About three.ws Notifications
Your three.ws notification inbox, delivery preferences, and Web Push devices — from any AI agent. A Model Context Protocol server that gives an AI assistant its own three.ws notification inbox + delivery control over stdio. Read inbound events (pump/market alerts, sales & earnings, purchase receipts, social mentions, IRL interactions, account/security notices), mark them read, tune the per-category → per-channel delivery matrix, and register Web Push devices — all live, all account-scoped.
