How do I get my master public key from a wallet?

If a HD wallet only gives me the 12 word mnemonic, how can one get the master public key?

What wallet software are you using? You've tagged this [tag:bitcoin-core] but AFAIK it doesn't use mnemonics. Some wallet software will show you the master public key, though it might be buried in a menu somewhere. You can also recover it from the mnemonic with third-party tools like coinomi, though this requires you to trust that the software is not malicious (it could steal your coins if it were).

when you have your 12 words, and you are tech-savvy (the logic behind BIP32 or 39), then you can also try to download this website locally, and go from there: https://iancoleman.io/bip39/#english - but why would you want your master public key? Not the master priv key?

@pebwindkraft if you have the master public key, you can give it to a business for example to send payments spreaded out to different addresses, that's one use case. Thanks for the knowledge!Kyle Graham 2018-01-16T20:56:30.863

yup, I have seen your other posts, and now I know, there's more to it. A newbie user would ask for lost keys ... :-)pebwindkraft 2018-01-17T07:59:55.293
