i've done all the readme says, this happens
i'm using only a claude api key

This is most likely because you are using a version that is not supported by the minecraft-data module. 1.20.1 should be supported but I think 1.20.4 is not. If you are already using an 1.20.1 try doing npm update to update installed modules.

1.20.4 should also be supported, but I don't think any higher than that is.
