# Install Lightsage MCP in Perplexity

> Connect Perplexity custom remote MCP connectors to Lightsage MCP.

Use this path if your Perplexity plan includes custom remote MCP connectors.

<Steps>
  <Step title="Get your Lightsage API key">
    Open the [Lightsage dashboard](https://app.lightsage.com/settings/api) and copy your API key.

    Do not put your API key in shared connector docs, screenshots, issue reports, or public repositories.
  </Step>

  <Step title="Add a Perplexity connector">
    Add Lightsage as a custom remote MCP connector:

    1. Open Perplexity's connector settings.
    2. Add a custom remote MCP connector.
    3. Set the server URL to `https://mcp.lightsage.com/mcp`.
  </Step>

  <Step title="Configure API-key auth">
    Choose API key authentication. Set the header name to `X-Lightsage-Api-Key` and the value to your Lightsage API key.

    If the connector UI only supports OAuth or open authentication in your workspace, it cannot connect directly to the hosted Lightsage MCP endpoint today. Use a private server-side wrapper that injects the Lightsage API key for testing.

    Then run a read-only prompt:

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