Sinch

This MCP server provides access to Sinch's communication APIs, enabling AI assistants to send messages across multiple channels (SMS, WhatsApp, RCS, email), manage voice calls and conferences, and perform phone number verification and lookup operations. Built by Sinch using TypeScript with the Model Context Protocol SDK, it offers 24+ specialized tools organized by service area including conversation messaging with multi-channel support and SMS fallbacks, email delivery through Mailgun integration, voice services with TTS callouts and conference management, and verification services with SMS-based OTP and number lookup capabilities. The implementation features tag-based tool filtering for different use cases (conversation, email, voice, verification, notification), comprehensive credential management with environment variable validation, webhook event tracking with SQLite storage, and robust error handling with region-aware API calls, making it valuable for customer communication workflows, automated notification systems, call center operations, and building AI assistants that need programmatic access to enterprise-grade communication infrastructure across multiple channels and regions.
