How to Use the Volcengine Speech Synthesis MCP in Google ADK

Q: How do I check task status with Volcengine Speech Synthesis and Google ADK?

You use the gettaskstatus tool. This allows your agent to poll the server, confirming if a large-scale text conversion is still processing, finished, or failed. It's critical for building robust workflows that wait on async tasks.

Q: What audio formats does Volcengine Speech Synthesis support with Google ADK?

The getaudioformats tool shows you the options: MP3 works well for web embeds, WAV is best if you need to edit the file locally, and OGG Opus is great when streaming data efficiently.

Q: Does Volcengine Speech Synthesis support advanced timing control with Google ADK?

Yes. The synthesizessml tool allows you to use SSML markup, giving precise instructions on pacing and emphasis using tags like and . You get professional-grade voice control.

List Available Voices using the MCP Server

The `list_voices` tool gives your agent a full inventory of available TTS voice models. This is essential for determining which voice best matches the context of the information pulled from BigQuery or Vertex AI. You can quickly check not only standard voices but also those trendy styles, ensuring your enterprise output maintains a consistent and high-quality sound signature.

Synthesize Speech with Google ADK

The `synthesize_speech` tool converts text to speech. It handles multiple languages (Japanese, Chinese, English) and various styles—from formal news reads to casual dialogue. You can also fine-tune the output by setting specific speed or volume parameters. It's ideal for feeding audio narratives into a user experience that already relies on Google Cloud infrastructure.

Creating Custom Voice Models with MCP Server

If standard voices aren't enough, use `create_custom_voice`. This tool trains a voice model using 10 to 50 recordings of one speaker. The process takes time—one to three days—but the resulting custom voice dramatically enhances your agent's brand identity. The new voice type is then available for subsequent calls via `synthesize_speech`.

Setup guide

Set up Volcengine Speech Synthesis MCP in Google ADK

Prerequisites

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

1

Install Google ADK

Run pip install google-adk to install the Agent Development Kit. MCP support is included via the McpToolset class.
2

Connect via SSE transport

Use McpToolset.from_server() with SseServerParams pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create an LlmAgent

Pass the returned mcp_tools list directly to LlmAgent(tools=mcp_tools). The ADK maps each MCP tool to a native Gemini function call — no manual schema definitions required.
4

Run with any Gemini model

The agent works with any Gemini model (gemini-2.0-flash, gemini-2.5-pro, etc.). Copy the full example on the right to get started with Volcengine Speech Synthesis tools in your ADK agent.

agent.py

from google.adk.agents import LlmAgent
from google.adk.tools.mcp_tool.mcp_toolset import McpToolset
from google.adk.tools.mcp_tool.mcp_session_manager import SseServerParams

# Connect to the MCP via SSE
mcp_tools, exit_stack = await McpToolset.from_server(
    connection_params=SseServerParams(
        url="https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp"
    )
)

# Create your agent with auto-discovered tools
agent = LlmAgent(
    name="Volcengine Speech Synthesis_agent",
    model="gemini-2.0-flash",
    instruction="You have access to Volcengine Speech Synthesis tools via MCP.",
    tools=mcp_tools,
)
