How to Use the Elai AI Video MCP in LangChain

Q: How do I pass Elai AI Video asset IDs through a LangChain state?

You store the output of listavailableavatars or listavailablevoices directly in your LangGraph state. The agent reads these values and passes them as arguments to the createnewaivideo tool in the next node.

Q: Can LangChain handle asynchronous rendering with the Elai AI Video MCP Server?

Yes. Your agent calls triggervideorendering to start the job, then uses a routing node to poll getvideodetails until the status field confirms the render is finished.

Q: How does LangSmith help debug Elai AI Video tool failures in a LangChain setup?

LangSmith traces the exact JSON payloads sent to createnewaivideo. If the rendering fails, you can see if the agent passed an invalid script or a mismatched voice ID.

Build LangChain pipelines that write scripts, select avatars, and render Elai AI videos in a single observable chain.

Perplexity

Chain script generation with avatar selection

LangChain agents can feed the output of a prompt directly into Elai's video creation tool. Your agent runs `list_available_avatars` and `list_available_voices` to match the tone of your generated text, then feeds those exact IDs straight into `create_new_ai_video`. No manual copy-pasting of asset IDs between steps. You can track this entire data flow inside LangSmith. If an avatar ID is invalid or a voice is unsupported, the tracing logs show you exactly which tool in the chain failed before the video gets sent for rendering.

Automated rendering loops in LangGraph

Standard chains struggle with asynchronous API tasks like video rendering. This MCP Server lets your LangChain agent call `trigger_video_rendering` and transition into a monitoring state. The agent polls `get_video_details` in a controlled loop to check the status without locking up your main application thread. Once the status switches to completed, the agent pulls the final link from `list_successfully_rendered_videos`. This turns a slow, manual rendering queue into a hands-off background worker driven entirely by your agent's decision-making logic.

Budget-conscious MCP Server workflows

Prevent your automated chains from burning through your rendering budget. Before initiating a new video run, your LangChain agent calls `get_elai_account_metadata` to check your remaining credit balance. If the credits are low, the agent can route the workflow to an alert tool instead of calling `create_new_ai_video`. This keeps your automated pipelines safe from unexpected overages and API limits.

Setup guide

Set up Elai AI Video 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 Elai AI Video 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({
    "elai-ai-video-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 Elai AI Video transactions"
    })
    print(result["messages"][-1].content)

Common questions about Elai AI Video MCP in LangChain

You store the output of `list_available_avatars` or `list_available_voices` directly in your LangGraph state. The agent reads these values and passes them as arguments to the `create_new_ai_video` tool in the next node.

Yes. Your agent calls `trigger_video_rendering` to start the job, then uses a routing node to poll `get_video_details` until the status field confirms the render is finished.

LangSmith traces the exact JSON payloads sent to `create_new_ai_video`. If the rendering fails, you can see if the agent passed an invalid script or a mismatched voice ID.

Yes, you can easily combine them. For instance, you can chain a database tool to fetch product data, feed that text into a prompt, and then use the MCP Server to build the final video using `list_video_templates`.

Your video scripts and account metadata are processed through Vinkius's isolated sandbox. The credentials never touch the LangChain client directly, meaning your raw text scripts and API tokens remain protected during execution.
