Send a fax from Mistral Le Chat
Updated
Mistral's Le Chat can send and read faxes for you through the Fax for Agents connector. You describe the fax in plain words. Le Chat prepares the page, gets a quote and sends it. By default it sends inside the limits your organization set, with no approval per fax. This guide was recorded in Sandbox mode, so nothing reached a real fax line.
Before you start
- A Fax for Agents account. The dashboard is at app.faxforagents.com.
- The Fax for Agents (OAuth) connector in your Le Chat workspace. Open Connectors, add the connector with the MCP address mcp.faxforagents.com and sign in. Keep the box "Let this app send faxes within your limits without asking" ticked on the consent page.
- The Connected apps switch in Settings is on by default. The default limits are $5.00 per fax and 20 faxes a day.
1.Open the connector
Open Connectors in Le Chat and select Fax for Agents (OAuth). The connection reads Valid.
2.Check the tools
The Tools section lists every tool in two groups. Interactive tools are set to Ask, so Le Chat confirms before one of them runs. Read-only tools are set to Allow.
3.Start a chat
Select Try now at the top of the connector page. A new chat opens with the connector as a chip in the composer.
4.Choose Always allow
Type what the fax should say and where it goes, and say send. Before the first tool runs, Le Chat shows a card that names the connector and the tool.
5.Describe and send
Le Chat prepares a one page document, quotes it and sends it in the same turn. The answer names the number, the status and the carrier reference.
6.Check the evidence
Ask for the delivery evidence when you want the full record.
7.Read the inbox
Received faxes work the same way. Ask for your inbox.
What the limits mean
Open Settings in the dashboard. The Connected apps card holds the switch "Let connected apps send without asking". Under it are two fields, "Amount per fax, at most" ($5.00) and "Faxes per day" (20). Apps like Le Chat send inside these limits with no approval per fax. Turn the switch off and every send waits for a person. Finer limits, such as destinations or one app only, live under Policies. See the guide Your assistant sends within limits by default.
Approve every fax instead
- In Settings, turn off "Let connected apps send without asking" and choose Save.
- Ask Le Chat to quote the fax. The quote says a person must approve it.
- Say "Ask a person to approve it." A person approves in the dashboard, then you tell Le Chat to send.
The full routine is in Approve every fax from ChatGPT. It works the same way in Le Chat.
Troubleshooting
- Le Chat answers "This model is at full capacity right now" with a Retry button. That is Le Chat's own capacity notice on the Free plan. Select Retry and the turn continues where it stopped.
- The confirmation card appears again for the next tool. Le Chat asks once per tool, even after Always allow for this chat. Choose it again. To stop the cards for a group of tools, set the group to Allow under Tools on the connector page.
- The quote says a person must approve the send although you expect a plain send. An owner turned the Connected apps switch off, or the fax is above a limit. Check Settings, Connected apps for your environment.
- The connection reads Invalid or Reconnect instead of Valid. Open the connector page and select Connect another account. The consent page opens in a new window, and the Sandbox or Live choice is made there.
