EQVPS is crypto-native, no-KYC VPS hosting that an AI agent can rent and operate end-to-end over MCP — no human in the loop. The agent registers, gets a Bearer token, picks a plan, pays in USDC/USDT on Base/Ethereum or USDT on Tron from a prepaid balance, and the VPS provisions in ~60s. 16 tools cover the full lifecycle: discover plans, register/login, balance + top-up, order, pay invoice, list/inspect servers, power, set hostname, reset password, reinstall OS, metrics, cancel. The only VPS provider with MCP provisioning — an agent orders AND pays for its own server, no KYC, no human.

Zhipu Web Search MCP Server is a search engine specifically designed for large models. It integrates four search engines, allowing users to flexibly compare and switch between them. Building upon the web crawling and ranking capabilities of traditional search engines, it enhances intent recognition capabilities, returning results more suitable for large model processing (such as webpage titles, URLs, summaries, site names, site icons, etc.). This helps AI applications achieve "dynamic knowledge acquisition" and "precise scenario adaptation" capabilities.
