Unmeasured means there is not enough evidence to decide. How these checks work

Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 96 ms.

  • Pass
    Valid handshake

    protocolVersion 2025-11-25, serverInfo.name sky-keepsake.

  • 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 96 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 96 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

    21 of 21 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.

  • Not measured
    Website matches publisher

    This namespace is not a reverse domain, so the website comparison does not apply.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Fail
    Repo owner matches

    The GitHub repository owner does not match the namespace login.

  • Pass
    Recently updated

    Updated 2026-10-22T05:47:51.953908Z, within 180 days.

Capabilities

Tools 3

find_moon_phase

Use this when the user asks what the moon looked like on a date (birthday, wedding, first date), the moon phase today or tonight, whether two people's birthday moons complete each other ("our moons make a full moon"), or wants a moon phase calendar for a month. Returns phase name, illumination %, moon age, waxing/waning, exact phase times and the next full and new moon, computed with astronomical algorithms. Does not give astrology readings, tides or moonrise times. Do not use for planets or eclipses.

Discovered
generate_moon_poster

Use this when the user wants a printable moon phase poster: the moon on one special date, two dates side by side ("our moons" couple print), or a lunar calendar of a whole year. Computes the real phases and returns a preview plus vector PDFs (12x18 in, 18x24 in, A3, Letter, A4) and SVG. Does not sell or ship prints. Do not use for a quick phase answer without a poster; that is find_moon_phase.

Discovered
generate_star_map

Use this when the user wants a star map or night sky poster for a date and place: the sky over a city on a birthday, wedding, anniversary or the night they met, or the sky tonight. Computes the real positions of about 2,900 stars, constellation lines and the Moon for the city's local time (time zones and DST handled) and returns a preview plus vector poster PDFs (12x18 in, 18x24 in, A3, Letter, A4) and SVG. Takes a city name, not coordinates. Does not draw planets and is not for navigation or telescope pointing.
