## Overview

Agent Browser eliminates the need to configure each MCP server in every client. Connect your clients once to Agent Browser, and it will manage all your Server-Sent Events (SSE) MCP servers for you.

## Client Integration

### Cursor

After installing and running Agent Browser, Cursor will automatically detect and connect to it. No additional configuration needed.

### Other MCP Clients

Add Agent Browser as an SSE endpoint in your MCP client configuration:

```json
{
  "Agent Browser": {
    "url": "http://localhost:8087/sse"
  }
}
```

Once your client is connected to Agent Browser, you can add or remove MCP servers without touching your client configurations.
