# Sigma

Add SpecStream to Sigma as an MCP connector. Sigma agents ask for live web data in plain words, show the most a request can cost, and bring back the records.

[SpecStream for SigmaData & warehouses](https://specstream.ai/integrations/sigma.md)

## What you need

-   A Sigma Admin account, or an account type with the **Manage MCP connectors** permission.
-   For whoever builds the agent: an account type with **Use MCP connectors**, **Manage agents**, and **Create, edit, and publish workbooks**, **Can use** access to the connector, and **Can edit** access to the workbook.
-   A SpecStream account. New accounts get $10 of work free, with no card.

    ## 1. Add the connector

    Go to **Administration**, then **MCP connectors**, and click **Add MCP connector**.

    Enter `SpecStream` as the **Name**. In **Description**, say what the connector does, because agents read it to decide when the tool applies. Enter `https://api.specstream.ai/mcp` as the **MCP server URL**. Sigma validates the URL on its own.

    In **Instructions**, you can tell the agent which tools to use or how to format answers, for example to show the source URL beside each value.

    Description

    ```text
    Finds companies, local businesses, grants, tenders, clinical trials, papers and datasets on the live web. Every value comes back with its source URL and read time.
    ```

    ## 2. Authorize and save

    Under **Authentication credential**, choose **OAuth with Dynamic Client Registration** and click **Authorize**. Sigma adds an OAuth API credential for you. Click **Test** if you want to check the definition and the authentication and review the available tools, then click **Save**.

    ## 3. Grant access

    Open the connector and, in **Connector access**, click **Grant access**. Search for users or teams and choose **Can use** to let them add the connector to an agent, or **Can edit** to let them manage it. Add **All members of your Sigma organization** to give everyone use access. Add a message for the email notification, or clear the checkbox to skip the email, then click **Save**.

    People find the connectors available to them under **Profile**, then **Integrations**, then **Available MCP connectors**.

    ## 4. Add it to an agent

    When you create or edit an agent, click **+** next to **Tools** and select **MCP connector**. Search for SpecStream and select it. Add instructions that tell the agent when to use it, then click **Save** to go back to editing the workbook.

5.  5

    ## 5. Ask the agent

    Describe what you need and where:

    `SaaS companies in London that use HubSpot, with their website`

    SpecStream reads the request back so you can see how it understood it, then gives the most the request can cost. Approve that amount and the run starts. The results come back with the source URL and read time of each value.

## Who can use it

Sigma agents can only use tools the person chatting has access to, so **Can use** access to the connector decides who reaches SpecStream.

## An API key instead of OAuth

For a credential Sigma doesn't create for you, go to **Administration**, then **API connectors**, open the **Credentials** tab, and click **Create credential**. This takes the **Manage API connectors** permission. Enter a name and `api.specstream.ai` as the authorized domain, choose **Bearer token**, enter a SpecStream API key as the **Token**, and click **Save**. Then choose it under **Authentication credential** on the connector. Create the key in your workspace under **Agents & API** and give it only the projects, operations and spending limit the task needs.

## If the sign in runs out

If a person's OAuth token for SpecStream expires during a chat, Sigma asks them to authorize again.

## Cost

Connecting SpecStream to Sigma costs nothing on SpecStream's side. SpecStream bills your balance for the records that match a request, never above the maximum you approved, and a request that finds nothing is free. [Balance, quotes, and billing](https://specstream.ai/docs/billing.md) has the rates.
