Execute Complex Visitor Workflows via MCP Server

You can chain actions together, making the agent decide which tool to call next. For instance, you might first use `list_locations` to find an ID, then pass that ID into a call to `create_invite`. This allows for complex, multi-step reasoning where one tool's output directly feeds another. This capability means your agent doesn't just run single commands. It builds a true workflow: get the location details via `get_location`, verify it's correct, and then use that confirmed data to schedule the appointment with `create_group_visit`. The result is reliable automation.

Manage Hosts and Groups in LangChain

Managing employee access requires multiple steps. You can first check who's available using `list_hosts` to ensure the host exists. Then, you use that confirmed list of hosts when running `create_hosts_batch` for onboarding new staff. For group events, you might need to update details after scheduling them. Use `get_group_visit` to pull existing data; then, if the count changed, call `update_group_visit`. The entire process flows logically through your LangChain agent.

Maintain Security and Audit Trails with MCP Server

Compliance reporting needs historical accuracy. You can pull records using `list_audit_logs` to track every action taken within the system. If you're investigating a specific incident, you might cross-reference an audit log entry ID against a detailed record from `get_signin`. This structured data access is critical for security reviews. You don't just see a status; you get verifiable historical facts about who checked in and when.

Setup guide

Set up Traction Guest 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 Traction Guest 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({
    "traction-guest-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 Traction Guest transactions"
    })
    print(result["messages"][-1].content)
