3 SMS providers

from $0.10 per SMS

No KYC crypto payments

MCP stands for Model Context Protocol — an open standard that lets AI agents connect to external tools and services.

Think of it as a universal interface: you configure it once, and any compatible AI client can use the tools you've connected.

USB for AI

MCP is a standard plug. This server is a tool your agent can call, just like a function — no custom integration, no glue code.

Agent gets hands

Instead of just generating text, your agent can take real actions: buy a phone number, wait for an SMS, extract a code.

Works everywhere

Claude Desktop, Cursor, Windsurf — any MCP-compatible client. Add once, use from any agent on any platform.

Real-world use cases

How agents use it

Not a toy. These are real workflows running in production.

Automation

Bulk account creation

Your agent registers multiple accounts overnight. Each needs SMS verification. The agent loops autonomously — no human touches the keyboard.

# agent runs a loop over target services for svc in services: num = buy_number(service="twitter", country="any") code = get_sms(number_id=num.id) # agent enters code → account created release_number(number_id=num.id) ✓ done

Testing

Automated QA pipeline

Your CI/CD needs to test the SMS verification flow end-to-end. The agent handles the entire flow programmatically — no real phone, no manual steps.

# agent in test pipeline num = buy_number(service="your_app", country="us") trigger_sms_on_site(num.phone) result = get_sms(number_id=num.id) assert result.code != None ✓ verification flow works

Claude Desktop / Cursor

Personal Claude workflow

You're building a Claude workflow that needs to create accounts or verify identities on services that require a phone number. Drop in the MCP server — Claude handles SMS natively, without leaving the conversation. No separate scripts, no copy-pasting codes from your phone.

// Claude Desktop — natural language you: "Create a new Telegram account for the project" // Claude calls the tools itself → buy_number({ service: "telegram", country: "any" }) ← { phone: "+79151234567", number_id: "x9z" } → get_sms({ number_id: "x9z" }) ← { code: "54821" } ✓ account created, credentials saved

FAQ

Common questions

Which SMS providers are used?

5sim, SMS-Activate, and OnlineSim. The server queries all three in parallel and routes your request to whoever has the cheapest number available at that moment.

Your balance is not charged. Call release_number to cancel — the number is released back to the provider and your balance is refunded instantly. No risk.

Is this legal to use?

Yes. Virtual phone numbers for SMS verification are a legal, widely-used service. We do not support fraud, abuse, or any illegal activity.

How do I pay and top up?

Via CryptoBot. We accept USDT, TON, BTC, and ETH. Payments are instant, no KYC required, no account needed beyond your API key.

Can I use this with any AI agent?

Yes — any MCP-compatible client works: Claude Desktop, Cursor, Windsurf, and custom agents built with the MCP SDK. One config line, any platform.
