steam-storefront-mcp

An MCP (Model Context Protocol) server that gives AI assistants access to public Steam Storefront metadata, official genres, categories, and player review sentiment via structured Steam Storefront JSON APIs.

Search for games on Steam, retrieve official store details, and analyze Steam player review ratings — all without needing a Steam API key. For underlying API documentation and technical guidelines, see the official Steam Web API Documentation.
