# Settings and appearance

Every setting in one place, searchable with ⌘F. Here is what lives where, and how to make AyCode look the way you like.

## Where things are

## Appearance

*Screenshot: Thirteen colour themes in light and dark, an accent colour and a live preview.*

- Light, dark or system, and thirteen colour themes: AyCode, Graphite, Midnight, Nord, Catppuccin, Tokyo Night, Dracula, Rosé Pine, Solarized, Gruvbox, One Dark, Kanagawa and GitHub. A VS Code theme can be imported.
- Accent colour, higher contrast, corners, fonts for answers and code, text size and chat width.
- Backgrounds (stars, aurora, waves or none), motion (system, reduced, full) and density.
- Diffs in blue and orange instead of green and red, for colour blindness.
- App icon, a translucent sidebar and the companion figure.

## General

- Language (German, English or system), how to send (Enter or ⌘Enter) and the default permission mode.
- Notifications when an agent waits, a number on the Dock icon and a menu bar icon with running agents and remaining quota.
- **Datenschutz-Schleuse** (privacy gate): e-mail addresses, phone numbers, IP addresses, IBANs and known keys leave your computer only as placeholders. The traffic light in the input field shows what would be sent.
- Screensaver (Mac): six designs, from a big clock to a pixel village.

## MCP servers and modules

**MCP servers** gives your agents extra tools. Add your own, test them, paste JSON, or take over the ones found in your agent apps. Decide who gets them: automatically, on click, or only when mentioned with **@**.

**Modules** bundle skills, MCP servers, templates and starter tasks for a field of work, such as bookkeeping or a training report. Public modules must be signed, and you trust a publisher once. Build your own: [Building modules](https://aycode.ai/docs/modules/).

## History

*Screenshot: History: a diary of your day, written by itself. Off until you switch it on.*

When switched on, **Verlauf** notes which app is in front and which chats you had, and your default provider summarises it into a short diary. Passwords and screenshots are never taken, password apps are excluded, and you can pause it for an hour. **Wohin die Zeit ging** shows where your time went, **Stundenzettel** copies a day as Markdown for a timesheet.
