Chain documents in LangChain

Feed the output of your logic directly into `convert_url_to_pdf` to create reports on the fly. LangChain treats these results as standard nodes, letting you build multi-step flows where data flows from one task to the next. Your agent decides when to trigger these conversions based on its current state. You get full visibility into the process through your existing tracing setup, tracking every argument passed to the server.

Track usage within LangChain

Monitor your credits without leaving your execution environment using `get_cloudlayer_usage_stats`. It keeps your agent informed about remaining quotas during long-running chains. Prevent failures by checking limits before starting a heavy batch of document generation. Your agent can adjust its behavior dynamically if it detects that you are nearing your account cap.

Manage templates via LangChain

Pull specific document structures using `get_template_configuration` to ensure your PDF output matches your brand. You can map these templates to specific steps in your workflow. Use `list_pdf_templates` to view your library and select the right layout programmatically. This ensures your code remains clean while the agent handles the heavy lifting of document assembly.

Setup guide

Set up cloudlayer.io 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 cloudlayer.io 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({
    "cloudlayerio-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 cloudlayer.io transactions"
    })
    print(result["messages"][-1].content)
