How to Use the WorldNewsAPI MCP in LangChain

Q: Can WorldNewsAPI's top headlines be used in a multi-step LangChain process?

Absolutely. An agent can get top news using gettopworldnews, then use the titles found as keywords for a follow-up, more detailed search via searchworldnews.

Q: What is the best way to audit an article's source data with WorldNewsAPI and LangChain?

You can run this in two steps. First, use extractnewsfromurl to get content from a specific link. Then, you might verify that information by running a targeted search using searchworldnews.

Q: If the WorldNewsAPI is down, how does LangChain handle it?

You can build a robust chain starting with checkapistatus. If the status check fails, your agent stops and reports an outage instead of failing on resource calls like gettopworldnews.

Build complex news pipelines with LangChain, letting your agents decide how to use WorldNewsAPI.

Multi-Step News Auditing

The `search_world_news` tool lets your agent find initial articles using keywords. Then, the agent can pass a resulting URL to `extract_news_from_url` to pull out full text and metadata. This chained process builds a complete audit trail of news items. Your ReAct agent decides which step comes next. It uses the output from one tool—say, a list of top headlines from `get_top_world_news`—as the context for searching more deeply with `search_world_news`.

Determining News Source Validity

You can use `check_api_status` right at the start of a chain to make sure the WorldNews service is up. If it fails, your agent skips resource-heavy steps like searching and tells the user immediately. This prevents wasted calls. The agent manages this flow logic. It decides if the initial search needs refinement or if the gathered top news from `get_top_world_news` is sufficient to answer the prompt.

Targeted News Aggregation

Start by getting high-level overviews with `get_top_world_news` for a specific country and language. Next, if you need deeper context on one story, your agent can grab the URL and use `extract_news_from_url`. You get both the broad picture and granular data points. This flow lets the agent assemble complex answers: 'The top stories show X (via `get_top_world_news`), and this article confirms Y (via `extract_news_from_url`).'

Setup guide

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