Simpler, streaming-by-default connections to external MCP servers

When a URL is provided, MCPTools now default to StreamableHttp transport. This makes it easier to connect to external MCP servers and improves streaming behavior out of the box, reducing configuration overhead.

Details

Better defaults for modern streaming workflows and real-time interactions
Fewer setup steps when integrating with third-party MCP servers
To retain previous behavior, explicitly set your preferred transport

Who this is for: Teams integrating MCP servers that want faster setup and more reliable streaming by default.
