realm-engine-client vs fastapi_mcp
realm-engine-client: Realm Engine is a free, open-source hacking platform for Realm of the Mad God (RotMG / Exalt), offering features like autonexus, autododge, and autoloot. It includes an Electron client, an IL2CPP DLL injector, and a TypeScript SDK, allowing users to build and customize their own game modifications without subscriptions.; fastapi_mcp: FastAPI-MCP allows you to expose your existing FastAPI endpoints as Model Context Protocol (MCP) tools. It offers native integration with FastAPI, including built-in authentication using existing dependencies, and preserves schemas and documentation.

Enhance RotMG gameplay with automated combat, movement, and looting.

When to choose:
- You already have a FastAPI application and want to expose its endpoints as MCP tools while reusing your existing FastAPI authentication dependencies and Swagger schemas.
- You want to mount the MCP server directly onto your ASGI app or deploy it separately under an MIT license.
When to skip:
- You are building a standalone MCP server from scratch rather than wrapping a FastAPI app; use FastMCP or the official MCP Python SDK.
- You need an actively updated repository (last push was November 2025).
