This server mines your markdown vault for notes you've stopped thinking about. It uses wikilink graph structure and modification times to find dormant, poorly linked, or orphaned notes, then runs a DMN-inspired replay cycle that samples them with a weighted bias and generates cross-domain bridge queries to surface unexpected connections. The free tier gives you `find_dormant_notes` and `find_orphan_notes` for basic discovery. The Pro tier unlocks `suggest_replay_cycle` for the full sampling algorithm, `find_cross_domain_bridges` to connect notes across vault directories, and `random_deep_cut` for serendipitous pulls. Reach for this when your second brain has gotten too big to remember what's in it, or when you want to break out of only revisiting the same handful of notes.
Surface the notes you forgot you wrote — DMN replay for markdown vaults.
Surface the notes you've forgotten you wrote. Uses wikilink graph structure + file mtime to identify dormant notes (low link-in count, old, isolated) and the DMN-inspired replay cycle pattern from cognitive neuroscience: sample dormant notes with bias (40% random / 30% least-linked / 30% orphaned), generate cross-domain bridge queries between them, and surface the unexpected connections. Breaks the confirmation-bias loop where you only revisit the notes you already remember.

| Tool | Tier | Description |
|---|---|---|
find_dormant_notes | Free | List notes that are structurally dormant — low incoming wikilink count AND old mtime. These are the notes most at risk of being forgotten. |
find_orphan_notes | Free | List notes with zero incoming wikilinks — structurally isolated, the extreme case of dormancy. |
suggest_replay_cycle | Pro | Run the full DMN-inspired replay cycle: sample dormant notes with bias (40% random / 30% least-linked / 30% orphans), extract their concepts, generate cross-domain bridge queries between them, return notes to revisit. The core moat. |
find_cross_domain_bridges | Pro | Surface pairs of notes from DIFFERENT top-level directories that share concepts. These are the surprise connections — ideas that span your vault's silos. |
random_deep_cut | Pro | Pull a single random dormant note for serendipitous rediscovery. Think of it as your vault's shuffle-play button. |
Unlocks the full DMN replay cycle, cross-domain bridge discovery, and random deep-cut sampling.
