MCP 2026-07-28 protocol demo

A companion to ../transport-http, showing what changed in the 2026-07-28 MCP specification revision — the largest rewrite of the protocol since it launched. Uses the beta Python SDK (mcp==2.0.0b1).

Card

Demonstrates

1. server/discover

Replaces the initialize/notifications/initialized handshake

2. Stateless add call

No Mcp-Session-Id anywhere; required MCP-Protocol-Version/Mcp-Method/Mcp-Name headers; resultType: "complete"

3. book_table (MRTR)

Multi Round-Trip Requests: resultType: "input_required" + retry with inputResponses/requestState, replacing server-initiated elicitation/create

4. subscriptions/listen

Replaces GET+SSE and resources/subscribe; one opt-in POST stream, events tagged with a subscriptionId

5. tools/list

ttlMs / cacheScope cache hints (CacheableResult)

6. Legacy initialize

Proves the same server still answers a 2025-11-25 client (dual-mode SDK)
