# Connect an AI assistant

> Add the Claimr MCP server to Claude, ChatGPT, Claude Code, Cursor, or any other MCP client that supports remote servers with OAuth.

Every MCP client connects to Claimr the same way: you add the server URL, then sign in with your Claimr account when the client asks you to.

```text theme={"dark"}
https://prod.claimr.io/mcp
```

The Claimr MCP server is a remote server over Streamable HTTP with OAuth 2.1 sign-in. You don't need an API token or a client secret. Clients that support dynamic client registration, which includes Claude and ChatGPT, register themselves automatically.

<Note>
  Menu names in AI assistants change often. If a step below doesn't match what you see, look for a setting called **Connectors**, **Apps**, **Integrations**, or **MCP servers**.
</Note>

## Claude (web and desktop)

<Steps>
  <Step title="Open connector settings">
    In Claude, open **Settings** and go to **Connectors**.
  </Step>

  <Step title="Add a custom connector">
    Click **Add custom connector**. Enter `Claimr` as the name and `https://prod.claimr.io/mcp` as the URL, then click **Add**.
  </Step>

  <Step title="Connect">
    Click **Connect** next to the new connector. A Claimr sign-in page opens in your browser.
  </Step>

  <Step title="Sign in and authorize">
    Sign in with your Claimr account and choose what the connection can access. See [Authorize a connection](/mcp/authorize-a-connection).
  </Step>

  <Step title="Use it in a chat">
    Start a new chat and make sure the Claimr connector is turned on in the tools menu. Then ask something like "List my Claimr campaigns".
  </Step>
</Steps>

<Tip>
  On Team and Enterprise plans, an owner may need to add the connector for the organization before members can connect.
</Tip>

## ChatGPT

<Steps>
  <Step title="Open app settings">
    In ChatGPT, open **Settings** and go to **Apps & Connectors**. If your plan requires it, turn on **Developer mode** under **Advanced settings**.
  </Step>

  <Step title="Create the connector">
    Click **Create**. Enter `Claimr` as the name, `https://prod.claimr.io/mcp` as the MCP server URL, and choose **OAuth** as the authentication method.
  </Step>

  <Step title="Sign in and authorize">
    ChatGPT opens the Claimr sign-in page. Sign in and choose what the connection can access. See [Authorize a connection](/mcp/authorize-a-connection).
  </Step>

  <Step title="Use it in a chat">
    In a new chat, add Claimr from the tools menu, then ask something like "Show me the quests in my campaign".
  </Step>
</Steps>

## Claude Code

Add the server from your terminal:

```bash theme={"dark"}
claude mcp add --transport http claimr https://prod.claimr.io/mcp
```

Then start Claude Code, run `/mcp`, select **claimr**, and choose **Authenticate**. Your browser opens the Claimr sign-in page.

## Cursor, VS Code, and other clients

Any client that supports remote MCP servers with OAuth can connect. Add the server to the client's MCP configuration, for example in Cursor's `mcp.json`:

```json theme={"dark"}
{
  "mcpServers": {
    "claimr": {
      "url": "https://prod.claimr.io/mcp"
    }
  }
}
```

The client starts the sign-in flow the first time it calls the server.

<Warning>
  Clients that only support local (stdio) servers, or that expect a static API key, can't connect directly. The Claimr MCP server only accepts OAuth sign-in.
</Warning>

## Check that it works

Ask the assistant:

> List my Claimr organizations and campaigns.

If the assistant lists them, the connection works. If it reports an error, see [Troubleshooting](/mcp/troubleshooting).
