A Swiss Ephemeris backed astrology server that stores natal charts, transit lookups, and relationship charts in a local SQLite database. It exposes tools for creating multi-profile charts, querying historical planetary positions, generating composite and Davison relationship charts, and scanning date ranges for electional astrology. Every transit lookup gets auto-logged so you can query your astrological history by date, planet, or sign. Reach for this if you want programmatic access to precise ephemeris calculations with persistent storage, or if you're building conversational astrology workflows that need to remember past readings and manage charts for multiple people. Runs via uvx with no separate install.
