Claude Code v2.1.129 ·
Session Plugins from URLs
EntryKind: in v2.1.129,
ChangesSection of the release
What
You can now load a session-only plugin directly from a remote .zip URL.
Usage
claude --plugin-url https://example.com/my-plugin.zip
claude --plugin-url https://example.com/a.zip --plugin-url https://example.com/b.zip
Details
--plugin-url is repeatable, like --plugin-dir.- Claude Code fetches the plugin archive, enforces a maximum archive size, extracts it, and loads it only for the current session.
- If re-fetching fails but a cached copy exists, Claude Code can reuse the cached archive.
/doctor now labels these as Session-only plugins (--plugin-dir / --plugin-url).
Evidence
New CLI option and help text (search for "Fetch a plugin .zip from a URL for this session only (repeatable: --plugin-url A --plugin-url B)")
