notion-sync

notion-sync is a skill for Claude Code, Codex from fuyuxiang/echo-agent. It costs 23 tokens per session (521 once invoked), scanned B, original, MIT.

A Python-based connection to Notion for reading, creating, and updating pages and databases. Notion is a workspace application for documents and structured tables.

In plain words
What is it for?
Use it to search Notion, read page blocks, query databases, create pages, and update workspace content through the Notion API.
Why use it?
It lets an agent work with Notion content programmatically instead of copying information manually. Access requires an integration token and permission to the target pages or databases.

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 B, and why

notion-sync scanned grade B with 1 finding 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 4d ago.

The scan reads SKILL.md. This mod also ships 1 executable file (scripts/notion_client.py), listed below but not scanned — reading those needs a real analyzer, not pattern matching.

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.

Sends data to an external URLmediumData exfiltration

A POST to an outside endpoint may be telemetry or may be exfiltration; either way the mod talks to somewhere, and you should know where.

What it actually says

Notion Sync

Notion API integration for pages, databases, and content management.

Setup

  1. Create integration at https://www.notion.so/my-integrations
  2. Get Internal Integration Token
  3. Share target pages/databases with the integration
  4. Set environment: export NOTION_API_TOKEN=secret_xxx

Script

python3 scripts/notion_client.py --token secret_xxx databases
python3 scripts/notion_client.py --token secret_xxx query <database-id> --limit 20
python3 scripts/notion_client.py --token secret_xxx create <database-id> "Page Title" --content "Body text"

API Usage

import httpx

HEADERS = {
    "Authorization": f"Bearer {NOTION_API_TOKEN}",
    "Notion-Version": "2022-06-28",
    "Content-Type": "application/json",
}

# Search
resp = httpx.post("https://api.notion.com/v1/search",
    headers=HEADERS,
    json={"query": "project plan"})

# Read page blocks
resp = httpx.get(f"https://api.notion.com/v1/blocks/{page_id}/children",
    headers=HEADERS)

# Create page
resp = httpx.post("https://api.notion.com/v1/pages",
    headers=HEADERS,
    json={
        "parent": {"page_id": parent_id},
        "properties": {"title": [{"text": {"content": "New Page"}}]},
        "children": [
            {"paragraph": {"rich_text": [{"text": {"content": "Hello"}}]}}

Files

What ships with it

1 file beside SKILL.md in the same directory: the scripts, references and assets a skill reads on demand. Not counted in the per-session cost; read them before you install if any of them is executable.

Changes

What this file has done since we first saw it

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.
