Send Messages with Built-in Guardrails

Give your agent the power to communicate, but with safety on. It can use `send_sms` for alerts, `send_whatsapp` for customer updates, or `send_bulk_messages` for campaigns. The OpenAI Agents SDK provides guardrails, so you can review and approve actions before they're executed, preventing accidental sends. This isn't for toy projects. It's for building reliable applications where a mistake has real consequences. Your agent gets the tools it needs to act, and you get the controls to ensure it acts correctly. That’s how you ship agentic features to real users.

Audit Every Action with Full Tracing

Figure out exactly what your agent did and why. Every call to the Clickatell MCP Server, like checking a delivery with `get_message_status` or your credit with `get_account_balance`, shows up in your OpenAI tracing dashboard. You get a complete, step-by-step log of the agent's reasoning and tool use. No more black boxes. When a message fails or a balance looks wrong, you don't have to guess what happened. Just pull up the trace and see the exact request and response for tools like `list_message_history` or `get_account_info`.

Build Specialized Agents That Work Together

Break down complex messaging jobs and assign them to specialized agents. One agent can be an expert at managing templates using `list_whatsapp_templates` and `delete_whatsapp_template`. Another can handle media retrieval with `get_whatsapp_media`. The OpenAI Agents SDK lets these agents hand off tasks to each other. A 'template manager' agent can find the right template and pass its ID to a 'sending' agent. This MCP setup exposes granular tools perfect for creating a multi-agent system.

Setup guide

Set up Clickatell MCP in OpenAI Agents SDK

Prerequisites

Python 3.10+ installed
openai-agents package (pip install openai-agents)
Active Vinkius subscription with a valid endpoint token

1

Install the SDK

Run pip install openai-agents to install the OpenAI Agents SDK. The MCP integration is built-in — no extra dependencies needed.
2

Connect via SSE transport

Use MCPServerSse with your Vinkius endpoint URL. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com. The SDK auto-discovers all Clickatell tools at runtime.
3

Create your Agent

Pass the MCP to Agent(mcp_servers=[server]). The agent receives Clickatell tools as native definitions — JSON schemas resolve automatically.
4

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate Clickatell tools and returns structured results. Copy the full example on the right to get started.

agent.py

import asyncio
from agents import Agent, Runner
from agents.mcp import MCPServerSse

async def main():
    async with MCPServerSse(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    ) as server:
        agent = Agent(
            name="Clickatell Agent",
            instructions="You have access to Clickatell tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())

Common questions about Clickatell MCP in OpenAI Agents SDK

You connect it by passing the Vinkius MCP endpoint URL to the `MCPServerStreamableHttp` constructor in the SDK. The agent then auto-discovers all the available Clickatell tools, like sending SMS or checking your balance, with no extra configuration.

Your agent can send SMS and WhatsApp messages, check message delivery status, get your account balance, and manage your WhatsApp templates. The SDK's guardrails give you control over how and when the agent uses these Clickatell tools.

Yes. While the SDK auto-discovers all tools, you can implement your own logic to filter or restrict which tools an agent is allowed to invoke. This is a key part of building safe, production-ready agents.

There's a negligible latency increase from the Vinkius MCP Server, which handles auth and sandboxing. For most agentic workflows, the time spent on LLM inference is much greater, so you won't notice the difference in network time.

Your data, including message content, phone numbers, and account details, is processed in an ephemeral, single-use sandbox on Vinkius. The connection is secured, and OpenAI's tracing provides a full audit log of any data your agent accesses. Vinkius itself doesn't store your message data long-term.
