Install

Add this to your client's MCP configuration (Claude Desktop: claude_desktop_config.json; Cursor: .cursor/mcp.json; VS Code and others use the same "mcpServers" shape).

PYPI package mcp-knowledge-gaps
Claude Code 
claude mcp add mcp-knowledge-gaps -e 'KNOWLEDGE_GAPS_LICENSE=<your knowledge_gaps_license>' -- uvx mcp-knowledge-gaps==0.1.0
JSON configuration (Claude Desktop, Cursor, VS Code) 
{
    "mcpServers": {
        "mcp-knowledge-gaps": {
            "command": "uvx",
            "args": [
                "mcp-knowledge-gaps==0.1.0"
            ],
            "env": {
                "KNOWLEDGE_GAPS_LICENSE": "<your knowledge_gaps_license>"
            }
        }

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
Claude Desktop

Add to claude_desktop_config.json:

{
  "mcpServers": {
    "knowledge_gaps": {
      "command": "uvx",
      "args": ["mcp-knowledge-gaps"]
    }
  }
}

MCP Tools

ToolTierDescription
find_gapsFreeScan 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_priorityFreeReturn gaps ranked by priority: frequency × diversity × novelty (higher = fill this gap first).
generate_research_questionsProGenerate prioritized research questions for the top N gaps. Each question comes with a priority score and factor breakdown.
surprise_research_topicProSortition sampling — pick a random gap from the LOW-priority long tail. Breaks confirmation bias by surfacing topics you'd never pick yourself.
export_review_queueProExport 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.

License activation — any one of these works:
