How to Use the GDACS MCP in LangChain

Q: How do I connect the GDACS MCP Server to my LangChain agent?

Install langchain-mcp-adapters and initialize the server using the MCP adapter with your Vinkius endpoint. From there, call client.gettools() and pass the returned tools directly to your agent constructor.

Q: Can my LangChain chain filter GDACS alerts by severity?

Yes. You use getalerts and pass parameters to filter by color codes like red, orange, or green. Your agent reads these parameters to decide whether to halt a chain or proceed with deeper analysis.

Q: How does LangChain handle the complex GeoJSON data from GDACS?

The geteventgeojson tool returns standard geographic boundaries directly to your LangChain run. You can pipe this JSON payload straight into vector databases or spatial analysis tools within your chain.

Feed real-time global disaster telemetry directly into your LangChain reasoning chains to automate risk analysis.

Chaining GDACS Alert Telemetry in LangChain

The GDACS MCP Server exposes tools like `get_alerts` and `get_event_list` to pull real-time hazard data directly into your agent chains. Your agent runs these tools, filters by event type or time period, and immediately feeds the outputs into downstream analysis steps. There are no manual APIs to configure. By linking these calls, your agent can detect an active event and instantly trigger detailed lookups. It pipes the general alert data into specific queries to build a complete situational profile without human intervention.

Geospatial Mapping and Impact Assessment

The `get_event_geojson` tool retrieves spatial boundaries and population exposure polygons for active disaster zones. Your LangChain agent passes these coordinates to your mapping services to overlay risk zones against your physical assets. Combine this spatial data with `get_impacts` to query modeled fatalities, affected populations, and economic loss estimates. This turns raw coordinates into concrete risk scores that your workflow can act on immediately.

Real-Time Climate and Geological Tracking

Specific hazard tools like `get_latest_earthquakes` and `get_latest_floods` deliver instant telemetry on active global events. Your agent monitors these feeds continuously, checking parameters like magnitude, depth, and flood severity estimates. The server also provides `get_latest_cyclones`, `get_latest_droughts`, `get_latest_volcanoes`, and `get_latest_wildfires` to cover all major hazard categories. This allows your chains to process diverse environmental threats using a single, unified interface.

Setup guide

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

The `get_event_geojson` tool returns standard geographic boundaries directly to your LangChain run. You can pipe this JSON payload straight into vector databases or spatial analysis tools within your chain.

You track six major disaster types. The server includes dedicated tools like `get_latest_wildfires`, `get_latest_volcanoes`, and `get_latest_cyclones` to monitor active events worldwide.

Vinkius runs this MCP server in an isolated sandbox, meaning your queries for disaster telemetry and coordinates never leak. The server only fetches public disaster alerts and impact data, keeping your asset locations and internal queries completely private.
