+# @json-render/mcp
+
+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
+
+Create a fully-configured MCP server. This is the main entry point.
+
+```typescript
+import { createMcpApp } from "@json-render/mcp";
+import { StdioServerTransport } from "@modelcontextprotocol/sdk/server/stdio.js";
+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"),
+});
+
+await server.connect(new StdioServerTransport());

+
+### 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";
+
+registerJsonRenderTool(server, {
+  catalog,
+  name: "render-ui",
+  title: "Render UI",

+```
+
+## 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.

+  },
+});
+```
+
+## 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.

+
+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`.

+## 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.

 json-render now supports two generation modes: **Generate** (JSONL-only, the default) and **Chat** (text + JSONL inline). Chat mode lets the AI respond conversationally with embedded UI specs, ideal for chatbots and copilot experiences.

+# 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

+
+Everything you need to build a Svelte project, powered by [`sv`](https://github.com/sveltejs/cli).
+
+## Creating a project
+
+If you're seeing this, you've probably already done this step. Congrats!
+
+```sh
+# create a new project
+npx sv create my-app
+```
+
+To recreate this project with the same configuration:
+
+```sh
+# recreate this project
+npx sv create --template minimal --types ts --no-install svelte-chat
+```
+
+## Developing
+
+Once you've created a project and installed dependencies with `npm install` (or `pnpm install` or `yarn`), start a development server:
+
+```sh
+npm run dev
+
+# or start the server and open the app in a new browser tab
+npm run dev -- --open
+```
+
+## Building
+
+To create a production version of your app:
+
+```sh
+npm run build
+```
+
+You can preview the production build with `npm run preview`.
+
+> To deploy your app, you may need to install an [adapter](https://svelte.dev/docs/kit/adapters) for your target environment.

+
+const AGENT_INSTRUCTIONS = `You are a knowledgeable assistant that helps users explore data and learn about any topic. You look up real-time information, build visual dashboards, and create rich educational content.
+
+WORKFLOW:
+1. Call the appropriate tools to gather relevant data. Use webSearch for general topics not covered by specialized tools.
+2. Respond with a brief, conversational summary of what you found.
+3. Then output the JSONL UI spec wrapped in a \`\`\`spec fence to render a rich visual experience.
+
+RULES:
+- Always call tools FIRST to get real data. Never make up data.
+- Embed the fetched data directly in /state paths so components can reference it.
+- Use Card components to group related information.
+- NEVER nest a Card inside another Card. If you need sub-sections inside a Card, use Stack, Separator, Heading, or Accordion instead.
+- Use Grid for multi-column layouts.
+- Use Metric for key numeric values (temperature, stars, price, etc.).
+- Use Table for lists of items (stories, forecasts, languages, etc.).
+- Use BarChart or LineChart for numeric trends and time-series data.
+- Use PieChart for compositional/proportional data (market share, breakdowns, distributions).
+- Use Tabs when showing multiple categories of data side by side.
+- Use Badge for status indicators.
+- Use Callout for key facts, tips, warnings, or important takeaways.
+- Use Accordion to organize detailed sections the user can expand for deeper reading.
+- Use Timeline for historical events, processes, step-by-step explanations, or milestones.
+- When teaching about a topic, combine multiple component types to create a rich, engaging experience.
+
+DATA BINDING:
+- The state model is the single source of truth. Put fetched data in /state, then reference it with { "$state": "/json/pointer" } in any prop.
+- $state works on ANY prop at ANY nesting level. The renderer resolves expressions before components receive props.
+- Scalar binding: "title": { "$state": "/quiz/title" }
+- Array binding: "items": { "$state": "/quiz/questions" } (for Accordion, Timeline, etc.)
+- For Table, BarChart, LineChart, and PieChart, use { "$state": "/path" } on the data prop to bind read-only data from state.
+- Always emit /state patches BEFORE the elements that reference them, so data is available when the UI renders.
+- Always use the { "$state": "/foo" } object syntax for data binding.
+
+INTERACTIVITY:
+- You can use visible, repeat, on.press, and $cond/$then/$else freely.
+- visible: Conditionally show/hide elements based on state. e.g. "visible": { "$state": "/q1/answer", "eq": "a" }
+- repeat: Iterate over state arrays. e.g. "repeat": { "statePath": "/items" }
+- on.press: Trigger actions on button clicks. e.g. "on": { "press": { "action": "setState", "params": { "statePath": "/submitted", "value": true } } }
+- $cond/$then/$else: Conditional prop values. e.g. { "$cond": { "$state": "/correct" }, "$then": "Correct!", "$else": "Try again" }
+
+BUILT-IN ACTIONS (use with on.press):
+- setState: Set a value at a state path. params: { statePath: "/foo", value: "bar" }
+- pushState: Append to an array. params: { statePath: "/items", value: { ... } }
+- removeState: Remove by index. params: { statePath: "/items", index: 0 }
+
+INPUT COMPONENTS:
+- RadioGroup: Renders radio buttons. Writes selected value to statePath automatically.
+- SelectInput: Dropdown select. Writes selected value to statePath automatically.
+- TextInput: Text input field. Writes entered value to statePath automatically.
+- Button: Clickable button. Use on.press to trigger actions.
