It had absolutely no trouble understanding what it is, and deobfuscated it perfectly in on it's first attempt. It's not the cleverest obfuscation (https://codebeautify.org/javascript-obfuscator) but I'm still moderately impressed.
It’s terrible at confirming prior work, if I label something incorrectly it will use that as if it was gospel.
Having a very clean function with lots of comments and well named functions with a lot of detail that does something completely different will trip it up very easily.
That's funny, sounds like you'd get better results by obfuscating then. (Relative to partially deobfuscated code that might have incorrect names.)
I have a silly side project that ended up involving the decompilation of a toaster ovens firmware, the firmware of the programmer for said toaster ovens MCU, and the host side programming software. They were able to rip through them without a problem, didn't even have ghidra setup, they just made their own tools in python.
But it need not have to be, WebMCP can (should?) respect website's choice;
