Agent Browser

Accelerate development by managing all your MCP server in one place

Installation • Client Integration • API Documentation • Development

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.

Without Agent Browser

With Agent Browser

✓ Add new server in Cursor
✓ Add new server in Windsurf Client
✓ Add new server in Claude Client
✓ Repeat for each additional client
✓ Update all clients when server changes

✓ Add new server once in Agent Browser UI
✓ Update once in Agent Browser when server changes

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.

API Documentation

The Agent Browser exposes a REST API for integration. For details on accessing the API documentation, using Swagger UI, or integrating with tools like Postman, see API.md.

Future Direction

Protocol Support Implementation

We plan to expand Agent Browser to support additional protocols alongside MCP.

Future Tasks

Add A2A protocol support
Add ACP protocol support
Implement protocol auto-detection
