How to Use the AirLabs MCP in LangChain

Q: How do I connect the AirLabs MCP Server to LangChain?

Install the langchain-mcp-adapters package and register the Vinkius transport URL. Your LangChain agent then gets access to the tools list automatically.

Q: Can I trace AirLabs tool calls from LangChain in LangSmith?

Yes, every execution of tools like getflightinfo is tracked inside LangSmith. You see the exact inputs, outputs, and latency for every flight query.

Q: What happens if an airport code is incomplete?

The autocompleteairport tool resolves partial inputs into valid IATA codes. Your agent runs this lookup first before calling other airport-specific endpoints.

Feed real-time flight tracking and airport metrics directly into your LangChain reasoning loops.

Perplexity

Multi-step flight tracking chains

`get_flights` pulls active, real-time aircraft positions based on geographic boundaries or airline codes. Your LangChain agent receives this raw coordinate data and immediately feeds it into subsequent steps without manual glue code. You build chains where a change in aircraft altitude triggers a lookup via `get_aircraft` to inspect the airframe specifications. This setup lets your pipeline run complex aviation investigations autonomously.

Live airport delays in LangChain agents

`get_airport_delays` retrieves current arrival and departure delay metrics for any designated airport code. LangChain handles this tool output as a standard state variable, passing it straight to your decision-making nodes. If delays exceed your specified threshold, the agent automatically triggers `get_schedules` to find alternative routes. You get a self-healing travel routing agent that reacts to real-world airport performance.

LangChain MCP Server routing for fleets

`get_airline_fleet` exposes complete fleet data including registration numbers, aircraft models, and operational status to your LangChain application. This MCP Server integration allows you to query active airline profiles without spinning up custom API wrappers. Combining this fleet data with `get_airline_routes` reveals exactly how carriers deploy specific aircraft models across their networks. The entire process runs through Vinkius's secure sandboxed runtime, keeping your API keys hidden from the agent.

Setup guide

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

Yes, every execution of tools like `get_flight_info` is tracked inside LangSmith. You see the exact inputs, outputs, and latency for every flight query.

LangChain lets you pass these aviation tools alongside your database tools in the same agent constructor. The agent decides when to fetch flight data and when to write it to your database.

The `autocomplete_airport` tool resolves partial inputs into valid IATA codes. Your agent runs this lookup first before calling other airport-specific endpoints.

Every request for flight coordinates and airline fleets runs inside an isolated, ephemeral V8 container. Vinkius never stores your flight queries or API access tokens on disk.
