Le Chat research reports
Add SpecStream to Mistral Vibe, formerly Le Chat, as a custom MCP Connector, and a task in Work can order a research report: a written answer from the live web with a numbered citation after each cited sentence. An administrator adds it once, with one address.

1. Open Connectors and add a custom Connector
In Vibe, open the Connectors page, click + Add Connector and switch to the Custom MCP Connector tab. Adding a Connector is an administrator-only feature.

2. Fill in the three fields
Connector name takes no spaces or special characters, so write
SpecStream. Paste the address below as Server URL. Description is optional: a line such as "Research reports, web search and page reading from the live web" tells your team what the Connector is for.Server URL - 3
3. Click Connect and sign in
Click Connect. Mistral detects the server's authentication method from the address. SpecStream answers with OAuth 2.1 and dynamic client registration, so there is no client ID or key to paste: sign in to SpecStream and approve the access.
Each person signs in with their own SpecStream account, so a report is paid from that person's balance and held to their spending limits.

4. Choose which functions run without asking
Go to Connectors, select the My Connectors tab, click the SpecStream card and open the Functions tab. Toggle Always allow for
research_priceandget_research, which only read. Leavestart_researchon manual approval: it is the one call that spends. - 5
5. Ask for a report
Start a task in Work and name the Connector in the request:
In Work
What happens when you ask
Work calls research_price and shows the price of each depth. When you approve one, it calls start_research with that price as the most the report may cost, then reads get_research until the report is completed.
The report comes back as Markdown with a [1] marker after each cited sentence. Each citation gives the page's address and title, the time SpecStream read it and the passage behind the sentence. Ask Work to put the report in Canvas to edit it.
Price and time by depth
The price is taken from the balance once, when the report is delivered. A cancelled report is not charged. The $10 of credit on a new account covers 100 quick reports or 33 standard ones.
| Depth | Price a report | Time |
|---|---|---|
| quick | $0.10 | About one minute |
| standard | $0.30 | About four minutes |
| deep | $1.00 | About five minutes |
Deep Research in Vibe and a SpecStream report
Mistral's docs call Deep Research a legacy Chat feature and say the Chat tab is being removed progressively. In that Research mode, Libraries, Connectors and Agents are disabled, so a SpecStream report cannot start there. Start it from a task in Work, where Connectors run.
Mistral points to the Deep Research Skill in Work as the replacement, and that Skill works with Connectors. A SpecStream report is a second way to get a cited report in the same place: it has a fixed price, three depths, and a citation that holds the passage behind each sentence.
The other functions the Connector adds
The same Connector gives Work SpecStream's other tools, on the same account:
search_web: one search of the live web, $5 per 1,000 searches of up to 10 results.read_pages: the text of pages you name, $0.80 per 1,000 pages. A page with no text is not charged.compile: a list or table from the live web, priced before it runs.
If Connect fails
Mistral shows "MCP connection requires additional information or is invalid" when it cannot reach or read a server. Check that the Server URL is exactly https://api.specstream.ai/mcp, with no path after /mcp. Custom MCP Connectors do not yet support dynamic tool discovery, resources or automatic prompt templates. SpecStream's research functions need none of them.

Disconnect
Remove the SpecStream Connector on the Connectors page. To end its access on the SpecStream side, open Agents & API in your workspace, choose OAuth applications, and revoke it. Your reports stay in your SpecStream account.
