## What kind of change does this PR introduce?
Feature — a new UI Library block. Stacked on #49573 (already in main)
Fixes AI-1064
## What is the new behavior?
Adds `headless-app-tanstack`: customers sign in, authorize an MCP
client, and use the product through agent tool calls. It composes the
existing Password-Based Auth, OAuth Consent, and MCP Server blocks.
- `/agents` provides a copyable connection prompt, lists OAuth
authorizations, and lets customers revoke access.
- The shared MCP runtime exposes `whoami` plus example task CRUD tools.
Tools use the caller's Supabase client, with database grants and RLS
enforcing ownership.
- A root-level `supabase/` directory supplies local Auth/OAuth
configuration, a declarative tasks schema, and Edge Function files,
including `.env.example`.
- Docs cover local setup, signing keys, migrations, environment
configuration, deployment, and extending the tools.
`/example/headless-app` previews the sign-in, consent, connect, and
connected states.
Shared block fixes make a fresh install work:
- Explicit public URL resolution fixes OAuth discovery in local Edge
Runtime when middleware runtime detection fails. Both external OAuth
access tokens and ordinary authenticated app session tokens remain
supported; embedded agents do not need an additional consent flow.
- Registry targets keep backend files outside `src/`, and generated
consumer routes omit source-only TypeScript suppressions.
- Signup respects `auth.email.enable_confirmations`; sign-in/signup
preserve the return destination. Missing consent IDs retain the existing
error state without serializing `null` into the URL.
## How to test
Use the UI Library on **staging** and follow the block pages'
instructions.
1. Open the **Headless App** block page for TanStack Start. Install it
into a fresh app and follow the setup instructions through connecting an
MCP client.
2. Sign up, open `/agents`, and use the connection prompt to authorize a
client. Call `whoami`, then create, list, update, and delete a task.
3. Confirm the client appears on `/agents`. Revoke access and verify it
disappears and token refresh fails. An existing access token can
continue working until it expires.
4. Follow the **MCP Server** block page's embedded-agent instructions
using an authenticated app session. Confirm tools work without another
OAuth consent flow and `whoami` returns `client_id: null`.
5. With a second user, confirm each user can only access their own
tasks. Check that signup behaves correctly for the configured
email-confirmation setting.
6. Check the Headless App preview states and run the installed app's
typecheck and production build.
## Validation performed
Fresh local installation and browser/SDK verification passed: 26 live
MCP/Data API checks, 10 Deno tests, and 7 connection-page component
tests. Also passed UI Library typecheck, targeted lint,
registry/Markdown builds, and fresh consumer typecheck/production build.
Both OAuth and ordinary app session authentication were exercised.
Hosted deployment and consuming the confirmation-email link were not
tested.

Introduces a new OAuth consent block in preparation for offering more
MCP focused blocks that require authentication and consent. The general
approach for this is to decouple consent block from authentication block
but provide guidance on how to use both. The alternative is to add auth
as a dependency to consent but apps may already have their own
authentication UI / flows.
The block is also positioned as a general OAuth Consent vs MCP Consent
as it can be put to use for other use cases outside of MCP on projects
who want to make use of the OAuth 2.1 Server offering.
A couple of changes outside of the block itself were required:
- Updated the Auth blocks to allow for a `next` param to redirect users
to after signing in
- Updated middleware so next param is correctly passed through to sign
in
## How to test
Requires Docker and a Supabase CLI recent enough to support
`[auth.oauth_server]` (verified on 2.109.0 / GoTrue v2.192.0).
### 1. Local Supabase with the OAuth server enabled
In your `supabase/config.toml`, edit the existing `[auth.oauth_server]`
section — `supabase init` already writes one, and adding a second fails
with `table oauth_server already exists`:
```toml
[auth.oauth_server]
enabled = true
authorization_url_path = "/oauth/consent"
allow_dynamic_registration = true
```
Set `site_url` to wherever your test app runs (e.g.
`http://localhost:3100`), then `supabase start`. Grab the API URL and
publishable key from `supabase status`.
### 2. A consumer app with the blocks installed
The consent block ships no login route by design, so pair it with an
auth block:
```bash
npx create-next-app@latest consent-test --ts --tailwind --app --yes
```
```bash
cd consent-test && npx shadcn@latest init -d -y && npx shadcn@latest add https://supabase.com/library/r/password-based-auth-nextjs.jsonhttps://supabase.com/library/r/oauth-consent-nextjs.json
```
To test this branch before it deploys, run `pnpm --filter ui-library
dev` and use `http://localhost:3004/library/r/...` instead. If you
changed anything under `registry/default/blocks/oauth-consent/**`, run
`pnpm --filter ui-library build:registry` first — shadcn fetches the
generated `public/r/*.json`, not the source.
Put `NEXT_PUBLIC_SUPABASE_URL` and
`NEXT_PUBLIC_SUPABASE_PUBLISHABLE_KEY` in `.env.local` and start the app
on the port you set as `site_url`.
### 3. Register an OAuth client and start a real authorization request
```bash
curl -s -X POST http://127.0.0.1:54321/auth/v1/oauth/clients/register -H "Content-Type: application/json" -d '{"client_name":"Test Client","redirect_uris":["http://localhost:3100/callback"],"grant_types":["authorization_code"],"response_types":["code"],"scope":"openid profile email"}'
```
Then open the authorize URL in a browser (not curl — you need the
redirect chain and cookies):
```
http://127.0.0.1:54321/auth/v1/oauth/authorize?client_id=<id>&response_type=code&redirect_uri=http://localhost:3100/callback&scope=openid+profile+email&state=xyz&code_challenge=<challenge>&code_challenge_method=S256
```
Auth mints the `authorization_id` and redirects to
`<site_url>/oauth/consent?authorization_id=…`. An MCP client pointed at
your app is an even better driver, since that's the real consumer shape.
### 4. Cases to walk
| Case | Expected |
| --- | --- |
| Signed out, hit the authorize URL | Lands on
`/auth/login?next=%2Foauth%2Fconsent%3Fauthorization_id%3D…`; after
login, returns to the consent screen |
| Consent screen | Shows client name, redirect URI, signed-in email, and
requested scopes from `getAuthorizationDetails` |
| Allow access | Redirects to `redirect_uri` with `code` and your
original `state`; the code exchanges at `/oauth/token` for a real access
token |
| Deny | Redirects with `error=access_denied` and your `state` |
| Re-run the same authorize URL after approving | Skips the screen,
straight to callback with a new code |
| Visit `/oauth/consent` with no `authorization_id` | "This page needs
an authorization_id" |
| Stale or bogus `authorization_id` | Error shown, buttons still usable
|
| Double-click Allow | Exactly one `POST
/oauth/authorizations/<id>/consent` |
Test the react, react-router, or tanstack variant the same way if you're
touching them — the hook is duplicated per framework, so a fix in one
doesn't carry.

## Summary by CodeRabbit
* **New Features**
* Added an OAuth 2.1 consent experience with client details, requested
scopes, redirect URI, and approve/deny actions.
* Added OAuth consent examples and registry blocks for Next.js, React,
React Router, and TanStack Start.
* Added OAuth documentation, navigation, and framework support across
the UI library.
* **Bug Fixes**
* Login flows now safely preserve valid same-origin redirect
destinations while rejecting unsafe URLs.
* OAuth routes can handle consent flows before authentication and
redirect safely to sign-in.

This PR introduces a new `RealtimeFlow` component and hook to the UI
library for building collaborative React Flow with Supabase Realtime:
- keeps nodes and edges in sync across multiple connected clients in
real time
- uses Yjs with `@supabase-labs/y-supabase` to propagate flow updates
- supports optional persistence, so a flow can be restored from
previously saved shared state

This PR migrates all tailwind configs in the apps to be CSS configs.
They import a shared CSS Tailwind config from the `config` package
(which in turns imports the old JS config).
The shared JS config will be migrated to CSS in a followup PR.
<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
## Summary by CodeRabbit
* **Chores**
* Centralized Tailwind into a config-driven entrypoint and updated the
app build flow to use the new build step; many apps now import unified
global styles.
* **Style**
* Migrated global styles to a Tailwind v4-style setup, added
project-wide content scanning, consolidated theme imports, standardized
theme tokens (including new --container-site max-width), and added a
small prose utility to remove paragraph margins.

This PR fixes a bug where a user might choose `classic-dark` as a theme
in `studio` but then `docs` and `marketing` apps will look weird.
To test:
- Change the localStorage value of `theme` to `classic-dark`
- Open `www` and `docs` apps, they should look ok
<!-- This is an auto-generated comment: release notes by coderabbit.ai
-->
## Summary by CodeRabbit
* **New Features**
* Added a new "classic-dark" theme option for enhanced visual
customization.
* **Improvements**
* Unified and simplified theme handling across apps for more consistent
behavior.
* Improved system-theme detection and smoother transitions when
switching themes.

This PR migrates the whole monorepo to use Tailwind v4:
- Removed `@tailwindcss/container-queries` plugin since it's included by
default in v4,
- Bump all instances of Tailwind to v4. Made minimal changes to the
shared config to remove non-supported features (`alpha` mentions),
- Migrate all apps to be compatible with v4 configs,
- Fix the `typography.css` import in 3 apps,
- Add missing rules which were included by default in v3,
- Run `pnpm dlx @tailwindcss/upgrade` on all apps, which renames a lot
of classes
- Rename all misnamed classes according to
https://tailwindcss.com/docs/upgrade-guide#renamed-utilities in all
apps.
