Act on this, mostly facts

PlugVet publishes hygiene grades for AI agent skills and MCP servers

What to do

Check PlugVet grades before installing an agent skill or MCP server, but treat them as a hygiene screen.

Why

It lists 11,739 graded entries, though its scanner is not live yet and grades are not a security guarantee.

What the research found
