How to Use the AudioStack MCP in LangChain

Q: How do I chain AudioStack tools in LangChain?

First, get the tools using MultiServerMCPClient. Then, design your agent to call them in sequence. For example, use listvoices to get a voice ID, then pass that ID to the texttospeech tool. The output of one tool becomes the input for the next.

Q: Can I create a full audio ad with AudioStack and LangChain?

Yes. Your agent can take a script, use texttospeech for the voiceover, find background music with listsoundtemplates, and combine them into a final track using createaudioform. The whole process is one continuous chain.

Q: What's the best way to handle multiple audio files?

Use the listmediafiles tool to see what you've already uploaded or generated. Your agent can then decide whether to reuse existing audio or generate new clips, which saves processing time and cost.

Q: Can my LangChain agent check the status of a long audio job?

It can. After calling createaudioform or createstory, the tool returns a job ID. Your agent can then periodically call getaudioform with that ID to poll for the final audio URL when it's ready.

Automate Audio from Text to Final Mix

This MCP Server gives your LangChain agent a complete audio toolkit. You can build chains that find the right voice with `list_voices`, generate speech with `text_to_speech`, and pick background music using `list_sound_templates`. Because LangChain passes the output of one step to the next, your agent can make decisions along the way. It can check the details of a voice with `get_voice_details` before committing, then package everything into a final product with `create_audioform`. It's a full production line, automated.

Build Agents that Choose Voices & Music

Your agent can use the `list_voices` tool to find a voice that matches specific criteria like language or gender. It's not just a static call; the agent can parse the results and decide which voice ID is best for the job at hand. This is what makes a chain powerful. The agent can dynamically select a voice, then use `list_sound_templates` to find a complementary audio bed. The whole process is observable in LangSmith, so you see exactly why your agent chose one track over another.

Track Audio Generation with this MCP Server

The `get_usage_analytics` tool lets your agent check your account's consumption metrics. You can build this check directly into your audio generation chains as a guardrail. Before starting a large batch job with `create_story`, for example, you can have your agent call `get_usage_analytics` first. If the cost is too high or you're near a limit, the chain can stop and alert you. It's how you add financial controls to your automated workflows.

Setup guide

Set up AudioStack MCP in LangChain

Prerequisites

Python 3.10+ installed
langchain-mcp-adapters + langgraph packages
Active Vinkius subscription with a valid endpoint token

1

Install dependencies
Run pip install langchain-mcp-adapters langgraph langchain-openai. The MCP adapters package converts MCP tools into native LangChain BaseTool objects.
2

Connect via HTTP transport
Use MultiServerMCPClient with "transport": "http" pointing to your Vinkius endpoint. Replace [YOUR_TOKEN_HERE] with your token from cloud.vinkius.com.
3

Create a ReAct agent
Pass the discovered tools to create_react_agent() from LangGraph. The agent automatically routes AudioStack tool calls through the MCP protocol.
4

Run with any LLM
Swap ChatOpenAI for ChatAnthropic, ChatGoogleGenerativeAI, or any LangChain-compatible model. The MCP tools work identically across all providers.

agent.py

from langchain_mcp_adapters.client import MultiServerMCPClient
from langgraph.prebuilt import create_react_agent
from langchain_openai import ChatOpenAI

async with MultiServerMCPClient({
    "audiostack-mcp": {
        "transport": "http",
        "url": "https://edge.vinkius.com/[YOUR_TOKEN_HERE]/mcp",
    }
}) as client:
    tools = client.get_tools()

    agent = create_react_agent(
        ChatOpenAI(model="gpt-4o"),
        tools,
    )
    result = await agent.ainvoke({
        "messages": "List recent AudioStack transactions"
    })
    print(result["messages"][-1].content)

Your prompts and text for speech synthesis are processed inside a V8 Isolate sandbox on Vinkius. Every MCP Server request is ephemeral and uses a unique token, so the text you provide isn't stored after the audio is generated.
