post_astrology_solar_arc
ActiveTool of Western Astrology MCP Server by RoxyAPI
Calculate a solar arc directed chart for any birth moment and target date. The solar arc is the secondary-progressed Sun longitude minus the natal Sun longitude, about one degree for each year of life, and every natal point including the Ascendant and Midheaven is advanced forward by that same arc. Returns the solar arc, each directed point with its natal and directed longitude, zodiac sign, degree, and a plain language interpretation, for predictive astrology apps timing major life events. Built on accurate tropical chart positions, no astronomy expertise needed.

},
"time": {
"type": "string",
"format": "time",

"description": "Birth time in 24-hour HH:MM:SS format. Determines the Ascendant (rising sign) and house cusps. Use 12:00:00 if unknown."
},
"compact": {
"type": "boolean",
"default": false,
"description": "Set true to receive the exact same data in a token-optimized shape that is cheaper for you to read: whitespace is stripped and every array of same-shaped objects is encoded columnar as {\"__cols\":[field names],\"__rows\":[[values]]}, so each field name is sent once instead of once per row. Fully lossless (no field or value is dropped or changed) and typically 40 to 52 percent fewer tokens on large results. Prefer true whenever token or inference cost matters. Default false returns standard indented JSON."
