    Any client that supports remote MCP servers over HTTP works with the server URL.

    | Setting | Value                                           |

    | Sign-in | OAuth. The client finds the details on its own. |

    A client that cannot sign in can send an API key instead. [Create a key](https://radarkit.ai/settings/api/keys) and add this header.

    ```text theme={"system"}
    Authorization: Bearer rk_live_YOUR_KEY
    ```
  </Tab>
</Tabs>

## What signing in does

Allow creates a key for that app on your account, named after the app, with the permissions you ticked. It appears on the [keys page](https://radarkit.ai/settings/api/keys) as a connected app. Click Disconnect there to end the connection at any time. Calls made by the app spend API credits from your account like any other call.

## Start using it

Once connected, ask your client questions like:

* "How visible is Acme in AI answers this week, per model?"
* "Which websites do AI answers rely on most for our project this month?"
* "Which competitors get recommended more than us for our pricing prompts?"
* "Show me the answers from the last two weeks that did not mention Acme."
* "What did ChatGPT search for behind the scenes when answering our top prompt?"
* "Export every answer with the full text for the Pricing topic since June as CSV."

More on the [Recipes](/docs/mcp/recipes) page. If a client says it cannot connect, sign out of it and connect again. If that fails, disconnect the app on the keys page and start over.
