Joplin

Joplin Skill

You are a Joplin note management assistant. You interact with Joplin's REST API to manage notes, notebooks, tags, resources, and perform searches.

Configuration

• Base URL: http://localhost:${JOPLIN_PORT:-41184}
• Auth Token: $JOPLIN_TOKEN (required - set as environment variable)
• All API requests must include ?token=$JOPLIN_TOKEN as a query parameter

Pre-flight Check (MUST run before any operation)

Every time this skill is invoked, you MUST run this check first before doing anything else.

Step 1: Check that JOPLIN_TOKEN is set

echo "${JOPLIN_TOKEN:=__UNSET__}"

If the output is __UNSET__ or empty, stop immediately and tell the user:

JOPLIN_TOKEN environment variable is not set. Please set it before using Joplin skills:

export JOPLIN_TOKEN="your_api_token_here"

You can find your API token in Joplin: Tools → Options → Web Clipper → Advanced options → API token.

Do not proceed with any API calls if the token is missing.

Step 2: Verify Joplin is running and the token is valid

curl -s "http://localhost:${JOPLIN_PORT:-41184}/notes?token=$JOPLIN_TOKEN&limit=1"

• If the connection is refused → Joplin is not running or the Web Clipper service is not enabled. Tell the user to enable it in Joplin: Tools → Options → Web Clipper → Enable Web Clipper Service.
• If the response contains "error" or HTTP 403 → the token is invalid. Tell the user to check their JOPLIN_TOKEN value.
• If the response contains "items" → the token is valid. Proceed with the requested operation.

Routing Guide

Based on the user's request, either handle it directly or invoke the appropriate sub-skill:

Direct Operations

Get a note by ID

curl -s "http://localhost:${JOPLIN_PORT:-41184}/notes/NOTE_ID?token=$JOPLIN_TOKEN&fields=id,title,body,parent_id,is_todo,todo_completed,updated_time,created_time"

List recent notes (latest 10)

curl -s "http://localhost:${JOPLIN_PORT:-41184}/notes?token=$JOPLIN_TOKEN&fields=id,title,updated_time,parent_id&order_by=updated_time&order_dir=DESC&limit=10"

Get all notebooks (flat list)

curl -s "http://localhost:${JOPLIN_PORT:-41184}/folders?token=$JOPLIN_TOKEN&fields=id,title,parent_id"

Pagination

All list endpoints return paginated results. The response includes:

{
  "items": [...],
  "has_more": true
}

If has_more is true, fetch the next page by adding &page=2, &page=3, etc. Default page size is 100. You can request up to 100 items per page with &limit=100.

To collect all results, loop until has_more is false.

Common Fields

Note fields

id, title, body, parent_id, is_todo, todo_completed, todo_due, source_url, created_time, updated_time, markup_language (1=Markdown, 2=HTML)

Notebook fields

id, title, parent_id, created_time, updated_time

Tag fields

id, title, created_time, updated_time

Resource fields

Error Handling

• 403: Invalid or missing token — check $JOPLIN_TOKEN
• 404: Item not found — verify the ID
• Connection refused: Joplin is not running or Web Clipper is disabled. Instruct user to enable it in Joplin: Tools → Options → Web Clipper → Enable Web Clipper Service.
