Knowledge Gaps tools (5)

write = sends, deletes, buys or posts

Read from the package source without running it. The installed server may list more.

  • export_review_queue

    [Pro] Export a CSV of top-priority gap concepts for Anki or other spaced-repetition tools. Writes to output_csv and returns the row count.

  • find_gaps

    Scan a markdown vault and return concepts mentioned in multiple notes but without their own dedicated note. Applies fuzzy canonicalization and noise filtering.

  • generate_research_questions

    [Pro] Generate prioritized research questions for the top N gaps. Each question comes with a priority score and factor breakdown.

  • list_gaps_by_priority

    Return gaps ranked by priority: frequency × diversity × novelty (higher = fill first).

  • surprise_research_topic

    [Pro] Sortition sampling — pick n random gaps from the LOW-priority long tail. Breaks confirmation bias by surfacing topics you'd never pick yourself.

<!-- mcp-name: io.github.onetrueclaude-creator/mcp-knowledge-gaps -->

mcp-knowledge-gaps

Find what your knowledge base mentions but doesn't actually explain.

Find concepts mentioned but never defined in your markdown knowledge base (Obsidian vault, Logseq graph, any folder of .md files). Uses fuzzy canonicalization to avoid false positives, ranks gaps by frequency × region-diversity × novelty, generates prioritized research questions, and samples from the long tail via sortition to break confirmation bias in your research queue.

Install

pip install mcp-knowledge-gaps
# or
uvx mcp-knowledge-gaps

Usage

Claude Code

claude mcp add mcp-knowledge-gaps -- mcp-knowledge-gaps
