Perplexity

Automate mass SMS alerts with Cascade

`send_bulk_sms` lets your AI client fire off texts to 164 E.164 numbers in one single request. Cascade reads your recipient list, spots formatting errors, and executes the batch job without waiting for your permission. You get a job ID and a detailed status array for every phone number. If some numbers fail, Cascade reads the response and automatically triggers `get_message_status` to debug the specific delivery failures.

Manage shortcodes and keyword flows in Windsurf

`create_shortcode` provisions a new marketing shortcode and gives you a clear activation timeline. Cascade sets up the keyword triggers, then reads the active configurations using `get_keyword_responses` to verify your opt-in flows. When a campaign ends, the MCP Server cleans up by invoking `delete_shortcode` to decommission the number. You don't have to write custom teardown scripts or click through web dashboards to retire old campaigns.

Audit inbound customer messages on the fly

`get_inbound_messages` retrieves sender numbers, message bodies, and matched keywords from your customers. Cascade chains this tool with your workspace code to log customer interactions or handle STOP commands automatically. You can also use `list_messages` to pull historical logs for compliance auditing. Cascade parses the timestamps and content snippets to build clean markdown reports right in your editor.
