Windows 实测：绑 0.0.0.0 后局域网请求被 mcp DNS 重绑定防护 421 拒。 - parse_args 加 --allowed-hosts（逗号分隔 Host 白名单，默认 None 保持 mcp 仅 localhost 族行为） - build_server(manager, allowed_hosts=...) 经 TransportSecuritySettings 传入（mcp 1.29.0 API 与设计一致，无需调整） - main() 逗号拆分（去空白、丢空段） - 回归测试：TestClient 驱动真实 ASGI app（含 lifespan）， Host=192.168.61.35:8972 initialize → 200；Host=evil.example.com → 421 Co-Authored-By: Claude <noreply@anthropic.com>
