gmail-fan

Ein Local-first-Gateway für Gmail auf macOS: synchronisiert mehrere Gmail- oder Google-Workspace-Konten in SQLite, durchsucht sie schnell und stellt dieselben Operationen über eine JSON-CLI und einen lokalen stdio-MCP-Server bereit.

Gmail ist die maßgebliche Quelle. OAuth-Tokens liegen in der macOS-Keychain. Es gibt kein mitgeliefertes Modell, keinen Embeddings-Index und kein Model-Provider-SDK.

Voraussetzungen

  • macOS (Keychain + LaunchAgent)

  • Bun 1.4 oder neuer

  • Ein Google-Cloud-Projekt mit aktivierter Gmail-API und einer OAuth Desktop-Client-JSON
