SSE Transport

Server-Sent Events (SSE) is the legacy HTTP transport for MCP. It works the same as Streamable HTTP but uses a different endpoint.

Configuration

Add this to your AI app's configuration file:

{
  "mcpServers": {
    "macuse": {
      "url": "http://127.0.0.1:35729/sse",
      "transport": "sse"
    }
  }
}

When to Use SSE

Use SSE only if your AI app explicitly requires it — for example, older versions of Claude Desktop or clients that haven't adopted the Streamable HTTP specification.

Authentication and server address configuration work the same as Streamable HTTP.
