Agentic-Joplin

Tooling that lets coding agents integrate with Joplin, the open-source note-taking app.

The project has three planned pieces:

This repo is an npm-workspaces monorepo; each piece lives under packages/.

MCP server

packages/mcp-server is a from-scratch Model Context Protocol server (TypeScript, stdio transport) that gives an agent full CRUD over Joplin notes, notebooks, tags, and resources, plus search, note revision history, and a connectivity check — 26 tools across 7 groups. It wraps Joplin's local Data API (the REST service exposed by the desktop app's Web Clipper).

Requirements

• Node.js ≥ 20

• Joplin desktop running with the Web Clipper service enabled (Options → Web Clipper), and an API token generated there.

Setup

npm install
npm run build --workspace @agentic-joplin/mcp-server

Then add it to your MCP client (e.g. Claude Code / Claude Desktop) as a stdio server running node packages/mcp-server/dist/index.js, with these environment variables:

Joplin must be running with Web Clipper enabled for any tool call to succeed.

Tool surface

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), and ping.

Notes can be created in Markdown (default) or HTML via a format parameter. See packages/mcp-server/README.md for the full per-tool reference and packages/mcp-server/SMOKE_TEST.md for the manual release checklist.

Agent skills plugin

packages/plugin is a single plugin — valid for both Claude Code and Codex — that bundles the Joplin MCP server with four agent skills (using-joplin hub plus joplin-capturing-notes, joplin-searching-and-updating, joplin-organizing). See packages/plugin/README.md for install steps on each platform.

Development

npm run build   # type-check + compile all workspaces
npm test        # run all workspace unit tests (mocked Data API, no Joplin instance needed)

Design docs live under docs/superpowers/: the design spec and the implementation plan.
