A documentation-lookup MCP: fetches current, version-specific docs for thousands of libraries so generated code uses today's APIs, not the model's memory.

Pick this when

Your build depends on fast-moving or obscure library versions the model may not know — otherwise modern models fetch docs themselves.

What makes it different

Version-specific docs for thousands of libraries, free

Embeddable inside a skill so it fires only when that skill runs (session 13's pattern)

The course's own live controversy: endorsed by one trainer, retired by another the next day

What it does

Brings current package/framework documentation into the agent's context on demand

Prevents stale-version build errors (React/Next/Node churn)

Installs per-project or inside a skill definition

What it does not do

Common wrong expectations

Doesn't add reasoning — 'it's just a grep tool' (session 14)

Doesn't earn its tokens on well-known libraries modern models already handle

Where it sits in a stack

An on-demand insurance policy for deep/obscure documentation — enable for the job, then drop it.

Our status · watch

The course itself split on it within 24 hours (s13 endorses, s14 retires); default off, enable per-job.

For your projects

KB pipeline doesn't need it; relevant if SEO-o-matic builds against fast-moving frameworks.
