How to Use the Copy.ai MCP in LangChain

Q: How do I handle Copy.ai workflow inputs in LangChain?

Use getworkflowdetails to fetch the exact JSON schema required for a specific run via the MCP Server. Your LangChain agent reads this schema and formats its prompt outputs to match the required fields before calling runworkflow.

Q: Can a LangChain agent search my Copy.ai workspace?

Yes, the agent calls searchworkflowsbyname to find matching templates. It then uses listfolders to filter workflows by organizational structure before starting a run.

Q: How does LangChain track long-running Copy.ai workflows?

The agent initiates the process using runworkflow and receives a run ID. It then runs a polling loop using getrunstatus until the state returns completed or failed.

Q: Can I access my brand voice profiles?

Yes, you call listbrandassets to retrieve your active voice profiles and info base items. This lets your agent inject specific brand contexts into your workflow runs.

Run multi-step Copy.ai content pipelines directly inside your LangChain reasoning loops.

Automate Copy.ai runs inside LangChain chains

The `run_workflow` and `get_run_status` tools let your LangChain agent execute content runs and track their execution state in real-time. Your chain won't have to guess if a generation finished because it polls the status and grabs the payload instantly. You feed these tools directly to your ReAct agent using the LangChain MCP adapter. The agent looks at the input schema requirements, triggers the workflow, and pipes the output directly into your next chain step.

Ground generations with Copy.ai brand assets

Your LangChain agent uses `list_brand_assets` and `get_workflow_details` to pull specific brand voices and info base items before kicking off a generation. Manual copy-pasting is dead; the agent pulls brand guidelines dynamically. By loading these assets directly into your chain context, you maintain brand voice consistency across thousands of automated pages. The agent matches the required workflow inputs with the correct asset ID dynamically.

Trace Copy.ai MCP Server runs in LangSmith

The `list_workflows` and `list_workflow_runs` tools give your LangChain agent full visibility into your workspace's active and past runs. Because this runs through our MCP Server, every tool call, latency spike, and payload transfer shows up in your LangSmith dashboard. You get a clear, step-by-step log of how your agent searches for workflows using `search_workflows_by_name` and runs them. These logs make it easy to debug your automated content pipelines.

Setup guide

Set up Copy.ai 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 Copy.ai 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({
    "copyai-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 Copy.ai transactions"
    })
    print(result["messages"][-1].content)
