Chapter 5.3.3 -- Streamable HTTP Transport

Companion code for Generative AI in .NET, Chapter 5 section 5.3.3 ("Streamable HTTP: The Modern HTTP Transport").

The recommended HTTP transport for new MCP servers. A single /mcp endpoint accepts POST with Accept: application/json, text/event-stream -- the server decides per request whether to return a single JSON response or stream events.

Run it

dotnet run --project samples/ch05-mcp/05.3.3-streamable-http

The server listens on http://localhost:5183. Pair with StreamableHttpClientTransport from any MCP client sample.
