How to Use the Newslit MCP in LangChain

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

Install langchain-mcp-adapters and use the MultiServerMCPClient to connect to the Vinkius endpoint. This client handles the connection and registers the tools directly into your agent environment.

Q: Can LangChain agents manage Newslit reports autonomously?

Yes, your agent decides when to call createreport or updatereport based on your instructions. It analyzes incoming text and updates your tracker parameters dynamically.

Q: Can I combine Newslit with other tools in a single chain?

You can. LangChain lets you link the output of liststories to a vector store or email tool to alert your team about critical press hits.

Build LangChain pipelines that track media coverage and trigger PR actions automatically when news drops.

Multi-step media tracking with LangChain agents

The `list_stories` tool lets you feed live news directly into your next chain step to filter out noise based on custom criteria. You don't have to spend hours manually copying headlines into spreadsheets anymore. Your agent uses `create_report` to spin up a new tracker when a PR crisis hits. It then updates the parameters using `update_report` as the situation evolves, all tracked inside LangSmith.

Trace Newslit MCP Server actions in LangSmith

Monitoring your media reports starts with the `list_reports` tool, which logs every call with full visibility inside your tracing suite. You see exactly what parameters your agent sends to `get_report` during a run. Debugging broken runs takes seconds because you see the raw JSON payload. If `delete_report` fails, LangSmith flags the exact token count and response code.

Chain media intelligence with external databases

The `list_stories` tool connects your news coverage to your CRM or SQL database using LangChain's 500+ integrations. Your agent uses the MCP Server to fetch coverage and update internal records in one go. When new press opportunities appear, the agent runs `create_report` to isolate that specific coverage. You get a clean, automated pipeline that links public news to internal contacts.

Setup guide

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