@maxhealth.tech/prefabDeclarative UI for MCP Apps

115+ components, reactive state, zero-framework renderer — from TypeScript or Python.

🧩

115+ Components

Layout, typography, data tables, charts, forms, interactive tabs, accordions, dialogs — all declarative JSON.

⚡

Template expressions like {{ count + 1 }} with 20+ pipes. Auto-update on state changes, no framework needed.

🔌

display() wraps your component tree as an MCP tool result. First-class CallTool, SendMessage, and UpdateContext actions.

🌐

Vanilla DOM renderer as a single IIFE script tag. Zero dependencies, zero build step for the browser.

🤖

autoTable, autoChart, autoForm, autoMetrics — generate full UIs from raw data in one call.

🐍

Same $prefab v0.2 wire protocol as the Python prefab-ui. TS is a superset — chart formatting extensions are TS-only.
