# Connect while to Mistral Vibe, formerly Le Chat, over MCP

Mistral's Le Chat is now called Vibe. Connected to while with an MCP connector, it deploys your apps, with their database, and asks for your approval on what matters.

## Prerequisites

- A Mistral Vibe account, formerly Le Chat (source 1).
- The right to add a connector: on the Free, Pro and Student plans, the account holder has it by default (source 2).

## Step 1: Add while as a connector

Open the Connectors page, click "+ Add Connector", then the Custom MCP Connector tab (source 2). Name it while, with no spaces, and paste the address of while's MCP server:

```text titre="MCP server address"
https://app.while.sh/mcp
```

Click Connect: Vibe detects while's OAuth authentication on its own (source 2).

## Step 2: Authorize it in your browser

A while page opens. Choose "A new app", then click Authorize.

## What your agent does

Vibe then sees while's tools: deploy, create a database, read the logs, query the database, open a preview, roll back. In the conversation, it sends your app's files to while in its tool calls, then deploys it.

## Deploy what Vibe just wrote

> You, to your agent: Deploy this app with while.

Vibe writes while.yaml, sends the code, and gives you your app's address, over HTTPS.

## Query your database

> You, to your agent: How many sign-ups this week?

Vibe reads your database in SQL over MCP, with your permissions on the data, and can't write to it.

## Go back to the previous version

> You, to your agent: Go back to the previous version.

In the 30 minutes after a deployment, the previous version comes back in a second. After that, it takes a few seconds.

## Questions

### Are Le Chat and Vibe the same product?

Yes: Le Chat has been called Vibe since May 28, 2026, and your conversations, settings and plan carried over (source 1).

### Does my agent see my keys?

No: your keys stay in while, and calls to an external API go through while, which adds the key.

### What can Vibe do without me?

It can deploy, and read the logs and the database. Sensitive actions, like deleting a production database, wait for your approval.
