What this MCP does

Aggregates developer-community activity into frequently refreshed trend signals, entity rankings, evidence, and historical momentum scores.

get_entity
Get entity detail
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.
Input schema
{'type': 'object', 'required': ['name'], 'properties': {'name': {'type': 'string', 'description': 'Entity name as returned by list_entities, e.g. "kubernetes".'}}, 'additionalProperties': False}
get_topic
Get topic detail
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.
Input schema
{'type': 'object', 'required': ['id'], 'properties': {'id': {'type': 'string', 'description': 'Topic id as returned by list_signals, e.g. "hn:48910545".'}}, 'additionalProperties': False}
list_entities
List trending 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.
Input schema
{'type': 'object', 'required': [], 'properties': {'limit': {'type': 'integer', 'maximum': 200, 'minimum': 1, 'description': 'How many entities to return (default 50, max 200).'}, 'category': {'enum': ['ai', 'devtools', 'security', 'web', 'data', 'crypto', 'hardware', 'business', 'science', 'other'], 'type': 'string', 'description': 'Restrict to one category. Omit for all categories.'}}, 'additionalProperties': False}
list_signals
List live 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.
Input schema
{'type': 'object', 'required': [], 'properties': {'limit': {'type': 'integer', 'maximum': 200, 'minimum': 1, 'description': 'How many signals to return (default 50, max 200).'}, 'category': {'enum': ['ai', 'devtools', 'security', 'web', 'data', 'crypto', 'hardware', 'business', 'science', 'other'], 'type': 'string', 'description': 'Restrict to one category. Omit for all categories.'}}, 'additionalProperties': False}
