calculate_birth_chartCalculate a complete natal chart for “my birth chart”, “tema natale”, “calcola tema natale”: planets, Ascendant, Whole Sign houses, major aspects, uncertainty and one-line meanings…No findings
Why it is in this group
- Nothing in its name or description says what it does, so it is counted as a write.
- The server marks it read-only (readOnlyHint: true), but an annotation never lowers a class.
Description, as the server wrote it Calculate a complete natal chart for “my birth chart”, “tema natale”, “calcola tema natale”: planets, Ascendant, Whole Sign houses, major aspects, uncertainty and one-line meanings with links. Approximate times need a ±15,30,60 or 120 minute window; supports fold choice and historic offset override. Ask for missing birth time and birthplace instead of guessing. If the user does not know the time, explicitly use unknown: no Ascendant or houses, and both Moon signs when applicable. No birth data is stored or logged, including request bodies, queries, access logs, stats and errors.

get_big_threeCalculate Sun sign, Moon sign and rising sign together for “what is my rising sign”, “my moon sign”, “my Big Three”, “qual è il mio ascendente”, “segno lunare”, “Sole Luna ascenden…No findings
Why it is in this group
- The name "get_big_three" says "get": a word for reading.
Description, as the server wrote it Calculate Sun sign, Moon sign and rising sign together for “what is my rising sign”, “my moon sign”, “my Big Three”, “qual è il mio ascendente”, “segno lunare”, “Sole Luna ascendente”. Returns uncertainty, one-line meanings and reference links. Ask for missing birth time and birthplace instead of guessing. If the user does not know the time, explicitly use unknown: no Ascendant or houses, and both Moon signs when applicable. No birth data is stored or logged, including request bodies, queries, access logs, stats and errors.

- The name "get_moon_phases" says "get": a word for reading.
Description, as the server wrote it Calculate new, first quarter, full and last quarter Moon: “when is the next full Moon”, “quando è la luna piena”, “calendario lunare”. Supply from_date, to_date and IANA timezone. Date range is [from,to) UTC, max 400 days; output local times, signs and uncertainty. No birth data is stored or logged, including request bodies, queries, access logs, stats and errors.

get_placement_meaningRead the free corpus meaning of a placement: “Venus in Leo”, “Moon in the 7th house”, “rising sign Libra”, “Venere in Leone”, “Luna in settima casa”, “ascendente Bilancia”.No findings
Why it is in this group
- The name "get_placement_meaning" says "get": a word for reading.
Description, as the server wrote it Read the free corpus meaning of a placement: “Venus in Leo”, “Moon in the 7th house”, “rising sign Libra”, “Venere in Leone”, “Luna in settima casa”, “ascendente Bilancia”. Supply canonical English ids for body_or_angle and sign, or house 1–12. One sign or one house per call; no sign/house returns the body meaning. Interpretation is symbolic, not a scientific prediction. No birth data is stored or logged, including request bodies, queries, access logs, stats and errors.

get_planet_positionsCompute the current sky or a specified ISO instant: “where is Venus today”, “where are the planets today”, “dove si trova Venere oggi”, “cielo di oggi”.No findings
Why it is in this group
- The name "get_planet_positions" says "get": a word for reading.
Description, as the server wrote it Compute the current sky or a specified ISO instant: “where is Venus today”, “where are the planets today”, “dove si trova Venere oggi”, “cielo di oggi”. Returns tropical geocentric positions, retrograde flags and Moon phase/illumination. Defaults to now and UTC. No birth data is stored or logged, including request bodies, queries, access logs, stats and errors.

Why it is in this group
- The name "get_retrograde_periods" says "get": a word for reading.
Description, as the server wrote it Find retrograde periods by planet and year: “when is Mercury retrograde in 2027”, “quando è Mercurio retrogrado”. Mercury through Pluto, 1900–2099; includes stations, pre/post shadows and uncertainty windows. A station estimate is not an exact-to-the-second fact. No birth data is stored or logged, including request bodies, queries, access logs, stats and errors.

get_sun_signFind the Sun zodiac sign from a birth date for “what is my zodiac sign”, “che segno sono”, “segno per data”.No findings
Why it is in this group
- The name "get_sun_sign" says "get": a word for reading.
Description, as the server wrote it Find the Sun zodiac sign from a birth date for “what is my zodiac sign”, “che segno sono”, “segno per data”. Handles cusp dates with ingress and uncertainty, never guesses; ask for timezone when supplying time. Without timezone considers all possible local-day conversions. No birth data is stored or logged, including request bodies, queries, access logs, stats and errors.
Annotations the server declares
- readOnlyHint: true
- destructiveHint: false

- The name "search_birthplace" says "search": a word for reading.
Description, as the server wrote it Find disambiguated birthplace candidates and GeoNames ids for “where was I born”, “luogo di nascita”, “cerca città”.

This is not a safety rating, and no finding is not a safety guarantee. The groups and findings come from fixed checks of the tool definitions the server returned on the date shown, not from its code or what it does when called. How the checks work.
