Common questions
Is Cafe MCP safe?
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
What keys or codes does it need?
The registry does not list a required key, though some servers ask you to sign in on first use.
Does it run on my computer or in the cloud?
It runs in the maker’s cloud. Connect over the internet with nothing to install, but what you send passes through the maker’s servers.
Is it still maintained?
The GitHub repo last changed –, and the latest version (1.1.0) reached the registry 20 days ago.
Which apps can use it?
Apps that support MCP, such as Claude Desktop, Claude Code, Cursor and VS Code. It connects by URL, so apps that accept remote MCP servers work too, such as ChatGPT in developer mode.
What can I use instead?
In the same category: Spec Driven Development, Remote Desktop Commander, EmbeddedCI BenchPod

cafe-mcp: Saju & BaZi (Four Pillars of Destiny) MCP server
Korean astrology (Saju, 사주) and Chinese BaZi (八字) for AI agents. Computed, not guessed. Give Claude, ChatGPT, Cursor or any MCP client a birth date and time. cafe-mcp returns the Four Pillars chart, luck cycles, a manseryeok (만세력) calendar and the classical texts as structured, reproducible data from the CAFE engine. Your AI writes the reading in the user's language.
Why not just ask the LLM? A general model improvises the chart: the same birth data gives a different
Day Master on different days, and solar-term boundaries, hidden stems and luck cycles are routinely wrong.
cafe-mcp calculates them with an engine built since 2019: solar terms to the second, birthplace longitude,
historical time zones and daylight saving. Same input, same chart, every time.
Quick start
Server URL:
https://mcp.24plus.ai.kr/mcpclaude.ai, Claude apps, ChatGPT: add a custom connector with the URL above, sign in to 24PLUS, then allow. No key needed.
Claude Code, Cursor and other clients: either add the URL and sign in (OAuth), or create a key at https://24plus.ai.kr/my and send it as a bearer token:
claude mcp add --transport http cafe-mcp https://mcp.24plus.ai.kr/mcp --header "Authorization: Bearer mcp_live_..."{ "mcpServers": { "cafe-mcp": { "url": "https://mcp.24plus.ai.kr/mcp", "headers": { "Authorization": "Bearer mcp_live_..." } } } }Disconnect any time from My account > Connected AI.

Principles
- Calculation is deterministic; interpretation is left to your AI, grounded in the returned data.
- No scores or fixed predictions in the free tools. Levels describe the strength of a tendency.
- Birth data is used only for the calculation. The server keeps a one-way fingerprint for the monthly chart count, never the birth date itself. See PRIVACY.md.
Before v1.1.0
Until 2026-10-18 this URL served an open server with six tools and no sign-in, and the npm package @dangamsoft/cafe-mcp ran it locally over stdio. Both are retired; the npm package is deprecated. See CHANGELOG.md.
