Platfone MCP Server

Platfone provides virtual phone numbers for account verification, testing, and automation workflows. The Platfone MCP server enables AI agents to obtain temporary numbers and receive SMS messages from MCP-compatible clients like Claude, VS Code Copilot, Codex, etc.

Why MCP?

Instead of manually integrating the API, AI agents can:

• Order numbers autonomously by country and service name
• Wait for SMS codes
• Retry or cancel activations

All via structured tool calls — no custom backend required.

Features

• Full activation lifecycle — from ordering a number to receiving SMS
• ETag-cached catalog — countries and services are cached in-memory with 5-minute TTL and ETag-based conditional refresh — never sent to the agent
• Human-friendly inputs — use "Israel" or "Telegram" instead of IDs; names are auto-resolved server-side
• Dual transport — stdio and http from a single codebase
• API key auth — works with your existing Platfone API key

Installation

See the full Installation Guide for detailed instructions.

Quick Start

NPM:

PLATFONE_API_KEY=your_key npx @platfone/mcp

Agent Guidelines

• Always call check_price first to verify cost and availability
• Then call order_number to rent a number
• Call check_sms until SMS is received or expired
• Use retry_activation if no SMS arrives
• Use cancel_activation to release funds if no longer needed

Tools

| Tool | Description | | ------------------- | --------------------------------------------------------------------------------------------------------- | | get_balance | Check account balance: total, reserved, and available funds. | | check_price | Check pricing and availability for a country + service pair before ordering. | | order_number | Order a virtual phone number. Accepts names ("Israel") or IDs ("il"). Returns activation_id + phone. | | check_sms | Poll activation state. Returns SMS code when received, or current status with polling instructions. | | retry_activation | Request another SMS on the same number. Free of charge. | | cancel_activation | Cancel an active activation before SMS is received. Refunds reserved amount. |

Note: Country and service catalogs are cached server-side and auto-resolved from human-readable names. The agent never receives the full catalog — only resolved IDs or disambiguation hints.

Typical AI Agent Flow

1. check_price         (country: "Israel", service: "Telegram")  → verify cost & availability
2. order_number        (country: "Israel", service: "Telegram")  → returns activation_id + phone
3. check_sms           (activation_id)                            → poll or check once for SMS

Optional steps:

• retry_activation — request another SMS on the same number (free)
• cancel_activation — cancel before SMS arrives (refunds balance)
