About Agent Browser
Agent Browser is a tool that manages several SSE-based MCP servers in one place. Clients connect to it once, so MCP servers do not have to be configured in each client separately. It suits users who work with multiple MCP clients.
Key features
- 01Single SSE endpoint for clients
- 02Web UI for connection status
- 03Real-time connection health monitoring
- 04REST API for integration
Use cases
- 01Share one set of MCP servers across Cursor, Windsurf and Claude
- 02Update server changes in one place instead of every client
MCP support
Agent Browser acts as an MCP intermediary. Clients connect to its SSE endpoint, and it manages the connections to the underlying SSE MCP servers.
Configuration
Local server config is the same for every client. Copy it into your client’s MCP config file.
We haven’t collected a package or remote endpoint for this server. Follow the instructions in the project README.
Tools
Local servers expose tools only once running on your machine, and the maintainer has not provided a tool list.

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.

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

New to MCP?
From what the protocol is to installing your first server, these answers cover most first questions.
An open protocol that defines how AI applications connect to external tools and data in a uniform way. Clients talk to the model; MCP servers provide tools, resources and prompt templates. They exchange standard messages, so one server can be reused by many clients.
