-Add `AudioRecorder` (`@tanstack/ai-client`) and framework hooks for recording an
-audio message in the browser: `useAudioRecorder` (React/Solid/Vue),
-`createAudioRecorder` (Svelte), and `injectAudioRecorder` (Angular). The
-recording exposes a ready-to-use audio content part (`.part`) for `sendMessage`
-and base64 (`.base64`) for the generation hooks. Native recorder output
-(webm/mp4), no transcoding, no new dependency.
-
-Each hook also returns a reactive `recording` field — the latest resolved
-recording (`AudioRecording | null`), available without awaiting `stop()`. Pass
-`onComplete: (recording) => T | Promise<T>` to transform the output: `stop()`
-then resolves to `T` and `recording` becomes `T | null`. Omitting `onComplete`
-keeps the raw `AudioRecording`.

-Fix `onResult` transform type inference on the generation hooks across every
-framework package — the base generation hook plus `generateImage`,
-`generateAudio`, `generateSpeech`, `generateVideo`, `transcription`, and
-`summarize` (React `use*`, Vue `use*`, Solid `use*`, Svelte `create*`, and
-Angular `inject*`).
-
-The hooks declared the `onResult` transform via a single defaulted type
-parameter inferred from an optional nested property, which TypeScript collapses
-to its default — leaving the callback parameter typed `any` (a hard error under
-`strict`) and never narrowing `result` to the transform's return type. The
-hooks now infer the transform type from the `onResult` return position (a
-covariant inference site that works for an optional nested property), so the
-callback parameter is typed as the raw result and `result` narrows to the
-transform's return type; omitting the transform keeps the raw result type. See
-issue #848.

-Fix `grokSummarize`/`createGrokSummarize` not being assignable to `summarize()`'s
-`adapter` param for any current Grok model (`grok-4.3`, `grok-build-0.1`).
-
-`GrokTextProviderOptions` was declared as an `interface` extending
-`Record<string, unknown>`, giving it an explicit index signature. Under
-`strictFunctionTypes`, the `SummarizeAdapter` constraint is checked
-contravariantly, which requires `object` to be assignable to the provider
-options — but `object` is not assignable to an index-signature type, so the
-check failed (Grok-only; OpenAI's all-optional, no-index-signature options
-passed). The options are now a type-alias intersection matching the OpenAI
-shape, and the text adapter's provider-options constraint is widened to
-`Record<string, any>` to mirror `OpenAITextAdapter`.

-feat: MCP Apps support — render interactive `ui://` widgets served by MCP servers
-
-Adds support for the ratified [MCP Apps](https://modelcontextprotocol.io/extensions/apps/overview) standard, letting MCP server tools return interactive UI widgets that render in the chat.
-
-- **`@tanstack/ai`** — MCP tool results that link a `ui://` resource (via `_meta.ui.resourceUri`) now surface as a new `UIResourcePart` on the assistant `UIMessage` (carried as an AG-UI `CUSTOM` event). The widget never enters model input. The `ui://` resource is read eagerly during the run, fail-soft.
-- **`@tanstack/ai-mcp`** — tool discovery now captures `serverId` + the UI resource link; `MCPClient` gains a public `callTool` and `getInfo()` (returns the client's transport descriptor); `MCPClients` gains `getServers()` (returns all pool entries' descriptors). New `@tanstack/ai-mcp/apps` subpath exports `createMcpAppCallHandler` — a server-side tool-call proxy for interactive widgets that takes the MCP client(s)/pool you already created (`clients: MCPClient | MCPClients | Array<MCPClient | MCPClients>`), reads each client's transport descriptor via `MCPClient.getInfo()` / `MCPClients.getServers()` (pure config, no live socket required), and **reconnects per call** (stateless, serverless-safe by default, same-server allowlist). Also exports an in-memory `McpSessionStore` seam for stateful transports.
-- **`@tanstack/ai-client`** — `createMcpAppBridge`, a framework-agnostic bridge routing widget tool-calls to the call handler, follow-up prompts into the chat, and blocking links unless a handler is supplied.
-- **`@tanstack/ai-react` / `@tanstack/ai-preact`** — a `MCPAppResource` component (new `./mcp-apps` subpath) that renders a `UIResourcePart` via `@mcp-ui/client`'s `AppRenderer` (optional peer dependency), wired to the bridge. Plus a `useMcpAppBridge` hook (main entry) that returns a stable `createMcpAppBridge` for a given `threadId`/`callEndpoint` while always calling the latest `sendMessage`/`onLink`.
-
-Persistence is intentionally out of scope (in-memory seams only); Solid/Vue/Svelte/Angular renderers are deferred (the renderer SDK is currently React-only).

-Forward tool-definition `cacheControl` through the OpenRouter function-tool converter so Anthropic prompt caching of tool definitions works over OpenRouter. Previously `metadata.cacheControl` was dropped before serialization, so the cache breakpoint never reached the wire. The OpenRouter SDK already accepts `cacheControl` on a function tool and remaps it to `cache_control`; this mirrors `convertCustomToolToAdapterFormat` in `@tanstack/ai-anthropic`.

+  `adapter` param for any current Grok model (`grok-4.3`, `grok-build-0.1`).
+
+  `GrokTextProviderOptions` was declared as an `interface` extending
+  `Record<string, unknown>`, giving it an explicit index signature. Under
+  `strictFunctionTypes`, the `SummarizeAdapter` constraint is checked
+  contravariantly, which requires `object` to be assignable to the provider
+  options — but `object` is not assignable to an index-signature type, so the
+  check failed (Grok-only; OpenAI's all-optional, no-index-signature options
+  passed). The options are now a type-alias intersection matching the OpenAI
+  shape, and the text adapter's provider-options constraint is widened to
+  `Record<string, any>` to mirror `OpenAITextAdapter`.

+
+  Adds support for the ratified [MCP Apps](https://modelcontextprotocol.io/extensions/apps/overview) standard, letting MCP server tools return interactive UI widgets that render in the chat.
+  - **`@tanstack/ai`** — MCP tool results that link a `ui://` resource (via `_meta.ui.resourceUri`) now surface as a new `UIResourcePart` on the assistant `UIMessage` (carried as an AG-UI `CUSTOM` event). The widget never enters model input. The `ui://` resource is read eagerly during the run, fail-soft.
+  - **`@tanstack/ai-mcp`** — tool discovery now captures `serverId` + the UI resource link; `MCPClient` gains a public `callTool` and `getInfo()` (returns the client's transport descriptor); `MCPClients` gains `getServers()` (returns all pool entries' descriptors). New `@tanstack/ai-mcp/apps` subpath exports `createMcpAppCallHandler` — a server-side tool-call proxy for interactive widgets that takes the MCP client(s)/pool you already created (`clients: MCPClient | MCPClients | Array<MCPClient | MCPClients>`), reads each client's transport descriptor via `MCPClient.getInfo()` / `MCPClients.getServers()` (pure config, no live socket required), and **reconnects per call** (stateless, serverless-safe by default, same-server allowlist). Also exports an in-memory `McpSessionStore` seam for stateful transports.
+  - **`@tanstack/ai-client`** — `createMcpAppBridge`, a framework-agnostic bridge routing widget tool-calls to the call handler, follow-up prompts into the chat, and blocking links unless a handler is supplied.
+  - **`@tanstack/ai-react` / `@tanstack/ai-preact`** — a `MCPAppResource` component (new `./mcp-apps` subpath) that renders a `UIResourcePart` via `@mcp-ui/client`'s `AppRenderer` (optional peer dependency), wired to the bridge. Plus a `useMcpAppBridge` hook (main entry) that returns a stable `createMcpAppBridge` for a given `threadId`/`callEndpoint` while always calling the latest `sendMessage`/`onLink`.
+
+  Persistence is intentionally out of scope (in-memory seams only); Solid/Vue/Svelte/Angular renderers are deferred (the renderer SDK is currently React-only).

+  audio message in the browser: `useAudioRecorder` (React/Solid/Vue),
+  `createAudioRecorder` (Svelte), and `injectAudioRecorder` (Angular). The
+  recording exposes a ready-to-use audio content part (`.part`) for `sendMessage`
+  and base64 (`.base64`) for the generation hooks. Native recorder output
+  (webm/mp4), no transcoding, no new dependency.
+
+  Each hook also returns a reactive `recording` field — the latest resolved
+  recording (`AudioRecording | null`), available without awaiting `stop()`. Pass
+  `onComplete: (recording) => T | Promise<T>` to transform the output: `stop()`
+  then resolves to `T` and `recording` becomes `T | null`. Omitting `onComplete`
+  keeps the raw `AudioRecording`.

+### Minor Changes
+
+- [#843](https://github.com/TanStack/ai/pull/843) [`c1a8732`](https://github.com/TanStack/ai/commit/c1a87327b4a3463d37158f32ca90184b5fd092bb) - feat: MCP Apps support — render interactive `ui://` widgets served by MCP servers
+
+  Adds support for the ratified [MCP Apps](https://modelcontextprotocol.io/extensions/apps/overview) standard, letting MCP server tools return interactive UI widgets that render in the chat.
+  - **`@tanstack/ai`** — MCP tool results that link a `ui://` resource (via `_meta.ui.resourceUri`) now surface as a new `UIResourcePart` on the assistant `UIMessage` (carried as an AG-UI `CUSTOM` event). The widget never enters model input. The `ui://` resource is read eagerly during the run, fail-soft.
+  - **`@tanstack/ai-mcp`** — tool discovery now captures `serverId` + the UI resource link; `MCPClient` gains a public `callTool` and `getInfo()` (returns the client's transport descriptor); `MCPClients` gains `getServers()` (returns all pool entries' descriptors). New `@tanstack/ai-mcp/apps` subpath exports `createMcpAppCallHandler` — a server-side tool-call proxy for interactive widgets that takes the MCP client(s)/pool you already created (`clients: MCPClient | MCPClients | Array<MCPClient | MCPClients>`), reads each client's transport descriptor via `MCPClient.getInfo()` / `MCPClients.getServers()` (pure config, no live socket required), and **reconnects per call** (stateless, serverless-safe by default, same-server allowlist). Also exports an in-memory `McpSessionStore` seam for stateful transports.
+  - **`@tanstack/ai-client`** — `createMcpAppBridge`, a framework-agnostic bridge routing widget tool-calls to the call handler, follow-up prompts into the chat, and blocking links unless a handler is supplied.
+  - **`@tanstack/ai-react` / `@tanstack/ai-preact`** — a `MCPAppResource` component (new `./mcp-apps` subpath) that renders a `UIResourcePart` via `@mcp-ui/client`'s `AppRenderer` (optional peer dependency), wired to the bridge. Plus a `useMcpAppBridge` hook (main entry) that returns a stable `createMcpAppBridge` for a given `threadId`/`callEndpoint` while always calling the latest `sendMessage`/`onLink`.
+
+  Persistence is intentionally out of scope (in-memory seams only); Solid/Vue/Svelte/Angular renderers are deferred (the renderer SDK is currently React-only).
