Natal Compass in your assistant
Add the Natal Compass connector once and your assistant answers chart questions from real planetary positions, computed by precise astronomical calculations, instead of estimates. Nothing to install and nothing to pay.
The connector address is https://natalcompass.com/mcp. In Claude, add it under Customize, Connectors, Add custom connector. In ChatGPT, add it under Plugins, MCPs, Add, as a remote server with no authentication, then enable it in the chat. In Gemini CLI, add it to the mcpServers block of your settings file. In Antigravity, add it to the raw MCP config under Manage MCP servers.
Seven tools: a birth chart from a date, time and place; where the planets are on any date; how the sky on a date relates to a birth chart; the Moon phase; the retrograde periods of a year; the aspects between two charts; and a solar return chart. Positions and patterns, not predictions.
