@joltsms/mcp-server
MCP server for JoltSMS — provision dedicated real-SIM US phone numbers and receive SMS/OTP codes through AI agents.
Built on the Model Context Protocol, this server gives AI agents (Claude Code, Claude Desktop, Cursor, etc.) the ability to rent phone numbers, wait for incoming SMS, extract OTP codes, and manage billing — all through standardized tool calls.
Quick Start
1. Get an API Key
Create a JoltSMS account and generate an API key at Dashboard → Settings → API Keys.
2. Configure Your MCP Client
Add to your .mcp.json (Claude Code) or MCP settings (Claude Desktop, Cursor):
{
"mcpServers": {
"joltsms": {
"command": "npx",
"args": ["-y", "@joltsms/mcp-server"],
"env": {
"JOLTSMS_API_KEY": "jolt_sk_your_key_here"
}
}
}
}
3. Use It
Your AI agent now has access to all JoltSMS tools. Try:
"Provision a new phone number with area code 650 and wait for an OTP"

OTP Verification Workflow
The most common use case — automated phone verification:
1. joltsms_provision_number({ area_code: "650" })
→ Number provisioning started! Phone: +16505551234
2. joltsms_update_number({ number_id: "+16505551234", service_name: "PayPal" })
→ Tagged for easy lookup later
3. [Agent enters phone number on PayPal and requests OTP]
4. joltsms_wait_for_sms({ number_id: "+16505551234", timeout_seconds: 120 })
→ SMS received after 8.2s: "Your PayPal code is 847291"
→ OTP Code: 847291
5. joltsms_mark_read({ number_id: "+16505551234" })
→ Inbox clean
6. [Agent enters 847291 on PayPal — verification complete]
