Architecture

The MCP server fetches a data snapshot from jktjj.com/api/x402/data-snapshot on boot and refreshes it every 5 minutes. All tools query from this in-memory snapshot — no direct data file access at runtime.

jktjj.com/data/*  →  /api/x402/data-snapshot  →  mcp Worker (in-memory cache)  →  MCP tools
