Chain Paycove tools in LangChain pipelines

Feed the output of `list_overdue_invoices` directly into a processing chain to trigger payment reminders. Your agent reads the status, evaluates the data, and decides whether to escalate. This MCP Server allows LangChain agents to handle complex logic without manual input. You define the sequence once and let the chain handle the execution across your CRM.

Observe Paycove tool execution in LangSmith

Track every tool call from `create_invoice` to `get_quote` with full observability. You see exactly how the agent reached its conclusion through detailed trace logs. Debugging becomes a matter of inspecting the chain history. You’ll catch logic errors in your automation before they impact your billing cycle.

Combine Paycove data with external APIs

Link Paycove operations with databases or external services within a single agentic workflow. Use `list_clients` to pull account details before running a custom risk assessment tool. Your agent manages state across these calls, ensuring the data flows correctly between systems. It’s about building a cohesive pipeline rather than manual scripts.

Setup guide

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