## Introduction

This guide walks you through connecting News api to LangChain using the Composio tool router. By the end, you'll have a working News api agent that can get headlines about today's tech news, find recent articles on climate change, show top stories from bbc news through natural language commands.
This guide will help you understand how to give your LangChain agent real control over a News api account through Composio's News api MCP server.
Before we dive in, let's take a quick look at the key ideas and tools involved.

## TL;DR

Here's what you'll learn:
- Get and set up your OpenAI and Composio API keys
- Connect your News api project to Composio
- Create a Tool Router MCP session for News api
- Initialize an MCP client and retrieve News api tools
- Build a LangChain agent that can interact with News api
- Set up an interactive chat interface for testing

## What is LangChain?

LangChain is a framework for developing applications powered by language models. It provides tools and abstractions for building agents that can reason, use tools, and maintain conversation context.
Key features include:
- Agent Framework: Build agents that can use tools and make decisions
- MCP Integration: Connect to external services through Model Context Protocol adapters
- Memory Management: Maintain conversation history across interactions
- Multi-Provider Support: Works with OpenAI, Anthropic, and other LLM providers

## What is the News api MCP server, and what's possible with it?

The News api MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to your News api account. It provides structured and secure access to live news data, so your agent can perform actions like searching headlines, retrieving articles, and filtering news stories by topic, source, or date on your behalf.
- Headline search and retrieval: Instantly fetch the latest news headlines from thousands of trusted sources around the world, tailored to your interests or keywords.
- Topic-based article discovery: Ask your agent to pull in-depth articles about specific topics, trends, or breaking events as they happen.
- Source and region filtering: Easily filter news stories by publication, language, or geographic region to get the most relevant updates for your needs.
- Date and time range queries: Quickly access news published within a certain date or time window, perfect for tracking ongoing stories or recent developments.
- Trending and popular news aggregation: Let your agent surface the most-read or widely shared articles so you never miss what’s making headlines.

## Supported Tools

| Tool slug | Name | Description |
|---|---|---|
| `NEWS_API_GET_EVERYTHING` | Get Everything | Tool to search through every article published by over 150,000 sources. At least one of q, sources, language, or domains must be set or the API returns a parametersMissing error. Historical date range depends on your News API plan tier (free plans limited to ~1 month). No country parameter exists; target geography via sources, domains, or country-specific terms in q. Burst requests may trigger HTTP 429; apply backoff on throttling errors. |
| `NEWS_API_GET_SOURCES` | Get Sources | Tool to fetch available news sources. Use when you need to retrieve a list of publishers by optional filters like category, language, or country. Source IDs returned here are the only valid IDs for filtering in NEWS_API_GET_EVERYTHING or NEWS_API_GET_TOP_HEADLINES — unrecognized IDs cause silently empty results. |
| `NEWS_API_GET_TOP_HEADLINES` | Get Top Headlines | Tool to retrieve live top and breaking headlines; does not support historical or date-bounded queries (use NEWS_API_GET_EVERYTHING for past date ranges). Results favor major outlets; use NEWS_API_GET_EVERYTHING or COMPOSIO_SEARCH_WEB for niche publications. Use when you need current headlines filtered by country, category, source(s), or keywords. |
| `NEWS_API_GET_V1_ARTICLES` | Get V1 Articles | Tool to fetch live article metadata from a news source using the legacy v1 API. Use when you need headlines from a specific source identifier. This v1 endpoint has been superseded by /v2/top-headlines. |

## Creating MCP Server - Stand-alone vs Composio SDK

The News api MCP server is an implementation of the Model Context Protocol that connects your AI agent to News api. It provides structured and secure access so your agent can perform News api operations on your behalf through a secure, permission-based interface.
With Composio's managed implementation, you don't have to create your own developer app. For production, if you're building an end product, we recommend using your own credentials. The managed server helps you prototype fast and go from 0-1 faster.

## Step-by-step Guide

### 1. Prerequisites

No description provided.

### 1. Getting API Keys for OpenAI and Composio

OpenAI API Key
- Go to the [OpenAI dashboard](https://platform.openai.com/settings/organization/api-keys) and create an API key. You'll need credits to use the models, or you can connect to another model provider.
- Keep the API key safe.
Composio API Key
- Log in to the [Composio dashboard](https://dashboard.composio.dev?utm_source=toolkits&utm_medium=framework_docs).
- Navigate to your API settings and generate a new API key.
- Store this key securely as you'll need it for authentication.

### 2. Install dependencies

No description provided.
```python
pip install composio-langchain langchain-mcp-adapters langchain python-dotenv
```

```typescript
npm install @composio/langchain @langchain/core @langchain/openai @langchain/mcp-adapters dotenv
```

### 3. Set up environment variables

Create a .env file in your project root.
What's happening:
- COMPOSIO_API_KEY authenticates your requests to Composio's API
- COMPOSIO_USER_ID identifies the user for session management
- OPENAI_API_KEY enables access to OpenAI's language models
```bash
COMPOSIO_API_KEY=your_composio_api_key_here
COMPOSIO_USER_ID=your_composio_user_id_here
OPENAI_API_KEY=your_openai_api_key_here
```

### 4. Import dependencies

No description provided.
```python
from langchain_mcp_adapters.client import MultiServerMCPClient
from langchain.agents import create_agent
from dotenv import load_dotenv
from composio import Composio
import asyncio
import os

load_dotenv()
```

```typescript
import { Composio } from '@composio/core';
import { LangchainProvider } from '@composio/langchain';
import { MultiServerMCPClient } from "@langchain/mcp-adapters";
import { createAgent } from "langchain";
import * as readline from 'readline';
import 'dotenv/config';

dotenv.config();
```

### 5. Initialize Composio client

What's happening:
- We're loading the COMPOSIO_API_KEY from environment variables and validating it exists
- Creating a Composio instance that will manage our connection to News api tools
- Validating that COMPOSIO_USER_ID is also set before proceeding
```python
async def main():
    composio = Composio(api_key=os.getenv("COMPOSIO_API_KEY"))

    if not os.getenv("COMPOSIO_API_KEY"):
        raise ValueError("COMPOSIO_API_KEY is not set")
    if not os.getenv("COMPOSIO_USER_ID"):
        raise ValueError("COMPOSIO_USER_ID is not set")
```

```typescript
const composioApiKey = process.env.COMPOSIO_API_KEY;
const userId = process.env.COMPOSIO_USER_ID;

if (!composioApiKey) throw new Error('COMPOSIO_API_KEY is not set');
if (!userId) throw new Error('COMPOSIO_USER_ID is not set');

async function main() {
    const composio = new Composio({
        apiKey: composioApiKey as string,
        provider: new LangchainProvider()
    });
```

### 6. Create a Tool Router session

What's happening:
- We're creating a Tool Router session that gives your agent access to News api tools
- The create method takes the user ID and specifies which toolkits should be available
- The returned session.mcp.url is the MCP server URL that your agent will use
- This approach allows the agent to dynamically load and use News api tools as needed
```python
# Create Tool Router session for News api
session = composio.create(
    user_id=os.getenv("COMPOSIO_USER_ID"),
    toolkits=['news_api']
)

url = session.mcp.url
```

```typescript
const session = await composio.create(
    userId as string,
    {
        toolkits: ['news_api']
    }
);

const url = session.mcp.url;
```

### 7. Configure the agent with the MCP URL

No description provided.
```python
client = MultiServerMCPClient({
    "news_api-agent": {
        "transport": "streamable_http",
        "url": session.mcp.url,
        "headers": {
            "x-api-key": os.getenv("COMPOSIO_API_KEY")
        }
    }
})

tools = await client.get_tools()

agent = create_agent("gpt-5", tools)
```

```typescript
const client = new MultiServerMCPClient({
    "news_api-agent": {
        transport: "http",
        url: url,
        headers: {
            "x-api-key": process.env.COMPOSIO_API_KEY
        }
    }
});

const tools = await client.getTools();

const agent = createAgent({ model: "gpt-5", tools });
```

### 8. Set up interactive chat interface

No description provided.
```python
conversation_history = []

print("Chat started! Type 'exit' or 'quit' to end the conversation.\n")
print("Ask any News api related question or task to the agent.\n")

while True:
    user_input = input("You: ").strip()

    if user_input.lower() in ['exit', 'quit', 'bye']:
        print("\nGoodbye!")
        break

    if not user_input:
        continue

    conversation_history.append({"role": "user", "content": user_input})
    print("\nAgent is thinking...\n")

    response = await agent.ainvoke({"messages": conversation_history})
    conversation_history = response['messages']
    final_response = response['messages'][-1].content
    print(f"Agent: {final_response}\n")
```

```typescript
let conversationHistory: any[] = [];

console.log("Chat started! Type 'exit' or 'quit' to end the conversation.\n");
console.log("Ask any News api related question or task to the agent.\n");

const rl = readline.createInterface({
    input: process.stdin,
    output: process.stdout,
    prompt: 'You: '
});

rl.prompt();

rl.on('line', async (userInput: string) => {
    const trimmedInput = userInput.trim();

    if (['exit', 'quit', 'bye'].includes(trimmedInput.toLowerCase())) {
        console.log("\nGoodbye!");
        rl.close();
        process.exit(0);
    }

    if (!trimmedInput) {
        rl.prompt();
        return;
    }

    conversationHistory.push({ role: "user", content: trimmedInput });
    console.log("\nAgent is thinking...\n");

    const response = await agent.invoke({ messages: conversationHistory });
    conversationHistory = response.messages;

    const finalResponse = response.messages[response.messages.length - 1]?.content;
    console.log(`Agent: ${finalResponse}\n`);
        
        rl.prompt();
    });

    rl.on('close', () => {
        console.log('\n👋 Session ended.');
        process.exit(0);
    });
```

### 9. Run the application

No description provided.
```python
if __name__ == "__main__":
    asyncio.run(main())
```

```typescript
main().catch((err) => {
    console.error('Fatal error:', err);

## Frequently Asked Questions

### What are the differences in Tool Router MCP and News api MCP?

With a standalone News api MCP server, the agents and LLMs can only access a fixed set of News api tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from News api and many other apps based on the task at hand, all through a single MCP endpoint.

### Can I use Tool Router MCP with LangChain?

Yes, you can. LangChain fully supports MCP integration. You get structured tool calling, message history handling, and model orchestration while Tool Router takes care of discovering and serving the right News api tools.

### Can I manage the permissions and scopes for News api while using Tool Router?

Yes, absolutely. You can configure which News api scopes and actions are allowed when connecting your account to Composio. You can also bring your own OAuth credentials or API configuration so you keep full control over what the agent can do.

### How safe is my data with Composio Tool Router?

All sensitive data such as tokens, keys, and configuration is fully encrypted at rest and in transit. Composio is SOC 2 Type 2 compliant and follows strict security practices so your News api data and credentials are handled as safely as possible.
