Server tool list (4)
Raw names from tools/list. Only developers need these.
| list_signals | Top technology signals ranked by momentum right now, scored every 30 minutes across ten developer and builder communities (Hacker News, GitHub, Stack Overflow, npm, Hugging Face, Dev.to, Lobsters, Product Hunt, arXiv, crypto governance forums). Call this to find what is gaining traction before it reaches search-trend tools — e.g. when the user asks what is emerging, trending, or worth paying attention to in a technology area. Returns live unredacted data with no delay. |
| get_topic | Full detail and complete score history for one topic, by id (e.g. "hn:48910545", "gh:1287845516"). Call this after list_signals to see how a specific signal has moved over time, its cross-source corroboration, and its lifecycle stage. Ids come from list_signals. |
| list_entities | Trending entities (products, companies, libraries, technologies) ranked by cross-source momentum. An entity aggregates every post, repo and release mentioning it across ten developer and builder communities — one row per trend rather than per post. Prefer this over list_signals when the user asks about trends or technologies; use list_signals for individual posts. |
| get_entity | Full detail for one entity by name (e.g. "kubernetes"): current composite score, complete score history, which communities are talking about it, and the live member items (evidence) behind the score. Names come from list_entities. |
