MCP server
Your assistant writes in WhatsApp.From your number, and it reads the replies.
Add one address to any app that supports the Model Context Protocol and sign in with your OTPRun account. Your assistant can then message people by name, wait for their answers, ask businesses for prices and remind your family, all from your own WhatsApp.
The free plan includes one WhatsApp number. No card required.
What you get
Messages and replies
Send to one person or to fifty at once, wait for an answer and read the whole conversation, including what you typed on the phone yourself.
Contacts by name
The address book understands names and aliases, so a request like "write to my wife" works. Contacts can be imported from your phone in one step.
You stay in control
Access is granted with OAuth and can be revoked at any time. Choose whether the assistant sees all chats or only the ones it wrote to.
One request
Most apps only need the server address. Those that use a configuration file accept this block; sign-in opens in the browser.

Approve access in your account, then ask the assistant to send the first message.
Questions
Which apps can connect?
Any app that supports remote MCP servers over streamable HTTP. Apps that only call HTTP actions can import the public OpenAPI schema instead, and there is a plain-text guide at /llms.txt.
What can the assistant do?
Send messages and reminders, read replies and conversations, find and save contacts, run small campaigns, check if numbers are on WhatsApp and send verification codes.
Is it safe to give access to my WhatsApp?
The assistant never sees your WhatsApp session, only the actions you approve. You can limit it to the chats it started and revoke access in one click.
Do I need an API key?
No, signing in with OAuth is enough. An API key also works for apps that only accept a header or an address with a key.
Ten minutes to the first code.One key, one call, done.
Create a workspace, link a number or use the Telegram bot, and send the first verification from the dashboard.
