## What it is
signal-cli is an unofficial command-line, JSON-RPC, and D-Bus interface for the Signal messenger, supporting registering, verifying, sending, and receiving messages. It is primarily intended for servers to notify admins of important events, with a daemon mode exposing JSON-RPC and D-Bus interfaces.

## Use cases
- send signal messages from the command line
- notify admins of server events via signal
- integrate signal messaging into scripts and automation
- run a signal daemon with a JSON-RPC interface
- send and receive signal messages programmatically
- register and verify a signal account without the official app

## When to choose
- you need to automate Signal messaging on a server
- you want a scriptable or daemonized Signal client
- you need JSON-RPC or D-Bus integration for Signal

## When to avoid
- you need an official, fully supported Signal client
- you cannot keep the tool updated within three months of Signal server changes
- you need a graphical chat interface
