If it’s a single-use bot then do Special:Mypage/common.js from the bot account. If it’s a multi-wiki not then do w:Special:Mypage/global.js from the bot account, to have to affect all Wikis. You should always ensure that you have approval from local administrators before using a bot however (& flag the bot too), since operating a bot without clearance is likely to get you blocked.
