Today we're launching the Paubox CLI. It allows developers and agents to send HIPAA compliant email from the command line.

 

Why We Built It

As part of our journey to become an AI-native company, we concluded that in addition to an MCP server, we also needed a CLI.

 

Install in 30 Seconds

 

 npm (all platforms)

Shell

npm install -g paubox-cli

 

Homebrew (macOS) 

Shell

brew tap paubox/paubox
brew install paubox-cli

 

 Windows 

Shell

Platform Support

The Paubox CLI runs on macOS, Linux, and Windows.

Platform Supported
macOS ✅
Linux ✅
Windows ✅

 

Tested on Node.js 18+. Install via npm:

Shell
npm install -g paubox-cli

 

Built for Agents Too

The Paubox CLI isn't just for humans. Any agent or automated workflow that can invoke a shell command can send HIPAA compliant email.

Shell
paubox send --to patient@example.com --subject "Your Dermatology appointment" --message "See you tomorrow at 2pm."

 

That means your AI agent can send a secure message to a patient without ever touching a web UI or managing an API client.

Paubox also offers an MCP server for agent frameworks that support the Model Context Protocol. This gives tools like Claude, Cursor, and others native access to HIPAA compliant email.

 

The Bigger Picture

If it can run a shell command, it can send HIPAA compliant email.

With Paubox :)
