What is using-joplin?

A guide for working with Joplin, a note-taking application, through its local data connection. It explains how to check the connection and choose workflows for notes, notebooks, tags, files, and revisions.

Use it to create, read, update, organise, search, tag, and manage Joplin notes and their attached resources.

It helps avoid failed requests and common mistakes when an agent works with Joplin data.

Install

Getting it into your agent

One page per mod, every tool's command on it. A separate URL per tool would split the same page into five that compete with each other.

Any agent

npx skills add sohampatwardhan/Agentic-Joplin --skill using-joplin

Clone the repo

git clone --depth 1 https://github.com/sohampatwardhan/Agentic-Joplin

Made for: Claude Code.

Or install agentic-joplin, the plugin that ships this one along with the rest of its 4 skills, 1 MCP server.

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.

Model	Per session	Once invoked
Fable 5.1	$0.00056	$0.01209
Opus 5.5	$0.00022	$0.00484
Sonnet 5.5	$0.00011	$0.00242
Haiku 4.5	$0.00006	$0.00121

Security

Grade A, and why

using-joplin scanned grade A with 0 findings 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 5d ago.

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.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

How it starts

The opening of the file, as written. The whole thing — 91 lines — stays where its author put it; the contents beside it link to each section on GitHub.

Using Joplin

These tools talk to a running Joplin desktop app through its Data API (the Web Clipper service). Tool names below are the base names; your client may expose them namespaced (e.g. mcp__joplin__create_note).

Before anything else: check the connection

Call ping first. If it does not return available, tell the user to:

Open the Joplin desktop app.
Enable the Web Clipper service (Options > Web Clipper).
Make sure the API token is configured (the plugin reads JOPLIN_TOKEN).

Do not keep retrying other tools if ping fails — surface the fix instead.

What's available

Area	Tools
Notes	`create_note`, `get_note`, `update_note`, `delete_note`, `list_notes`
Notebooks	`get_notebook`, `list_notebooks`, `create_notebook`, `update_notebook`, `delete_notebook`
Tags	`get_tag`, `list_tags`, `create_tag`, `update_tag`, `delete_tag`, `tag_note`, `untag_note`
Search	`find_notes`
Resources	`attach_resource`, `get_resource`, `update_resource`, `delete_resource`, `list_note_resources`
Revisions	`list_note_revisions`, `delete_note_revisions`
System	`ping`

Conventions and pitfalls

Resolve names to IDs first. Every tool takes IDs, not titles. Use list_notebooks (returns a flat list plus a nested tree), find_notes, or list_tags to look up an ID before acting on it.
Deletes trash by default. delete_note / delete_notebook move to the trash. Passing permanent: true is irreversible — confirm with the user before a permanent delete.
Lists can be truncated. List/search results include a truncated flag; if it is true, narrow the query (by notebook/tag) or pass a smaller limit rather than assuming you saw everything.
Attaching a resource rewrites the note body. attach_resource reads the note and writes an appended link back as a second call — avoid interleaving other edits to the same note around it.
Notes have a format. A note is Markdown or HTML; get_note returns a format field, and create_note/update_note take a format (markdown default, or html). HTML is stored faithfully — you do not need to think about Joplin's internal markup fields.

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.
