How to Use the NeetoInvoice MCP in LangChain

Q: How do I connect NeetoInvoice to my LangChain agent?

Install the langchain-mcp-adapters package and initialize the client with your Vinkius endpoint. Pass the tools directly to your agent executor to start running billing workflows.

Q: Can LangChain run multi-step invoicing with NeetoInvoice?

Yes. Your agent can call listtimeentries to gather outstanding hours, calculate totals, and then execute generateinvoice in a single run.

Q: How does LangChain handle errors when updating a NeetoInvoice client?

The agent receives structured error payloads from updateclient or updaterecipient tool calls. You can design your chain to catch these errors and retry or notify a PM.

Run multi-step billing and project workflows in LangChain using direct tool execution.

Perplexity

Direct client onboarding via LangChain

The `create_client` tool registers a new client with their name, currency, and status directly inside your execution chain. Your agent can immediately follow up by calling `create_recipient` to add primary billing contacts without needing human intervention. This MCP setup allows LangChain to pass outputs from previous steps straight into client profiles. You get clean, structured data entry without writing custom API glue code.

Automated time tracking and invoicing chains

The `create_time_entry` tool logs billable hours directly from developer slack updates or git commits in your chain. Once logs are in, your agent calls `list_time_entries` to verify the hours before triggering `generate_invoice` to bill the client. By linking these tools, your LangChain pipeline handles the entire billing lifecycle step-by-step. LangSmith traces every tool call so you can audit the inputs and outputs of each run.

Dynamic team and project syncs

The `create_project` tool sets up new workspaces while `add_project_user` assigns team members based on project requirements. Your agent can query `list_team_members` to see who is available in the workspace before making assignments. This MCP Server keeps your project structures aligned with your real-world team rosters. It removes the manual overhead of managing user access across multiple client accounts.

Setup guide

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