+
+MCP Apps integration for json-render. Serve json-render UIs as interactive [MCP Apps](https://modelcontextprotocol.io/docs/extensions/apps) inside Claude, ChatGPT, Cursor, VS Code, and other MCP-capable clients.
+
+## Install
+
+```bash
+npm install @json-render/mcp @json-render/core @modelcontextprotocol/sdk
+```
+
+For the iframe-side React UI, also install:
+
+```bash
+npm install @json-render/react react react-dom
+```
+
+See the [MCP example](https://github.com/vercel-labs/json-render/tree/main/examples/mcp) for a full working example.
+
+## Overview
+
+MCP Apps let MCP servers return interactive HTML UIs that render directly inside chat conversations. `@json-render/mcp` bridges json-render catalogs with the MCP Apps protocol:
+
+1. Your **catalog** defines which components and actions the AI can use
+2. The **MCP server** exposes the catalog as a tool with the spec schema
+3. The **bundled HTML** renders json-render specs inside the host's sandboxed iframe
+4. The AI generates a spec, the host renders it, and users interact with the live UI
+
+## Server API
+
+### createMcpApp
+

+
+```typescript

+import fs from "node:fs";
+
+const server = createMcpApp({
+  name: "My Dashboard",
+  version: "1.0.0",
+  catalog: myCatalog,
+  html: fs.readFileSync("dist/index.html", "utf-8"),

+
+### registerJsonRenderTool
+
+Register a json-render tool on an existing `McpServer`. Use this when you need to add json-render to a server that has other tools.
+
+```typescript
+import { registerJsonRenderTool } from "@json-render/mcp";
+

+
+registerJsonRenderResource(server, {
+  resourceUri: "ui://render-ui/view.html",
+  html: bundledHtml,
+});
+```
+
+## Client API (`@json-render/mcp/app`)
+
+These exports run inside the sandboxed iframe rendered by the MCP host.
+
+### useJsonRenderApp
+
+React hook that connects to the MCP host, listens for tool results, and maintains the current json-render spec.
+
+```tsx
+import { useJsonRenderApp } from "@json-render/mcp/app";
+import { JSONUIProvider, Renderer } from "@json-render/react";

+```
+
+### JSONUIProvider
+
+Combined provider wrapper for state, visibility, validation, and actions.

+  validationFunctions={validationFunctions}
+>
+  <Renderer spec={spec} registry={registry} />
+</JSONUIProvider>
+```
+
+## defineRegistry
+
+Create a typed component registry and action helpers from a catalog.
+
+```tsx
+const { registry, handlers, executeAction } = defineRegistry(catalog, {
+  components: {
+    Card: (renderProps) => <div>{renderProps.children}</div>,
+    Button: (renderProps) => (
+      <button onClick={() => renderProps.emit("press")}>
+        {renderProps.element.props.label as string}
+      </button>
+    ),
+  },
+  actions: {
+    submit: async (params, setState, state) => {
+      // custom action logic
+    },
+  },
+});
+```
+
+## Components
+
+### Renderer
+
+```tsx
+<Renderer spec={spec} registry={registry} loading={false} />
+```
+
+Renders a `Spec` tree using your registry.
+
+### createRenderer
+
+Build an app-level renderer from catalog + components:
+
+```tsx
+const AppRenderer = createRenderer(catalog, {
+  Card: (renderProps) => <div>{renderProps.children}</div>,
+});
+
+<AppRenderer spec={spec} state={{}} onAction={(name, params) => {}} />;
+```
+
+## Hooks
+
+- `useStateStore()`
+- `useStateValue(path)` - returns an accessor
+- `useStateBinding(path)` - returns `[Accessor<T | undefined>, setValue]`
+- `useVisibility()` / `useIsVisible(condition)`
+- `useActions()` / `useAction(binding)`
+- `useValidation()` / `useOptionalValidation()`
+- `useFieldValidation(path, config)` - returns accessor-backed `state`, `errors`, and `isValid`
+- `useBoundProp(value, bindingPath)`
+- `useUIStream(options)`
+- `useChatUI(options)`
+
+## Built-in Actions
+
+`ActionProvider` handles these built-in actions:
+
+- `setState`
+- `pushState`
+- `removeState`
+- `validateForm`
+
+## Component Props
+
+Registry components receive:
+
+```ts
+interface ComponentRenderProps<P = Record<string, unknown>> {
+  element: UIElement<string, P>;
+  children?: JSX.Element;
+  emit: (event: string) => void;
+  on: (event: string) => EventHandle;
+  bindings?: Record<string, string>;
+  loading?: boolean;
+}
+```
+
+Use `emit("event")` to dispatch event bindings. Use `on("event")` to access `EventHandle` metadata (`bound`, `shouldPreventDefault`, `emit`).
+
+## Reactivity Notes
+
+- Keep changing reads in JSX expressions, `createMemo`, or `createEffect`.
+- Avoid props destructuring in component signatures when you need live updates.
+- `StateProvider` and other contexts expose getter-backed values so consumers read live signals.
+- `useStateValue`, `useStateBinding`, and `useFieldValidation` expose reactive accessors; call them as functions.

+# @json-render/svelte
+
+Svelte 5 components, providers, and helpers for rendering json-render specs.
+
+## Installation
+
+<PackageInstall packages="@json-render/core @json-render/svelte" />
+
+Peer dependencies: `svelte ^5.0.0` and `zod ^4.0.0`.
+
+<PackageInstall packages="svelte zod" />
+
+## Components
+
+### Renderer
+
+```svelte
+<Renderer
+  spec={spec}       // Spec | null
+  registry={registry}
+  loading={false}
+/>
+```
+
+Renders a spec with your component registry. If `spec` is `null`, it renders nothing.
+
+### JsonUIProvider
+
+Convenience wrapper around `StateProvider`, `VisibilityProvider`, `ValidationProvider`, and `ActionProvider`.
+
+```svelte
+<JsonUIProvider
+  initialState={{}}
+  handlers={handlers}
+  validationFunctions={validationFunctions}
+>
+  <Renderer {spec} {registry} />
+</JsonUIProvider>
+```
+
+## defineRegistry
+
+Create a typed component registry and action handlers from a catalog.
+
+```typescript
+import { defineRegistry } from "@json-render/svelte";
+
+const { registry, handlers, executeAction } = defineRegistry(catalog, {
+  components: {
+    Card,
+    Button,
+  },
+  actions: {
+    submit: async (params, setState, state) => {
+      // custom action logic
+    },
+  },
+});
+```
+
+`handlers` is designed for `JsonUIProvider`/`ActionProvider`. `executeAction` is an imperative helper.
+
+## Component Props
+
+Registry components receive `BaseComponentProps<TProps>`:
+
+```typescript
+interface BaseComponentProps<TProps> {
+  props: TProps;
+  children?: Snippet;
+  emit: (event: string) => void;
+  bindings?: Record<string, string>;
+  loading?: boolean;
+}
+```
+
+Use `emit("eventName")` to trigger handlers declared in the spec `on` bindings.
+
+## Context Helpers
+
+Use these helpers inside Svelte components:
+
+- `getStateValue(path)` - read/write state via `.current`
+- `getBoundProp(() => value, () => bindingPath)` - write back resolved `$bindState` / `$bindItem` values
+- `isVisible(condition)` - evaluate visibility via `.current`
+- `getAction(name)` - read a registered action handler via `.current`
+- `getFieldValidation(ctx, path, config)` - get field validation state + actions
+
+For advanced usage, access full contexts:
+
+- `getStateContext()`
+- `getActionContext()`
+- `getVisibilityContext()`
+- `getValidationContext()`
+- `getOptionalValidationContext()`
+
+## Streaming
+
+### createUIStream
+
+```typescript
+const stream = createUIStream({
+  api: "/api/generate-ui",
+  onComplete: (spec) => console.log(spec),
+});
+
+await stream.send("Create a login form");
+
+console.log(stream.spec);
+console.log(stream.isStreaming);
+```
+
+### createChatUI
+
+```typescript
+const chat = createChatUI({ api: "/api/chat-ui" });
+await chat.send("Build a settings panel");
+console.log(chat.messages, chat.isStreaming);
+```
+
+## Schema Export
+
+Use `schema` from `@json-render/svelte` when defining catalogs for Svelte specs.

+## Generation Modes
+
+The generation mode values passed to `catalog.prompt()` have been renamed for clarity:
+
+- `"generate"` is now `"standalone"`
+- `"chat"` is now `"inline"`
+
+The old names are accepted as deprecated aliases, so existing code will continue to work. Update when convenient.

+# MCP App Example
+
+A json-render MCP App that serves interactive shadcn/ui-based UIs directly inside Claude, ChatGPT, Cursor, VS Code, and other MCP-capable clients.
+
+## Setup
+
+```bash
+pnpm install
+pnpm build
+```
+
+## Usage
+
+### With Cursor
+
+Add to `.cursor/mcp.json`:
+
+```json
+{
+  "mcpServers": {
+    "json-render": {
+      "command": "npx",
+      "args": ["tsx", "examples/mcp/server.ts", "--stdio"]
+    }
+  }
+}
+```
+
+### With Claude Desktop
+
+Add to `~/Library/Application Support/Claude/claude_desktop_config.json`:
+
+```json
+{
+  "mcpServers": {
+    "json-render": {
+      "command": "npx",
+      "args": ["tsx", "/absolute/path/to/examples/mcp/server.ts", "--stdio"]
+    }
+  }
+}
+```
+
+### HTTP Transport
+
+```bash
+pnpm start
+# Server listens on http://localhost:3001/mcp
+```
+
+### Stdio Transport
+
+```bash
+pnpm start:stdio
+```
+
+## How It Works
+
+1. The Vite build bundles the React app (with shadcn components and `useJsonRenderApp` hook) into a single self-contained HTML file
+2. The MCP server registers a `render-ui` tool with the catalog prompt as its description
+3. When the LLM calls the tool, it generates a json-render spec constrained to the catalog
+4. The host renders the bundled HTML in a sandboxed iframe
+5. The iframe receives the spec via the MCP Apps protocol and renders it with json-render
