Search your personal knowledge vault using hybrid retrieval (semantic + keyword + knowledge graph). Returns cited passages from your notes.

Given a concept or entity name, find everything connected to it in the knowledge graph. Returns related entities and the typed relationships between them (CITES, INFLUENCES, EXTENDS, CONTRASTS_WITH, etc) with the evidence spans that justify each edge.

Surface forgotten connections in your vault. Finds notes and concepts that are semantically related but never linked, and clusters of knowledge you may have forgotten about.

Add a web URL to your vault. Loom will fetch, parse, and index it. Supports general web pages, arXiv papers, Wikipedia articles, HN threads, and more.

Get statistics about your knowledge vault: total documents, chunks indexed, entity count, and top concepts by frequency.

Diagnose vault hygiene: orphan notes (no wikilinks in or out), broken wikilinks (point to missing files), stale notes (old and weakly connected), and tag issues (likely typos, inconsistent casing). Works in vector-only mode; uses the graph for connectivity when Neo4j is available.

Trigger a Loom background loop on demand. 'vault_health' writes a health report to the vault; 'stale_check' writes a stale-notes review; 'index_freshness' re-indexes files changed since the last index pass; 'all' runs every loop that is due. Reports are written into the vault's 'Loom Reports' folder.

Create a new markdown note in the vault. Refuses to overwrite existing files. Adds YAML frontmatter (source: mcp_create, plus any tags). Smart-write pipeline: suggests existing tags for near-duplicates, discovers wikilink candidates among existing filenames, and — when 'folder' is omitted — places the note in the folder of the most semantically similar existing note.

Edit one section of an existing note, located by heading (any level, fuzzy filename match). mode = replace | prepend | append. All content outside the targeted section is preserved. Returns the edited section for confirmation.

Read just one section of a note (from a heading to the next heading of equal or higher level). Fuzzy filename match. Lower token cost than reading the whole document.

Append content to the end of an existing vault note (fuzzy filename match). Simpler than edit_section — no heading needed.

Write a correction into the knowledge graph. With only 'subject', declares/upserts a single entity. With 'subject', 'relation', and 'object', asserts a typed relationship between two entities (creating either endpoint if missing). Valid relations: CITES, CONTRASTS_WITH, EXTENDS, INFLUENCES, UNCERTAIN_SAME_AS, UNTYPED_RELATION. Manual writes are tagged source='manual_mcp'. Use for surgical fixes, not bulk import.

Remove a single relationship from the knowledge graph by its edge_id. Get edge_ids from get_entity_neighbors. Deletes only the edge — both entities remain.

Remove an entity and ALL of its relationships from the knowledge graph (and any aliases left orphaned). Matches by exact canonical key — surgical, not fuzzy. Destructive and not reversible without re-indexing.
