We suggest you read the following contributing guide we've created before submitting: https://github.com/vercel/ai/blob/main/CONTRIBUTING.md --> ## Background Splits up vercel#5972 into package changes and updates to examples. ## Summary Moves capabilities validation downstream to the request level instead of the method level. This PR adds a new private `assertCapability` method called at the request level. This means our custom, lightweight client defaults strict mode to true for tool listing and tool calling. ## Verification <!-- For features & bugfixes.

…mable HTTP transport usage (vercel#5972) ## Background The current experimental MCP client already supports the new HTTP transport through the custom transport option (over passing in a config). ## Summary Updates documentation to illustrate usage of the new Streamable HTTP Transport with `experimental_createMCPClient` for tool conversion. As of now, `experimental_createMCPClient` is only used in the AI SDK as a way to fetch and call MCP server tools; for this reason, we are **not** adding support for Session Management or Resumable Streams - which are new features supported by the new HTTP transport. Examples have been updated to illustrate basic usage, and a new Next.js example has been added to illustrate setting up a **stateless** MCP **server** to be used with `useChat` and `streamText`. ## Tasks <!-- This task list is intended to help you keep track of what you need to do. Feel free to add tasks and remove unnecessary tasks as needed. Please check if the PR fulfills the following requirements: --> - [x] Tests have been added / updated (for bug fixes / features) - [x] Documentation has been added / updated (for bug fixes / features) - [ ] A _patch_ changeset for relevant packages has been added (for bug fixes / features - run `pnpm changeset` in the project root) - [x] Formatting issues have been fixed (run `pnpm prettier-fix` in the project root) ## Future Work Given the deprecation of the SSE transport, we should likely deprecate on our end as well. We should consider fully deprecating native support for transports (e.g. our custom `stdio` transport), and enforcing users to always pass in a custom transport to limit need for maintenance on our end. ## Related Issues Fixes vercel#5984

## Background This resolves an issue a user ran into: vercel#6041 ## Summary Aligned openai provider with openai-compatible
## Background This pull request adds the ability for clients to resume an ongoing chat generation stream after a network disconnect. ## Summary This pull request adds support for the `useChat` hook to resume an ongoing chat generation stream by exposing `experimental_resume()` that can be called by any client, typically during the initial mount of the hook. The `experimental_resume` function makes a `GET` request to the api endpoint you've initialized the hook with (or `/api/chat` by default) and streams the contents of the stream if it is active or fails silently if it has ended. In order for `experimental_resume` to work as intended, it requires the usage of the [`resumable-stream`](https://www.npmjs.com/package/resumable-stream) package for stream creation and a redis instance for the package to manage the pub/sub mechanism. ## Verification An example has been added at `examples/next-openai/app/use-chat-resume` to test the feature. Follow the following steps to test it end-to-end: 1. Run the development server 2. Navigate to `http://localhost:3000/use-chat-resume` 3. Send a message that will have a longer generation duration, example "Write an essay about Michael Jordan" 4. Once the generation starts, click the chat id above to open the conversation in a new tab 5. Verify the stream gets resumed ## Tasks - [x] Tests have been added / updated (for bug fixes / features) - [x] Documentation has been added / updated (for bug fixes / features) - [x] A _patch_ changeset for relevant packages has been added - [x] Formatting issues have been fixed (run `pnpm prettier-fix` in the project root) --------- Co-authored-by: Lars Grammel <[email protected]>

Background
When dealing with chat message persistence, it is certainly helpful if the server and client have similar representations of a message, most importantly the key/identifier/id being the same. The id of a message is a bit of a difficult concept due to the message being an aggregation of activities from an AI model and tool executions where each component has an id.
In vercel ai, the server message id comes from the first step part, but the client message id comes from the last step part. The messages on the client get their ids in processChatResponse, on the server in appendResponseMessages. The server chooses the id from the first message part. The client seems to attempt to do this, but fails because the logic doesn't fail to prevent the id from being overridden.
#4845
Summary
I fixed the client processChatResponse to keep the message id from the first step part even as more step parts come in.
Verification
I tested with a variety of ai multi-step responses.
