Read and write Notion data using Python + notion-client SDK. Authenticated via NOTION_API_KEY env var. Supports search, page CRUD (Markdown↔Blocks bidirectional conversion), database schema/query/create/add-row, block-level operations (append/update/delete), and comments. Trigger this skill whenever the user mentions "Notion", "notion", "notion-hub", "Notion page", "Notion database", "read Notion", "write Notion", "Notion API", or any scenario requiring programmatic read/write access to Notion data.

Notion Hub

Read/write Notion via notion-client Python SDK. All operations through a single CLI script.

Prerequisites

  • Environment variable: NOTION_API_KEY — Notion Internal Integration Token
  • uv: The script uses uv inline script metadata (notion-client>=3.0.0, httpx>=0.27). Dependencies are auto-installed on first uv run, no manual pip install needed.
  • Integration access: The integration must be connected to target pages/databases in Notion UI (Share → Connections → add integration)

CLI Script

Path: /var/minis/skills/notion-hub/scripts/notion_hub.py

Run: uv run --script --cache-dir /root/.cache/uv /var/minis/skills/notion-hub/scripts/notion_hub.py <command> [options]

Alias for brevity:

NH="uv run --script --cache-dir /root/.cache/uv /var/minis/skills/notion-hub/scripts/notion_hub.py"

Notion Filter Syntax Quick Reference

// Text property
{"property": "Name", "rich_text": {"contains": "keyword"}}

// Select
{"property": "Status", "select": {"equals": "Done"}}

// Multi-select
{"property": "Tags", "multi_select": {"contains": "Bug"}}

// Status
{"property": "Status", "status": {"equals": "In Progress"}}

// Checkbox
{"property": "Done", "checkbox": {"equals": true}}

// Date
{"property": "Due", "date": {"before": "2024-04-01"}}
{"property": "Due", "date": {"on_or_after": "2024-01-01"}}

// Number
{"property": "Score", "number": {"greater_than": 80}}

// Compound (AND)
{"and": [{"property": "Status", "status": {"equals": "Done"}}, {"property": "Priority", "select": {"equals": "High"}}]}

// Compound (OR)
{"or": [{"property": "Status", "status": {"equals": "Done"}}, {"property": "Status", "status": {"equals": "Archived"}}]}

Notion Sort Syntax

[{"property": "Created", "direction": "descending"}]
[{"property": "Name", "direction": "ascending"}]
[{"timestamp": "last_edited_time", "direction": "descending"}]

Property Value Syntax for db-add-row --props

The --props JSON maps property names to simple values. The script auto-detects types from the database schema:

TypeValue formatExample
titlestring"My Title"
rich_textstring"Some text"
numbernumber42
selectstring (option name)"High"
multi_selectcomma-separated string or array"Bug,Feature" or ["Bug","Feature"]
statusstring (status name)"In Progress"
dateISO date string or {start, end}"2024-03-15"
checkboxbooleantrue
urlstring"https://..."
emailstring"a@b.com"
relationcomma-separated IDs or array"id1,id2"
peoplecomma-separated user IDs"user_id"
filesURL string or array of URLs"https://file.png"

Workflow Tips

  1. First time: Run $NH search or $NH search --filter database to discover accessible pages/databases and get their IDs.
  2. Before writing to a database: Run $NH db-get <id> to see the schema (property names, types, select options).
  3. Reading a page: Use page-read for Markdown output — much more readable than raw blocks.
  4. Writing a page: Use page-write --text with Markdown — the script auto-converts to Notion blocks.
  5. IDs: Both raw UUIDs and full Notion URLs are accepted for all ID parameters.
  6. Pagination: All list/query commands auto-paginate. Use --limit to cap results.

Error Handling

All errors return {"error": "..."} JSON. Common issues:

  • 401: Invalid or expired token
  • 403: Integration not connected to the target page/database
  • 404: Page/database not found or not accessible
  • 429: Rate limited (auto-retry is not implemented; wait and retry)

Security Notes

  • NOTION_API_KEY: Never echo, print, or expose the token value in conversation. Always reference via $NOTION_API_KEY.
  • User emails: The users command auto-masks email addresses (e.g. w***3@gmail.com). Do not attempt to retrieve or display full emails.
  • File URLs: Notion internal file URLs contain signed AWS tokens. The script auto-strips these from Markdown/block output. If you need to download a file, use blocks-get --raw and handle the URL in a script without printing it.
  • Recursion depth: blocks-get-all and page-read cap at depth 10 to prevent API call storms.
