Qimena MCP

A free, public MCP server that provides Qi Men Dun Jia chart casting, BaZi Four Pillars calculation, auspicious time ranking, and solar term listing for AI assistants. It uses the same engine as the Qimena website, requires no authentication or API key, and performs calculations only without storing user data.

Endpoint and access

No sign-in to connect and list tools. Individual tools may still need a vendor account, credentials, or permissions; check the documented prerequisites.

Server-provided instructions

Untrusted server output shown for inspection. It is not Koskamo guidance and is excluded from knowledge search.

Deterministic Chinese metaphysics calculations. Use qimen_chart for a Qi Men Dun Jia chart of a moment (now by default), bazi_pillars for Four Pillars from a birth time, best_times to rank the coming double-hours for a goal, and solar_terms for the 24 solar-term instants of a year. Times are wall-clock times in an IANA time zone. Results are for cultural and reference use, not professional advice.

qimen_chart — Qi Men Dun Jia chart
Advertised by the server during the last successful anonymous check.
Advertised read-only

Cast an hour-based Qi Men Dun Jia (奇门遁甲) chart for a moment and place: four pillars, ju, Chief Star and Door, and for each of the nine palaces the deity, star, door, heaven/earth/hidden stems, void, horse star, punishment and door pressure, plus detected patterns, palace scores for the chosen focus and the lucky directions.

bazi_pillars — BaZi Four Pillars
Advertised by the server during the last successful anonymous check.
Advertised read-only

Four Pillars (八字) for a birth moment: converts the clock time with the zone rules for that date (daylight saving included) and the longitude to true solar time; the year follows Li Chun and the day changes at 23:00 true solar time. Returns the pillars, Day Master, five-element counts and the time conversion details.

best_times — Best upcoming double-hours
Advertised by the server during the last successful anonymous check.
Advertised read-only

Cast a Qi Men chart for every double-hour of the next few days and rank them for a goal, using the person's Day Master from the birth date. Returns the top windows with date, hour branch, true-solar-time range, score and the lucky direction at that time.

Each snippet registers the same endpoint; pick the client you use.

This server is operated by the named third party. Listing and endpoint checks are not an endorsement or a security audit. Review the operator's permissions, terms, and data handling before connecting. How listings are checked and corrected.

Claude Code

Run this once in a terminal. It registers the remote server. Use --scope project to write .mcp.json for the repo.
Claude Code configuration
claude mcp add --transport http qimena-mcp https://qimena.com/mcp

Codex

Run this once. Codex stores MCP servers in ~/.codex/config.toml (or .codex/config.toml in a trusted project).
Codex configuration
codex mcp add qimena-mcp --url https://qimena.com/mcp

Cursor

Merge this server into .cursor/mcp.json in your project, then enable qimena-mcp in your MCP settings.
Cursor configuration

Gemini CLI

Run this once. It writes .gemini/settings.json in the current project; pass --scope user for ~/.gemini/settings.json.
Gemini CLI configuration
gemini mcp add --transport http qimena-mcp https://qimena.com/mcp

Claude Desktop

Merge this into claude_desktop_config.json (macOS: ~/Library/Application Support/Claude/, Windows: %APPDATA%\Claude\), then restart Claude Desktop.

Windsurf

Merge this into ~/.codeium/windsurf/mcp_config.json, then refresh MCP in Cascade. Windsurf remote servers use serverUrl, not url.
Windsurf configuration
