Koskamo

steamworks-mcp

An open-source MCP server that assists indie developers in releasing games on Steam. It scans Unity, Godot, or Unreal projects to extract metadata, drafts store page content, checks compliance with Valve's rules, and prepares Steamworks data for manual approval. It supports market analysis and code integration checks without publishing automatically.
