CallSimple: give your agent a phone

CallSimple calls an Indian phone number with an AI voice that says it is an AI assistant calling for the user, delivers a message, asks up to 8 questions one at a time, then hangs up. About a minute later you get the summary, each answer and the transcript.

Use whichever is available. Check in this order:

1. MCP tools already present (place_call, get_call_result, list_recent_calls, get_balance, possibly prefixed like mcp__callsimple__place_call): use them.
2. Otherwise use the CLI (works in any agent with a shell):

   npx -y github:IndianAppGuy/callsimple-agent login      # opens the browser; new accounts get 2 free minutes
   npx -y github:IndianAppGuy/callsimple-agent balance
   

   If callsimple is installed globally (npm i -g github:IndianAppGuy/callsimple-agent), use callsimple <command> instead.
3. Or add the MCP server (remote, streamable HTTP, OAuth sign-in, no API key):
   • Claude Code: claude mcp add --transport http callsimple https://callsimple.app/mcp, then /mcp to sign in
   • Codex: codex mcp add callsimple --url https://callsimple.app/mcp, then codex mcp login callsimple
   • Any other client: server URL https://callsimple.app/mcp
