Changelog
The Dungeon Never Sleeps
July 17, 2026
Gelatinous MCP Launches: Let AI Agents Build Your Encounters
- Gelatinous MCP is now live (Beta): connect Claude, Cursor, or any MCP-compatible AI agent to create characters, search spells, build encounters, and manage the roster. Just describe what you want.
- Arrow keys (↑ ↓ ← →) now navigate turns and rounds during combat, with matching arrow icons in the action bar for easy discovery.
- Adding the same monster twice now auto-numbers the copies (Mimic 2, Mimic 3) so your combatant list is always unambiguous.

Clickable Ability Scores, Faster Loading, and Wide Accessibility Improvements
- Click any ability score or saving throw to roll it (right-click for advantage or disadvantage), and the stats panel now shows live HP during encounters
- App data loads faster with longer caching, plus a bounded connection pool to prevent hangs under load
- Screen readers now reliably identify every search field, HP input, turn button, dice field, and remove button

Bug Fixes and Accessibility Improvements
- Auth outages now show a clear retry screen instead of hanging on a blank loading screen
- Screen reader and keyboard accessibility improved across the app
- Deleting a missing spell slot or character spell now returns a proper error instead of a server crash
FAQ
Common Questions
Does this work for systems other than D&D 5e?
Not currently. Gelatinous Vault is built around D&D 5e mechanics. Support for other systems is on the roadmap.
Do I need to create an account to try it?
Yes, but anyone can create a free account and start using the product immediately. Free accounts are limited to one campaign and two encounters.
Will my data be saved on the free plan?
Yes. Your campaigns, encounters, and custom monsters are always saved, regardless of plan tier.
What happens if I cancel my paid plan?
Your account reverts to the free tier and you'll only be able to access your first campaign and first two encounters, but all your data stays put.
Is there a mobile app?
Not at the moment. Gelatinous Vault is a web app, optimized for desktop and tablet. A mobile app is on the longer-term roadmap.
Where does the monster data come from?
Monster data comes from the Wizards of the Coast OGL (Systems Reference Document). You can also create and save fully custom monsters.
