Bring Onewaysms
to OpenAI Agents SDK
Learn how to connect OneWaySMS to OpenAI Agents SDK and start using 11 AI agent tools in minutes. Fully managed, enterprise secure, and ready to use without writing a single line of code.
What is the OneWaySMS MCP Server?
Connect your OneWaySMS account to any AI agent and take full control of your global SMS orchestration through natural conversation. OneWaySMS provides a reliable and high-speed gateway for business messaging, and this integration allows you to send standard or Unicode SMS, monitor credit balances, and track delivery statuses directly from your chat interface.
What you can do
- SMS & Messaging Orchestration — Send individual or bulk text messages programmatically to ensure your alerts and notifications are always synchronized.
- Unicode & Multilingual Support — Dispatch messages using standard ASCII or Unicode (for special characters and emojis) via natural language to reach your global audience.
- Credit & Balance Intelligence — Access and monitor your available SMS credit balance directly from the AI interface to ensure uninterrupted service.
- Transaction & Delivery Control — Retrieve real-time delivery status for any message using its unique Transaction ID (MTID) using simple AI commands.
- Operational Monitoring — Track system responses and manage regional gateway settings to ensure your communication pipeline is always optimized.
How it works
1. Subscribe to this server
2. Enter your OneWaySMS API Username and API Password from your dashboard
3. Start managing your SMS communications from Claude, Cursor, or any MCP-compatible client
No more manual logging to check if a message was delivered. Your AI acts as a dedicated messaging coordinator or operations assistant.
Who is this for?
- Operations Managers — quickly send emergency alerts and monitor credit usage without switching apps.
- Customer Success Teams — automate the delivery of status updates and track message reception via natural conversation.
- Developers — integrate real-time SMS capabilities and balance tracking directly within the chat.

Why teams choose Vinkius for OneWaySMS in OpenAI Agents SDK
The OneWaySMS MCP Server runs on Vinkius-managed infrastructure inside AWS — a purpose-built runtime with per-request V8 isolates, Ed25519 signed audit chains, and sub-40ms cold starts. All 11 tools execute in hardened sandboxes optimized for native MCP execution.
Your AI agents in OpenAI Agents SDK only access the data you authorize, with DLP that blocks sensitive information from ever reaching the model, kill switch for instant shutdown, and up to 60% token savings. Enterprise-grade infrastructure, zero maintenance.

How Vinkius secures
OneWaySMS for OpenAI Agents SDK
Every tool call from OpenAI Agents SDK to the OneWaySMS MCP Server is protected by DLP redaction, cryptographic audit chains, V8 sandbox isolation, kill switch, and financial circuit breakers.
Frequently asked questions
Can my AI automatically find the delivery status for a specific SMS by its transaction ID?
Yes! Use the get_status tool with the Transaction ID (MTID). Your agent will respond with the current delivery state (e.g., Delivered, Failed, or Pending) in seconds.
How do I find my OneWaySMS API Username and Password?
Log in to your OneWaySMS dashboard, navigate to the API section, and you will find your dedicated API Username and API Password (which are different from your web login).
What is the character limit for ASCII vs Unicode messages?
Standard ASCII messages allow up to 160 characters per SMS. Unicode messages (which support special characters and emojis) are limited to 70 characters per SMS.
How does the OpenAI Agents SDK connect to MCP?
Use MCPServerSse(url=...) to create a server connection. The SDK auto-discovers all tools and makes them available to your agent with full type information.
Can I use multiple MCP servers in one agent?
Yes. Pass a list of MCPServerSse instances to the agent constructor. The agent can use tools from all connected servers within a single run.
Does the SDK support streaming responses?
Yes. The SDK supports SSE and Streamable HTTP transports, both of which work natively with Vinkius.
