SMS en Masse

A French SMS gateway that lets your AI agents send text messages and manage campaigns through the MCP protocol. Built by SMSenMasse, this connects to their REST API so Claude or other LLM tools can fire off SMS alerts, run marketing campaigns, or automate notifications without you writing integration code. The service also offers n8n and Zapier connectors if you want no-code workflows, but the MCP server is the direct path for AI-driven messaging. You'd reach for this when building customer support bots that need to send verification codes, automated appointment reminders, or any scenario where your agent needs to bridge the gap between conversation and actual SMS delivery. Ships with 20 free credits to test it out.
