Send WhatsApp, SMS & email from Claude

Connect SendAPI to Claude Code and Claude Desktop with one command. Then just ask Claude to message a customer, send an OTP, or fire off an email — it calls the tools for you.

Connect Claude to SendAPI

claude mcp add --transport http sendapi https://sendapi.co/mcp \
  --header "Authorization: Bearer sk_live_xxxxxxxx"

Then just ask

• "Send a WhatsApp to +14155550100 letting them know their order shipped."
• "Email all the addresses in this CSV a personalised onboarding note."
• "Send a 6-digit OTP to this number and tell me the verification id."

What you can build with Claude

• Customer ops in chat — Resolve a support thread and notify the customer over WhatsApp without leaving Claude.
• Bulk outreach from a file — Point Claude at a spreadsheet and have it draft and send personalised emails in one pass.
• Verification flows — Spin up OTP send-and-check while prototyping an auth flow, all from the chat.
