# Authentication

> Understand authentication for UseAgents MCP tool calls, including the current public beta access model.

UseAgents MCP tools are **currently free and do not require authentication** during the public beta. You can connect to the MCP server without an API key.

<Note>
  During the public beta, no API key or authentication header is required. Requests are subject to [rate limits](/api-reference/rate-limit) to ensure fair usage.
</Note>

## Current setup

Add the UseAgents MCP server to your agent's config with just the URL:

```json theme={null}
{
  "mcpServers": {
    "UseAgents": {
      "url": "https://mcp.useagents.site/mcp"
    }
  }
}
```

No `x-api-key` header or `Authorization` header is needed at this time.

## Verify the connection

After saving the config:

1. Restart the MCP-compatible client if needed.
2. Confirm the `UseAgents` server is available in the client.
3. Ask the agent to use `search_tools` with a simple query.
4. Confirm you receive results instead of an error.

## Rate limits

Even though no API key is required, all requests are subject to rate limits. If you exceed the limit, the server returns an error. See [Rate Limits](/api-reference/rate-limit) for details and recommended handling.

## Future authentication

When the public beta ends, authentication via API keys will be introduced. This page will be updated with setup instructions at that time. You can create an account at [useagents.site](https://useagents.site) to be ready.

## Client-specific setup

For step-by-step instructions for your specific client, see the [client connection guides](/mcp/clients/cursor).
