It organizes nearly 600,000 mods by function, agent, vendor, and category, helping users explore options for work ranging from software development and testing to research, security, writing, and project management.

Unlike a directory that simply counts listings, agentmods measures practical details intended to help users assess and manage their setups. Entries show estimated token costs per session, security scan results with explanations, and whether a mod is an original or a copy. The catalogue also tracks repository changes and identifies copies and forks, linking them to their originals. Users can search listings, browse curated rankings such as trending and best-performing mods, and review token costs through the npx agentmods tool. By combining discovery, measurement, security information, and change tracking in one place, agentmods helps developers compare agent extensions and make more informed choices about what to add to their workflows.
