Mistral Le Chat supports custom MCP connectors.

Prerequisites

Connect

1

Add the Langmail connector

In Le Chat, open the connectors settings (Intelligence → Connectors), choose Add connector, and fill in:
  • Name: Langmail
  • Server URL: https://mcp.langmail.me/mcp
2

Authorize access

Le Chat starts the authorization flow: sign in to your Langmail account and approve the consent screen.
3

Enable it in a chat

In a conversation, enable Langmail in the tools menu. The tools now appear in the agent’s tool list.

Test it

Ask Le Chat:
Prompt
It calls search_emails with { "mailbox": "Inbox", "limit": 5 } and answers from the result.

Ending access

Remove the connector from the connectors settings. Removing it discards its tokens; without the refresh token, access lapses when the current access token expires.

Next steps

Search and triage email

Real prompts and the tool calls they produce.
