onenote

onenote is a skill for Claude Code from sandraschi/onenote-mcp. It costs 0 tokens per session (1,024 once invoked), scanned A, original, MIT.

A connection between an AI assistant and Microsoft OneNote through Microsoft's Graph API. OneNote is Microsoft's note-taking app, and this connection can browse, search, read, and create notebook pages.

In plain words
What is it for?
Use it to authenticate, list notebooks and sections, inspect pages, search note text, read full page content, and create new pages.
Why use it?
It lets the assistant find and work with notes without manually opening notebooks and copying their contents.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

onenote scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 17d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

OneNote MCP — Skill

What this server does

OneNote MCP connects an AI assistant to Microsoft OneNote through the Microsoft Graph API: browsing notebooks/sections/pages, reading full page content (HTML), creating and appending pages, and title + full-text search across the user's notes. 26 tools + 1 prompt (onenote_triage), dual transport (stdio + HTTP streamable on 10907).

Tool categories

Category Tools
Auth authenticate, onenote_save_access_token
Discovery onenote_list_notebooks, onenote_get_notebook, onenote_list_sections, onenote_list_pages, onenote_get_notebook_toc, onenote_recent (what changed)
Structure (create) onenote_create_notebook, onenote_create_section, onenote_create_section_group, onenote_list_section_groups. Graph cannot rename or delete notebooks/sections.
Edit onenote_update_page (element-level replace/insert/prepend/append, retitle; Graph cannot delete elements - blank with replace), onenote_delete_page (destructive: confirm with the user first)
Content onenote_get_page (output_format="markdown" for readable text; include_ids=True for element IDs), onenote_create_page (pass section_id to choose the section; content_format="markdown" for Markdown, - [ ] becomes a OneNote to-do), onenote_append_page (plain text or Markdown), onenote_search_pages (mode title or fulltext), onenote_get_links (web + app link to share a page or notebook)
Backup onenote_export, onenote_export_status (Markdown files under data/exports)
Index onenote_index_start, onenote_index_status (local FTS5 over page bodies; build once, then full-text works)
Presentation show_notebooks_card (in-chat Prefab card)
Guidance onenote_triage prompt (discover/retrieve/map/capture steering)
System onenote_help, shutdown_server

Best practices

  1. Sign in first. If any tool returns No access token available, the user signs in (webapp Notebooks page, browser auth-code flow) or the agent calls authenticate() (device-code flow) before anything else.
  2. Navigate top-down. Start with onenote_list_notebooks(), then onenote_get_notebook_toc(notebook_id=...) to see sections + pages in one call, then onenote_get_page(page_id=...) for content. IDs are opaque Graph IDs - always pass them through, never truncate.
  3. Creating pages takes HTML content: onenote_create_page(notebook_id=..., title="Meeting Notes", content="<h1>...</h1><p>...</p>").
  4. Search (onenote_search_pages) is a TITLE match across all notebooks (Microsoft removed full-text OneNote search; section-heavy accounts are walked TOC-by-TOC) - use it when the user describes a note instead of naming a notebook. For body text, build the index once (onenote_index_start) and search mode="fulltext".
  5. Page content is HTML. Read it as-is; render/sanitize before display (the webapp uses DOMPurify).

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.

onenote is a skill published in the GitHub repository sandraschi/onenote-mcp (1 stars, last pushed today), licensed MIT. It costs nothing until one of its globs matches a file; then it loads 1,024 tokens. A static security scan graded it A with 0 findings. No closer match exists in the catalogue, so it is treated as the original; first seen 2026-08-31.
