scriptscat/scriptcat v1.5.0-beta.1 on GitHub

1.5.0-beta.1 (2026-08-06)

This pre-release highlights two major features — External Access (MCP bridge) and a script recycle bin — officially supports Firefox MV3, adds Korean, Turkish, and Brazilian Portuguese, and fixes a number of GM API, cloud-sync, and editor issues.

🚀 Major New Features

💥 New "External Access (MCP bridge)": a local sctl daemon unifies CLI and MCP-client access; every script read/write is gated by tiered authorization and a human confirmation page with three levels — Deny / Allow / Allow this session — and every operation is audited (#1573) (by @cyfung1031)
💥 Script recycle bin: deleted scripts go to the recycle bin first, with restore (preserving the original data and permissions), permanent delete, and expiry-based auto-cleanup; the retention period is configurable (default 30 days, or never) (#1585) (by @CodFrm)
💥 Official Firefox MV3 support, with improved sandbox/offscreen communication (#1561) (by @cyfung1031)
✨ Add quick site-scope actions to the popup (#1646) (by @CodFrm)
✨ Popup script-list expand count is now configurable, separate from the menu expand count (#1645) (by @CodFrm)
✨ Icon service gains a "disabled" tier to fully turn off favicon fetching (#1637) (by @CodFrm)
✨ Undefined metadata tags now show a warning in the editor (#1608) (by @cyfung1031)
✨ Backup/restore/import completeness: ScriptCat/Tampermonkey/Violentmonkey custom config + settings backup + resource repair (#1554) (by @CodFrm)
