stack

List every plugin, skill, MCP, agent, command, and hook installed for Claude Code, Claude Desktop, Codex, and Cursor on this machine.

A single read-only command that answers "what is actually installed on this machine, across every coding-agent tool I use, and at what version?" Inspired by ccusage.

Why

The agentic-CLI surface has gotten wide. On one machine you can have:

• Claude Code — plugins, skills (user / project / bundled-in-plugin), MCPs (user, project, plugin), agents, slash commands, hooks, settings overlays.
• Claude Desktop — a separate MCP config and DXT extensions.
• Codex — plugins via marketplace, hooks.
• Cursor — MCPs, hooks.
• Project overlays — .claude/, .mcp.json, CLAUDE.md, AGENTS.md.

stack walks all of those locations and renders a compact, table-style inventory with versions, scopes, and sources. It never writes anything.

Install

No install needed:

npx @woosal1337/stack
# or
bunx @woosal1337/stack

To install globally as the stack command:

npm install -g @woosal1337/stack
stack

Running straight from the repo also works: bunx github:woosal1337/stack.

Works on macOS, Linux, and (experimentally) Windows — Claude Desktop config paths resolve per platform.

Usage

stack                       # full inventory, grouped by tool
stack --tool claude-code    # one tool only
stack --kind mcp            # MCPs across all tools
stack --kind skill --scope user
stack --search compound     # substring match against name + description
stack --versions-only       # tool/kind/name@version, one per line
stack --json                # machine-readable
stack --doctor              # surface warnings only
stack --no-project          # skip $PWD overlay

What it scans

| Tool | Locations | |---|---| | Claude Code | ~/.claude/plugins/installed_plugins.json, ~/.claude/skills/, ~/.claude/agents/, ~/.claude/commands/, ~/.claude/settings.json, ~/.claude.json (mcpServers + per-project), plugin-bundled agents/, commands/, and skills/ inside ~/.claude/plugins/cache/<marketplace>/<plugin>/<version>/ | | Claude Desktop | claude_desktop_config.json and Claude Extensions/ under ~/Library/Application Support/Claude (macOS), %APPDATA%\Claude (Windows), or $XDG_CONFIG_HOME/Claude (Linux) | | Codex | ~/.codex/config.toml (plugins + marketplaces), ~/.codex/skills/, ~/.codex/hooks.json | | Cursor | ~/.cursor/mcp.json, ~/.cursor/hooks.json | | Project overlay (current working directory) | .mcp.json, .claude/, CLAUDE.md, AGENTS.md |

Version resolution order per item: manifest .version → version segment in install path → marketplace lockfile → unknown.

Non-goals

• Not a package manager. stack never installs, removes, updates, or modifies anything. Read-only by design.
• Not a config validator. It surfaces what is installed, not whether it's wired up correctly. Use claude mcp list or per-tool diagnostics for that.
• No telemetry. No network calls except an optional local git rev-parse for version resolution.
