Agent Browser

---

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.

Usage

Access the web UI at http://localhost:8080/ui/ to:

• View connection status of your MCP servers
• Add new MCP server connections
• Remove existing connections
• Monitor connection health in real-time

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:

{
  "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.
