Sinch

Sinch is an MCP server that provides tools to interact with Sinch communication APIs directly through AI assistants like Claude Desktop. It connects large language models to Sinch services spanning conversation messaging, email delivery via Mailgun, phone verification, and voice calling. Developers and customer support engineers use this server to automate customer interactions across multiple channels without writing custom integration code for every operation. Through the server, users can trigger SMS, WhatsApp, and RCS messages using rich text, media, interactive choices, or predefined templates. It also enables checking number capabilities, handling two-factor SMS OTP verifications, placing text-to-speech voice callouts, and managing voice conferences. Additionally, the server integrates with email services to send template-based emails, retrieve delivery events, and monitor analytics metrics like open and click-through rates. Conversation applications, webhooks, RCS sender profiles, and WhatsApp Business templates can also be configured and inspected directly via natural language prompts.
