This guide uses Atomic Agent's built-in Composio integration. You need Atomic Agent v0.5.6 or later, your own Composio API key, and a Hackernews account. See the [Atomic Agent documentation](https://atomicagent.io/docs/?cta_placement=atomic-agent-docs) for installation instructions. ## Also integrate Hackernews with - [OpenAI Agents SDK](https://composio.dev/toolkits/hackernews/framework/open-ai-agents-sdk) - [Claude Agent SDK](https://composio.dev/toolkits/hackernews/framework/claude-agents-sdk) - [Claude Code](https://composio.dev/toolkits/hackernews/framework/claude-code) - [Claude Cowork](https://composio.dev/toolkits/hackernews/framework/claude-cowork) - [Codex](https://composio.dev/toolkits/hackernews/framework/codex) - [OpenClaw](https://composio.dev/toolkits/hackernews/framework/openclaw) - [Hermes](https://composio.dev/toolkits/hackernews/framework/hermes-agent) - [Google ADK](https://composio.dev/toolkits/hackernews/framework/google-adk) - [LangChain](https://composio.dev/toolkits/hackernews/framework/langchain) - [Vercel AI SDK](https://composio.dev/toolkits/hackernews/framework/ai-sdk) - [Mastra AI](https://composio.dev/toolkits/hackernews/framework/mastra-ai) - [LlamaIndex](https://composio.dev/toolkits/hackernews/framework/llama-index) - [CrewAI](https://composio.dev/toolkits/hackernews/framework/crew-ai) - [Pydantic AI](https://composio.dev/toolkits/hackernews/framework/pydantic-ai) - [AutoGen](https://composio.dev/toolkits/hackernews/framework/autogen) ## TL;DR ### How Atomic Agent connects to Hackernews Atomic Agent connects to Composio's Tool Router over Streamable HTTP MCP. It discovers the tools needed for your request, and Composio handles account authentication. Execution and account-connection tools follow Atomic Agent's configured approval policy. Review any approval prompt before allowing an action on your connected account. ## Connect Hackernews to Atomic Agent ### Connect Hackernews to Atomic Agent - Sign up or sign in to the [Composio dashboard](https://dashboard.composio.dev/?cta_placement=atomic-agent-api-key). Copy your API key. - In Atomic Agent, open the Integrations tab and select Composio. Select API key, press e, paste the key, and press Enter. The tools become available immediately, without a restart. - Ask Atomic Agent to do something in Hackernews. It searches Composio for the right tool. - On first use, open the sign-in link returned in the chat. Connect your Hackernews account, then return to Atomic Agent to continue. ### Headless setup Add the following line to ~/.atomic-agent/.env, replacing YOUR_COMPOSIO_API_KEY with your key. Start Atomic Agent after saving the file. ```bash COMPOSIO_API_KEY=YOUR_COMPOSIO_API_KEY ``` ## What is the Hackernews MCP server, and what's possible with it? The Hackernews MCP server is an implementation of the Model Context Protocol that connects your AI agent and assistants like Claude, Cursor, etc directly to the Hacker News platform. It provides structured and secure access to top tech stories, user profiles, and community discussions, so your agent can fetch trending posts, search for news, analyze user activity, and surface the latest updates on your behalf. - Frontpage highlights and trending tech stories: Instantly get the current frontpage posts so your agent can summarize or monitor what's hot in tech right now. - Smart post search and discovery: Search Hacker News posts by keyword, filter results, and explore relevant discussions tailored to your interests. - Real-time updates on new posts: Let your agent fetch the latest or today's posts, keeping you in the loop on breaking news and emerging trends. - In-depth post and comment analysis: Retrieve detailed information about any specific Hacker News item, including stories and comment threads, for deeper insights. - User profile lookup and insights: Access details about any Hacker News user, helping you analyze activity, contributions, or community reputation. ## Supported Tools | Tool slug | Name | Description | |---|---|---| | `HACKERNEWS_GET_ASK_STORIES` | Get Ask HN Story IDs | Get up to 200 latest Ask HN story IDs from Hacker News.

Copy the key directly from the Composio dashboard. Atomic Agent requires ASCII characters because it sends the key in an HTTP header. Remove any extra characters introduced when copying. ### Why are Composio tools unavailable after saving a key? Check that you use Atomic Agent v0.5.6 or later and that Composio is enabled in your configuration. A "composio": { "enabled": false } setting disables the integration while keeping the saved key on disk. ### Does Composio have a free plan? The Hobby plan includes 100,000 tool calls per month. Composio-managed OAuth apps have a lower included allowance. See [Composio pricing](/pricing) for the current limits that apply to your connection. ## Complete Code None listed. ## Conclusion ### Use Hackernews from Atomic Agent With your account connected, ask Atomic Agent to work with Hackernews in natural language. You can connect more apps through the same Composio integration as you need them.

With a standalone Hackernews MCP server, the agents and LLMs can only access a fixed set of Hackernews tools tied to that server. However, with the Composio Tool Router, agents can dynamically load tools from Hackernews and many other apps based on the task at hand, all through a single MCP endpoint. ### Can I use Tool Router MCP with Atomic Agent? Yes, you can. Atomic Agent 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 Hackernews tools. ### Can I manage the permissions and scopes for Hackernews while using Tool Router? Yes, absolutely. You can configure which Hackernews 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 Hackernews data and credentials are handled as safely as possible. --- [See all toolkits](https://composio.dev/toolkits) ยท [Composio docs](https://docs.composio.dev/llms.txt)
