The API is live and you can try it on the free plan. Paid plans launch soon — for now you can join the waiting list.
Human Design, Gene Keys, BaZi, Jyotish, the Matrix of Destiny, numerology, the draconic chart and Western astrology — computed deterministically on the Swiss Ephemeris, in about 120 ms.
Works as a REST API and as an MCP server in Claude, ChatGPT and Cursor.
Computing…You pay for what you use. One bundle computes all eight at once for 6 credits instead of 9 — the discount exists so that calling once beats calling eight times.
Aura type, strategy, inner authority, profile, definition, 9 centres split into defined and open, every channel, 64 gates × 6 lines across 13 bodies in Personality and Design, incarnation cross.

Prokerala, AstrologyAPI and Vedika have no MCP server. This is the one thing on this page the competition doesn't have at all — not a worse version, none.
Paste this into your MCP client's config and swap in your key. That's the whole setup.

What's my Human Design type? I was born on 1 September 1993 at 14:30 in Warsaw.

You're a Manifesting Generator with emotional authority and a 4/6 profile. That means big decisions need to be slept on — clarity arrives after the emotional wave passes, not at its peak…
The model calls resolve_birth_data first, because it has a city name and never coordinates — which is exactly why that's a separate tool. Without it, every flow falls over on the first question.
Credit cost on the right. The bundle costs 6 instead of 9 — price is how you steer what the model picks.

}'The competition sells Western and Vedic astrology. Nobody sells Human Design alongside Gene Keys, BaZi and the Matrix of Destiny in one coherent API — and certainly not as an MCP server.
| Eldermind | Typical API | |
|---|---|---|
| Human Design and Gene Keys | ✓ | ✗ |
| BaZi with Da Yun and the Ten Gods | ✓ | ✗ |
| Matrix of Destiny | ✓ | ✗ |
| Animal Design for pets | ✓ | ✗ |
| MCP server | ✓ | ✗ |
| Eight systems in one call | ✓ | ✗ |
| Self-hosted deployment | ✓ | ✗ |
The engine runs entirely locally on the Swiss Ephemeris, with no third-party API in the execution path. That's also why it can be licensed for on-premise deployment — for customers whose data cannot leave their own infrastructure.

The engine is live and you can try it today on the free plan. Paid plans open once the store clears our payment provider's audit. Leave your address and we'll write on launch day — with the price frozen for the first 50 customers.
For 23 reference birth dates we keep frozen, complete responses from every system. Any engine change that moves a single number fails CI. They were chosen for the places calculations actually break: daylight-saving gaps and overlaps, the polar circles, 29 February, dates before 1900, the 180th meridian. That set caught a real production bug for us.
Enough to test all eight systems and connect the MCP server to Claude. No commitment, no card details.
