fix(sdk,plugins): plugin stores refuse Redis or SQLite in a browser build - #1037
A browser build of the SDK (create() in a page, WebMCP) has no TCP socket for Redis and no file for SQLite. #1028 made the SDK's own stores refuse them at startup with BrowserStoreUnavailableError, but plugins open their stores themselves, so they never took part. CachePlugin and RememberPlugin on type: 'global-store' took the server's top-level redis, and 'redis' / 'redis-client' built an ioredis client anyway. In a page that store failed on its first call. ApprovalPlugin and ResultHandlesPlugin with storage: { type: 'redis' | 'sqlite' } went through createStorage(), which fell back to memory with a warning, or failed with a connection or module error in production.
One helper for every plugin
The SDK now exports refusePluginStoreInBrowser({ plugin, option, memory }). A plugin calls it where it builds its store, before the store connects:
option names what would open Redis or SQLite. It is undefined when nothing would, and then the helper refuses nothing.
memory names the plugin option that keeps the store in memory.
In runtime === 'browser' (the same getRuntimeContext() check the SDK's own stores use), the helper throws the same BrowserStoreUnavailableError (BROWSER_STORE_UNAVAILABLE). error.stores holds [pluginName, option], and the message reads, for example, A browser cannot open Redis or SQLite: CachePlugin would use type: 'global-store' (set type: 'memory' in place of type: 'global-store'). In any other runtime it does nothing, so Node servers behave as before. Plugins never check for a browser themselves: the check lives in one place, and future plugins get the same refusal with one call.
To describe a plugin's store, the error class takes the memory option of each plugin store as a second, optional constructor argument. BrowserRefusedStore widens to 'tasks' | 'elicitation' | 'questions' | 'jobs' | (string & {}), so a plugin's name fits and the SDK's names still autocomplete. A plugin's own memory option wins over an SDK store of the same name.
Where each plugin refuses
Plugin
Refused in a browser
When
Memory option named
CachePlugin
type: 'global-store' on a Redis top-level redis
at startup, in the store's factory, before new CacheRedisProvider
storage: { type: 'redis' } or { type: 'sqlite' }, unless storageInstance is given (it wins over storage)
in init(), once for the approval store and the webhook ChallengeService
storage: { type: 'memory' }
ResultHandlesPlugin
storage: { type: 'redis' } or { type: 'sqlite' }
in init()
storage: { type: 'memory' }
These stay allowed in a browser: Vercel KV (a top-level redis: { provider: 'vercel-kv' }, or type: 'vercel-kv'), Upstash, Cloudflare KV and storage: { type: 'auto' }. The browser getEnv returns no REDIS_URL, so 'auto' resolves to memory in a page.
The explicit 'redis' / 'redis-client' configs are refused in init() because that is where the plugins already build their Redis provider (useValue). Moving that to startup would change when a Node server connects, and Node must behave as before.
Left open: one refusal at a time
The SDK refuses its own stores early in scope.initialize(), before any plugin's providers are built. The plugins refuse theirs when those providers are built. So a page with a Redis top-level redis and CachePlugin on global-store is refused for background tasks first (tasks.store: false), and only after that switch is set for the plugin. For one error to name both, each plugin would have to declare its stores to the scope before its providers are built: a new plugin hook. The SDK's own check isn't a single call either, since questions and jobs are refused where they are set up. So the order is left as it is.
The other plugins under plugins/ (codecall, dashboard, feature-flags, skilled-openapi, webmcp) open no Redis or SQLite store. RememberStorageProvider is a standalone class that RememberPlugin does not use, so it is left as is.
User-facing change
What changed:
New export from @frontmcp/sdk: refusePluginStoreInBrowser({ plugin, option, memory }, runtime?) and its PluginStoreInBrowser type.
BrowserStoreUnavailableError now also covers plugin stores: new BrowserStoreUnavailableError(stores, pluginMemory?), with BrowserRefusedStore widened to take a plugin's name.
In a browser build, CachePlugin, RememberPlugin, ApprovalPlugin and ResultHandlesPlugin refuse a store on Redis or SQLite with that error. The message names the plugin and its memory option, e.g. CachePlugin would use type: 'redis' (set type: 'memory' in place of type: 'redis') and ApprovalPlugin would use storage: { type: 'sqlite' } (set storage: { type: 'memory' } in place of storage: { type: 'sqlite' }).
Before → after:
Browser, CachePlugin / RememberPlugin on global-store with a Redis top-level redis: the server started, opened an ioredis client, and the store failed on first use → startup fails with BrowserStoreUnavailableError before any connection, naming type: 'memory'.
Browser, type: 'redis' / 'redis-client': the client was built at init() → init() throws the same error.
Browser, ApprovalPlugin / ResultHandlesPlugin with storage on Redis or SQLite: memory with a warning, or a connection or module error in production → init() throws the same error, naming storage: { type: 'memory' }.
frontmcp-development/references/official-plugins.md: the browser refusal for the Remember and Cache storage types, and for Approval storage.
frontmcp-development/references/result-handles-plugin.md: the browser refusal for storage.
frontmcp-development/references/create-plugin.md: new section "A store a browser cannot open", which shows refusePluginStoreInBrowser() for plugin authors, its message and error.stores, and when to call it for a top-level redis.
frontmcp-deployment/references/build-for-browser.md: the official plugins refuse with the same error, what they did up to 1.10, and a link to the helper.
Also the global-store / storage sections of the READMEs of plugin-cache, plugin-remember, plugin-approval and plugin-result-handles.

Tests
Unit:
libs/sdk/src/scope/__tests__/browser-stores.spec.ts: refusePluginStoreInBrowser throws BrowserStoreUnavailableError in a browser with the plugin's stores entry and message, and names the plugin's option for a plugin named like an SDK store (jobs). It refuses nothing with option: undefined, on Node, or with the real runtime.
plugins/plugin-cache/src/__tests__/cache.plugin.browser-store.spec.ts and plugins/plugin-remember/src/__tests__/remember.browser-store.spec.ts set the runtime to browser (mocked getRuntimeContext) and check that:
a global-store server with a Redis top-level redis fails createDirect() with the error, and ioredis is never constructed;
init({ type: 'redis' | 'redis-client' }) throws before it connects;
type: 'memory' with the top-level redis left in the config, and a global-store on Vercel KV, both start.
On Node, global-store still builds its Redis client.
plugins/plugin-approval/src/__tests__/approval.browser-store.spec.ts and plugins/plugin-result-handles/src/__tests__/result-handles.browser-store.spec.ts: in a browser, storage: { type: 'redis' } and { type: 'sqlite' } throw from init() with the memory option named. Memory, auto, Vercel KV and (for Approval) a storageInstance given in place of storage are kept. On Node, Redis and SQLite are kept.
e2e:
apps/e2e/demo-e2e-bundle-size/e2e/browser-plugin-stores.e2e.spec.ts, modelled on browser-stores. It bundles a page (browser conditions, ES modules run by Node) with CachePlugin or RememberPlugin and a top-level redis that points at a TCP listener posing as Redis.
On global-store, startup fails with BROWSER_STORE_UNAVAILABLE and the plugin's message.
With type: 'memory' for both, the page starts and calls its tool without a warning.
The listener gets no connection either way.
Red first: before the fix, the cache and remember pages connected to the listener and never settled.
bundleEntriesWithSharedChunks takes { nodeRequire: true }, which gives each chunk a require(). The bundled ioredis (CommonJS) needs it to load Node's built-ins.
The project's build / test targets now depend on plugin-cache and plugin-remember builds.
sdk-root-exports.json pins the new refusePluginStoreInBrowser export.
apps/e2e/demo-e2e-dts-consumer: memory-stores-must-compile.ts types refusePluginStoreInBrowser, PluginStoreInBrowser and new BrowserStoreUnavailableError(stores, pluginMemory), and rejects a call without memory.

Summary by CodeRabbit
New Features
Browser builds now report BrowserStoreUnavailableError when Cache, Remember, Approval, or Result Handles plugins select unsupported Redis or SQLite stores, with guidance to use memory storage.
Vercel KV and memory storage remain available in browsers; server-side storage behavior is unchanged.
Bug Fixes
Cache plugin header bypass settings now require a nonempty x-frontmcp- header name.
Documentation
Added guidance on browser storage limitations and plugin store configuration.
…r build
CachePlugin and RememberPlugin on global-store took the top-level redis
in a page, which has no TCP socket: the store fell back to memory with a
warning or failed on its first call. refusePluginStoreInBrowser(), from
@frontmcp/sdk, throws BrowserStoreUnavailableError in a browser for a
plugin store that would open Redis or SQLite, naming the plugin option
that keeps it in memory. CachePlugin, RememberPlugin, ApprovalPlugin and
ResultHandlesPlugin call it where they build their store. Node servers
are unchanged.

Review comments at @libs/sdk/src/errors/browser-store.errors.ts:
- Line 18: Update BrowserStoreUnavailableError’s fallback for missing
pluginMemory entries so store names without a memory mapping produce a useful
message instead of “set undefined for memory”; preserve the existing
mapped-memory message when an entry is available.
Walkthrough
The SDK adds a shared helper for refusing plugin storage options in browser runtimes. Cache, Remember, Approval, and ResultHandles use the helper for selected Redis or SQLite configurations. Tests and documentation cover the refusal behavior and supported alternatives.

The SDK error supports plugin-specific store names and memory alternatives. The SDK exports a runtime-aware refusal helper. Tests, type-consumer coverage, and plugin-author guidance cover its behavior and input shape.
CachePlugin and RememberPlugin check Redis-backed configurations before creating or registering Redis providers. Tests cover browser refusals, allowed configurations, and Node behavior. Documentation describes the storage behavior and alternatives.
ApprovalPlugin and ResultHandlesPlugin check Redis or SQLite configurations in browser runtimes. Tests cover browser and Node behavior, while documentation describes the browser storage choices.
The browser E2E fixture exercises CachePlugin and RememberPlugin refusal and memory-store startup. The bundle helper can add a createRequire banner, and build targets include both plugin builds.

The supplied change evidence shows checks in the global-store factories before Redis provider creation. The added browser tests verify the error, the memory recommendation, and no ioredis construction. The Node tests verify that the Redis global-store path still builds.
