Le Chat has been called Vibe since May 2026: same assistant, same address.
- In your Mailpro account, on the AI Assistants (MCP) page, copy the server address.
- In Vibe, open Connectors, click + Add Connector, then the Custom MCP Connector tab.
- Enter a name with no spaces (Mailpro), paste the address, then sign in to Mailpro and accept the permissions.
- In Vibe, choose which tools stay under approval; in Mailpro, set the sending rules.
Adding a custom connector is limited to the admin; on individual plans, that is the account holder. The full guide: Mistral and Mailpro.
