# Install Lightsage MCP in Claude

> Connect Claude hosted connector surfaces to Lightsage MCP with OAuth.

Use this path for Claude web (claude.ai), Claude Desktop custom connectors, Claude mobile, and other hosted Claude connector surfaces.

The hosted Lightsage MCP endpoint supports OAuth, so Claude connects directly. You sign in with your Lightsage account and choose which organization the connection can access — no API key, and nothing to paste into a config file.

<Steps>
  <Step title="Add a custom connector">
    1. Go to [Add Custom Connector](https://claude.ai/new?modal=add-custom-connector#settings/customize-connectors).

    2. Set **Name** to `Lightsage`.

    3. Set **Remote MCP server URL** to:

       ```text theme={null}
       https://mcp.lightsage.com/mcp
       ```

    4. Leave **OAuth Client ID** and **OAuth Client Secret** blank. Claude registers itself with Lightsage automatically.

    5. Click **Add**.
  </Step>

  <Step title="Sign in and authorize">
    Claude opens a Lightsage sign-in window:

    1. Sign in with your Lightsage account (the same login you use for the dashboard).
    2. Choose the organization this connection should access.
    3. Review the requested permissions and approve.

    Claude receives an access token scoped to the organization you selected. The connection can only act on that organization.
  </Step>

  <Step title="Test the connection">
    In a new chat, confirm the connector is enabled, then run a read-only prompt:

    ```text theme={null}
    Use the Lightsage MCP server to check my Lightsage auth status.
    ```
  </Step>
</Steps>
