A remote astrology and Human Design engine that computes sky positions, bodygraph charts, natal sky SVGs, numerology and relationship charts.
What you can do
MysticAPI exposes seven tools over a remote HTTP endpoint. sky_today reports retrogrades, moon phase, geocentric positions for 13 bodies and a 30-day scan of stations and new/full moons; ephemeris returns raw ecliptic longitudes and retrograde flags for any UTC instant. bodygraph computes a Human Design (Energy Blueprint) chart with type, authority, profile, channels and gate maps plus an SVG, sky_personal renders a natal sky SVG, numerology derives life path and cycle numbers, relationship analyzes two charts together, and signature_lookup returns figure-signature canon entries.
When to use it
Useful when an assistant needs deterministic astronomy or Human Design calculations rather than free-form interpretation: current sky summaries, natal charts from a birth instant, numerology profiles, or compatibility analysis between two people.
Requirements
A remote MCP endpoint at the provider's site; no package, environment variables or headers are declared. Birth instants must be supplied in UTC, so local birth times need converting first. Several tools are metered per call.
Before you install
Several tools consume calls, so usage may be limited or billed depending on the provider's terms. Birth date and time data is sent to a third-party service, which is personal information. Outputs are presented as deterministic calculations, not advice.
Enable the server for the chats that should use its tools.
Web executable via Streamable HTTP. Remote servers run from the web runtime once configured in a workspace.
Use with an agent
Paste this prompt into Claude Code, Codex, Cursor or another agent — or into SourceWeft chat. The agent reads this server's install guide, shows you its publisher, endpoint and sign-in, and adds it to your client once you agree. Keys never go into a command.
Read https://sourceweft.com/mcp/io.github.Latimer-Woods-Tech%2Fmysticapi/install.md and connect the MCP server it describes to my client. Before changing any config, show me its publisher, endpoint and sign-in method and wait for my OK. Never put an API key in a command or in a file I would commit; ask me where it should come from.
Today's universal sky: which planets are retrograde right now, the current moon phase and illumination, geocentric positions for 13 bodies (zodiac sign + Energy Blueprint gate/line), and a 30-day forward scan of retrograde stations and new/full moons. No input. Deterministic astronomy (JPL-validated ephemeris). Costs 1 call.
Takes no parameters.
bodygraph
Compute an Energy Blueprint (Human Design) chart from a UTC birth instant. Returns type, authority, strategy, profile, definition, incarnation cross, channels, defined centers, and conscious/unconscious gate maps, plus a body-graph SVG. Location is NOT needed. Convert local birth time to UTC before calling. Costs 1 call.
Render a personal natal sky as an SVG from a UTC birth instant: each body placed on the wheel, retrogrades marked, fixed stars conjunct natal points lit. Deterministic (same birth → same sky). Convert local birth time to UTC before calling. Returns SVG markup. Costs 1 call.
Raw geocentric ecliptic positions for any instant (UTC): 13 bodies (Sun through Pluto, Chiron, lunar nodes) with longitude and retrograde flags. JPL-validated ephemeris (Meeus + Standish 1992). Costs 1 call.
Numerology profile from a birth date (UTC): Pythagorean life path (master numbers 11/22/33 preserved), birthday number, personal year/month/day cycles, and tarot birth card. Time fields are accepted but only the date matters. Costs 1 call.
Composite/connection chart for two people from their UTC birth instants: electromagnetic channels (chemistry), dominance, companionship, and compromise channels, combined definition, and type/authority/profile dynamics. Canonical Energy Blueprint (Human Design) relationship analysis. Costs 1 call.

signature_lookup
Ratified Kairos' Council figure-signature canon (cross-product canon, ratified 2026-07-19): 9 signature templates and 35 carrier figures with template assignment, one-line historical argument, parameterization, and primary forge. Input: `figure` (name or slug) for one figure, or `template` (T1–T9 or name) for a template and all its carriers. Static canon data — deterministic. Costs 1 call.
