Official MCP servers: openness index — Official MCP servers of major US / Chinese / regional companies (payments, maps, finance data, collaboration, cloud, model platforms): transport, auth barrier, account requirements, pricing model, free quota (doc wording), daily cross-border reachability (China<->US handshake), listing on MCP Registry / Claude directory. Facts only, no scores.
MCP openness change events — Append-only change events of tracked official MCP servers (terms/pricing pages, cross-border reachability, tools, status, directory listing) for the last N days, optionally for one entry id from find_mcp.

Added "list_overseas_listings" (13 tools before, 14 now)
Chinese LLMs on overseas platforms — Where Chinese open models (DeepSeek, Qwen, GLM, Kimi, MiniMax, ...) are listed on platforms headquartered outside mainland China: hosting type, regions, input/output/blended USD per 1M tokens vs the official price, context, tool calling, data-policy links. Labs ranked by Hugging Face followers, models by downloads and likes.

LLM official price history (Pro) — Pro (API key required): daily official list-price history per model since July 2026, USD and RMB per 1M tokens, with source URLs. Filter by model, vendor, country and date range.

Enterprise AI infrastructure cost — Monthly AI cost for 10 / 100 / 1,000 / 10,000-person company samples across industries: API (per-role model choice, or the open model's official API) vs self-hosting the same open model on public cloud, private cloud or on-premises GPUs, with GPU count and cost per 1M tokens.
Token budget per job role — Monthly token usage and cost for 32 common job roles at light / standard / heavy AI usage, with the best model (any country) and the best Chinese model that meet each role's capability floor.
GPU prices and specs — Data-center, workstation and consumer GPUs (B300/B200/H200/H100/H20, Ascend 910B/910C, RTX PRO 6000/5500/5000, RTX 5090/5090D/4090D, L40S/L20): VRAM, bandwidth, FP16 compute, list price, China market price (SXM GPUs per 8-GPU node), cloud rental with 7-day change, sources and dates.
