[Feature Request]: Streamable-http for workflows as mcp tools

[rangan2510]

Feature Description

The tutorial listed here (https://docs.llamaindex.ai/en/stable/examples/tools/mcp/#converting-a-workflow-to-an-mcp-app) speaks solely about SSE. However SSE is deprecated in newer versions of MCP implementation and is replaced with streamable http.

The tutorials need to be updated. Moreover, since workflows can also have calls to LLMs inside them, it would help to have an example of an mcp tool which streams the response.

Reason

MCP has deprecated SSEs in favor of streamable HTTP.

Value of Feature

Keep the framework compatible with the newest standard of MCP.

Hey @rangan2510: if you already have a tutorial or example for this, feel free to open a PR, otherwise I can look into it later today :))

@AstraBert I'll have a look at this over the weekend.
The idea is that I may have a streaming agent working as a tool. I would like to see how I can stream the tool output to the mcp client.
