Deploy and Host HopMCPStack For Unreal Engine on Railway

HopMCPStack for Unreal Engine is a lightweight MCP schema server that publishes Unreal Engine 5 editor tool definitions for AI clients. It allows assistants to discover available tools, parameters, and capabilities while delegating real execution to the local Unreal Editor.

About Hosting HopMCPStack For Unreal Engine

Hosting HopMCPStack involves deploying a containerized Python FastMCP server that exposes Unreal Engine tool schemas over HTTP. The service is stateless, loading bundled JSON tool definitions at startup and serving them to MCP-compatible clients. Railway simplifies deployment by automatically building the Docker image, provisioning networking, managing environment variables, and generating a secure public HTTPS endpoint. No database or persistent storage is required, making scaling straightforward. Updates are handled by pushing repository changes, which trigger automatic redeployment. This setup enables centralized schema discovery for teams, CI pipelines, and AI-assisted Unreal Engine workflows without requiring Unreal Editor to run continuously.

Common Use Cases

• Enable AI assistants to accurately discover Unreal Engine editor tools and parameters.
• Provide a centralized /tools.json endpoint shared across multiple development machines or teams.
• Support CI, automation, and headless build workflows that require MCP schema availability.
