The Tarotari MCP server

A public Model Context Protocol server: an assistant connects by URL and receives our data through a tool call rather than by paraphrasing a page. No install, no keys, no registration.

How to connect

In any client that supports remote MCP servers, add a new server and paste the address. The transport is Streamable HTTP, which is the default nearly everywhere.

https://www.tarotari.com/api/mcp

If your client asks for a config file

{
  "mcpServers": {
    "tarotari": {
      "type": "http",
      "url": "https://www.tarotari.com/api/mcp"
    }
  }
}

What it can do

• tarot_cardTarot card meaning

  The meaning of a single Rider-Waite card: upright and reversed, arcanum, suit, links to the image and the page. Looks up by slug (major-00, cups-07) or by Russian name.

• tarot_deckThe full deck

  All 78 cards of the Rider-Waite deck with upright and reversed meanings. Can be limited to a group: major, wands, cups, swords, pentacles.

• tarot_drawDraw a spread

  Draws cards from the deck without repeats, in upright and reversed positions. With a seed the output is deterministic: the same seed gives the same spread.

• tarot_birth_cardTarot birth card

  The personal major arcanum from a birth date: the digits of the date summed and reduced to 1-22. The classic Tarot Birth Card calculation.

• planet_positionsPlanetary positions

  Ecliptic longitudes of ten planets for a given moment: sign, degree within the sign, retrograde status. Computed from VSOP87 ephemerides rather than read from tables.

• moon_stateState of the Moon

  Moon phase, illumination, lunar day, sign and degree for a given moment. Illumination and the lunar day are counted from the real Sun-Moon conjunction, not from the mean synodic formula, which is off by hours and, near midnight, by a whole lunar day.

• aspect_exact_timeExact moment of an aspect

  Finds the moments when two planets form an exact angle: conjunction, sextile, square, trine or opposition. Steps through positions and refines by bisection, accurate to the minute. The same method yields new moons, full moons and sign ingresses, for which mean formulas are unfit.

• natal_chartBirth chart

  A full birth chart for a date, time and place: planetary positions, house cusps, aspects with orbs, the balance of elements and modalities, and major configurations.

How this differs from ready-made tables

• — Planetary positions are computed from VSOP87 ephemerides for any minute you ask for, rather than read from a precomputed calendar.
• — The exact moment of an aspect is found by stepping through positions and refining by bisection. The answer is accurate to the minute and identical worldwide — only the time-zone label changes.
• — Lunar illumination and the lunar day are counted from the real Sun-Moon conjunction. The mean synodic formula used by most calendars is off by hours, and near midnight by a whole lunar day.
• — Card meanings are returned as reference data for interpretation. They are material for a conversation, not a prediction of events.

Check it without a client

A plain GET on the same address returns the server description and the tool list:

curl https://www.tarotari.com/api/mcp

Limits

The server only reads and computes: it stores no requests, requires no payment and exposes no tool that changes anything. Aspect search is capped at a 400-day window per call, a spread at fifteen cards. The server neither receives nor asks for user data.
