Summary
Connects to Telnyx's communications API with tools split across three domains: billing (balance checks, invoices, charge breakdowns), phone number management (listing, searching available numbers, purchasing), and messaging (sending SMS, listing message history, managing profiles). Requires a Telnyx API key from your portal account. Reach for this when you're building workflows that need to programmatically manage telecom infrastructure, like automated number provisioning for new customers, monitoring messaging costs across campaigns, or sending transactional SMS without leaving your Claude environment. The billing tools are especially handy for keeping tabs on usage before it shows up on your invoice, with support for date-range queries up to 60 days.
