Tools

Fourteen tools grouped by shape — readers fetch notes and metadata, writers create or surgically edit content, managers reconcile tags and frontmatter, and a guarded escape hatch dispatches Obsidian command-palette commands.

| Tool Name | Description |
|:----------|:------------|
| obsidian_get_note | Read a note as raw content, full structured form (content + frontmatter + tags + stat, with optional outgoing links), structural document map, or a single section. |
| obsidian_list_notes | List notes and subdirectories under a vault path. Recursive walk (default depth 2, max depth 20; 1000-entry cap) with optional extension and nameRegex filters. |
| obsidian_list_tags | List every tag found across the vault with usage counts, including hierarchical parents. Optional nameRegex post-filters the result set. |
| obsidian_list_commands | List Obsidian command-palette commands, optionally filtered by nameRegex on display name. Opt-in via OBSIDIAN_ENABLE_COMMANDS=true (paired with obsidian_execute_command). |
| obsidian_search_notes | Search the vault by text, JSONLogic, or BM25-ranked Omnisearch (when the plugin is reachable). Results paginate via opaque cursors. |
| obsidian_write_note | Create a note, replace a single section in place, or — with overwrite: true — clobber an existing file. Refuses whole-file writes against an existing path by default. |
| obsidian_append_to_note | Append content to a note. Without section, creates the file if missing. With section, appends to a specific heading, block, or frontmatter field (file must exist). |
| obsidian_patch_note | Surgical append / prepend / replace against a heading, block reference, or frontmatter field. |
| obsidian_replace_in_note | Body-wide search-replace inside a single note. Literal or regex matching with whole-word, whitespace-flexible, and case-sensitivity options; supports capture-group replacement. |
| obsidian_manage_frontmatter | Atomic get / set / delete on a single frontmatter key. |
| obsidian_manage_tags | Add, remove, or list tags. Defaults to the frontmatter tags: array; location: 'inline' or 'both' opts into mutating the note body. |
| obsidian_delete_note | Permanently delete a note. Elicits human confirmation when the client supports it. |
| obsidian_open_in_ui | Open a file in the Obsidian app UI, with failIfMissing and newLeaf toggles. |
| obsidian_execute_command | Execute an Obsidian command-palette command by ID. Opt-in via OBSIDIAN_ENABLE_COMMANDS=true. |

obsidian_get_note

Read a note in one of four projections, addressed by vault path, the active file, or a periodic note (daily, weekly, monthly, quarterly, yearly).

- format: "content" — raw markdown body
- format: "full" — content, frontmatter, tags, and file metadata; pass includeLinks: true to also parse outgoing wiki and markdown link references from the body (vault-internal only — external URLs are filtered)
- format: "document-map" — catalog of headings, block references, and frontmatter fields
- format: "section" — single heading/block/frontmatter section value (requires section); heading sections include the full subtree under that heading

Pair the document-map projection with obsidian_patch_note to discover edit targets before patching.

obsidian_search_notes

Up to three search modes selected by mode:

- text — substring match with surrounding context windows. contextLength controls characters of context per side of each match (default 100; bump it for more context per hit). Optional pathPrefix filter (text mode only — passing pathPrefix in any other mode is rejected with path_prefix_invalid_mode).
- jsonlogic — JSONLogic tree evaluated against path, content, frontmatter.<key>, tags, and stat.{ctime,mtime,size}; custom glob and regexp operators
- omnisearch — BM25-ranked search via the community Omnisearch plugin. Supports quoted phrases, -exclusion, path: / ext: filters, typo tolerance, and PDF + OCR coverage (via Text Extractor). Only present in the mode enum when the plugin's HTTP server is reachable at startup; the upstream hard-caps results at 50 — narrow the query to surface more (the response carries truncated: true when the cap was likely hit).

Results paginate via opaque cursors per the MCP 2025-11-25 spec: omit cursor for the first page, then pass nextCursor from the prior response. Every result carries totalCount (post-path-policy, pre-pagination); nextCursor is omitted on the last page. Text-mode hits are additionally clipped per file at maxMatchesPerHit (default 10) so a single match-heavy note can't blow the response budget — clipped hits carry truncated: true and totalMatches.

obsidian_write_note

Create or surgically replace, with a protective default against accidental whole-file overwrites.

- Without section — full-file PUT. Refuses to clobber an existing file unless overwrite: true is set. The file_exists (Conflict) error suggests obsidian_patch_note / obsidian_append_to_note / obsidian_replace_in_note for in-place edits.
- With section — PATCH-with-replace against the named heading/block/frontmatter field, leaving the rest of the file untouched. The overwrite flag is ignored in section mode.
