Legend Saju does not always answer
Over the last week it answered 0.0% of our checks. We check every 15 minutes, so you hear about the next outage within the hour — not from your users.

If a tool disappears, we record the date.
legend
legend_saju_analyze_compatibility
Use this when the user asks 궁합, 결혼 가능성, relationship compatibility, or wants two birth charts compared. Requires both people's birth data.
legend_saju_analyze_name
Use this for 작명, 성명학, 81수, 이름 한자, 인명용 한자, 획수, or 파자 questions. It keeps legal Hanja observations, declared stroke standards, and birth-based naming guidance separate.
legend_saju_capabilities
Use this when a user asks which Saju, Myeongri, Zi Wei, Qimen, Daliuren, I Ching, Tieban, Dang Saju, Tojeong, Feng Shui, naming, dream, or other traditional calculation method fits a specialized question. Do not use it for an ordinary fortune reading.
legend_saju_card_compatibility
Render a two-person compatibility card (사주 궁합 봐주세요). Shows both day pillars and deterministic 합·충·형·파·해 signals. Compute chart facts server-side and render them in a widget card. Write the narrative/text fields yourself, grounded in a prior legend_saju_read_fortune call — the card labels them as AI interpretation. After the card renders, add only brief text the card does not already show.
legend_saju_card_fortune
Render domain fortune cards (재물운·연애운·결혼운·직업운·건강운·학업운·이동운·재회운·총운). Pick only the domains the user asked about and write each card's text yourself. Compute chart facts server-side and render them in a widget card. Write the narrative/text fields yourself, grounded in a prior legend_saju_read_fortune call — the card labels them as AI interpretation. After the card renders, add only brief text the card does not already show.
legend_saju_card_natal
Render a natal-chart card (사주 봐주세요·원국 풀이·신살 질문). Shows four pillars, day-master identity, element balance, 왕쇠·격국·용신 verdicts, 신살, and 합충. Compute chart facts server-side and render them in a widget card. Write the narrative/text fields yourself, grounded in a prior legend_saju_read_fortune call — the card labels them as AI interpretation. After the card renders, add only brief text the card does not already show.
legend_saju_card_timeline
Render the 대운 flow timeline (대운 흐름·결혼 시기·이직/창업 시기 질문). Marks the current 대운 and an optional focus year with its 세운. Compute chart facts server-side and render them in a widget card. Write the narrative/text fields yourself, grounded in a prior legend_saju_read_fortune call — the card labels them as AI interpretation. After the card renders, add only brief text the card does not already show.
legend_saju_cast_divination
Use this for 기문둔갑, 대육임, 주역, 점괘, or a concrete decision cast from a question time or six line values. Do not use it for a general natal fortune reading.
legend_saju_interpret_dream
Use this for 해몽, 꿈풀이, or dream interpretation. It currently handles five cross-culturally audited concepts and returns both shared motifs and conflicting conditions with primary-source excerpts; it does not turn the remaining raw corpus into invented meanings.
legend_saju_manifest
Return the live, source-traceable deterministic engine manifest. No model or network call.
legend_saju_read_fortune
Use this for natal, current, annual, career, wealth, relationship, health, and action readings. Use detailLevel for calculation breadth and outputMode for action, readable, evidence, or debug results. Consumer responses always carry verdicts (왕쇠·격국·용신 후보 conclusions) plus an evidenceIndex of omitted internal claims; repeat the identical call with claimIds from that index to selectively pull deeper grounding such as strength axes, pattern structure, or methodology notes.
legend_saju_run_methods
Use this for expert, mixed-system, or named-method requests. It covers Myeongri details such as 십성·지장간·투간·통근·합충형파해·삼합·방합·육합·월령·격국·조후·억부·통관·병약·궁통보감·적천수·삼명통회·연해자평·종격·화격·특수격; Zi Wei 12궁·삼방사정·대한·유년·유월·유일·유시·생년사화·궁간사화·자화·비성·흠천사화·중주파; and Qimen, Daliuren, I Ching, Tieban, Dang Saju, Tojeong, Feng Shui, naming, 81-number, Hanja decomposition, and dream traditions. Pass discovered capability IDs together in requestedCapabilities, or let the server plan from the question. Use focused tools for ordinary single-goal requests.
legend_saju_select_dates
Use this only when the user explicitly asks for 택일, 좋은 날, 계약일, 이사일, 개업일, 수술일, or another date-selection task. Do not use it merely because a fortune request mentions this year.

Legend Saju — questions
Answers built from our own checks of this server.
What can Legend Saju do?
It exposes 13 tools, read directly from the server on our last check. Among them: legend_saju_analyze_compatibility, legend_saju_analyze_name, legend_saju_capabilities, legend_saju_card_compatibility, legend_saju_card_fortune, legend_saju_card_natal and 7 more. The full list with descriptions is on this page — we take it from the server itself via tools/list, not from a README.
How MCP servers expose tools in the first place →
Is Legend Saju working right now?
We send a real MCP handshake every 15 minutes. Over the last 24 hours 0 of 92 checks got a reply (0.0%), average response time 353 ms. The bar chart above shows every period we have measured.
The registry lists Legend Saju as active — why does it not respond?
The official MCP registry stores what the author submitted; it does not verify that the server still runs. We check the endpoint ourselves, and this one does not answer. Catalogues that copy the registry without checking will show it as working.
How do I connect Legend Saju?
Copy the ready config from this page. We generate it for Claude Code, Claude Desktop, Codex, Cursor and VS Code, each in the form that client actually reads. It is a remote server, so there is nothing to install — the client connects to the address.
Does Legend Saju need an API key?
No. Legend Saju completed a full MCP handshake with us as an anonymous client and listed its tools without asking for anything. All 13 of them are readable on this page. This is what we observed, not what the docs claim.
Is Legend Saju open source?
The code is open source: it is published under the Apache-2.0 licence, written in TypeScript and 0 stars on GitHub. The licence covers the code in the repository, not the hosted service at legend-saju-mcp-production.up.railway.app, which runs on its operator's own terms.
