cmm — Claude Marketplace Manager

A CLI tool for managing plugin versions and structure in a Claude Code plugin marketplace.

Install

npm install -g @aeriondyseti/claude-marketplace-manager

Or run without installing:

npx -y @aeriondyseti/claude-marketplace-manager <command>

Commands

cmm init

Interactively initialize a new marketplace in the current directory. Prompts for name, owner, and whether it's a single-plugin or multi-plugin marketplace.

cd my-marketplace-repo
cmm init

cmm add <plugin-name>

Scaffold a new plugin inside the current marketplace and optionally register it in marketplace.json.

cmm add my-new-plugin

Creates:

my-new-plugin/
├── .claude-plugin/plugin.json
├── skills/
├── hooks/
├── agents/
└── mcp.json

cmm bump <type> [plugin-name]

Bump a plugin's version and the marketplace's version, then commit and tag.

# From inside a plugin directory
cmm bump patch

# From the marketplace root
cmm bump minor my-plugin
cmm bump major my-plugin --dry-run

Bump types: patch (bug fix), minor (new feature), major (breaking change).

The --dry-run flag previews changes without writing or committing anything.

cmm status

Show all plugins in the current marketplace and their versions.

Marketplace structure

cmm expects a monorepo-style marketplace: the repo itself is the marketplace, and each plugin lives in its own subdirectory.

my-marketplace/
├── .claude-plugin/
│   └── marketplace.json      ← marketplace registry
├── plugin-one/
│   ├── .claude-plugin/
│   │   └── plugin.json
│   ├── skills/
│   └── mcp.json
└── plugin-two/
    ├── .claude-plugin/
    │   └── plugin.json
    └── ...

For single-plugin marketplaces, the plugin and marketplace share the same root — marketplace.json and plugin.json both live in .claude-plugin/.

How versioning works

• Each plugin has its own semantic version in plugin.json.
• The marketplace has its own version in marketplace.json under metadata.version.
• Running cmm bump increments both — the plugin version and the marketplace version — by the specified level (patch, minor, or major).
• Other plugins in the marketplace are not bumped.
• A git commit and tag (v<new-marketplace-version>) are created automatically.
