  • vault_list_filesList Files

    List non-markdown files in the vault or a folder — images, canvases, PDFs, data files — with per-file byte sizes and per-extension counts. Example: vault_list_files({}) — non-markdown files across the whole vault Example: vault_list_files({ folder: "attachments" }) Example: vault_list_files({ extensions: [".png", ".jpg"], limit: 20 }) When to use: discovering what files exist before reading them with vault_read_file. vault_list_notes and vault_search_by_folder cover only markdown notes, and beyond notes vault_search indexes only canvas, PDF, and text-format files, so this is the discovery su…

  • vault_list_memory_filesList Memory Files

    Description is built at runtime.

  • vault_list_notesList Notes

    List .md file paths in the vault, optionally filtered by folder and/or glob pattern. Returns paths only — not content or metadata. Example: vault_list_notes({ folder: "Projects" }) Example: vault_list_notes({ glob: "**/*session-log*.md" }) Example: vault_list_notes({ folder: "Projects", glob: "*.md" }) — the folder's top-level notes only When to use: Browsing what exists in a folder by filename, or finding notes matching a path pattern. Prefer vault_search_by_folder when you need metadata (tags, type, related) along with paths. Prefer vault_search for content-based discovery. Use vault_read_…

  • vault_list_property_keysList Property Keys

    Discover all property keys in the vault with note counts and sample values. Lets you understand the vault's metadata schema without reading individual notes. Example: vault_list_property_keys() returns [{ key: "tags", count: 342, sample_values: ["session-log", "project"] }, ...] Example: vault_list_property_keys({ folder: "Projects" }) — the keys used under Projects/ only When to use: Discovering what properties exist before searching by property. Good first step for vault orientation alongside vault_list_tags. Prefer vault_list_property_values when you need the full list of values for a spe…

  • vault_list_tagsList Tags

    List all tags in the vault with note counts, ordered by count descending, then by tag name. Only frontmatter tags Obsidian accepts are counted, not inline #tags. Spellings that differ only in letter case are one tag, shown as the spelling written most often. Each hierarchical tag appears as one full entry, not split into segments. Count is unique notes, not occurrences. Example: vault_list_tags() returns [{ tag: "session-log", count: 42 }, { tag: "project/vault-cortex", count: 8 }, ...] When to use: Discovering what tags exist before searching by tag. Good first step for vault orientation. P…

  • vault_recent_notesRecent Notes

    List recently modified or created notes, sorted by timestamp — a time-ordered window into the vault, not a date-range filter. Example: vault_recent_notes({ sort_by: "modified", limit: 10 }) Example: vault_recent_notes({ sort_by: "created", limit: 5 }) When to use: Catching up on vault changes, finding recent work, or orienting after a break. Prefer vault_search for content-based discovery, including a text query limited to a date range (its created and modified filters). Prefer vault_search_by_folder for browsing a specific folder. Parameters: - sort_by + limit interact: "modified" uses fil…

  • vault_search_by_propertySearch by Property

    Find notes where a frontmatter property matches a value. Example: vault_search_by_property({ key: "status", value: "in-progress" }) Example: vault_search_by_property({ key: "type", value: "session-log", folder: "Code Projects" }) When to use: Finding notes by metadata when you don't have a text query. Prefer vault_search when you also have a text query (it supports property filters too). Prefer vault_search_by_tag for tag-specific queries (supports hierarchical prefix matching). Use vault_list_property_keys to discover valid keys and vault_list_property_values to see what values a key takes.…
