MooTool

Handy desktop toolset for developers.

About

Hi! Thanks for using MooTool. “Moo” is named after my daughter.

I keep building and improving MooTool to support my own day-to-day development work.

Fewer Java developers build with Swing nowadays, but I still enjoy it. So in every bit of free time, I kept working on this project. I finally shipped something, though many similar tools exist on the web.

Hope you enjoy using it as much as I enjoyed building it.

Supported platforms

Windows • Linux • macOS. Target platforms and current status are listed below; editions under development have not completed release acceptance on every target platform.

Product lines

MooTool now has 7 independent product lines, each with its own code, build, version, installation identity, data, and update channel. They can be installed side by side and evolve independently. Version numbers are specific to each product; see its documentation for feature coverage.

MooTool Next Electron	Electron, Vite, React, TypeScript; the currently recommended desktop edition.	Windows / Linux / macOS	Stable: Download 1.3.6
MooTool Java	Java, Swing; the original desktop edition, still maintained.	Windows / Linux / macOS	Stable: Download 1.8.7 · Gitee mirror
MooTool Next Tauri	Tauri 2, Rust, React, TypeScript; 25 tools with independent storage and updates.	Windows / Linux / macOS	Release candidate: Download 0.1.0-rc.2
MooTool Next macOS Native	SwiftUI, AppKit, system frameworks; native workspaces, JSON vault, quick notes, and image attachments.	macOS 14+	Pre-release: Download 0.8.0
MooTool Next Flutter	Flutter, Dart; tools and desktop channels are implemented, with platform acceptance and some capabilities still in progress.	Windows / Linux / macOS	0.1.0 development build; local run and unsigned packaging scripts available.
MooTool Next Compose	Kotlin, Compose Multiplatform Desktop; multiple tools, quick notes, and backup/restore implemented.	Windows / Linux / macOS	0.1.0 development build; local macOS app-image build verified, with its own JVM runtime.
MooTool Next FX	OpenJDK, OpenJFX (JavaFX); application shell, JSON vault, encoding/decoding, and regex tools implemented.	Windows / Linux / macOS	0.1.0-SNAPSHOT early development build; local macOS app-image packaging implemented.

Follow the product links for source code or the product README, including development setup, running, packaging, and acceptance notes. The current macOS native product lives in next-macos-native/; macos/ contains the early SwiftUI prototype.

Use MooTool with AI (Next Electron)

MooTool Next Electron 1.3.6 lets local AI clients use MooTool through MCP or a standalone Skill. Tools use the bundled runtime, so no separate Node.js installation is needed and calls work with the MooTool window closed.

Client	One-click integration
Codex	MCP, Skill, or both
Claude Code	MCP, Skill, or both
Cursor	MCP

• 11 tools: JSON formatting and JSONPath queries, encoding/decoding, timestamps, text diffs, hashes, UUIDs, plus search and read tools for Quick Notes and JSON documents.
• Installation management: preview generated configuration, test the connection, inspect installation status, repair/update, and uninstall. Existing configuration is backed up; conflicting user edits are reported and preserved.
• Read-only document access: off by default, with a separate grant for each vault. Disabling access takes effect on the next call; moving a vault revokes access. Reads are paginated and exclude hidden files, symbolic links and files ignored by the vault root’s .gitignore.

To get started:

1. Install MooTool at a permanent location: macOS Applications, the Windows installer, or Linux deb. AppImage and Windows portable runtimes cannot be registered for one-click AI integration.
2. Open Settings → AI integration, choose the client and integration mode, review the preview, then click Install in one click.
3. Restart the AI client or reload its MCP / Skills, enabling the tools if prompted. Try “Use MooTool to sort the keys in this JSON.”
4. For saved documents, enable Allow reading Quick Notes or Allow reading JSON documents in the same settings page, then ask the AI to search the corresponding vault.

Other local stdio MCP clients can use Copy MCP configuration. See the AI integration guide for installation paths, limits, standalone Skill usage and verification records.

Screenshots

If MooTool helps you, consider supporting the evenings and weekends spent building it — your appreciation keeps me motivated.

Developer notes

See the multi-product release conventions for version, Git tag, GitHub Release, Latest, and CI isolation rules.

Each product has an independent project. Read its README linked in the product table and work in the corresponding directory. The JDK, IntelliJ IDEA, Maven, and packaging instructions below apply only to MooTool Java at the repository root.

Minimum JDK: 25
Before you start, configure IntelliJ IDEA as shown below, then run maven clean:

Packaging & CI

Packaging JDKs can be downloaded and cached locally:

• JDK archives: downloads/jdks/
• Extracted JDKs: jdks/<os>/<arch>/home

The download script uses Eclipse Temurin 25 and reuses only a matching JDK. Add --force to replace an older cache.

Prepare local packaging JDKs

python3 scripts/prepare_jdks.py --targets mac-x64
python3 scripts/prepare_jdks.py --targets mac-arm64
python3 scripts/prepare_jdks.py --targets windows-x64
python3 scripts/prepare_jdks.py --targets linux-x64

Resolve all download targets:

python3 scripts/prepare_jdks.py --targets all --resolve-only

Local package commands

Default mvn clean package uses your current JDK and builds a macOS universal package.

Profiles mac-intel, mac-apple-silicon, windows-x64, and linux-x64 validate cached JDKs under jdks/ during validate; run scripts/prepare_jdks.py first or the build fails fast.

Package for a specific platform using cached JDKs:

mvn clean package -Pmac-intel -Dmaven.test.skip=true
mvn clean package -Pmac-apple-silicon -Dmaven.test.skip=true
mvn clean package -Pwindows-x64 -Dmaven.test.skip=true
mvn clean package -Plinux-x64 -Dmaven.test.skip=true

Output directories:

• Default: target/
• Intel Mac: target/mac-intel/
• Apple Silicon Mac: target/mac-apple-silicon/
• Windows x64: target/windows-x64/
• Linux x64: target/linux-x64/
