Chuk MCP UI

What it does

Chuk MCP UI is a monorepo of 68 single-file HTML views that plug into LLM interfaces through the MCP ext-apps protocol. Each view is built with Vite + vite-plugin-singlefile and communicates with its host model using three channels: pushing UI state into model context, sending events to the host, and responding to model-initiated calls. Views also talk to each other through a shared ViewBus cross-view message bus.

Key features

• 68 pre-built view apps — covering dashboards, Leaflet maps, Chart.js charts, data tables, dynamic forms, and more
• Self-contained HTML files — each view bundles everything it needs; no CDN dependencies at runtime
• ViewBus messaging — cross-view pub/sub bus for composing multi-panel LLM UIs
• Design system included — @chuk/view-ui component library and @chuk/view-shared hooks
• Storybook playground — live catalogue of all views for development and testing
