Automating Lead Qualification Chains

You can build multi-step logic where the agent first calls `get_lead` to gather current data. Then, it uses that output to call `check_skylink_status` before deciding if a follow-up task is needed via `create_task`. LangChain handles this full sequence, letting you trace exactly which tool was called and why in the chain.

Managing Deals Through Structured Steps

Need to move a deal forward? The agent can first run `get_deal` for existing info. Next, it uses that detail to call `update_deal` with new status data. This chain ensures every action is logged and traceable through LangSmith, making the entire process observable.

Comprehensive Contact Management

Creating or updating contacts becomes a reliable workflow. Start by calling `get_contact` to see if they exist. If not, you trigger `create_contact`, and then immediately follow up with `list_contacts` to confirm the record. This guarantees data consistency across multiple steps in your agent's reasoning flow.

Setup guide

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