What it does
Upstar is an MCP server, a connector that lets an AI assistant use it as a tool. It is hosted: an assistant connects to it over the internet, nothing to install.
No capability identified yet from its description.
Facts come from the Official MCP Registry, as declared by the publisher. Capabilities are matched automatically (low confidence). None of this is a test of the tool.

9 tools offered to AI assistants
emerging· Small GitHub repositories (under 1,000 stars a week ago, at least 30 days old) gaining stars at least twice as fast as in a usual week, by that ratio; optionally in one topic.get_collection· A collection's ranking (score = momentum and health with the collection's weights) and its rising newcomers under 90 days old.get_repo· One GitHub repository as Upstar sees it, the same facts as its Upstar page: stars and gains, its usual week, its star total week by week over 12 weeks, its topics and ranks, when Upstar spotted it, its latest release, license, activity andlist_collections· Upstar's collections: open-source tools that do one job, or alternatives to one product, each ranked by momentum and health. Use a slug with get_collection.list_topics· Lists the topics Upstar ranks GitHub repositories in (emulation, self-hosted, Rust, MCP…): slug, name, category, description and how many repositories rank in each this week. Use a slug with topic_ranking or emerging.search· Upstar's search, the same as the site's search bar: topics by whole words (a name, slug, GitHub tag, language or keyword equal to the query, then every word of it in the topic's name, category or description) and every repository with an Upspotted_early· Repositories Upstar ranked before they took off: when and in which topic it first ranked them, their stars then and now. Most grown first.topic_ranking· Ranks a topic's GitHub repositories by star velocity (stars gained ÷ √stars before) over the last 24 hours, 7 days or 30 days, with the stars each gained. Ranks are the topic's own: when one is skipped, left_out says how many repositories Utrending· The fastest-rising GitHub repositories across every topic Upstar tracks, by star velocity or by stars gained, over 24 hours, 7 days or 30 days; new_only keeps repositories created in the last 7 days.
What "online" means: the server answered an MCP connection at the time of the check. It is not a guarantee of security, quality or continuous uptime. How we test: we open an MCP session and ask for the tool list, as an AI assistant would. We never run a tool and never send a key. Checked every few days. Method
Is this your server? Monitoring Pro: a check every 30 minutes and an email within the hour when it stops answering. Launch offer: $39.99 once, for life.
