/sync-notion-pages

Bidirectional sync between Obsidian notes and Notion pages for collaborative planning.

Usage

/sync-notion-pages                      # Check all tracked pages for changes
/sync-notion-pages <note>               # Sync a specific note
/sync-notion-pages --push <note>        # Force push to Notion
/sync-notion-pages --pull <note>        # Force pull from Notion
/sync-notion-pages --link <note> <url>  # Link note to Notion page
/sync-notion-pages --unlink <note>      # Remove sync tracking from note
/sync-notion-pages --status             # Show sync status dashboard

Prerequisites

• Notion MCP server must be connected (tools like mcp__MCP_DOCKER__API-retrieve-a-page)
• Notes must have notionPageId in frontmatter to be tracked

Instructions

Phase 1: Parse Command

1. Identify operation mode:

   • No args: Check all tracked pages
   • <note>: Sync specific note (detect direction automatically)
   • --push <note>: Force push local → Notion
   • --pull <note>: Force pull Notion → local
   • --link <note> <url>: Link existing note to Notion page
   • --unlink <note>: Remove sync tracking
   • --status: Show dashboard

2. If note specified, find it:

   • Search by filename or title
   • Verify note exists
   • Check if tracked (has notionPageId)

Phase 2: Load Manifest

Read .claude/sync/notion-pages-manifest.json:

{
  "version": "1.0",
  "lastFullSync": "2026-01-20T14:00:00Z",
  "trackedPages": {
    "<pageId>": {
      "localFile": "Trip - Lisbon March 2026.md",
      "notionUrl": "https://...",
      "notionLastEdited": "2026-01-20T14:30:00Z",
      "localLastModified": "2026-01-20T15:00:00Z",
      "lastSynced": "2026-01-20T14:00:00Z",
      "syncStatus": "local-ahead"
    }
  }
}

Phase 3: Operations

3A: Link Operation (--link)

1. Parse Notion URL to extract page ID:

   • Format: https://www.notion.so/Page-Title-<pageId> or https://www.notion.so/<pageId>
   • Page ID is typically 32 characters with optional hyphens

2. Fetch page from Notion using mcp__MCP_DOCKER__API-retrieve-a-page:

   page_id: "<extracted-page-id>"
   

3. Add sync fields to note frontmatter:

   notionPageId: "<pageId>"
   notionUrl: "<full-url>"
   lastSynced: null
   syncStatus: unsynced
   

4. Add entry to manifest

5. Report success

3B: Status Operation (--status)

1. For each tracked page in manifest:

   • Fetch Notion page last_edited_time
   • Get local file modified timestamp
   • Calculate sync status

2. Display dashboard:

   # Notion Page Sync Status
   
   | Note          | Status      | Local Modified   | Notion Modified  | Last Synced      |
   | ------------- | ----------- | ---------------- | ---------------- | ---------------- |
   | Trip - Lisbon | local-ahead | 2026-01-21 10:00 | 2026-01-20 14:30 | 2026-01-20 14:00 |
   

3. Summarise:

   • X pages synced
   • X pages local-ahead (need push)
   • X pages remote-ahead (need pull)
   • X pages in conflict

3C: Check/Sync Operation (default or specific note)

For each tracked page (or specific note):

1. Fetch Notion metadata:

   mcp__MCP_DOCKER__API-retrieve-a-page with page_id
   

   Extract last_edited_time

2. Get local file modified time:

   • Read file and check modified in frontmatter
   • Also check filesystem modified time as backup

3. Compare against lastSynced:

   localChanged = localModified > lastSynced
   remoteChanged = notionLastEdited > lastSynced
   
   Status:
   - synced: !localChanged && !remoteChanged
   - local-ahead: localChanged && !remoteChanged
   - remote-ahead: !localChanged && remoteChanged
   - conflict: localChanged && remoteChanged
   

4. Take action based on status:

   • synced: Report "No changes"
   • local-ahead: Auto-push to Notion
   • remote-ahead: Auto-pull from Notion
   • conflict: Prompt user for resolution

3D: Push Operation (--push or auto-push)

1. Read local note content:

   • Parse frontmatter
   • Extract markdown body (skip frontmatter and callouts)

2. Convert Markdown → Notion blocks:

   | Markdown | Notion Block Type | | ------------ | ---------------------- | --- | ----- | | # H1 | heading_1 | | ## H2 | heading_2 | | ### H3 | heading_3 | | paragraph | paragraph | | - item | bulleted_list_item | | 1. item | numbered_list_item | | - [ ] task | to_do (checked: false) | | - [x] task | to_do (checked: true) | | > quote | quote | | code | code | | | table | | table |

3. Clear existing Notion blocks:

   • Get current blocks: mcp__MCP_DOCKER__API-get-block-children
   • Delete each block: mcp__MCP_DOCKER__API-delete-a-block

4. Append new blocks:

   • Use mcp__MCP_DOCKER__API-patch-block-children to add converted blocks

5. Update timestamps:

   • Update frontmatter lastSynced to now
   • Update manifest with new sync time
   • Set syncStatus: synced

3E: Pull Operation (--pull or auto-pull)

1. Fetch Notion page content:

   mcp__MCP_DOCKER__API-retrieve-a-page with page_id
   mcp__MCP_DOCKER__API-get-block-children with block_id=page_id
   

2. Convert Notion blocks → Markdown:

   For each block, convert to markdown:

   function blockToMarkdown(block) {
     switch (block.type) {
       case "heading_1":
         return `# ${getRichText(block.heading_1.rich_text)}`;
       case "heading_2":
         return `## ${getRichText(block.heading_2.rich_text)}`;
       case "heading_3":
         return `### ${getRichText(block.heading_3.rich_text)}`;
       case "paragraph":
         return getRichText(block.paragraph.rich_text);
       case "bulleted_list_item":
         return `- ${getRichText(block.bulleted_list_item.rich_text)}`;
       case "numbered_list_item":
         return `1. ${getRichText(block.numbered_list_item.rich_text)}`;
       case "to_do":
         const checked = block.to_do.checked ? "x" : " ";
         return `- [${checked}] ${getRichText(block.to_do.rich_text)}`;
       case "quote":
         return `> ${getRichText(block.quote.rich_text)}`;
       case "code":
         return `\`\`\`${block.code.language}\n${getRichText(block.code.rich_text)}\n\`\`\``;
       case "divider":
         return "---";
       default:
         return "";
     }
   }
   
   function getRichText(richTextArray) {
     return richTextArray.map((t) => t.plain_text).join("");
   }
   

3. Preserve frontmatter:

   • Read current note frontmatter
   • Update modified to today
   • Update lastSynced to now
   • Set syncStatus: synced

4. Preserve local-only sections:

   • Keep callout blocks (e.g., > [!info])
   • Keep frontmatter
   • Replace body content

5. Write updated note

6. Update manifest

Phase 4: Conflict Resolution

When both sides changed since last sync:

1. Show diff summary:

   ## Conflict Detected: Trip - Lisbon March 2026
   
   **Local changes since 2026-01-20 14:00:**
   
   - Modified flights section
   - Added new activities
   
   **Notion changes since 2026-01-20 14:00:**
   
   - Collaborator added restaurant suggestions
   - Updated accommodation notes
   

2. Offer resolution options using AskUserQuestion:

   • Keep local (push to Notion)
   • Keep remote (pull from Notion)
   • Skip (resolve manually later)

3. Execute chosen resolution:

   • If keep local: Run push operation
   • If keep remote: Run pull operation
   • If skip: Leave status as conflict

Phase 5: Report

# Notion Page Sync Report

- Check for any formatting issues

Content Preservation Rules

Always Preserve in Local Note:

• Frontmatter (sync adds/updates specific fields)
• Local callout blocks (> [!info], > [!warning])
• Links to other Obsidian notes ([[Note Name]])

Always Push to Notion:

• Headings
• Paragraphs
• Lists (bulleted, numbered, tasks)
• Tables
• Code blocks

Handle Specially:

• Wiki-links: Convert [[Note]] to plain text when pushing
• Callouts: Skip when pushing (Notion doesn't support same format)
• Embedded content: Skip (handle manually)

Error Handling

Error	Action
Notion API rate limited	Wait and retry
Page not found	Remove from tracking, notify user
Invalid page ID	Report error, suggest re-linking
Network timeout	Retry once, then report
Malformed blocks	Skip block, continue, report at end

Manifest Location

.claude/sync/notion-pages-manifest.json

This is separate from the Confluence sync manifest at .claude/sync/manifest.json.

Example Workflow

First-time setup for a note:

User: /sync-notion-pages --link "Trip - Lisbon March 2026" https://www.notion.so/Lisbon-March-2026-2ee76da238c981459c88ca451e112c39

Claude:
1. Extracts page ID: 2ee76da238c981459c88ca451e112c39
2. Fetches Notion page to verify
3. Updates note frontmatter with sync fields
4. Adds to manifest
5. Reports: "Linked Trip - Lisbon March 2026 to Notion page"

Regular sync check:

User: /sync-notion-pages

Claude:
1. Loads manifest
2. For each tracked page, checks timestamps
3. Reports status for all pages
4. Offers to sync any that need it

Force push after local edits:

User: /sync-notion-pages --push "Trip - Lisbon March 2026"

Claude:
1. Reads local note
2. Converts to Notion blocks
3. Updates Notion page
4. Updates timestamps
5. Reports success
