Hjarni Notes

Generate a one-time upload URL for attaching a file to a note. Share this URL with the user so they can upload directly in their browser — saves tokens by avoiding base64 encoding. The link expires after 30 minutes. Use files-check_upload to verify completion. Required: note_id (integer). Optional: description.

Get a temporary download URL for a file attached to a note. Share the URL with the user to download in their browser. URL expires after a few minutes. Required: note_id (integer), file_id (integer, from notes-get response).

Permanently remove a file attachment from one of your personal notes (personal notes only). This action is irreversible. Required: note_id (integer), file_id (integer, from notes-get response).

Get LLM instructions at the specified level. Call with level 'brain' early in conversations to learn user preferences. Optional: level ('brain'|'personal_root'|'container'|'team'), defaults to 'brain' if omitted or blank; the response echoes resolved_level and defaulted_level (true when the level was defaulted). Optional: id (integer, required for 'container' and 'team' levels). 'container' level returns the full inheritance chain (personal root -> ancestors -> container).

Update LLM instructions at the specified level. Required: level ('brain'|'personal_root'|'container'|'team'), instructions (string). Optional: id (integer, required for 'container' and 'team'), mode ('replace' default|'append'). The 'container' level updates personal containers only; to set instructions for a team, use level 'team' (team owners only). In 'replace' mode (default), the provided text overwrites existing instructions. In 'append' mode, the text is appended to existing instructions with a newline separator. Always read current instructions first before replacing to avoid losing existing content.

Create or remove a bidirectional link between two notes. Required: action ('link'|'unlink'), source_note_id (integer), target_note_id (integer). Prefer wiki-link syntax [[id:Title]] in note bodies for inline linking — use this tool for programmatic links without modifying body text. Unlinking is destructive and cannot be undone.

Get the connected user's profile, plan, onboarding state, team memberships, and note quota in a single call. Call this once at the start of a conversation so you can greet the user by first name, run the onboarding script only when needed, route notes to the right team space, and avoid suggesting Pro features to free users. Returns onboarding.completed (boolean) and onboarding.missing_steps (array of 'connect_mcp' | 'first_note'), which together tell you what, if any, setup is left. Exposes the user's email address and plan — same data the user sees in account settings, but never billing or token metadata. No parameters required.

Create a new note. Required: title (string). Always include a 2-3 sentence summary too (required by convention, even though the schema only enforces title) so the note is useful to future LLM sessions. Optional: body (Markdown with [[id:Note Title]] wiki-links), summary, source_url, container_id, tag_list (comma-separated), team_id (to create in a team), review_after (ISO 8601 datetime, only set this for time-boxed notes that should flag themselves stale after a date). A new note starts verified (status 'active'). Example: {title: 'Meeting Notes', body: '## Agenda\n...', container_id: 5, tag_list: 'meetings, q4'}.

Move a note to Trash. This is RECOVERABLE — the note (with its body, attachments, and history) is restorable with notes-restore until its purge date (default 30 days); it is not an immediate permanent erase. Deleting the wrong note can be undone with notes-restore. Works on your own personal notes and on team notes where you have the editor role. You cannot delete notes in a shared container (only the owner can). Required: id (integer).

Get a single note by ID, including its full Markdown body, tags, container path, linked notes (outgoing), backlinks (incoming links from other notes), file attachments, and inherited LLM instructions. Required: id (integer).

Read a note's revision history and provenance: who wrote each version (you, the user, or which AI client), when, and what changed. Use it to attribute facts to their source and to see recent edits before making your own. Read-only. Required: id (integer). Optional: limit (default 20, max 100), before_seq (paginate to older revisions), include_body (boolean — reconstruct each version's full text), seq (integer — return only that revision, with its full reconstructed body).

List notes with optional filtering, sorting, and pagination. Returns paginated results. Optional: team_id (integer) to list team notes, scope ('active'|'archived'|'inbox'|'favorited'|'trashed'), container_id (integer) with include_nested (boolean), tags (array of strings, AND logic), tag_ids (array of integers, AND logic), summary_stale (boolean, filter to notes with outdated summaries), stale (boolean, filter to notes whose freshness is stale — past their review_after date or unverified for a while), sort ('recent'|'oldest'|'title'), page (integer, default 1), per_page (integer, max 100, default 25). container_id can be combined with team_id to list a specific team container. Example: list ruby-tagged notes in a container: {container_id: 5, tags: ['ruby']}.

Restore a note that notes-delete moved to Trash, bringing back its body, tags, attachments, and history. Only works before the note's purge date. Required: id (integer) — the same note id you deleted.

Revert a note's body to an earlier revision (find the seq via notes-history). This does NOT erase history — it appends a NEW revision whose body equals the chosen earlier one, attributed to you, so the revert can itself be undone. Use only when the user explicitly asks to undo a change. Optional expected_lock_version (from notes-get) rejects the revert if the note changed since you read it, instead of clobbering that change. Required: id (integer), seq (integer).

Update a note: edit its content, move it to a different folder (set container_id, or null for the inbox), archive/favorite it, or change its tags. This is the tool for moving notes between folders; there is no separate move tool. Required: id (integer). Optional content (exactly one body-mutation mode at a time): title, body (full replace), append_body (appends to existing body), insert_after + insert_body (insert text immediately after a unique anchor snippet from the existing body), insert_before + insert_body (insert before a unique anchor), replace_find (+ optional replace_with) (replace a unique snippet; omit replace_with entirely to delete the snippet). Markdown-structure ops (heading/section/checklist aware — safer than eyeballing a unique snippet on long notes): replace_section + section_body (replace everything UNDER a heading, keeping the heading line); append_to_section + section_body (add content at the END of a section — the safe 'insert under heading' when you don't know its last line); rename_heading + new_heading (rename a heading in place, preserving its level unless new_heading carries its own '#'); check_item / uncheck_item (tick/untick a checklist item by its text, e.g. '- [ ] ship it'). Headings and checklist items must each match exactly one line. Anchor and find snippets must match exactly once; include enough surrounding context to disambiguate. Also optional: summary, source_url. Freshness: verified (boolean — pass true to mark the note re-confirmed as still true right now; only send this after the user has actually confirmed it), review_after (ISO 8601 datetime to time-box the note, or null to clear it). Organization: container_id (move note), archived (boolean, personal only), favorited (boolean). Tags: tag_list (full replace, comma-separated), add_tags, remove_tags. tag_list takes precedence over add_tags/remove_tags. Concurrent edit safety: pass expected_lock_version (the lock_version you saw when you last read the note via notes-get / notes-list / search) whenever you want a stale-write guard. If it doesn't match the current version, the update is rejected with the current state included so you can re-read and re-apply. Surgical edits (append_body / insert_after / insert_before / replace_find) are anchor-based and so don't *need* expected_lock_version for their body change — but if you also change title / summary / container_id alongside, those fields can still silently overwrite a newer save unless you supply expected_lock_version. Examples: insert under a heading {id: 42, append_to_section: 'Open Questions', section_body: '- Should we ship Friday?'}; replace a section {id: 42, replace_section: '## Status', section_body: 'Shipped 🎉'}; rename a heading {id: 42, rename_heading: 'TODO', new_heading: 'Done'}; tick a checklist item {id: 42, check_item: 'ship it'}; fix a typo {id: 42, replace_find: 'recieved', replace_with: 'received'}; safe full rewrite {id: 42, body: '...', expected_lock_version: 5}. Every edit is recorded as a named, revertable revision attributed to you — use notes-history to see who changed what, and notes-revert to undo a change.

Search across notes, containers, and tags in one call. Returns results grouped by type with pagination metadata (total_count, page, per_page, total_pages). Required: query (string). Optional: types (array, default all three), search_scope ('all'|'personal'|'team:<id>'), scope ('active'|'archived'), container_id (integer, ignored when search_scope is 'all'), tags (array, AND logic), tag_ids (array, AND logic), include_nested (boolean), include_body (boolean, default false — when true each note includes its full body), created_after / created_before / updated_after / updated_before (ISO 8601 datetime filters on note timestamps), page (integer, default 1), per_page (integer, default 25, max 100). Note results include a snippet of the matching portion.

Create a new tag. Check tags-list first to avoid duplicates. Required: name (string). Tag names are automatically lowercased.

List all tags with their notes_count. Paginated. Optional: page (integer), per_page (integer).

Rename, merge, or delete a tag — the cleanup tools for the tag list (this operates on the tag itself, unlike notes-update which only edits one note's tags). Required: action ('rename'|'merge'|'delete') and the tag to act on via name (string, case-insensitive) or tag_id (integer). For 'rename' also pass new_name. For 'merge' also pass the destination via target_name or target_id: every note on the source tag is moved onto the destination and the source tag is deleted — ideal for collapsing duplicates like 'machine learning' into 'machine-learning'. If target_name names a tag that doesn't exist yet, it's created, so you can merge straight into a clean canonical name without creating it first. 'delete' removes the tag from all its notes and deletes it; deleting a name that doesn't exist succeeds as a no-op (already_absent: true), so it's safe to retry. Merge and delete are destructive and cannot be undone; check tags-list first.

Get team details including the 10 most recent notes. Required: id (integer).

Invite a teammate to a team by email (team owner only). Required: team_id (integer, from teams-list), email (string). Emails an invite; they must accept from that exact address, and a per-seat charge is added only when they accept.

List all teams the user is a member of, including members_count, notes_count, and containers_count for each team. No parameters required.
