Self-Hostable

The hosted version of MCP Factory is a convenience, not a lock-in. The entire factory is open source and ships as a single Docker container.

Stack

• FastAPI + SQLite (or Postgres for multi-instance)
• Single container, ~30MB
• One env var to boot: encryption key
• Reverse-proxy behind Caddy, Nginx, or Cloudflare Tunnel

Why self-host

• Compliance: regulated industries that can’t put OAuth refresh tokens in a third-party SaaS
• Cost: at scale, hosting it yourself is cheaper than the Pro/Team plans
• Control: choose your own encryption strategy, your own backup cadence, your own audit log retention

Migration path

Start on hosted, move to self-host later — or vice versa. The credential dump/load is documented and stable. Nothing in the API changes.
