CallSimple is an AI phone-calling service run by Indianappguy Tech Pvt Ltd (Bengaluru, India). You tell ChatGPT or Claude (or the web app) who to call and what to say; CallSimple's AI voice calls them from an Indian +91 number in Hindi or English, delivers the message, asks your questions and reports back what they said. It is offered as an MCP server (https://callsimple.app/mcp) that users add as a custom connector in Claude or a custom MCP app in ChatGPT, with prepaid call packs billed only when the callee picks up.
