Perplexity

Orchestrate complex contact journeys

You can chain together multiple steps to manage contacts. First, use `search_contacts` to find a user by criteria; then, pass the resulting ID into `get_contact` for full details. This allows your agent to build a complete profile before taking action. This chaining ability means you don't just look up data—you act on it immediately. You can follow up by using `add_contact` to ensure they are properly listed, setting up the perfect next step in your automation pipeline.

Automate campaigns and content delivery

Want an agent that runs a whole campaign? Start by listing available options with `list_email_lists` to determine where to send messages. Next, you can use the gathered list ID to execute a specific action via `trigger_workflow`. The output of the initial list call directly feeds into the subsequent workflow trigger. Furthermore, your chain doesn't stop at email. You can follow up by using `create_social_post` with content generated in an earlier step, making the entire marketing process run through a single, observable agent sequence.

Process orders and build customer records

When a purchase happens, you can immediately log it by calling `add_ecommerce_order`. This action provides the necessary transaction details for your chain to continue. The order data can then be combined with contact information. After logging the sale, you'll need to update the customer record. You can use `get_contact` or even `search_contacts` using identifiers pulled from the e-commerce order tool call. This ensures your agent has a single source of truth for every interaction.

Setup guide

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

Common questions about VBOUT MCP in LangChain

The MCP Server provides tools that act as callable functions within your chain. Your agent decides which tool to call and in what sequence based on the data it receives from prior steps. It's pure, observable reasoning.

VBOUT handles various marketing data types, including contact details, e-commerce order records, and social media content drafts. Your agent can interact with all these domains.

Absolutely. The power of the framework is that every tool call—like `list_campaigns` followed by `trigger_workflow`—is treated as an explicit link in your reasoning chain.

Yes. While stateless by default, you can use the client's session method to maintain a persistent context across multiple tool calls within a single workflow run.

You should start with `search_contacts` to narrow down the user pool. Then, pass the specific ID found into `get_contact`. This two-step process ensures you get accurate and detailed records.
