What data it sees

Do you need an account

No: the server works without sign-in

Penlog is an Apple Pencil journaling app for iPad that reads each handwritten page into structured tasks, notes, and priorities. Its MCP server exposes that journal to your AI: search pages by topic, pull open tasks with reconciled status, read a full day's page, and create or update tasks that appear on your handwritten page and sync to Notion.

Write by hand. Work with everything.

Tools

  • list_pages: list journal pages by date
  • get_page: full OCR text and structured lines for one day
  • search_pages: full-text search across handwritten pages
  • list_tasks: open and done tasks with reconciled status
  • create_task_seed: add a task onto a page (syncs to Notion)
  • update_task: mark done or undone, or edit a task

Server tool list (8)

Raw names from tools/list. Only developers need these.

list_pagesList the user's journal pages (most recent first), optionally filtered by date range. Use to see which days have entries before fetching a specific page.
get_pageFetch one day's full page by page_id: OCR text/markdown, the structured lines (tasks and notes), and signed PDF/PNG image URLs. Task lines carry reconciled status (done/open) and completed_date — trust these over how a task looks on the handwritten page.
search_pagesFull-text search the user's handwritten pages by topic or keyword. Use to answer 'what did I write/note about X'. Returns matching pages with snippets.
list_tasksList the user's tasks with reconciled status. Filter by status ('open'/'todo' or 'done'), since date, and limit. Use for 'what's on my list' or 'what's still open'.
create_task_seedAdd (seed) a task onto a target date's page — e.g. plan ahead or carry work forward to tomorrow — creating the page if missing. Idempotent on (text, owner) for open tasks. Best-effort push to the user's Notion Tasks DB when connected (returns notion_url + notion_task_id).
update_taskMark a task done/undone or edit its text, by task id. At least one of status/text required. Syncs to Notion if the task is linked.
searchSearch the user's handwritten journal pages by keyword or topic. Returns matching pages as {id, title, url} for citation. ChatGPT-compatible search tool — for richer results (snippets) agents can use search_pages instead.
fetchFetch the full OCR'd text of one journal page by its id (from a search result). Returns {id, title, text, url, metadata}. ChatGPT-compatible fetch tool — for structured lines + reconciled task status, use get_page instead.
