Question : How do I use Mailpro in n8n?

1. In your Mailpro account, on the AI Assistants (MCP) page, copy the server address.
2. In your n8n workflow, add an AI Agent node and, in its tools, the MCP Client Tool sub-node.
3. Choose the HTTP Streamable transport and MCP OAuth2 authentication (with automatic registration on), then sign in to Mailpro.
4. In Mailpro, give this agent a daily cap: it works with no one watching.

Tip: run the workflow with approval for a few days first, to see what the agent wants to send before letting it act on its own.
