         * <a name="connect_proxy_allow_managed_registration"></a><a href="#connect_proxy_allow_managed_registration">`allow_managed_api_registration`</a> Allows managed proxies to be configured with services that are registered via the Agent HTTP API. Enabling this would allow anyone with permission to register a service to define a command to execute for the proxy. By default, this is false to protect against arbitrary process execution.
