How to Use the Albacross MCP in LangChain

Q: How do I use LangChain to filter Albacross leads by industry?

Your agent should call listleads, then iterate through the results. For each lead, it calls getleaddetails and applies your filtering logic in Python based on the industry field.

Q: Can a LangChain agent identify a visitor from Albacross and then check if they're in a segment?

Yes, that's a classic chain. The agent calls identifycompanybyip, then passes the resulting company ID to getleaddetails to find which segments it belongs to.

Q: What's the best way to monitor Albacross API usage with LangChain?

Create a simple agent that calls getusagestats on a schedule. You can have it log the output or trigger an alert in another system if the usage exceeds a threshold.

Q: How are the Albacross tools exposed to my LangChain agent?

The langchain-mcp-adapters package handles it. You point it at the server URL, call client.gettools(), and LangChain gets a list of callable functions ready for your agent.

Connect LangChain to your Albacross account and build agents that turn anonymous traffic into qualified leads.

Automate Lead Qualification Chains

An agent can see a new website visitor, grab their IP, and immediately run `identify_company_by_ip`. With the company name, it then checks your defined target audiences using `list_segments`. This isn't a script; it's your agent deciding the next best action live. If there's a match, the chain continues. The agent calls `get_lead_details` to get the full picture and might check `list_workflows` to see how to route it. LangChain lets you build these multi-step sequences where the output of one Albacross tool becomes the input for the next.

Build Custom B2B Reporting Agents with this MCP Server

Go beyond simple dashboards. Build an agent that pulls all new companies from the last 24 hours with `list_leads`, then loops through each one using `get_lead_details`. Your agent can then aggregate the data to spot trends, like a sudden interest from a new industry. Have your agent monitor your API budget by calling `get_usage_stats` at the end of its run. This MCP server gives your agent the raw B2B data; LangChain gives it the power to connect that data to other tools, like a database or a Slack notification.

Dynamic Lead Enrichment Pipelines

Your agent can function as a central hub for enrichment. It takes a new lead—maybe from a form or another source—and uses Albacross to fill in the blanks. The agent uses `identify_company_by_ip` or looks up a domain, gets the firmographic data, and then passes that enriched record to your CRM. It’s a clean way to use your Albacross MCP connection to feed the rest of your marketing stack.

Setup guide

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