plgnz

Open-source installer and doctor for agent plugins (Agent Plugins / OpenPlugin spec 1.0.0) and MCP configs — Claude Code, Codex, Cursor, Kimi, and more.

npx plgnz add <plugin-dir-or-marketplace-or-git-url>  # native plugin stores
npx plgnz doctor                          # dead commands, shadowed entries, stale installs
npx plgnz pin                             # absolute command paths for GUI hosts
npx plgnz update                          # re-add from the recorded source, re-pin

pin rewrites a plugin's bare stdio command to the absolute path it resolves to right now — a macOS GUI host like Cursor starts with no shell PATH, so a spec-valid bare command never launches there. update is an idempotent re-add from the source recorded in state.json, plus the pins that install carried. Both refuse rather than guess, and neither will touch a plugin this tool did not install. Details: docs/pin-and-update.md.

Why another tool: npx plugins is closed-source and its Cursor target does not install into Cursor; nothing in the ecosystem checks that an installed plugin still works. See docs/research/.

The npx command requires Node.js/npm and Bun on PATH; the CLI runs under Bun. add accepts a local plugin or marketplace directory as well as a Git URL. Native plugin targets currently include Claude Code, Codex, Kimi, Cursor, OMP, Hermes, Grok, DCode, and ZCode CLI. Run plgnz targets --all to see supported and unsupported capabilities for each host; standalone skill distribution is outside this CLI's scope.
