Twilio

Connects Claude to Twilio's REST API for programmatic SMS and voice operations. You get five tools: send SMS messages, list and retrieve message details with filtering by phone number, list call history, and initiate outbound calls using TwiML URLs. Hosted by Pipeworx as a streamable HTTP server, so no local setup required. Useful when you need Claude to send notifications, pull communication logs for analysis, or trigger calls based on conversational context. The ask_pipeworx wrapper lets you query in natural language instead of calling tools directly, though standard MCP tool calls work fine too.
