One API for every message your product sends
OTP, number lookup, SMS, WhatsApp, email, voice and conversation threads behind one key. Plus an MCP server, so your AI agents can send them too.

What's different about Techalpha
The parts teams usually build themselves come with the API.
One MCP server for every channel
Connect once and your AI agent can verify users, look up numbers, send on any channel and reply in threads. No separate server per channel.
- verify_start
- lookup_number
- sms_send
- whatsapp_send
- email_send
- call_start
- conversation_reply
Every reply lands in one thread
SMS, WhatsApp, email and voice with the same person share one conversation, so your team and your agents read one history.
Fallback when a channel fails
Set a fallback once. If an SMS isn't delivered, Techalpha tries WhatsApp, or the other way round, without another call from your code.
Seven building blocks, one key
Start with the one you need today. Every product shares the same authentication, the same delivery events and the same conversation thread, so adding a channel later is one more call.
Let your AI agents send the message
The Techalpha MCP server gives AI agents the same tools your code gets. Ask in plain words, and the agent checks the number, picks the channel and sends.
Every channel on one server
OTP, lookup, SMS, WhatsApp, email, voice and threads from a single MCP connection.
It reads replies too
Agents can open a conversation thread and answer with the full history in view.
Works where you build
Connect from Claude, Cursor, VS Code or any client that supports remote MCP servers.
Send Emily her login code. If she's not on WhatsApp, use SMS.

Done. Emily's code was delivered on WhatsApp a few seconds ago. I'll check it when she enters it.
