Description, as the server wrote it
PRIMARY single-date tool. USE for any one Gregorian date when the ask needs moon phase (incl. blue/blood/supermoon/micromoon flags, Earth-Moon distance, phase_gmt, prev/next blue or blood dates), season/equinox anchors, classical retrogrades (retrogrades_active phase=retrograde), calendars, lunar year, Cosmic card (same card as life/sun — cosmic.also_called + planetary_spread.sun), karmic source/spirit, 14 planetary Life-spread cards, weekday or leap year (calendar_meta.weekday / is_leap_year), day_ruler (weekday planetary ruler Roman/Greek/Norse), or full date identity. NOT for two-person scoring → get_compatibility; name text → get_name. RETURNS cosmic block (incl. karma + planetary_spread) + tarot_majors (greer + tarot_school) + day_ruler (full+extended) + temporal blocks (moon_phase, season, retrogrades_active, calendar_meta, …). planetary_spread and retrogrades_active planets include planet_type/symbol/emoji + names{} (greek,norse,celtic,egyptian,sumerian,babylonian,mesopotamian,arabic,sanskrit,chinese). Each planetary_spread slot carries spread_pos (1-14 canonical Life-spread order; midheaven=13, phoenix=14 — sort by spread_pos; jsonb object keys are unordered). temporal_context={band, payload_scope} (band full|extended|out_of_range; payload_scope full|cosmic_card_only). Out-of-range responses set cosmic_card_available.

Run the operations that matter as governed actions.

Declare what an action changes, and Anlyon puts it under a shared limit, binds every approval to the exact request, and grades the outcome. It works on any HTTPS API you can describe as an action.

Anlyon does not run, proxy or govern this MCP server. A tool your own code calls directly is not routed through Anlyon and is not governed by it.
