Does this server send my data to a remote server?

No. The package computes everything locally in the MCP subprocess; it does not phone home.

What runtime does it require?

Node.js is required. Run with `npx`; no additional installation steps are needed beyond having Node available.

What is the Openfate Bazi MCP Server?

OpenFate Bazi MCP server with deterministic Four Pillars calculation, True Solar Time, branch interactions, and reverse Bazi lookup.

What it actually does

OpenFate Bazi MCP is a Model Context Protocol server for accurate Bazi / Four Pillars calculation inside AI agents such as Claude Desktop, Cursor, Cline, and Continue.

24 solar-term boundaries
True Solar Time
longitude and timezone correction
Zi-hour day-boundary rules
lunar-to-solar conversion
branch interactions

Example prompts to try

“Use Openfate Bazi MCP to calculate bazi chart.”
“Use Openfate Bazi MCP to detect bazi interactions.”
“Use Openfate Bazi MCP to calculate true solar time.”

Frequently asked questions

LLMs should not manually calculate Bazi charts. The difficult parts (solar terms, True Solar Time, timezone corrections, DST, Zi‑hour rules, lunar‑solar conversion, branch interactions) are deterministic and better handled by a dedicated engine.
