Usage

Tools

This MCP service provides the get_steam_review tool. Pass a Steam app id and the tool reads:

• IUserReviewsService/GetAppReviews
• IStoreBrowseService/GetItems

store.steampowered.com/appreviews was disabled on 2026-10-22. Parameters use the old string names (all, recent, steam) and the server maps them into input_json.

The tool returns text JSON and the same object as structuredContent:

1. game_reviews:

   • success: true when Steam returned a response object
   • review_score: Review score, or null when that page has no score
   • review_score_desc: Review score description
   • total_positive: Total positive reviews
   • total_negative: Total negative reviews
   • total_reviews: Positive plus negative totals
   • total_matching: Reviews matching the filter
   • day_range_used: Day range the Helpful filter actually searched
   • cursor: Pass this back to fetch the next page
   • reviews: Cleaned review text for this page

2. game_info:

   • name: Store name
   • detailed_description: Store description with BBCode removed

An empty Steam response means no matching reviews. Aggregates are null and reviews is empty. Set STEAM_WEB_API_KEY only when you need the higher rate limit. The public methods work without it.

Code mode

The server stays compatible with Cloudflare's single-tool code mode as an upstream SDK v1 server. get_steam_review publishes an output schema, read-only annotations, and structuredContent. A host can wrap this server with codeMcpServer(). This package does not replace its tools with a code tool, because that wrapper is host-side and current code mode still serves the legacy SDK v1 handler.
