Documentation

Cross-Fleet Pipeline

Steam-MCP is the publishing backend for godot-mcp — the fleet's Godot game builder. Export Windows builds from Godot, stage them in the fleet exchange, and upload via SteamPipe:

godot-mcp (export + stage) → steam-mcp (VDF + steamcmd upload)

See godot-mcp Ship to Steam and STEAM_PUBLISHING.md in mcp-central-docs.

Requirements

• Python 3.12+ and uv

• Steam Web API key for profile/library/workshop tools

• SteamCMD for publishing operations (optional)
