Control Discord bot with natural language via MCP server
What it is- I wanted to create a simple, easy-to-use, MCP server for your Discord bot(s).
How to set up- Literally all you do is select your bot auth (or crease a new Discord Bot auth if you havn't entered your key in n8n before) and that's IT!
How to use it- You can now ask your bot to do things via any MCP client, including from within N8N workflows!
Note: If you need an example, you can check out my simple quickstart Discord MCP Server that uses 4o to send messages to channels on your server and users who are members of the server the bot is in.

Control Discord Bot with Natural Language via MCP Server
This n8n workflow demonstrates how to integrate with an MCP (Model Context Protocol) Server to receive natural language commands, likely intended to control a Discord bot or similar application. It acts as a listener for incoming requests from an MCP Server.
What it does
- Listens for MCP Server Requests: The workflow is triggered by incoming requests from an MCP Server, indicating that a natural language command or instruction has been received.
Prerequisites/Requirements
- n8n Instance: A running n8n instance.
- MCP Server: An MCP Server configured to send requests to this n8n workflow. This implies a separate setup for the MCP Server itself, which would handle the natural language processing and then forward relevant information to n8n.
Setup/Usage
- Import the workflow: Import the provided JSON into your n8n instance.
- Configure the MCP Server Trigger:
- The "MCP Server Trigger" node is pre-configured to listen for incoming requests. You may need to ensure your n8n instance is accessible by your MCP Server and that the webhook URL generated by n8n for this trigger is correctly configured in your MCP Server.
- No specific credentials are required within this n8n workflow itself, as it acts as a passive listener for the MCP Server.
- Extend the workflow: This workflow currently only triggers. To make it functional for controlling a Discord bot, you would need to add subsequent nodes to:
- Parse the data received from the MCP Server trigger.
- Use a Discord node (or another relevant service node) to perform actions based on the parsed natural language command.
- Handle error cases or provide feedback.
