CSPriceAPI MCP Server — live CS2 skin prices for AI assistants

CSPriceAPI is the CS2 skin price API for traders who need Chinese markets: live BUFF163 and YouPin prices, YouPin buy orders, Doppler phases and float-ranged prices across 13 marketplaces in one REST API.

This remote Model Context Protocol server lets Claude, ChatGPT, Cursor, VS Code Copilot and other MCP clients look up those prices directly.

Read-only: the server cannot buy, sell or access any marketplace account.
Prices are in each marketplace's own currency (CNY, EUR or USD); price_usd is an approximate conversion at ECB rates.
The same data is available as a REST API: docs, OpenAPI.
