Steam MCP

What it does

Steam MCP connects AI agents to the Steam Web API, allowing them to retrieve real-time data about Steam user profiles, game libraries, global achievements, and store information. It enables users to ask natural-language questions about their gaming habits, track backlog progress, and research game trends.
