Mcp Knowledge Gaps

Scans your markdown knowledge base (Obsidian, Logseq, or any folder of .md files) and surfaces concepts that appear across multiple notes but never get their own explanation. The free tier gives you find_gaps and list_gaps_by_priority, which rank missing concepts by frequency, diversity, and novelty. Pro adds generate_research_questions for guided learning, surprise_research_topic for sortition sampling from the long tail to break confirmation bias, and export_review_queue to pipe gaps into spaced repetition tools. Licenses verify offline via JWT. Reach for this when your second brain has grown large enough that you've lost track of what you reference but never actually learned.
