How to Use the Conductor (Netflix OSS) MCP in LangChain

Q: Can I trace Conductor (Netflix OSS) tool calls with LangSmith in my LangChain setup?

Yes, every execution of executeworkflow or gettasklogs goes through the standard adapter. LangSmith captures the exact inputs, outputs, and latency for every single tool call.

Q: What is the best way to run bulk operations like bulkpause in LangChain?

Pass the server tools to createagent and let the ReAct loop gather the list of workflow IDs. The agent then calls bulkpause in a single step once it compiles the target list.

Run multi-step Netflix Conductor workflows directly inside your LangChain reasoning loops.

Run Conductor tasks inside LangChain chains

Connecting your LangChain agent to this MCP Server lets you run and manage workflows using `start_workflow` and `get_workflow_tasks`. When a step in your chain finishes, the agent inspects the output and triggers the next task dynamically. LangSmith traces every single execution step, giving you complete visibility over latency and inputs. You can chain these steps with your existing SQL databases or vector stores to handle complex decision trees.

Handle bulk Conductor failures using LangChain agents

By exposing `bulk_retry` and `bulk_restart` to your LangChain ReAct agents, this server makes recovery painless when things go wrong. Instead of manual intervention, your agent scans failed runs and issues bulk commands based on the error patterns it detects. You get a LangChain recovery loop that connects your monitoring integrations directly to Conductor status checks. The agent decides whether to pause, retry, or terminate based on live execution logs.

Update Conductor definitions using LangChain tools

Your LangChain agent can modify workflow structures on the fly using this server's `update_workflow_definitions` and `validate_workflow_definition` tools. The agent runs validation checks on new task structures before saving them to your cluster. This prevents broken Conductor definitions from hitting your production namespace. By feeding validation errors back into the chain, the agent corrects its own syntax mistakes in real-time.

Setup guide

Set up Conductor (Netflix OSS) 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 Conductor (Netflix OSS) 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({
    "conductor-netflix-oss-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 Conductor (Netflix OSS) transactions"
    })
    print(result["messages"][-1].content)
