Chaining Zoho Invoices in LangChain

Your agent can build complex billing sequences. Start by calling `list_organizations` to confirm the correct company ID, then use that ID to list all relevant invoices via `list_invoices`. The output of this first step becomes the input for your next tool call.

Automating Contact Discovery

Need customer data before invoicing? Your chain can execute `list_invoice_contacts` to pull a roster of clients. After getting that list, you can use specific contact details to fetch all necessary product listings using `list_invoice_items`. This ensures your billing is always based on the most current service catalog.

Generating and Reviewing Billing Docs

The process runs like this: first, you might call `get_invoice_details` to check an existing invoice number. If everything looks good, your agent moves on to calling `create_new_invoice`. The full execution path—from checking details to creating the final document—is tracked and observable via LangSmith.

Setup guide

Set up Zoho Invoice 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 Zoho Invoice 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({
    "zoho-invoice-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 Zoho Invoice transactions"
    })
    print(result["messages"][-1].content)
