JoltSMS

by rchanllc

Rent a dedicated real-SIM US number, wait for the SMS, and get the OTP parsed out of it.

Telephony, SMS & Voice AgentsVerified
Summary
The OTP wall, crossed without a person holding a phone.

The flow is the product: rent a number, tag it with the service it is for, wait until the SMS lands, take the code out of it. Because the lines are dedicated real SIMs rented monthly rather than pooled, the same number is still yours the next time that service texts you.

What it is

A phone-number service for agents. The numbers are dedicated real-SIM US lines rented monthly, and the tools are shaped around the verification flow: provision, wait, read the parsed code, clear the inbox.

What you get
  • A dedicated real-SIM US number provisioned by area code, at $50 per month
  • A poll that waits for an incoming SMS on a number, with a timeout you set
  • The most recent parsed OTP code from a number, as a one-call shortcut
  • Recent messages listed with sender, body and the parsed code where one was detected
  • Numbers labelled, tagged and annotated, so the one you rented for a service is findable later
  • Messages marked read singly or in bulk
  • Numbers released — they stay active to the end of the current billing period
  • Billing and subscription status for every number, with billing health
Requirements

A JoltSMS API key as JOLTSMS_API_KEY, generated in the dashboard, and npx to launch it. Provisioning a number requires a payment method on file and costs $50 per month.

Setup effort

One command plus a key — npx -y @joltsms/mcp-server, then supply credentials
