Core

  • Pass
    Reachable

    Latest probe returned HTTP 200 in 481 ms.

  • Pass
    Valid handshake

  • Pass
    Lists tools

    tools/list returned 11 tools.

  • Pass
    Current protocol

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

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 481 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 481 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.

  • Fail
    Parameters documented

    21 of 28 parameters have a description (75%). The bar is 80%.

  • Fail
    Safety hints

    11 tools set neither readOnlyHint nor 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 2026-10-22T00:15:27.419901Z, within 180 days.

Capabilities

Tools 11

calendar

Chinese calendar for a date: lunar date (with leap month), zodiac, day officer 建除, yellow/black path, six-day cycle — computed on Beijing time

Discovered
flying_star_chart

Xuan Kong flying star natal chart: nine palaces with mountain/facing/period stars plus classical pattern labels (e.g. 旺山旺向). Period from a construction date, or explicit yun

Discovered
form_analysis

Indoor form-sha from a floor-plan wireframe: 穿堂煞 (door-window alignment), 缺角 (nine-palace missing corners), 厕占中宫 (toilet at centre) — plus optional fusion with the Eight Mansions house stars and Ming Gua. Grade B verdicts, no aggregate score

Discovered
ganzhi

Four pillars (BaZi) for a date+hour, returned under BOTH year conventions (Lichun vs Lunar New Year) × BOTH day boundaries (midnight vs 23:00) — differences are shown, not hidden

Discovered
kua_number

Ming Gua (Kua number) from birth date + gender, with the Lichun year boundary computed astronomically, five-yellow substitution conventions, and eight favourable/unfavourable directions

Discovered
replay

Verifiability as an API call: recompute a stored request and compare its SHA-256 input digest (JCS-canonicalised) against an expected value — byte-identical reproduction or honest mismatch

Discovered
rulesets

List the rule sets the kernel actually implements, with parameters and honest review_state — nothing not implemented is advertised

Discovered
solar_terms

All 24 solar terms of a year with exact Beijing instants. Model: VSOP87D apparent solar longitude + nutation + aberration + ΔT; root tolerance 1e-7 day (~8.6 ms); verified against an independent JPL DE441-based reconstruction. ΔT and midnight-margin uncertainty flags included.

Discovered
sun_position

Sun azimuth/elevation for a location and instant (solar compass numeric base): azimuth 0=north clockwise, geometric vs apparent (Sæmundsson refraction) elevation, declination, hour angle, explicit polar day/night state — measurement link only, no direction is inferred from photos

Discovered
terrain_white_tiger

White tiger elevation check (白虎抬头) from a DEM-derived 360-bin skyline: compares the right (white tiger) vs left (azure dragon) sector elevation within ±45° of the sitting direction

Discovered
yun_period

San Yuan period (三元九运, 1–9) for a date; periods switch at Lichun, anchored 1984 = start of Period 7
