Steam (read-only) MCP Server

A read-only Model Context Protocol server for the public Steam Web API and storefront - 37 tools, 5 prompts, and 2 resources that let any MCP client (Claude Desktop, Claude Code, Cursor, …) answer questions about Steam: your friends, games, playtime, and achievements, plus account-independent things like sales, reviews, live player counts, Steam Deck compatibility, discovery, recommendations, and co-op planning.

People who work with steam, app and player and want it reachable from Claude, Cursor, VS Code, or another MCP client. The project is written in Python.

pypi package steam-mcp - check the name against the project README before installing (PyPI has no namespace ownership)

registry namespace io.github.Sarg338 is GitHub-verified and matches the repo owner
