The new Courier CLI brings your notification infrastructure directly into AI agent workflows like Cursor and Claude Code. Developers can send messages, debug issues, and manage notifications straight from the terminal, enabling faster iteration and automation.
With support for both CLI commands and MCP integrations, teams can choose how agents interact with Courier in structured or flexible ways. It’s the fastest way to build, test, and manage notifications alongside your code.
