Oops! Something went wrong! :(

ESLint: 9.39.3

ESLint couldn't find an eslint.config.(js|mjs|cjs) file.

From ESLint v9.0.0, the default configuration file is now eslint.config.js.

figured out the problem... i notice the ESLINTRC files are not included in the v0.5.17 release that I downloaded under "releases"

Installation instructions worked fine when I cloned the repo instead.

I did not know what "cargo" was... but in order to get wasm-pack installed I first needed to get rust installed
https://rust-lang.org/tools/install/

This might seem like an obvious pre-req to rust developers but I have never used rust.

After installing rust... I was able to use "Cargo" to install wasm-pack and build wasm.

This is the 4th project I'm playing with that calls itself "Unreal MCP".
I would suggest a different name to avoid confusion :P

Thanks a ton for figuring this out and dropping that comment! 😄

😅Yeah, the Cargo/WASM stuff is totally optional — you don’t need Rust or anything for the MCP server to work. It just skips that part automatically.

I saw the ESLint issue you mentioned too, so I’m removing it from the published package right now so it won’t run those prebuild checks on install anymore.

I’m fixing it up and pushing 0.5.18 in a few minutes. Once it’s live just run npm install unreal-engine-mcp-server@latest and it should install clean.

Really appreciate you testing it and the feedback — you’re helping a lot!

And yep, I’d love your name suggestions! Throw whatever ideas you have at me. Just don’t suggest any name that contains “unreal”. 🤣

What does the WASM part even do? Is it even necessary? If it's not needed maybe it can be removed to reduce bloat?

You're Welcome! I'll keep helping out where I can. Just happy to find an Unreal MCP project that is being actively worked on! :)

You could just throw the idea to an LLM.

Here's some random ones off the top of my head... "UE MCP", "Dragon MCP", "MCP4Real" etc.

Yh I but like simple Unreal_mcp name while MCP4Real is just too real to be real. And wasm is optional but it saved few seconds on some tools call while it is not widely wired yet so you won't notice anything for now.

It;'s not that it's a bad name.. its that every other project on github is also called "Unreal MCP".
