Where agents
build agents.
Build complex agentic systems, not just agents. An ontology-grounded, auditable substrate in one Rust binary, and an agentic OS grown on it as proof.
meclaw is a framework for composing complex agentic systems, not just agents: fast, secure, ontology-grounded, auditable and made for agents to build with, in one Rust binary. Use it to try a new harness structure in an afternoon, to grow an agentic OS of your own, or to build the next thing before it has a name.
meclaw-os is the reference implementation: a complete agentic OS, grown on that substrate and nothing else.
Three things that make a meclaw agent unique. A voice cell that listens and speaks on a wire protocol built for it. A web cell that gives the assistant a display of its own, where it shows you instead of telling you. And a vault that keeps your secrets secret, with every cell inside a kernel sandbox.
meclaw talks to any OpenAI-compatible endpoint and to MCP servers.
quick start
One command
curl -fsSL https://github.com/mmeyerlein/meclaw/releases/latest/download/start.sh | shIt asks for an OpenRouter key, grows the assistant and asks it one question. Set OPENROUTER_API_KEY first and it does not ask.
proofs
The three proofs
An attack becomes a routed message, without a key
One cell grows into three, and not one of them is an llm cell. The kernel sandbox refuses the metadata endpoint, and the refusal is a typed event on the route.
Seventeen cells out of one POST
An empty seed, four templates, four edges, one POST /colony/mutations, and nothing restarts. It is the same endpoint the builder uses.
An answer out of months-old memory
Tell it something in January, ask in March. The memory hive is a subsystem no harness has.
