About io.github.onetrueclaude-creator/mcp-knowledge-gaps
io.github.onetrueclaude-creator/mcp-knowledge-gaps is an MCP server published by onetrueclaude-creator in the Developer Tools category: find what your knowledge base mentions but doesn't actually explain.
Six months or more without a commit doesn't mean the server is broken, but check the open issues before depending on it in production.
Install
uvx mcp-knowledge-gapspip install mcp-knowledge-gapsThis server has no ConduID identity, so agent calls to it are not receipted. Pin the version you install and review the source before granting it credentials.

README
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

MCP Tools
| Tool | Tier | Description |
|---|---|---|
find_gaps |
Free | Scan a markdown vault and return concepts mentioned in multiple notes but without their own dedicated note. Applies fuzzy canonicalization and noise filtering. |
list_gaps_by_priority |
Free | Return gaps ranked by priority: frequency × diversity × novelty (higher = fill this gap first). |
generate_research_questions |
Pro | Generate prioritized research questions for the top N gaps. Each question comes with a priority score and factor breakdown. |
surprise_research_topic |
Pro | Sortition sampling — pick a random gap from the LOW-priority long tail. Breaks confirmation bias by surfacing topics you'd never pick yourself. |
export_review_queue |
Pro | Export a CSV of top-priority gap concepts, suitable for Anki or other spaced-repetition tools. Writes to output_csv and returns the row count. |
Pro tier
Unlocks research question generation with RL-weighted ranking, sortition sampling of long-tail gaps, and CSV review queue export.
