ViennaPlugin Development

Build entities, integrations, and drawer panels for the Vienna desktop app.

Entity System

Define custom entity types with URI addressing, display metadata, and caching — automatically exposed via GraphQL and MCP through integration schema callbacks.

Integrations

Connect to external APIs with typed clients, OAuth, and GraphQL schema extensions. Define queries, mutations, and entity handlers in one place.

Plugin Canvases

Extend the app UI with nav-sidebar, drawer, and menu-bar canvases. Plugin components render in named slots with typed props and host API access.

API Reference

Auto-generated reference for the Plugin SDK — definition factories, URI utilities, React hooks, types, registries, and testing.
