- pass `tools.token_cost`: about 2,849 tokens to load every tool
- pass `tools.api_dump`: tools are not a one-to-one API dump
- pass `tools.hidden_text`: no hidden text in tool names, descriptions, schemas or annotations

### stability: 83 (weight 15)

- warn `stability.changes`: 11 tool changes in 30 days
- pass `stability.rug_pull`: no tool changed its meaning under the same name
- pass `stability.new_links`: no tool change named a new site

### dependencies: n/a (weight 15)

- n/a `deps.known_vulns`, `deps.mcp_sdk_version`, `deps.resolvable`: no npm or PyPI package

- Checks run on what our credential-free, read-only probes observe; tools are never called and no code audit is performed.

### Tool changes

- 2026-11-03 `returns` changed (description)
  - before: The solar return for a year (the moment the Sun returns to its birth position, the chart for that year) or the lunar return nearest now, cast for the birthplace or another location.
  - after: The solar return for a year (the moment the Sun returns to its birth position, the chart for that year) or the most recent lunar return (the last time the Moon reached its birth position), cast for the birthplace or another location.

## Tools (10)

- `eclipses`: Solar and lunar eclipses between two dates (up to 20 years per call), with type, the exact moment of greatest eclipse and the eclipse degree. Works across the full 15,000-year span.
- `naelos_library`: Which national charts (198) and empire charts (19) Naelos holds, each researched and sourced, with the founding event it is cast for. The charts themselves, with their times, places and readings, are in Naelos's Mundane suite.
- `natal_chart`: A complete natal (birth) chart: every planet's sign, degree and house, the Ascendant and Midheaven, retrogrades, and the aspects between planets with exact orbs. Calculated from NASA JPL data by Naelos Ephemeris.
- `planet_position`: One body's tropical position on a date, anywhere from 13,200 BC to AD 17,191, with its speed and whether it is retrograde. For historical and ancient dates; dates before 1582 are proleptic Gregorian.
- `progressions`: The progressed chart as of today: secondary progressions (a day after birth for each year of life) or solar arc directions (every point moved by the Sun's progressed arc).
- `returns`: The solar return for a year (the moment the Sun returns to its birth position, the chart for that year) or the most recent lunar return (the last time the Moon reached its birth position), cast for the birthplace or another location.
- `sky_now`: Where every planet is at a moment (now by default): sign, degree, retrograde, and the aspects between them. Give a place to add houses and angles. Works for any date from 13,200 BC to AD 17,191.
- `synastry`: The aspects between two people's birth charts (each one's planets to the other's), with exact orbs and strength.
- `timing_events`: Between two dates: planets changing sign, new and full Moons (and quarters), and retrograde and direct stations, each with its exact moment in UTC. At most two years per call.
- `transits`: Every exact transit of the planets (Sun to Pluto; the Moon is left out as it aspects everything monthly) to a birth chart's planets, Ascendant and Midheaven over a span, with the exact date of each and whether the planet is retrograde. Major aspects: conjunction, sextile, square, trine, opposition.
