Automate video lifecycle tasks in LangChain

You can trigger `initiate_upload` or `delete_video` within your chains to handle assets programmatically. This removes the need for manual dashboard work when your agent needs to process raw footage. Your chains maintain full visibility into every action. Since the MCP server provides structured outputs, you see exactly what happens during each step of the media pipeline.

Manage live streams via LangChain chains

Use `create_live_input` to spin up streaming endpoints on the fly. You define the metadata and recording settings right in your agent logic. Your agents can also query `list_live_outputs` to verify that simulcast targets are active. It keeps your streaming infrastructure in sync with your application state.

Handle captions and audio in LangChain

The agent can call `generate_caption` to automate transcriptions for new uploads. It takes the heavy lifting out of media accessibility. You can also use `copy_audio_track` to attach alternative audio to existing files. It makes complex media editing a simple task for your automated pipelines.

Setup guide

Set up Cloudflare Stream 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 Cloudflare Stream 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({
    "cloudflare-stream-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 Cloudflare Stream transactions"
    })
    print(result["messages"][-1].content)
