Overview

AI-generated overview

Lets an assistant look up live CS2 skin prices, buy orders and price history across 13 marketplaces, including BUFF163 and YouPin.

What it does
A remote MCP server for CS2 (Counter-Strike 2) skin market data. Tools include find_items for resolving loose queries to exact market_hash_name values, get_prices for lowest listing prices, listing counts and approximate USD values across marketplaces such as BUFF163, YouPin898, Skinport, CSFloat and Steam, get_youpin_buy_orders for YouPin buy orders with float range, phase and Fade or Case Hardened tier, get_float_ranged_prices, get_price_history and get_recent_sales. Doppler names return every phase, and prices are reported in each marketplace's own currency.
When to use it
Useful when comparing skin prices across markets, checking which marketplace is cheapest for a specific item, inspecting YouPin buy orders against listings, or reviewing price history and recent sales. It suits traders and analysts who need Chinese market coverage alongside Western marketplaces.
Requirements
A remote Streamable HTTP endpoint; no local install. An API key sent as the x-api-key header (or Authorization: Bearer) unlocks live prices, up to 50 items per call and the higher-tier tools. Without a key, find_items and get_prices work as a free preview limited to one item per call, 5 lookups per day, with prices up to 6 hours old. Some clients, such as claude.ai custom connectors, cannot send a key header.
Before you install
The x-api-key header is a secret and should be supplied through the client's environment or prompt mechanism rather than pasted into shared configuration. Access tiers are plan-based, so some tools require a paid plan. The server is described as read-only and cannot buy, sell or access marketplace accounts. Price data comes from third-party marketplaces and USD values are approximate conversions.
