Understanding Data Retrieval Patterns

When working with the Hacker News MCP server, efficient data retrieval begins with understanding what information you actually need. Rather than making broad requests that return large amounts of data, focus your queries on specific items, story types, or user profiles. For example, instead of asking for "everything about Hacker News," request "top 10 stories" or "comments on story ID 12345." This targeted approach reduces processing time and delivers more relevant results.

Start with Story Lists, Then Drill Down

The most efficient workflow follows a hierarchical pattern. Begin by retrieving story lists (top, new, or best stories) to get an overview of current content. These lists return basic metadata including story IDs, titles, and scores. Once you identify stories of interest, make follow-up requests for detailed information about specific items, including full comment threads or author profiles. This two-step approach minimizes unnecessary data transfer while ensuring you capture all relevant details.

Leverage Item IDs for Direct Access

Every story, comment, and user on Hacker News has a unique identifier. When you know the specific ID of an item you need, use it directly rather than searching through lists. Direct ID-based retrieval is the fastest method available and should be your preferred approach whenever possible. Save relevant IDs from previous queries to enable quick access to stories or comment threads you may want to revisit.

Be Mindful of Comment Thread Depth

Comment threads on popular stories can be extensive, with hundreds of nested replies. When retrieving comments, consider whether you need the entire thread or just top-level responses. Deep comment trees require multiple API calls to fully traverse, so limit your scope to what's necessary for your use case. If you're analyzing community sentiment, top comments often provide sufficient insight without requiring complete thread retrieval.

Cache Results Appropriately

While the server provides real-time access to Hacker News data, not all information changes frequently. User profiles, older stories, and established comment threads remain relatively static. When working with historical data or conducting analysis over time, cache results locally to avoid redundant requests. However, keep cache durations reasonable—story scores and comment counts can change as community engagement continues.

Batch Related Requests

When you need information about multiple items, structure your queries to retrieve related data efficiently. Instead of making separate requests for each story in a discussion about a particular topic, identify all relevant story IDs first, then retrieve them in a logical sequence that minimizes back-and-forth communication with the server.
