How to Use the Volcengine Speech Synthesis MCP in OpenAI Agents SDK

Q: How do I check if a long audio synthesis job failed using Volcengine Speech Synthesis and OpenAI Agents SDK?

You monitor the process by calling gettaskstatus. This tool returns whether your background TTS task is currently processing, completed successfully, or if it encountered an error. It's key for building reliable agent workflows.

Q: What are the supported audio formats when using Volcengine Speech Synthesis and OpenAI Agents SDK?

The getaudioformats tool lists all options. You can use MP3 for web delivery, WAV if you plan to edit the file later, or OGG Opus for efficient streaming directly into your application.

Q: Can I list available voices before using Volcengine Speech Synthesis and OpenAI Agents SDK?

Absolutely. The listvoices tool lets you see every voice model available right out of the gate. It's crucial for deciding between a standard male, female, or even one of those famous TikTok voice styles.

Q: If I need to use multiple languages with Volcengine Speech Synthesis and OpenAI Agents SDK, which tool do I call?

Use synthesizespeech. This tool supports Chinese, English, and Japanese. You can also adjust the speed and volume parameters right in the request, making it highly versatile for multi-language support.

Perplexity

Generate Custom Voices with the MCP Server

The `create_custom_voice` tool trains a unique voice model using 10 to 50 high-quality audio recordings. This process takes one to three days, and once done, you use the custom voice type in your synthesis calls. You'll then call `synthesize_speech` using that specific voice ID to generate content. The result is a professional, proprietary sound signature that makes your agent feel like it belongs to your brand.

Synthesizing Long Content for OpenAI Agents SDK

When you have articles or lengthy documentation, don't hit the 1024 character limit. Use `synthesize_long_text` instead; it handles text that exceeds the standard length. This is perfect for building audiobooks or detailed educational content within your agent system. It ensures that large bodies of text convert to speech without breaking the flow.

Controlling Tone and Timing with MCP Server

You need precise narration? The `synthesize_ssml` tool lets you use SSML tags like `<break>` or `<emphasis>`. This gives your agent direct control over timing, intonation, and rhythm. This level of granular control is essential for accessibility features or character-driven dialogue. It moves the output far beyond basic text-to-speech.

Setup guide

Set up Volcengine Speech Synthesis 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 Volcengine Speech Synthesis tools at runtime.
3

Create your Agent

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

Run the agent

Call Runner.run(agent, prompt) to execute. The agent invokes the appropriate Volcengine Speech Synthesis 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="Volcengine Speech Synthesis Agent",
            instructions="You have access to Volcengine Speech Synthesis tools.",
            mcp_servers=[server],
        )
        result = await Runner.run(agent, "List recent transactions")
        print(result.final_output)

asyncio.run(main())
