At a Glance & Executive Verdict
Bazi MCP
Spirituality & Esoterica · Local stdio
Quality: 68/100 (Great) | Auth: No auth required
Quran
Spirituality & Esoterica · Local stdio
Quality: 45/100 (Fair) | Auth: No auth required
Verdict Summary: Choose Bazi MCP if you need specialized Spirituality & Esoterica tools running via a local process. Choose Quran if your workspace requires Spirituality & Esoterica integration with local subprocess execution. Both servers can be configured concurrently in your client's mcpServers manifest.
Which MCP Server Should You Choose?
Choose Bazi MCP when:
You need dedicated capabilities in the Spirituality & Esoterica domain.
You prefer local stdio subprocess transport architecture.
Your security boundary fits: No auth required (Free / Open Source).
Deterministic Bazi / Four Pillars MCP server with True Solar Time, lunar/solar conversion, Da Yun luck cycles, branch interactions, reverse Bazi lookup, and OpenFate calculation metadata. Install: npx -y @openfate/bazi-mcp.
Calculate a deterministic OpenFate Bazi/Four Pillars chart with True Solar Time correction, Day Master, DAYUN_SECOND_V2 onset receipts, Da Yun cycles, and branch interactions. Pass an exact birth time plus timezone or timezoneId for a calculated V2 onset; otherwise inspect the explicit unavailable/fallback receipt.
detect_bazi_interactions
Detect raw Earthly Branch relationship occurrences for a natal chart and optional annual and Da Yun branches. Preserves every matching pillar position, including repeated branches. Covers clashes, six-combinations, the eight central-branch half-trines (COMBINATION_HALF), full trines, directionals, punishments, destructions, and harms. Results establish relationship presence, not weights, cancellation, or automatic transformation; targetElement is an affinity, not transformed energy.
calculate_true_solar_time
Calculate OpenFate True Solar Time from civil birth time, longitude, timezone, and optional DST offset. Use this when explaining why the hour pillar may differ from ordinary clock-time tools.
reverse_bazi_to_solar_times
Find possible Gregorian datetimes that produce a given four-pillar Bazi string. This is useful when a user only has a Bazi chart or screenshot. This lookup uses clock-time pillars without location-based true solar correction.
Ready-to-Paste Client Configurations
Paste either (or both) of these JSON server blocks into your client config file (e.g. claude_desktop_config.json or ~/.cursor/mcp.json).
Bazi MCP is categorized under Spirituality & Esoterica and uses a local stdio subprocess. In contrast, Quran belongs to Spirituality & Esoterica using local stdio subprocess. Select Bazi MCP when you need capabilities focused on spirituality & esoterica and Quran when you require tools for spirituality & esoterica.
Return OpenFate calculation policy and LLM guidance for Bazi chart calls.
get_openfate_bazi_resources
Return canonical OpenFate URLs for charting, readings, compatibility, wealth, true solar time, and AI crawler metadata.
Quran Tools (4)
list_surahs
List all 114 surahs (chapters) of the Quran with their Arabic name, English name, English translation, ayah (verse) count, and revelation type (Meccan/Medinan).
get_surah
Get the full text of a surah (chapter) of the Quran by its number (1-114). Returns every ayah (verse) in the chosen edition. Use an English translation edition (e.g. en.asad, en.sahih) for English, or quran-uthmani for the Arabic text.
get_ayah
Get a single ayah (verse) of the Quran by reference — either surah:ayah (e.g. "2:255" for Ayat al-Kursi) or a global ayah number (1-6236). Returns the verse text in the chosen edition (translation like en.asad / en.sahih, or Arabic via quran-uthmani).
search_quran
Search the Quran for a keyword across ayahs (verses). Returns matching verses (up to 30) with their surah (chapter) and ayah number. Defaults to the en.asad English translation; pass another edition to search a different translation or Arabic (quran-uthmani).
