GG Deals Server

CI

A Model Context Protocol (MCP) server for integrating with gg.deals. Designed for Large Language Models to fetch game prices, historical lows, and bundles.

Installation & Usage

Use npx to run the server instantly in your MCP Client (e.g., Claude Desktop). No cloning required.

claude_desktop_config.json:

{
  "mcpServers": {
    "ggdeals": {
      "command": "npx",
      "args": ["-y", "mcp-server-ggdeals"],
      "env": {
        "GG_DEALS_API_KEY": "your_api_key_here"
      }
    }
  }
}

You can generate your API key at https://gg.deals/settings/ -> Connections -> GG.deals API key.

Available Tools

• search_games: Find a base game ID by title. (Note: This tool queries Steam Store API to retrieve Steam App ID, which is used for all gg.deals api calls).

• get_historical_low: Fetch the all-time lowest price.
• get_game_bundles: Fetch Premium/Deluxe DLC bundles linked to a base game.

• src/index.ts: MCP routing & initialization
• src/api.ts: Shared Axios client & error handling
• src/search.ts: Search logic
• src/prices.ts: Pricing & historical data
• src/bundles.ts: Bundles discovery
