Connect Ezus to Mistral Vibe (ex-Le Chat)

The connector is currently in beta. It is safe to use on your account, and its features will keep evolving. Your feedback directly shapes what comes next.

The Ezus connector for Mistral Vibe lets you query your data, check your files and automate certain operational tasks directly from Mistral Vibe, Mistral AI's AI assistant, without changing the way you work.

Once Ezus is connected, simply ask your question in plain language, for example "Which projects leave next week?". Mistral Vibe looks up the answer in your Ezus account.

💡 The connector is available from the Ezus Premium plan.

What is MCP?

The connector relies on MCP (Model Context Protocol), a standard that lets an AI assistant access software securely. No technical skills are needed, and connecting takes just a few clicks.

By default, Mistral Vibe can only view your Ezus data. To let it create or edit items as well (projects, products, payments…), ask your Ezus contact to enable write access.

1. Before you start

Check these points before you begin:

  • An Ezus Premium plan or higher.
    ​

  • A Mistral account on chat.mistral.ai, with administrator rights. On the Free, Pro and Student plans, the account holder is the administrator by default. On a Team or Enterprise plan, see section 3.
    ​

  • Your Ezus credentials: the email address and password you use to sign in to Ezus.
    ​

  • Your Ezus account's API key, available in Settings > Developers from https://pro.ezus.io/settings. This page is only accessible to administrators: if you are not an administrator, ask one of your Ezus account administrators for the key.

    ⚠️ The API key is private and must remain confidential. Only enter it in the Ezus sign-in window described in step 4 of the section below.

  • The Ezus server address, to copy exactly as is, with no spaces before or after: https://mcp.ezus.ai/mcp

2. Connect Ezus in 4 steps

Go to https://chat.mistral.ai/work:

  1. Open the Connectors page. On chat.mistral.ai, switch to Work mode, then click on Context > Connectors in the left menu.
    ​

  2. Add a custom connector. Click + Add Connector, then open the Custom MCP Connector tab.
    ​

  3. Fill in the connector details.

    • Connector name: Ezus (no spaces or special characters)

    • Server URL: https://mcp.ezus.ai/mcp

    • Description (optional): Access to my Ezus account

    • Authentication: OAuth2.1

    • Click Add connector.
      ​

  4. Connect your Ezus account. An Ezus sign-in window opens:

    • sign in with your usual Ezus credentials;

    • paste your API key into the Ezus API key field. If you are an administrator, a button takes you straight to the settings page where you can copy it;

    • confirm the key, then authorize access.

You are then redirected to Mistral Vibe, and Ezus shows in the My Connectors tab. The API key is only requested once.

💡 If the Ezus sign-in window does not open, make sure your browser is not blocking pop-ups for chat.mistral.ai.

Choose when Mistral Vibe asks for permission

Mistral Vibe sorts Ezus functions into two groups, each with its own default setting:

Function type

Examples

Default setting

Read only

View a project, search for a supplier

Allowed without confirmation (Allow)

Interactive

Create a project, edit a product

Confirmation requested every time (Ask)

You can change this setting function by function:

  1. In Connectors > My Connectors, click the Ezus card.

  2. In Tools, for each function, choose Allow (allow without confirmation) or Ask (ask for confirmation).

⚠️ We recommend keeping confirmation on for interactive functions.

3. Using a Mistral Team or Enterprise plan?

In a Mistral business workspace, only an administrator can add a custom connector. If you don't see the + Add Connector button, this is probably why.

  1. The administrator adds Ezus once for the whole organization, following steps 1 to 3 above with the address https://mcp.ezus.ai/mcp.

  2. Each user then finds Ezus in Connectors and signs in with their own Ezus credentials (step 4 above).

Each person therefore only sees in Mistral Vibe what their Ezus user rights allow them to see. The administrator has no access to other members' Ezus data.

4. Your first questions

Once connected, open a new conversation: conversations that were already open don't always see the new connector.

  1. In the message box toolbar, open the tools menu and check that Ezus is enabled.

  2. Ask a first question from the examples below.

  3. If Mistral Vibe asks you to confirm a creation or an edit, review it, then click Allow.

Replace the items in square brackets with names from your own Ezus account.

Check the connection

  • "Who am I in Ezus?"

  • "List my last ten projects."

  • "Show me the program for the [name of one of your projects] project."

Find something by name

  • "Find the supplier [name of one of your suppliers] and list what it offers."

  • "Which transfers do we have in [city] for under €100?"

Save time every day

  • "Which confirmed trips in October still have unpaid invoices?"

  • "What's missing before I send the quote for the [name of one of your projects] project?"

If Mistral Vibe shows your name or your projects, the connection works!

Frequently asked questions

How long does the connection last?

The session renews automatically for 90 days. After that, Mistral Vibe simply asks you to reconnect.

Why does Mistral Vibe say it can't create or edit anything?

That's the default behavior: the connector is read-only. To let Mistral Vibe create or edit items, ask your Ezus contact to enable write access for your agency.

Can Mistral Vibe delete my data?

No. The connector has no delete function. Anything you want to delete must be deleted directly in Ezus.

What if Mistral Vibe gets something wrong?

Mistral Vibe asks for your approval before any creation or edit, unless you changed this setting. Keep confirmation on for interactive functions, and check the result in Ezus.

What can Mistral Vibe see in my Ezus account?

Mistral Vibe accesses Ezus with your own credentials. It therefore only sees what your Ezus user rights allow you to see.

I can't find the API key.

The Settings > Developers page is reserved for Ezus account administrators. If you are not an administrator, ask one of them for the key.

The message "MCP connection requires additional information or is invalid" appears.

Check that the address you entered is exactly https://mcp.ezus.ai/mcp, with no spaces and ending with /mcp. On a Team or Enterprise plan, also check that you are an administrator (see section 3).

Mistral Vibe doesn't use Ezus in my conversation.

Check that Ezus is enabled in the tools menu, or open a new conversation. If the problem persists, disconnect and reconnect Ezus once.

Can I connect several Ezus accounts?

es. Add one connector per Ezus account, each with its own API key, and give it a name without spaces that identifies the account.

Can I stop at any time?

Yes. You can turn Ezus off in a conversation, or remove it from your connectors. Your Ezus data stays intact.
