Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 543 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name pluto-garden.

  • Pass
    Lists tools

    tools/list returned 3 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 543 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 543 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

  • Not measured
    Free tier cited

    No publisher quote has been checked.

Tools

  • Pass
    Tools described

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

  • Pass
    Parameters documented

    12 of 12 parameters have a description (100%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Fail
    Website matches publisher

    The website host does not match the reverse-domain namespace.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Not measured
    Repo owner matches

    This namespace is not an io.github login, so the owner comparison does not apply.

  • Pass
    Recently updated

    Updated 2026-10-30T04:51:50.664701Z, within 180 days.

Capabilities

Tools 3

birth_chart

Draw an accurate birth (natal) chart: Sun, Moon and rising sign, every planet with sign, degree and house, the angles and the tightest aspects. Works without a birth time (then no rising sign or houses). Returns a link to the person's sky in 3D on Pluto Garden and guide pages for each placement. Pass the place as the person said it; the server looks it up. Convert the time to 24-hour local time at the birth place.

Discovered
famous_chart

Birth chart of a celebrity or famous moment from Pluto Garden's sourced collection (e.g. Billie Eilish, Chappell Roan, Lana Del Rey, Bitcoin, the Moon landing). It only holds birth times the person gave themselves, with the source, so a missing name means no self-reported time is known. Returns the big three, placements, source and page link.

Discovered
sky_now

The sky right now, or at any date and time from 1901 to mid-2100, in depth, from NASA JPL DE440. For every planet, the Sun, Moon, North Node and Lilith: sign and degree, ecliptic longitude and latitude, right ascension and declination (with out-of-bounds), distance, speed, retrograde status and its dates, when it entered its sign and when it leaves, and for planets their elongation from the Sun, phase and whether they are in the morning or evening sky. The Moon's phase, age, distance, next sign change, void-of-course window and next aspects, perigee and apogee; the aspects between the planets now (applying or separating); and a dated list of what comes in the next 30 days (full and new moons with their names, sign changes, retrograde stations, exact aspects). Answers "is Mercury retrograde?" and "what is the Moon in today?". Add a place to get the rising sign and midheaven there, each planet's house, and which planets are above the horizon (altitude and compass direction).
