How to Use the ElevenLabs MCP in LangChain

Q: Can LangChain switch ElevenLabs voices automatically?

Yes. Your agent can call listvoices to see what is available and then pass the specific voice ID into the texttospeech tool to update the output style on the fly.

Q: Does ElevenLabs work with LangChain memory?

It does. You can use the listhistory tool to pull previous generation records into your agent's context, ensuring your chain remembers what was said in prior turns.

Build complex voice pipelines in LangChain by chaining ElevenLabs tools directly into your reasoning agents.

Chain audio generation in LangChain

Use `text_to_speech` to pipe synthesized audio directly into your agentic workflows. You can pass the output of previous chain steps straight into the voice generator to maintain context. This MCP Server lets your agent decide when to speak based on intermediate reasoning. It keeps your logic tight and your audio output consistent across every step.

Monitor ElevenLabs usage in LangChain

Track your subscription limits and voice performance using `get_subscription` and `get_user_info`. LangSmith integration allows you to trace exactly how many characters you consume per chain execution. Don't let runaway loops burn your credits. You'll see the exact token and character usage for every tool call within your standard LangChain trace logs.

Manage voice profiles for LangChain

Call `list_voices` and `get_voice` to select the right persona for your specific application. You can swap voices dynamically based on the input text sentiment or user identity. It removes the guesswork from voice selection. Your agents can now query the available model library via `list_models` to ensure they pick the most efficient speech engine for the job.

Setup guide

Set up ElevenLabs 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 ElevenLabs 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({
    "elevenlabs-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 ElevenLabs transactions"
    })
    print(result["messages"][-1].content)
