## What it does

The server gives an agent access to Steam data through Trends API. Ask for a game's monthly history, compare growth across periods, or retrieve the current most-played list. Game lookup uses its display name rather than an AppID.

Historical values are an index from 0 to 100 relative to that title, not raw player counts. The series is monthly, so it does not show day-by-day CCU changes. In Claude Code, add the server with `claude mcp add --transport http steam-trends-api https://steam.api.trendsapi.ai/mcp`.
