MCP’s biggest update removes the machinery many servers were built around

The upcoming MCP specification removes sessions and the initialization handshake, simplifying the protocol.

Per-request context and capability information will move into each call, while several core features are deprecated.

A new server/discover method is being added, and stateful workflows are expected to use explicit handles instead of hidden transport state.

The change makes MCP easier to run as a normal stateless network service, especially for remote servers.
