Connect iMessage (through SendBlue) to Claude Code

What you need:

• A SendBlue account (free sandbox to test, AI Agent line $100 a month)
• SendBlue API key and secret, saved in the app's secret store
• Opt in from each person before your first text
• Node.js on the computer that runs the server (it starts with npx)

Plan: A Claude Code login.

1. Create a SendBlue account. The free sandbox is for tests: up to 10 verified contacts, no first texts, no webhooks. A real line is the AI Agent plan, $100 a month per line.
2. Get your SendBlue API key and secret from the dashboard.
3. In your own terminal (not in a chat): export SENDBLUE_API_API_KEY=your-key and export SENDBLUE_API_API_SECRET=your-secret
4. Run: claude mcp add sendblue_api -- npx -y sendblue-api-mcp
5. Start claude and type /mcp to check SendBlue is there.

Test it: Ask: show my 3 newest iMessage threads in SendBlue. Don't send anything.

What it can do: Send and read iMessage, SMS and MMS from your SendBlue line. Check if a number has iMessage.

What it can't do: Only text people who opted in. SendBlue's terms ban cold texts. The free sandbox can't send first texts or use webhooks.

Only text people who opted in. SendBlue's terms ban unsolicited texts, and so do TCPA and CASL. Open question for SendBlue: can an AI Agent line send the first text to an opted in person who hasn't texted it yet? Its pricing page says inbound first, its limits page says 200 outbound first contacts a day.

Never paste an API key into a chat. Use the app's connector screen.
