Using Item IDs to Retrieve Specific Content
Understanding Item IDs
Every piece of content on Hacker News—whether it's a story, comment, poll, or job posting—has a unique numeric identifier called an Item ID. These IDs are the foundation for retrieving specific content through the MCP server, allowing you to access exact posts, comments, or discussions without searching through lists or feeds.
Why Use Item IDs?
Item IDs provide direct access to Hacker News content with precision and efficiency. When you need to reference a specific discussion, retrieve a particular comment thread, or share exact content with others, Item IDs ensure you're accessing the correct information every time. They're especially valuable when following up on previously discovered content or when someone shares a specific Hacker News item you want to analyze.
Finding Item IDs
Item IDs appear in several places throughout Hacker News. The most common source is the URL of any Hacker News page—for example, https://news.ycombinator.com/item?id=12345678 contains the Item ID 12345678.
When you retrieve stories through feeds like "top stories" or "new stories," the server returns Item IDs as part of the response data. These IDs can then be used for follow-up queries to get detailed information about specific items or their comment threads.
Retrieving Content by Item ID
To access specific content using an Item ID, simply request the item through your AI assistant. You might say something like "Get details for Hacker News item 12345678" or "Show me the comments on item 12345678." The server will retrieve the complete data for that item, including its title, content, author, score, timestamp, and associated metadata.
For stories, you'll receive the submission details along with basic information about the discussion. For comments, you'll get the comment text, author, timestamp, and relationships to parent comments or child replies.
Working with Comment Threads
Comment threads are particularly useful when accessed via Item IDs. Each comment has its own unique ID, allowing you to start reading from any point in a discussion tree. This is valuable for deep-diving into specific sub-conversations or sharing particularly insightful commentary with others. When you retrieve a comment by its ID, you can also navigate to its parent comments or child replies using their respective Item IDs.
Best Practices
Keep track of Item IDs for content you reference frequently or plan to revisit. Since IDs are permanent and never change, they serve as reliable bookmarks for important discussions or valuable resources. When collaborating with others or documenting research, including Item IDs ensures everyone can access the exact same content you're referencing.
