Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

zodiak.info.pl computes astrology from astronomy: birth charts (planets in signs and houses, ascendant, aspects; also two charts compared, the transits of a day, the Vedic chart, the solar return and Saturn returns; aspects, Moon phase, Chinese sign and four pillars), the planets at any moment, the dates the Sun enters the signs, the Chinese zodiac year and a month of astrological events (moon phases, ingresses, retrogrades, eclipses), and a printable sky map card of a day (a birthday, a birth, a wedding) with a QR code. Good when someone asks for their chart or sign, what the sky is doing on a date, or a gift of the sky on a day. It gives calculations, not predictions or interpretations; each answer has a link to the full result on the site (in Polish), where the traditions are quoted with their sources. Times are local clock times; give the birth time as the clock showed it at the place, the time zone and summer time are applied for you. No account is needed; the data sent is used for the calculation only and not stored.

birth_chart — Birth chart

Advertised by the server during the last successful anonymous check.

Advertised read-only

Computes a natal (birth) chart from the date, local clock time and place of birth: the Sun, Moon, planets, lunar node and Lilith in the signs of the tropical zodiac and in the houses, the ascendant and midheaven, house cusps (Placidus or whole sign), aspects with orbs, the phase of the Moon, the Chinese year sign and the four pillars (BaZi), and how close the ascendant, houses and signs are to changing with the hour. Without a time it gives what does not depend on the hour. The time zone and summer time of the place are applied from the IANA history. Calculations only, no interpretation; the link opens the full result on the site.

sky_at — Planets at a moment

Advertised by the server during the last successful anonymous check.

Advertised read-only

synastry — Synastry of two charts

Advertised by the server during the last successful anonymous check.

Advertised read-only

Compares two birth charts: the aspects between the planets (and ascendant and midheaven when known) of the two people, the most exact first, and each person's planets in the other's houses. Each person is an object with date, time (optional), place (or lat, lon, tz) and name (optional). Calculations only, no reading of the relationship; the link opens the double chart on the site.

Advertised read-only

The planets of a day (today by default) against a birth chart: their houses in it, their aspects to the points of birth, and the exact transits of Jupiter, Saturn, Uranus, Neptune and Pluto to it for twelve months. Calculations only, no forecast.

planet_returns — Saturn and Jupiter returns

Advertised by the server during the last successful anonymous check.

Advertised read-only

When Saturn (about at 29, 59 and 88) and Jupiter (about every 12 years) come back to their places of birth: each return with its dates and the age, three crossings when retrograde motion takes the planet back over the place.

sky_card — Sky map card of a day

Advertised by the server during the last successful anonymous check.

Advertised read-only

Makes a printable card of the sky on a day that matters - a birthday, the birth of a child, a wedding or any day - at a place: the link opens the sky map over that place (at the given hour, or 22:00) with a title, a line, the Moon's phase, sunrise and sunset, the planets, the signs and a QR code of the card, ready to print on A4, A3 or as an A6 greeting card. The answer also lists those facts, eclipses within 15 days, the meteor showers active that night and the NASA picture of the day of that date. Use it when someone wants a gift or keepsake of the night sky on a date.

Coordinates and IANA time zone of a town or city: all places in Poland and world cities over 15 000 people, Polish names first (Londyn and London both work). Use it to check which place birth_chart or sky_at would take, or to pick one of several of the same name and pass its lat, lon and tz.

Connect from your client

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.

Claude Code configuration

claude mcp add --transport http zodiak-info-pl-mcp https://zodiak.info.pl/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).

Codex configuration

codex mcp add zodiak-info-pl-mcp --url https://zodiak.info.pl/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable zodiak-info-pl-mcp in your MCP settings.

Cursor configuration

{
  "mcpServers": {
    "zodiak-info-pl-mcp": {
      "url": "https://zodiak.info.pl/mcp"

    }
  }
}

VS Code

Merge this server into .vscode/mcp.json. Use MCP: List Servers to start zodiak-info-pl-mcp and inspect its tools.

VS Code configuration

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.

Gemini CLI configuration

gemini mcp add --transport http zodiak-info-pl-mcp https://zodiak.info.pl/mcp

Claude Desktop

Open Claude Settings > Connectors > Add custom connector, enter this server URL and enable it for the conversation. This is a manual remote-connector handoff, not a desktop JSON configuration.

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
