- An AI judge read all 7 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Unverified: 1 category
A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
annual_profection Annual profection ~371
Hellenistic annual profection for an age or a date: the profected house (whole-sign, counted from the Ascendant; from the Sun's sign if the birth time is unknown), its sign, the lord of the year (traditional ruler, with the modern co-ruler) and where that lord sits in the natal chart, plus the dates the profection year runs.
| Name | Type | Req | Description |
|---|---|---|---|
| age | integer | – | Age in completed years. Takes precedence over `on_date`. |
| city | string | – | Optional shortcut: a city from the built-in offline table (about 110 large cities, English or Chinese name, e.g. "Beijing", "上海", "London", "New York"). Explicit latitude/longitude/timezone override… |
| date | string | yes | Birth date (local calendar date), YYYY-MM-DD |
| house_system | string | – | House system. Placidus (default) falls back to whole-sign inside the polar circles, where it has no solution. |
| latitude | number | – | Birthplace latitude in degrees, north positive |
| longitude | number | – | Birthplace longitude in degrees, east positive (New York is about -74.0) |
| on_date | string | – | Date to find the profection year for, YYYY-MM-DD (default: today in the birth time zone) |
| time | string | – | Local clock time of birth, 24-hour HH:MM. Omit if unknown: planets are then cast for local noon and there are no Ascendant, Midheaven or houses. |
| timezone | string | – | IANA time zone of the birthplace, e.g. "Asia/Shanghai", "America/New_York". Historical daylight saving time is applied automatically. Required unless `city` is given. |
No output schema declared.
No examples provided.
mercury_retrograde Mercury retrograde ~141
Mercury retrograde periods overlapping a date range (default: the next 12 months): pre-shadow start, station retrograde, station direct and post-shadow end (to about a minute, in UTC and a chosen time zone), with the degrees and signs of the two stations.
| Name | Type | Req | Description |
|---|---|---|---|
| end_date | string | – | End of the range, inclusive, YYYY-MM-DD (default: one year after the start). At most 30 years. |
| start_date | string | – | Start of the range, YYYY-MM-DD (default: today) |
| timezone | string | – | IANA time zone for the range and the local times in the output (default UTC) |
No output schema declared.
No examples provided.
moon_phase Moon phase ~115
The Moon's phase at a moment (default: now): phase name, illuminated fraction, Sun–Moon angle, days since new moon, the Moon's and Sun's signs, and the next new, first-quarter, full and last-quarter moons.
| Name | Type | Req | Description |
|---|---|---|---|
| date | string | – | Date, YYYY-MM-DD. Omit for the current moment. |
| time | string | – | Local time, HH:MM (default 12:00 when a date is given) |
| timezone | string | – | IANA time zone (default UTC) |
No output schema declared.
No examples provided.
natal_chart Natal chart ~317
Cast a tropical natal (birth) chart: the ten planets with sign, degree, house and retrograde flag; Ascendant and Midheaven; twelve house cusps (Placidus by default); major aspects with orbs and applying/separating; and the dominant element and modality. Works without a birth time (no angles or houses then).
| Name | Type | Req | Description |
|---|---|---|---|
| city | string | – | Optional shortcut: a city from the built-in offline table (about 110 large cities, English or Chinese name, e.g. "Beijing", "上海", "London", "New York"). Explicit latitude/longitude/timezone override… |
| date | string | yes | Birth date (local calendar date), YYYY-MM-DD |
| house_system | string | – | House system. Placidus (default) falls back to whole-sign inside the polar circles, where it has no solution. |

No examples provided.
synastry Synastry ~100
Compare two natal charts: the major aspects between person A's planets (and Ascendant) and person B's, with orbs (conjunction/opposition 6°, square/trine 5°, sextile 3°), where each person's planets fall in the other's houses, and a simple descriptive tally (not a compatibility score).
| Name | Type | Req | Description |
|---|---|---|---|
| person_a | object | yes | First person's birth data |
| person_b | object | yes | Second person's birth data |
No output schema declared.
No examples provided.
transits Transits ~193
Planet positions for a date and time (default: now), and, given a natal chart, the major aspects the transiting planets make to the natal planets, Ascendant and Midheaven within an orb (default 2°), with the natal house each transiting planet is passing through.
| Name | Type | Req | Description |
|---|---|---|---|
| date | string | – | Date of the transits, YYYY-MM-DD. Omit for the current moment. |
