What is the best MCP servers, plugins and skill for a ai engineer?

By tashan's measured score the highest-ranked for this work are Context7, Context Mode, Agent Afk, Genshijin, Reprompter. The score combines upkeep and freshness, gated by real adoption; every input is public and linked to its source.

Are these audited for security?

Every capability tashan measures is checked against the OSV advisory database at the version you would install today, for install-time scripts, for build provenance, and for the permission surface its declared dependencies reach. The existence of a finding is always free to see. The audit reads public evidence only and never executes anything, so an empty result means nothing was declared, never that nothing is possible.
