SMS for AI — Use Cases

Whatever your AI agent does, SMS for AI fits in. Here are the most common integration patterns — from Claude Desktop to LangChain to no-code automation.

🔐

OTP & Verification Codes

Your AI agent generates a one-time password and sends it via SMS — replacing costly dedicated OTP services. The agent calls POST /api/v1/sms/send with the code in the message body. Works with any user authentication flow.

Example agent prompt:

"Send a 6-digit OTP to +14155552671 and report the SMS ID."

Claude Desktop — Native SMS Tool

Add the SMS for AI MCP server to claude_desktop_config.json. Claude will immediately discover send_sms, get_balance, and list_sms as native tool calls. No code, no plugins — just one config entry.

{ "mcpServers": { "smsforai": {
  "url": "https://smsforai.com/api/mcp",
  "headers": { "Authorization": "Bearer YOUR_TOKEN" }
}}}

LangChain / CrewAI / AutoGen Agents

Wrap the REST API as a LangChain Tool, a CrewAI tool, or an AutoGen function. The agent can then decide when to send SMS as part of a multi-step workflow — e.g. "if the task is complete, notify the user by SMS."

import requests
from langchain.tools import Tool

def send_sms(payload: str) -> str:
    to, msg = payload.split("|", 1)
    r = requests.post(
        "https://smsforai.com/api/v1/sms/send",
        headers={"Authorization": "Bearer TOKEN"},
        json={"to": to, "body": msg}
    )
    return r.json()["sms"]["status"]

sms_tool = Tool(name="send_sms", func=send_sms,
    description="Send SMS. Input: 'phone|message'")

Telegram & Discord Bots with SMS Fallback

When users go offline on Telegram or Discord, your AI bot falls back to SMS for critical alerts. The bot calls POST /api/v1/sms/send with the user's saved phone number whenever a message cannot be delivered in-app.

Agent logic (pseudocode):

if not delivered_via_telegram:
    smsforai.send(to=user.phone,
                  body=f"Alert: {message}")

AI Customer Support — SMS Alerts

AI support agents send SMS summaries, ticket updates, escalation alerts, or appointment reminders to customers autonomously — without a human in the loop. The agent checks balance before sending and logs each SMS via the dashboard.

Example flow:

Ticket resolved → agent sends SMS "Your issue #1234 has been resolved." → logs outcome.

n8n / Make / Zapier — No-Code Automation

Add an HTTP node pointing to POST /api/v1/sms/send with your Bearer token. Combine with any trigger (webhook, CRM event, calendar alert) to send SMS without writing code. Works in any platform that supports custom HTTP requests.

n8n HTTP Request node config:

URL: https://smsforai.com/api/v1/sms/send
Method: POST
Headers: Authorization: Bearer TOKEN
Body: {"to":"{{phone}}","body":"{{message}}"}
