This gets all of the servers that your discord bot is currently in. If you have a bot in more than one server, you will need to let it know or at least hint at which server it is, or it may get stuck. If you specify a channel through your natural language request, then the model may keep trying to get servers' channels via the get channel node or it may give up before getting to the right one).
Note: This is a custom API call using the same Discord bot auth, not a built-in \"Discord tool\" - I encourage you to go well beyond the 15 included tools that n8n provides for you. It is *easy* to do, and there are, literally, no limits to what you can do with n8n!"

Programmatic role addition and removal are just two examples of the many, many tools/API calls that you can make to Discord.
You could monitor for spam, mod abuse, or anything else you wanted and respond automatically by removing perms until you can check it out.
You can create amazing workflows that include discord webhooks, your existing other workflows, or anything else you can imagine and have it running on your bot in minutes via a MCP client node in a new or existing workflow!"
