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

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 LangChain connect to MCP servers?
Use langchain-mcp-adapters to create an MCP client. LangChain discovers all tools and wraps them as native LangChain tools compatible with any agent type.
Which LangChain agent types work with MCP?
All agent types including ReAct, OpenAI Functions, and custom agents work with MCP tools. The tools appear as standard LangChain tools after the adapter wraps them.
Can I trace MCP tool calls in LangSmith?
Yes. All MCP tool invocations appear as traced steps in LangSmith, showing input parameters, response payloads, latency, and token usage.
