Overview

What is SteamStats MCP Server?

The SteamStats MCP Server is a Python-based Model Context Protocol (MCP) server that acts as an intermediary between an MCP client (like Roo) and the Steam Web API, providing structured access to Steam game statistics and user information. It is built with FastAPI and exposes a single /message endpoint that accepts JSON-RPC style tools/call requests. Note: The README explicitly warns that the current implementation is not operational.

How to use SteamStats MCP Server?

Clone the repository, install dependencies using UV, set the required STEAM_API_KEY environment variable, and optionally configure LOG_LEVEL, HOST, and PORT. Run the server with uvicorn main:app --host $HOST --port $PORT --reload. Connect an MCP client by configuring its mcp.json file with the sse type pointing to http://<HOST>:<PORT>/message.

FAQ from SteamStats MCP Server

Is the SteamStats MCP Server currently operational?

No. The README explicitly states: "Current implementation is not operational!"

What are the runtime dependencies for SteamStats MCP Server?

The server requires Python 3.11+, the UV package manager, FastAPI, Pydantic, Uvicorn, and the Requests library. A Steam Web API key (obtainable from the Steam Developer website) is mandatory.

How do I configure the SteamStats MCP Server?

Configure via environment variables: STEAM_API_KEY (required), LOG_LEVEL (optional, defaults to INFO), HOST (optional, defaults to 0.0.0.0), and PORT (optional, defaults to 8000).

What transport protocol does SteamStats MCP Server use for MCP client connections?

The server communicates with MCP clients over HTTP using Server-Sent Events (SSE). The client must configure its mcp.json file with type "sse" and the server's /message URL.

Where does the SteamStats MCP Server data come from?

All data is fetched from the Steam Web API (e.g., ISteamUserStats, ISteamNews, etc.). The server does not store any data locally; it processes API responses and returns them to the client.
