PlugVet
PlugVet is an independent directory that grades AI agent skills and plugins in public.
PlugVet is an independent directory that grades AI agent skills and plugins in public. It provides a hygiene check and shows public grades, the checks behind them, and the date checked for coding agent skills, cursor plugins, codex plugins, and MCP servers. Users can look up grades using a GitHub link or browse thousands of graded entries. The platform reads the source to evaluate permissions, install steps, network usage, secrets, agent instructions, obfuscation, licence, and maintainer activity. Entries receive a letter grade from A to D, while F grades are held back and not listed.
