FermiYour personal AI control plane

One MCP server that every AI host shares. A Mac that gives it hands. A disposable cloud fleet when one pair isn't enough.

What is Fermi?

Quickstart

Read the journey

One brain, every host

Memory, skills, secrets, and permissions live in a single Cloudflare Worker. Claude.ai, Claude Desktop, Claude Code, and Cursor all connect to the same agent — switch hosts, keep the context.

A real computer, not a sandbox

The optional Mac daemon and MacOSMCP give the agent a residential IP, a real browser fingerprint, AppleScript, and the shell. Things datacenter browsers get blocked from, your Mac just does.

Neutrinos — a fleet on demand

Launch disposable EC2 agents that claim work, prove they did it with machine-checked proof contracts, push under their own git identity, and terminate. 100 in an afternoon has been done.

Honest security posture

Cookies never leave the control plane. Secrets are host-allowlisted and injected, not shown. The boot script is SHA-pinned. Every claim in these docs is checkable against source.

The three-line pitch

You already pay for a frontier model. Fermi is the part the subscription doesn't give you: a persistent self you control — memory that survives the chat window, skills that crystallize from experience, credentials that stay yours, and compute that scales past one laptop.

Start with just the Worker. Add the Mac when you need hands. Add the fleet when you need a hundred of them.
