AI Toolkit
Discover trending skills, MCP servers, plugins, agents, and companion tools for your AI workflow.
Recently trending · Sources checked October 25, 2026
Selected from GitHub Trending this week and this month, across relevant language lists. Weekly signals are preferred where available. Entries with star-growth data are ordered by observed stars gained per day; every card shows its original window.
Existing listings also retain attributed growth from The Skill Leaderboard, Selan, or Favz where applicable. Configuration-adoption signals follow measured star growth. This is a curated selection of relevant tools, not an exhaustive GitHub category ranking. Extensions includes agent companion utilities.
Compatibility and setup were checked against official documentation. Listings have not been hands-on tested by Website Explosion. Free refers to the add-on; assistant usage and optional services may cost extra.
