Sms Alert

This connects Claude to SMS Alert, a service for sending bulk SMS notifications to customers. You get pre-built actions for managing alerts, contact groups, and templates without handling auth yourself. The Membrane CLI does the heavy lifting: it manages credentials, refreshes tokens automatically, and lets you proxy raw API requests when the built-in actions don't cover your use case. Free tier is supported. Best for businesses that need to blast text alerts or marketing messages at scale and want Claude to handle the orchestration without storing API keys locally.

Install the CLI

Install the Membrane CLI so you can run membrane from the terminal:

npm install -g @membranehq/cli@latest

Authentication

membrane login --tenant --clientName=<agentType>

This will either open a browser for authentication or print an authorization URL to the console, depending on whether interactive mode is available.

Headless environments: The command will print an authorization URL. Ask the user to open it in a browser. When they see a code after completing login, finish with:
