Yes! A bot does nothing special at all (the only difference is that they can get the Bot permission to hide their changes from Special:RecentChanges by default). Bots use the API instead of the GUI.

If you're looking to set up a bot, you can use AutoWikiBrowser, if you need help with that let me know! It's a simple program (windows-only unfortunately) that can easily do search-and-replace. I have a bot if you want me to do tasks.
