MCP App StoreMCP App Storepkgx provides an interface to fetch and run open-source CLI tools on-the-fly without installing them globally. It solves versioning and availability problems by temporarily injecting tools into the environment for immediate execution.
Activate when you need to run a CLI tool once (no install), test a specific tool version, or add temporary tooling to a session without altering system PATH or configuration. Not intended for permanent installs.
Useful for agents that can execute shell commands or orchestrate tooling (Copilot/Codex-like environments, CLI-capable assistants).
The pkgx skill is listed as a universal tool runner for executing open-source CLI tools on demand, but the source SKILL.md file is no longer available at the listed GitHub URL (404). No skill body was retrievable and no scripts were bundled. The skill cannot be evaluated or used in its current state — the source appears to have been removed or restructured from the x-cmd/skill repo.
skill_md_body is null and the raw GitHub URL returns 404. The x-cmd/skill repo no longer contains a pkgx directory. This skill entry in the DB appears stale — the source was likely removed. Without any accessible content, only the DB metadata (description, tags) was available for review. Low scores reflect the complete absence of auditable content, not inherent problems.
