AI-Powered Hacker News Insights with Custom Tools
detail.loadingPreview
Leverage the power of AI to instantly query Hacker News for top posts. This workflow demonstrates how to create a custom tool for your AI agent, enabling it to fetch and analyze data from Hacker News in real-time.
About This Workflow
This n8n workflow showcases a sophisticated integration of AI with a custom data source. At its core, an AI agent, powered by an OpenAI Chat Model, is equipped with a custom tool designed to interact with Hacker News. This tool, named 'hn_tool', is built upon a sub-workflow that specifically fetches the top 50 posts from Hacker News. The main workflow orchestrates the agent's ability to understand natural language queries, such as 'What is the 5th most popular post ever on Hacker News?', and then delegate the data retrieval to the custom tool. The fetched data is processed, cleaned, and then formatted into a JSON string for the agent to use in its response.
This workflow highlights the flexibility of n8n in creating custom AI capabilities by defining specialized tools that can be invoked by AI agents, opening up a world of possibilities for intelligent data analysis and retrieval.
Key Features

How To Use
- Set up your OpenAI credentials: Ensure your OpenAI API key is configured in n8n under credentials.
- Configure the 'When chat message received' node: This node acts as the trigger for your AI agent. It will receive incoming chat messages.
- Connect the 'AI Agent' node: Link the chat trigger to the AI Agent node. This node will process the incoming message and determine how to respond.
- Define your Custom Tool: In the 'Custom tool to call the wf below1' node, configure the
name(e.g.,hn_tool) anddescriptionof your tool. This description is crucial for the AI agent to understand when to use this tool. - Build the Sub-workflow: Create a separate workflow (or use the current one as a sub-workflow) that fetches data from Hacker News (using the 'Hacker News' node). Ensure this sub-workflow is designed to be executed by another workflow.
- Process and Output Data: Use nodes like 'Clean up data' and 'Stringify' within the sub-workflow to prepare the Hacker News data into a format that the AI agent can understand.
- Connect the Sub-workflow to the Tool: In the 'Custom tool to call the wf below1' node, specify the
workflowIdof the sub-workflow that fetches Hacker News data. - Test your workflow: Click the 'Chat' button in the n8n interface and enter a query like 'What is the 5th most popular post ever on Hacker News?' to see your AI agent in action.
