What it does
Naelos.ai is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.
No capability identified yet from its description.
Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence). None of this is a test of the tool.

10 tools offered to AI assistants
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.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.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.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. Majosynastry· The aspects between two people's birth charts (each one's planets to the other's), with exact orbs and strength.returns· 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.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).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.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.
What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method
Is this your server? Monitoring Pro: a check every 30 minutes and an email within the hour when it stops answering. Launch offer: $39.99 once, for life.
