Pydantic AI is a Python framework for building AI agents with strong typing and validation. It leverages Pydantic's data validation capabilities to create robust, type-safe AI applications. Key features include: - Type Safety: Built on Pydantic for automatic data validation - MCP Support: Native support for Model Context Protocol servers - Streaming: Built-in support for streaming responses - Async First: Designed for async/await patterns ## 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. | ## Supported Triggers None listed. ## 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 Before starting, make sure you have: - Python 3.9 or higher - A Composio account with an active API key - Basic familiarity with Python and async programming ### 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 Install the required libraries. What's happening: - composio connects your agent to external SaaS tools like News api - pydantic-ai lets you create structured AI agents with tool support - python-dotenv loads your environment variables securely from a .env file ```bash pip install composio pydantic-ai python-dotenv ``` ### 3. Set up environment variables Create a .env file in your project root. What's happening: - COMPOSIO_API_KEY authenticates your agent to Composio's API - USER_ID associates your session with your account for secure tool access - OPENAI_API_KEY to access OpenAI LLMs ```bash COMPOSIO_API_KEY=your_composio_api_key_here USER_ID=your_user_id_here OPENAI_API_KEY=your_openai_api_key ``` ### 4. Import dependencies What's happening: - We load environment variables and import required modules - Composio manages connections to News api - MCPServerStreamableHTTP connects to the News api MCP server endpoint - Agent from Pydantic AI lets you define and run the AI assistant ```python import asyncio import os from dotenv import load_dotenv from composio import Composio from pydantic_ai import Agent from pydantic_ai.mcp import MCPServerStreamableHTTP load_dotenv() ``` ### 5. 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 ```python async def main(): api_key = os.getenv("COMPOSIO_API_KEY") user_id = os.getenv("USER_ID") if not api_key or not user_id: raise RuntimeError("Set COMPOSIO_API_KEY and USER_ID in your environment") # Create a Composio Tool Router session for News api composio = Composio(api_key=api_key) session = composio.create( user_id=user_id, toolkits=["news_api"], ) url = session.mcp.url if not url: raise ValueError("Composio session did not return an MCP URL") ``` ### 6. Initialize the Pydantic AI Agent What's happening: - The MCP client connects to the News api endpoint - The agent uses GPT-5 to interpret user commands and perform News api operations - The instructions field defines the agent's role and behavior ```python # Attach the MCP server to a Pydantic AI Agent news_api_mcp = MCPServerStreamableHTTP(url, headers={"x-api-key": COMPOSIO_API_KEY}) agent = Agent( "openai:gpt-5", toolsets=[news_api_mcp], instructions=( "You are a News api assistant. Use News api tools to help users " "with their requests. Ask clarifying questions when needed." ), ) ``` ### 7. Build the chat interface What's happening: - The agent reads input from the terminal and streams its response - News api API calls happen automatically under the hood - The model keeps conversation history to maintain context across turns ```python # Simple REPL with message history history = [] print("Chat started! Type 'exit' or 'quit' to end.\n") print("Try asking the agent to help you with News api.\n") while True: user_input = input("You: ").strip() if user_input.lower() in {"exit", "quit", "bye"}: print("\nGoodbye!") break if not user_input: continue print("\nAgent is thinking...\n", flush=True) async with agent.run_stream(user_input, message_history=history) as stream_result: collected_text = "" async for chunk in stream_result.stream_output(): text_piece = None if isinstance(chunk, str): text_piece = chunk elif hasattr(chunk, "delta") and isinstance(chunk.delta, str): text_piece = chunk.delta elif hasattr(chunk, "text"): text_piece = chunk.text if text_piece: collected_text += text_piece result = stream_result print(f"Agent: {collected_text}\n") history = result.all_messages() ``` ### 8. Run the application What's happening: - The asyncio loop launches the agent and keeps it running until you exit ```python if __name__ == "__main__": asyncio.run(main()) ``` ## Complete Code ```python import asyncio import os from dotenv import load_dotenv from composio import Composio from pydantic_ai import Agent from pydantic_ai.mcp import MCPServerStreamableHTTP load_dotenv() async def main(): api_key = os.getenv("COMPOSIO_API_KEY") user_id = os.getenv("USER_ID") if not api_key or not user_id: raise RuntimeError("Set COMPOSIO_API_KEY and USER_ID in your environment") # Create a Composio Tool Router session for News api composio = Composio(api_key=api_key) session = composio.create( user_id=user_id, toolkits=["news_api"], ) url = session.mcp.url if not url: raise ValueError("Composio session did not return an MCP URL") # Attach the MCP server to a Pydantic AI Agent news_api_mcp = MCPServerStreamableHTTP(url, headers={"x-api-key": COMPOSIO_API_KEY}) agent = Agent( "openai:gpt-5", toolsets=[news_api_mcp], instructions=( "You are a News api assistant. Use News api tools to help users " "with their requests. Ask clarifying questions when needed." ), ) # Simple REPL with message history history = [] print("Chat started! Type 'exit' or 'quit' to end.\n") print("Try asking the agent to help you with News api.\n") while True: user_input = input("You: ").strip() if user_input.lower() in {"exit", "quit", "bye"}: print("\nGoodbye!") break if not user_input: continue print("\nAgent is thinking...\n", flush=True) async with agent.run_stream(user_input, message_history=history) as stream_result: collected_text = "" async for chunk in stream_result.stream_output(): text_piece = None if isinstance(chunk, str): text_piece = chunk elif hasattr(chunk, "delta") and isinstance(chunk.delta, str): text_piece = chunk.delta elif hasattr(chunk, "text"): text_piece = chunk.text if text_piece: collected_text += text_piece result = stream_result print(f"Agent: {collected_text}\n") history = result.all_messages() if __name__ == "__main__": asyncio.run(main()) ``` ## Conclusion You've built a Pydantic AI agent that can interact with News api through Composio's Tool Router. With this setup, your agent can perform real News api actions through natural language. You can extend this further by: - Adding other toolkits like Gmail, HubSpot, or Salesforce - Building a web-based chat interface around this agent - Using multiple MCP endpoints to enable cross-app workflows (for example, Gmail + News api for workflow automation) This architecture makes your AI agent "agent-native", able to securely use APIs in a unified, composable way without custom integrations. ## How to build News api MCP Agent with another framework - [OpenAI Agents SDK](https://composio.dev/toolkits/news_api/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/news_api/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/news_api/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/news_api/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/news_api/framework/codex) - [OpenClaw](https://composio.dev/toolkits/news_api/framework/openclaw) - [Hermes](https://composio.dev/toolkits/news_api/framework/hermes-agent) - [CLI](https://composio.dev/toolkits/news_api/framework/cli) - [Google ADK](https://composio.dev/toolkits/news_api/framework/google-adk) - [LangChain](https://composio.dev/toolkits/news_api/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/news_api/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/news_api/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/news_api/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/news_api/framework/crew-ai) ## Related Toolkits - [Youtube](https://composio.dev/toolkits/youtube) - YouTube is a leading video-sharing platform for uploading, streaming, and discovering content.

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 Pydantic AI? Yes, you can. Pydantic AI 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. --- [See all toolkits](https://composio.dev/toolkits) · [Composio docs](https://docs.composio.dev/llms.txt)
