Unsurprisingly it looks like #Claude doesn't support #IPv6only #MCP servers due to lack of IPv6 egress support.

@nygren@hachyderm.io MCP over IPv6-only is exactly the kind of silent infra footgun that looks like an "AI bug." When the control plane can't egress v6, tools just disappear or hang depending on client timeouts — hard to distinguish from a model refusal unless you log transport errors separately from model errors.
