Your VRChat projects, in one place

ALCOMD3 helps creators handle the routine work around VRChat Unity projects without juggling project folders and package files by hand.

• Manage projects: create, register, copy, back up, and restore projects from one desktop app.
• Control VPM packages: browse repositories and install, remove, or update the packages used by each project.
• Work with familiar links: open VCC-compatible vcc:// links and manage repositories from the same workflow.
• Make it yours: use a Material Design 3-style interface with light, dark, and customizable themes.
• Bring your own AI tools: optionally give MCP-capable clients scoped local access to ALCOMD3 projects, packages, repositories, and logs.

Get started

1. Visit the ALCOMD3 website and choose the stable or beta channel.
2. Download the package for your operating system and install or launch it.
3. Add an existing VRChat Unity project or create a new one, then manage its packages, repositories, and backups from ALCOMD3.

Official builds are available for Windows x64, macOS on Apple Silicon, and Linux x64. You can also browse every published version on GitHub Releases.

When self-updating is available, ALCOMD3 checks for signed updates at startup by default, downloads an available update, and installs it before the next launch. This behavior can be disabled in Settings.

Optional local MCP integration

ALCOMD3 can connect MCP-capable AI clients to selected project, repository, package, environment, activity, and technical log data. It also provides a limited set of project and package operations.

MCP is disabled by default. When enabled, it uses a bearer-authenticated loopback-only Streamable HTTP endpoint and private local IPC. It never listens on a LAN or public network address. Manual client setup remains the default; Windows users can optionally let the MCP page configure Codex. See the MCP guide for setup, available tools, and permission boundaries.

Project and community

ALCOMD3 originated from ALCOM/vrc-get and is now maintained as an independent open-source project. It is not an official product of VRChat or VCC.
