Automate content sequences in LangChain

Feed the output of your database queries directly into `create_generation` to build automated marketing workflows. You define the logic that triggers content creation based on real-time data events. LangChain handles the handoff between steps so your agent knows exactly when to execute `get_template` before generating copy. This keeps your reasoning chain tight and focused on specific campaign goals.

Monitor generation costs and usage

Track your token consumption and credit balance by calling `get_credits` inside your agent loop. It lets you build logic that halts production if your budget limits are reached. By checking `get_user_info` before any chain starts, you ensure the agent always operates with the correct account permissions. You get full visibility into every tool call via your existing tracing setup.

Manage content assets programmatically

Organize your generated drafts by using `create_folder` and `list_files` to maintain a clean project structure. You can script the movement of assets without manual intervention. Delete outdated variations with `delete_file` to keep your workspace clear. This MCP server acts as a direct interface for your LangChain agents to maintain a tidy content library.

Setup guide

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

Install the necessary adapters and use the MultiServerMCPClient to connect. You then pass the tools list directly into your agent constructor to start executing.

Yes, you can iterate through your templates using `list_templates` and queue them for generation. The framework manages the sequence and ensures each call completes before moving to the next task.

Your content drafts and account metadata remain private. We use token-based authentication and strict isolation, so your business data never leaks into other agent sessions.

It does, allowing your agents to trigger multiple generation requests in parallel. You can monitor the status of each job using `get_generation` to handle long-running tasks efficiently.

We only access the specific fields required for your generation requests, such as template parameters and folder paths. No raw user credentials are ever stored or indexed by your agents.
