Connect Vibe (Le Chat)
Mistral's Vibe (Le Chat) calls these connectors, and you can add your own on every plan, including Free. One thing to know first: only a workspace admin can add one. On a Free, Pro or Student account that is you. In a team workspace, ask whoever runs it.
Add the connector
- Open Connectors in Vibe (Le Chat) and select + Add Connector.
- Switch to the Custom MCP Connector tab.
- As the connector name, type
hiasynth. Vibe (Le Chat) does not allow spaces or special characters in the name. - Paste this as the server URL, add a description if you like, and click Connect.

Vibe (Le Chat) works out by itself how Hiasynth signs people in, so there is nothing to choose. A Hiasynth page opens. Sign in with Google, GitHub or Discord (new here? that just made your account), read what Vibe (Le Chat) is asking for, and click Approve and subscribe, or Approve if you already have a subscription.
The card tells you which app is asking and where you'll be sent back
Ask
Start a new chat and type:
Who lives within three kilometres of the Vieux-Port in Marseille, and what is the area like by day?
Vibe (Le Chat) reaches for Hiasynth, runs the profile, and answers from the numbers.
If Vibe (Le Chat) answers from memory instead, check that the Hiasynth connector is switched on for the conversation, or name us in the question: "use Hiasynth to...". Vibe (Le Chat) uses Hiasynth's tools but does not yet read the two reference documents our server offers to assistants, so it helps to be a little more explicit about the place and the audience than you would be in Claude.
Next, set it up for your job: a few lines of instructions turn your assistant into an expansion manager, an audience strategist or a location scout that works the same way every time. Stuck? Troubleshooting has the fix.
