Two majors. The compile break is trivial — `stateful_mode` became
`legacy_session_mode` and now defaults to true, so the assignment is deleted
rather than renamed. Per SEP-2567 it only applies to protocol versions
< 2026-07-28 anyway; newer clients are served statelessly regardless.
The part that mattered does not fail to compile. rmcp 3.x added inbound
`Host` validation defaulting to ["localhost", "127.0.0.1", "::1"] — a DNS
rebinding guard aimed at servers running on a developer's own machine. This
server is the other kind: `--http` binds 0.0.0.0:8081, ships as
ghcr.io/goplasmatic/orion-cli, and is listed in the MCP registry for remote
clients. Taken silently, that default would have rejected every request
arriving under any name but loopback.
Measured rather than reasoned about, by building both ways and posting a
real `initialize` at each:
Host: localhost:8099 200 200
Host: mcp.example.com 403 200
default disable_allowed_hosts()
So `disable_allowed_hosts()` restores exactly the reachability rmcp 1.x had.
It weakens nothing that was previously enforced — there was no Host check
before — but it does decline a new protection, deliberately and in one
commented place rather than by omission.
The protection is worth having later. It needs an operator-supplied hostname
to mean anything, which means a repeatable `--allowed-host` flag and a
decision about breaking existing deployments that pass none. That is a
feature with a CLI surface, not a dependency bump, and not something to slip
into 1.0 unannounced.

Looks like rmcp is up-to-date now, so this is no longer needed. |
