Make your account behave like a bot and mirror messages from a server to another.
I take no responsibility for using this bot against Discord TOS.

• Send messages disguised as the original sender.
• Replace mentions of mirrored messages to match a valid mention on your server.
• Allow customization of status (online, invisible, idle, busy).
• Allow mirroring one or more messages to one or more webhooks.
• Optimized and lightweight.

Original message (from server A):

Mirrored message (to server B):

• NodeJS (v16.17.0 or higher)

1. Install the requirements.
2. Enter the project folder and:
3. Run: npm install to install the dependencies.
4. Configure config.json (see below).
5. Run: node discordMirror.js.
6. You are now mirroring! >:)

token: is the token of the discord account that will mirror. Learn how to find your token here.
(Note that the token must be that of a personal discord account and not a bot).

status: is the status of the account that will mirror: online, offline, idle or dnd. (Note that you must not be logged in the account while the bot starts for this option to take place).

mirrors:

• channel_ids: list of channel IDs where when a message is sent, it is mirrored. (you can get the ID of a channel by enabling the Developer mode in your discord settings and Right-Click -> Copy ID on a channel).
• webhooks_urls: list of webhooks URLs where the mirrored message is sent. (you can create a webhook for a channel in your discord server with Right-Click -> Integrations -> Create webhook).

mentions:

• "INSERT_SERVER_ID_HERE": ID of the server where the mention must be replaced.
  • original: ID of the role/channel in the original server.
  • replaced: ID of the role/channel in the destination server.

Explaination of the configuration above:

• When the bot starts it will set its status to offline (invisible).
• When a message is sent in the channel with ID: 937789483387898821, it will be mirrored to the channel having the webhook: https://discord.com/api/webhooks/1262444920615UrWvVK6yEDjPYw3u3xEe.
• If the message is mirrored in the server with ID: 238572387938571039 and contains a mention to a role/channel with ID: 712972387912041481, the mention will be replaced with a mention of the role/channel with ID: 533971387929810147.
