Perplexity

Run SMS Campaigns from Claude Desktop

The CallFire MCP Server connects your AI directly to your messaging pipeline. You just tell Claude to blast out a text, and it executes `send_sms` immediately. There's no logging into a separate dashboard to fire off quick updates to your customer list. Your agent tracks the aftermath using `list_sent_sms` and `get_sms_details`. When someone replies, Claude checks the delivery status and reads the response data right in your chat window. You get the whole picture without ever opening a browser tab.

Trigger and Audit Voice Calls via MCP Server

Voice operations usually mean clicking through bloated web interfaces. Now you type a prompt, and the MCP Server hits `send_voice_call` to dial a number on demand. It plays your pre-configured audio files automatically over the phone. Debugging failed calls takes seconds instead of minutes. Claude pulls the exact error codes via `get_call_details` or lists your recent dial history with `list_calls`. You see exactly why a number bounced without leaving the prompt.

Monitor Account and Webhook Health

Managing campaign infrastructure means keeping tabs on your rented numbers and callbacks. Your agent runs `list_keywords` to see which short codes you currently own. It knows exactly what assets are available for the next big push. Broken integrations kill campaigns fast. Claude checks your active event listeners using `list_webhooks` and verifies your billing status via `get_account_info`. You fix configuration issues before they drop important messages.
