What is the best MCP server or skill for retrieval systems?

By tashan's measured score: Cocoindex Code, Opendataloader PDF, Context Engine, Pinecone, Episodic Memory. the score combines upkeep and freshness, gated by real adoption — every input is public and re-derivable, and no ranking position can be purchased.

Who does retrieval systems as part of their job?

This is work our corpus shows people doing that O*NET does not yet have a process step for — agentic tooling post-dates its software survey.

How is the ranking calculated?

From public signal only: npm download volume and publish cadence, GitHub push/release recency, contributor count, registry status, and how often a capability appears in real public agent configs. Nobody can pay to change a score, rank, or listing.

Who does this work

O*NET has no process step for this yet — its software occupations were surveyed before agentic tooling existed. We list it because the corpus plainly shows people doing it, and we say so rather than forcing it onto an unrelated step.
