MCP server

CSPriceAPI runs a remote Model Context Protocol server, so AI assistants such as Claude, ChatGPT, Cursor and VS Code Copilot can look up live CS2 skin prices themselves instead of guessing.

CSPriceAPI is a CS2 skin price API covering 13 marketplaces, with 45,000+ items and ~5 min live snapshots.

Server URL: https://api.cspriceapi.com/mcp (Streamable HTTP)

Without a key and with a key

	Without a key (preview)	With an API key
`find_items`	✓ (60 searches per hour)	✓
`get_prices`	One item per call, 5 lookups per day per IP, prices from a snapshot up to 6 hours old	Live prices, up to 50 items per call, every market your plan includes
Buy orders, float-ranged prices, history, sales	—	✓ according to your plan

The preview is meant for trying the server and also has a shared daily cap. For real use, add your key: plans are on the pricing page. A free 2-day test key can be created instantly in the #get-testkey channel on the Discord: it covers every endpoint except price history, with sales data limited to the last 24 hours.

Send the key as an x-api-key header or as Authorization: Bearer YOUR_API_KEY. Plan limits and the rate limit (10 requests/second) are the same as for the REST API.

Tools

Tool	What it returns	Plan
`find_items`	Exact `market_hash_name` values for a loose query such as "karambit doppler fn"	Preview
`get_prices`	Lowest listing price, listing count and an approximate USD value on every market, the cheapest market, Steam best ask/bid; Doppler names return every phase	Preview / Basic
`get_youpin_buy_orders`	Best YouPin buy order per item; with `detail` or a float, phase, Fade or tier filter: every order with its float range	Pro / Enterprise
`get_float_ranged_prices`	YouPin lowest price per float range, with phase and Fade %	Pro
`get_price_history`	Daily or hourly price history on one market	Enterprise
`get_recent_sales`	Recent CSFloat, YouPin and Skinport sales with float, pattern and stickers	Enterprise

Prices are in each market's own currency (CNY, EUR or USD). price_usd is an approximate conversion at ECB rates, for comparison only.

Setup

Claude Code

claude mcp add --transport http cspriceapi https://api.cspriceapi.com/mcp \
  --header "x-api-key: YOUR_API_KEY"

Leave out --header to use the preview.

Claude (claude.ai and Claude Desktop)

Settings → Connectors → Add custom connector, URL https://api.cspriceapi.com/mcp. Custom connectors cannot send a key header, so this gives the preview. To use your key in Claude Desktop, add the server to claude_desktop_config.json through mcp-remote:

{
  "mcpServers": {
    "cspriceapi": {
      "command": "npx",
      "args": ["-y", "mcp-remote", "https://api.cspriceapi.com/mcp", "--header", "x-api-key:${CSPRICEAPI_KEY}"],
      "env": { "CSPRICEAPI_KEY": "YOUR_API_KEY" }
    }
  }
}

Cursor

~/.cursor/mcp.json (or .cursor/mcp.json in a project):

{
  "mcpServers": {
    "cspriceapi": {
      "url": "https://api.cspriceapi.com/mcp",
      "headers": { "x-api-key": "YOUR_API_KEY" }
    }
  }
}

VS Code (GitHub Copilot)

.vscode/mcp.json. VS Code asks for the key once and stores it securely:

{
  "inputs": [
    { "type": "promptString", "id": "cspriceapi-key", "description": "CSPriceAPI key", "password": true }
  ],
  "servers": {
    "cspriceapi": {
      "type": "http",
      "url": "https://api.cspriceapi.com/mcp",
      "headers": { "x-api-key": "${input:cspriceapi-key}" }
    }
  }
}

ChatGPT

Settings → Apps & Connectors → enable developer mode → Create, URL https://api.cspriceapi.com/mcp, authentication "No authentication". This uses the preview.

Example prompts

"What does a Karambit Doppler Factory New cost on BUFF163 and YouPin, per phase?"
"Which marketplace is cheapest for an AK-47 Redline Field-Tested right now?"
"Compare the YouPin buy order with the lowest listing for the M4A1-S Printstream Minimal Wear."
"Show the 90-day YouPin price history of the AWP Dragon Lore Factory New."

Notes

Answers come from the same data as the REST API: listings refresh about every 5 minutes, YouPin buy orders about every 30 minutes.
The server is read-only; it cannot buy, sell or touch any marketplace account.
