Routing Policy

Use the backend that best matches user intent:

1. **MCP (default for vault data operations)**

  • Read/write/patch/search notes
  • Move/rename notes with `move_note`, then explicitly repair backlinks
  • Frontmatter and tag updates
  • Metadata and batch note operations

2. **Obsidian CLI/App context (only when app context is needed)**

  • Open a note in Obsidian from URI
  • Trigger app/plugin workflows that MCP cannot perform

3. **CLI git (sync/backup workflows)**

  • Initialize repo, configure remote, commit, pull, push
  • Periodic or manual vault backup/sync requests

When a request is ambiguous, pick MCP first unless the user explicitly asks for sync/backup/git/app behavior.

Safe Note Rename Workflow

Use MCP `move_note` for every note move or rename, even when Obsidian is running. Do not invoke the Obsidian CLI `move` command automatically: delayed link rewrites can apply stale byte offsets to notes edited after the move began, silently corrupting unrelated content ([#176](https://github.com/bitbonsai/mcpvault/issues/176)). Reconsider CLI moves only after an upstream fix has been independently retested.

Backlink preservation is an explicit, verifiable second step:

1. Before moving, search for the old wikilink target using both its vault-relative path and filename without the extension. If Obsidian is running, its read-only `backlinks` command may supplement discovery, but it does not replace the MCP search. 2. Move the note with MCP `move_note`. 3. Read each referring note and patch only exact wikilink targets, including embeds and links with aliases or fragments. Preserve display text (`|alias`) and `#heading` / `#^block-id` suffixes while changing the target. 4. Search again for the old path and basename. Report any remaining references instead of claiming success. 5. `search_notes` returns at most 20 results. If a search reaches that cap, or the old basename is ambiguous, tell the user exhaustive backlink repair cannot be proven and ask before continuing with a broader scan.

Report the move and backlink repair separately: which note moved, how many referring notes changed, and any stale references that remain.

Gotchas

1. **patch_note rejects multi-match by default.** With `replaceAll: false`, if `oldString` appears more than once the call fails and returns `matchCount`. Set `replaceAll: true` only when you mean it, or add surrounding context to make the match unique.

2. **patch_note matches inside frontmatter.** The replacement runs against the full file including the YAML block. A generic string like `title:` will match frontmatter fields. Include enough context to target the right occurrence.

3. **patch_note forbids empty strings.** Both `oldString` and `newString` must be non-empty and non-whitespace. To delete text, use `newString` with a single space or restructure the note with `write_note`.

4. **search_notes returns minified JSON.** Fields are abbreviated: `p` (path), `t` (title), `ex` (excerpt), `mc` (matchCount), `ln` (lineNumber), `uri` (obsidianUri). Hard cap of 20 results regardless of `limit`.

5. **search_notes multi-word queries score terms individually AND as a phrase.** Each term is OR-matched, so a document matching any term appears in results. The full phrase gets an additional scoring boost.

6. **write_note auto-creates directories.** Parent folders are created recursively. In `append`/`prepend` mode, if the note doesn't exist it's created. Frontmatter is merged (new keys override) in append/prepend; replaced entirely in overwrite.

7. **delete_note requires exact path confirmation.** `confirmPath` must be character-identical to `path`. No normalization, no trailing-slash tolerance. Mismatch silently fails with `success: false`.

8. **move_file needs double confirmation.** Both `confirmOldPath` and `confirmNewPath` must exactly match their counterparts. Use `move_note` for markdown renames (text-aware, no confirmation needed); use `move_file` only for binary files or when you need binary-safe moves.

9. **manage_tags reads from two sources but writes to one.** `list` merges frontmatter tags + inline `#hashtags`. `add`/`remove` only modify the frontmatter `tags` array. Inline tags are never touched.

10. **read_multiple_notes never rejects.** Uses `allSettled` internally. Failed files appear in the `err` array; successful ones in `ok`. Always check both. Hard limit of 10 paths per call.

Error Recovery

| Error | Next step | |-------|-----------| | patch_note "Found N occurrences" | Add surrounding lines to `oldString` to make it unique, or set `replaceAll: true` | | delete_note / move_file confirmation mismatch | Re-read the note path with `read_note` or `list_directory`, then retry with the exact string | | search_notes returns 0 results | Try single keywords instead of phrases, toggle `searchFrontmatter`, or broaden with partial terms | | read_multiple_notes partial `err` | Verify failed paths with `list_directory`, fix typos or missing extensions, retry only failed ones |

Git Sync Mode

When the user asks to "sync", "backup", or "store my vault with git", use CLI git with this behavior:

1. Run a **preflight** before changing anything:

  • `git` available
  • current directory is a git repo (or prompt to initialize)
  • `git config user.name` and `git config user.email` are set
  • at least one remote exists for push/pull sync

2. If preflight is incomplete, ask exactly one targeted question with a recommended default.

  • Use askuserquestion for decisions that materially change behavior.
  • Good examples:
  • "No git repo found. Initialize one in this vault now? (Recommended: Yes)"
  • "
