# Postern

> Self-hosted personal context gateway: one MCP surface over the sectors
> of a person's life (finance, mail, calendar, contacts, health, home),
> with per-agent default-deny grants, an append-only audit ledger, and
> actions where the source allows. Runs on the owner's hardware; agents
> connect to the owner's gate, not to a Postern cloud. AGPL-3.0.
