# 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.

## What you need

-   A Mistral account whose user is an administrator. On Free, Pro and Student plans the account owner is the administrator by default.
-   A SpecStream account. New accounts start with $10 of credit, no card. [Create one](https://specstream.ai/signup?utm_source=le-chat).

1.  1

    ## 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.  2

    ## 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

    ```text
    https://api.specstream.ai/mcp
    ```

3.  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.  4

    ## 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_price` and `get_research`, which only read. Leave `start_research` on manual approval: it is the one call that spends.

5.  5

    ## 5. Ask for a report

    Start a task in Work and name the Connector in the request:

    In Work

    ```text
    Use SpecStream to research: which EU countries require e-invoicing for B2B sales in 2026, and from what date? Show me the price of each depth first, then start a standard report.
    ```

## 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.
