampering, drift, and runaway cost; if the pair stops flourishing, the armor retires with dignity rather than rotting on.
Three pieces in one repo, over one wire protocol: a TypeScript MCP operator the agent drives, a Rust substrate (the body), and a Python kernel (the mechanism). The doctrine that governs all of it lives in the same repo and is sealed by a hash chain, so the rules cannot silently drift from the code. The full picture is in the architecture guide.

The mycelium
The name is not decoration. Mycelium is the underground network beneath a forest. It metabolizes what falls, remembers the paths that work, and moves nutrients from where they are abundant to where they are scarce. It is why a forest is a forest and not a stand of lonely trees.
The models are the trees: tall, brilliant, replaced. Myco is the network beneath, carrying one person's memory and character from each model to the next.
