signal-cli is a command line interface for the Signal messenger. It supports registering, verifying, sending and receiving messages. signal-cli uses a patched libsignal-service-java, extracted from the Signal-Android source code. For registering you need a phone number where you can receive SMS or incoming calls. signal-cli is primarily intended to be used on servers to notify admins of important events. For this use-case, it has a daemon mode with D-BUS interface (man page) and JSON-RPC interface (documentation). For the JSON-RPC interface, there's also a simple example client, written in Rust.
