## Summary
**Stacked on [#1475](https://github.com/hexclave/stack-auth/pull/1475)**
(`cl/hexclave-pr1`, the invisible compatibility layer). Diff vs that
base = the actual PR 2 code.
This is **PR 2 of the Stack Auth → Hexclave rebrand: the visible flip**.
Old wire identifiers (cookies, request/response headers, Bearer prefix,
JWT issuers, MCP tool name) keep working indefinitely via PR 1's
dual-accept. This PR flips every user-visible surface — package names
taught in docs, SDK class names in code examples, dashboard setup
snippets, page titles, error messages, email content, CLI binary,
default base URLs, GitHub repo slug, contributor guidance — to the
Hexclave brand.
See [`RENAME-TO-HEXCLAVE.md`](./RENAME-TO-HEXCLAVE.md) → *"PR 2: Rebrand
to Hexclave (visible)"* for the full per-work-area spec.
## What's implemented (per the plan's PR 2 scope)
- **SDK base URLs** flipped: `defaultBaseUrl` and
`defaultAnalyticsBaseUrl` in
[common.ts](packages/template/src/lib/stack-app/apps/implementations/common.ts:127)
→ `https://api.hexclave.com` / `https://r.hexclave.com`. PR 1's
[`getHardcodedFallbackUrls`](packages/stack-shared/src/utils/urls.tsx:199)
table now keys on the Hexclave domain.
- **Domain inventory sweep** (16 subdomains from the plan): every
`api/app/docs/discord/demo/mcp/skill/feedback/test/preview/r/api2/api.staging/idp-jwk-audience/built-with.stack-auth.com`
reference in production code, docs-mintlify, examples, READMEs, and
contributor guidance flipped to `*.hexclave.com`. Carve-outs: PR 1's
intentional JWT issuer dual-accept table in
[tokens.tsx](apps/backend/src/lib/tokens.tsx), the legacy `./docs/`
folder, the `unified-docs-widget` allowlist (deliberately accepts both
during DNS transition), and `url-targets.ts` hosted-component default
(baked into existing customer deploys).
- **`@deprecated` JSDoc** on every `Stack*` public export
([packages/template/src/lib/stack-app/index.ts](packages/template/src/lib/stack-app/index.ts)
+ [packages/template/src/index.ts](packages/template/src/index.ts)) —
`StackClientApp`, `StackServerApp`, `StackAdminApp` + every
constructor/options/JSON type, `StackHandler`, `StackProvider`,
`StackTheme`, `useStackApp`, `defineStackConfig`, `StackConfig`.
Hexclave\* aliases are now canonical.
- **Runtime `console.warn`**
([packages/template/src/internal/deprecation-warning.ts](packages/template/src/internal/deprecation-warning.ts))
— once-per-process when the SDK is loaded from a `@stackframe/*`
artifact. Detection uses the existing
`STACK_COMPILE_TIME_CLIENT_PACKAGE_VERSION_SENTINEL` (rewritten at build
time to e.g. `js @stackframe/stack@2.8.92` or `js
@hexclave/next@1.0.0`); `@hexclave/*` mirror artifacts short-circuit the
warning.
- **Tier 3 data migration**: new idempotent SQL migration
[`20260523000000_rename_internal_project_to_hexclave`](apps/backend/prisma/migrations/20260523000000_rename_internal_project_to_hexclave/migration.sql)
— updates the internal Project `displayName` 'Stack Dashboard' →
'Hexclave Dashboard' and `description` only if both still hold the
pre-rebrand defaults. Operator-renamed projects untouched, missing row
no-ops, re-runs are no-ops. [`seed.ts`](apps/backend/prisma/seed.ts:87)
default flipped. `getSharedEmailConfig("Stack Auth")` → `("Hexclave")`.
- **Tier 4 brand strings** (mechanical sweep, ~340 files):
- Page + OpenAPI titles (Hexclave API / Dashboard / REST API / Webhooks
API / Documentation). OpenAPI `info.description` documents
`X-Hexclave-*` headers as canonical with compat note on `X-Stack-*`.
- `HexclaveAssertionError` message text
([errors.tsx:71](packages/stack-shared/src/utils/errors.tsx:71)) — "an
error in Stack." → "an error in Hexclave."
- Known-error message templates
([known-errors.tsx](packages/stack-shared/src/known-errors.tsx)) flipped
to lead with `x-hexclave-*` + the new `docs.hexclave.com` URL; legacy
`x-stack-*` mentioned as compat aliases. **25 e2e test files updated in
lockstep**.
- Email content: failed-emails-digest body, sendTestEmail recipient (now
`sent-with-hexclave.com`), test-email-recipient default.
- `CHANGELOG.md` title → "Hexclave Changelog".
- `AGENTS.md` env var convention: new vars prefix `HEXCLAVE_` /
`NEXT_PUBLIC_HEXCLAVE_` for Category A/B; legacy `STACK_*` explicitly
noted as accepted via PR 1's dual-read.
- **CLI / init wizard**:
- Every dashboard setup snippet, init-stack template, and docs-mintlify
page teaches `npx @hexclave/cli@latest init` (was
`@stackframe/stack-cli`).
[setup-page.tsx](apps/dashboard/src/app/(main)/(protected)/projects/[projectId]/(overview)/setup-page.tsx)
+
[link-existing-onboarding](apps/dashboard/src/app/(main)/(protected)/(outside-dashboard)/new-project/page-client-parts/link-existing-onboarding.tsx).
- [init-stack](packages/init-stack/src/index.ts:634)
`STACK_*_INSTALL_PACKAGE_NAME_OVERRIDE` defaults flipped to
`@hexclave/*`.
- Generated `stack/client.ts` / `stack/server.ts` import from
`@hexclave/next` and reference `HexclaveClientApp` /
`HexclaveServerApp`.
- Internal `StackAuthKeys` dashboard component renamed to
`HexclaveKeys`.
- **docs-mintlify rewrite** (legacy `./docs/` intentionally untouched
per scoping decision):
- **78 MDX files swept**.
`@stackframe/{react,stack,js,tanstack-start,...}` →
`@hexclave/{react,stack,js,...}` in install snippets and code blocks;
`Stack*` SDK class names → `Hexclave*` in all code examples; 'Stack
Auth' brand phrase → 'Hexclave'.
- `openapi/{server,admin,client,webhooks}.json` titles → 'Hexclave REST
API' / 'Hexclave Webhooks API'.
- **Generators flipped before regeneration**:
-
[`packages/stack-shared/src/helpers/init-prompt.ts`](packages/stack-shared/src/helpers/init-prompt.ts),
[`/ai/prompts.ts`](packages/stack-shared/src/ai/prompts.ts),
[`apps/backend/src/lib/ai/prompts.ts`](apps/backend/src/lib/ai/prompts.ts),
[`apps/backend/src/lib/ai/tools/create-email-{template,draft}.ts`](apps/backend/src/lib/ai/tools/create-email-template.ts),
[`apps/skills/src/app/route.ts`](apps/skills/src/app/route.ts) (taught
MCP tool → `ask_hexclave` with compat note; CLI binary teach →
`hexclave`),
[`docs-mintlify/snippets/home-prompt-island.jsx`](docs-mintlify/snippets/home-prompt-island.jsx),
[`packages/template/README.md`](packages/template/README.md) +
integrations/convex/component/README.md.
- `generate-sdks` propagated changes to `packages/{react,stack,js}`.
- **OpenAPI dual-documentation**:
[`apps/backend/src/app/api/latest/route.ts`](apps/backend/src/app/api/latest/route.ts)
now lists `X-Hexclave-*` headers as primary documented schemas with
`X-Stack-*` duplicates marked `.optional()` (both accepted at runtime by
PR 1's normalize-at-proxy shim).
- **`@stackframe/emails` virtual module**: dual-aliased to
`@hexclave/emails` at the bundler boundary
([email-rendering.tsx:89](apps/backend/src/lib/email-rendering.tsx:89)).
Stored email templates continue to import from either name; new
AI-generated templates and the system prompt teach `@hexclave/emails`.
- **Tier 2 mirror-publish wiring** (new this PR, lays the groundwork for
`@hexclave/*` first publish):
-
[`scripts/rewrite-packages-to-hexclave.ts`](scripts/rewrite-packages-to-hexclave.ts)
— rewrites 9 publishable `@stackframe/*` → `@hexclave/*` `package.json`
files (reads `HEXCLAVE_VERSION` env or `--version=` flag), pins
cross-deps to the shared `@hexclave` version, registers `hexclave` bin
alongside `stack` for `@hexclave/cli`.
-
[`.github/workflows/npm-publish.yaml`](.github/workflows/npm-publish.yaml)
appended with rewrite-then-republish step. `pnpm publish` skips
already-on-npm versions so reruns are safe.
- **Sender email domain**: `noreply@stackframe.co` →
`noreply@sent-with-hexclave.com` (the dedicated transactional-sender
domain split per the plan, to isolate bulk deliverability from
`hexclave.com` reputation); `security@` / `team@stack-auth.com` inbound
mailboxes → `@hexclave.com`.
- **Self-host docs**: docker network / container names in the bash
examples flipped from `stack-auth` to `hexclave` (`hexclave-postgres`,
`hexclave-clickhouse`, `hexclave.env`). The docker image tag
`stackauth/server:latest` stays per the plan's locked decision.
- **GitHub repo slug**: `hexclave/stack-auth` → `hexclave/hexclave` in
every `package.json` `repository` field, README link, CHANGELOG
raw-asset URL.
## Carve-outs (deliberately untouched)
-
**[`apps/backend/src/lib/tokens.tsx`](apps/backend/src/lib/tokens.tsx)**
JWT issuer dual-accept table — PR 1 intentional infrastructure, kept
indefinitely.
- **Legacy `./docs/` folder** — per scoping decision (only
`docs-mintlify/` rewritten).
- **`unified-docs-widget` hostname allowlist** — accepts both
`.hexclave.com` (canonical) and `.stack-auth.com` (transition window)
for DNS rollout.
- **`url-targets.ts`** hosted-domain default
`.built-with-stack-auth.com` — wire identifier baked into existing
customer deploys; indefinite read-fallback.
- **Binary visual assets** (logos, favicons, OG images, README
screenshots) — out of scope for this PR. Need design work; tracked
separately.
## Verification
- **`pnpm typecheck`** on
`packages/{template,stack-shared,react,stack,js}` + `apps/dashboard`:
**all green**. The remaining backend / e-commerce-demo typecheck errors
are pre-existing (Prisma codegen output +
`./generated/api-versions.json` not present in fresh worktrees without
`pnpm run codegen-prisma` + a live DB) and unrelated to this diff.
- **`pnpm lint`** on the same 6 packages: all green.
- **Final grep** for residual `Stack Auth` / `stack-auth.com` /
`@stackframe/stack-cli@latest` references: zero outside the intentional
carve-outs above.
- **25 e2e test files updated in lockstep** with the known-error message
changes (asserted strings flipped to match the new x-hexclave-* +
compat-note messages).
## Deploy blockers (ops sequencing before this rebrand goes live)
This PR is code-complete, but the rebrand's visible surfaces (SDK
default URLs, dashboard links, npm READMEs, REST error messages, runtime
deprecation warning) all point at `*.hexclave.com` / `@hexclave/*`
resources that don't exist yet. None of these are fixable from a PR —
they're ops/registrar/npm work that has to be sequenced before merging
this to a release tag.
Suggested ordering, hardest blockers first:
### Tier 1 — required before customer-facing deploy (everything below
this line *will visibly break customers on day 1* if skipped)
1. **DNS + TLS for `api.hexclave.com` + `api1./api2.hexclave.com`** →
must point at the same backend that serves `api.stack-auth.com` (or a
backend that mirrors PR 1's dual-accept). The SDK's new `defaultBaseUrl`
is `https://api.hexclave.com`; every customer that relied on the old
default and upgrades to a post-PR2 SDK build sends API requests here.
Until this resolves, every default-config customer's API call NXDOMAINs.
2. **DNS for `app.hexclave.com`** → the dashboard. Referenced in the
SDK's default-error messages ("Please create a project on the Hexclave
dashboard at https://app.hexclave.com"), the init-stack flow's
`wizard-congrats` redirect, and the OAuth dashboard handoff.
3. **DNS for `docs.hexclave.com`** + Mintlify deploy → the SDK runtime
deprecation warning (`https://docs.hexclave.com/migration`), every
README, every "Learn more" link in the dashboard, and every REST API
error body (`/api/overview#authentication`) points here. The MDX is in
this PR; the docs build target needs DNS.
4. **DNS for `mcp.hexclave.com`** → the MCP server endpoint that every
taught agent integration (`claude mcp add ...`, `cursor`, `codex`,
`vscode`) registers. Until this resolves, every `npx
@hexclave/cli@latest init` MCP-registration step fails.
5. **Reserve the `@hexclave` npm scope + set repo variable
`HEXCLAVE_VERSION`** → the mirror-publish step in
`.github/workflows/npm-publish.yaml` is gated on this variable. Without
it, the entire taught onboarding command `npx @hexclave/cli@latest init`
404s from the npm registry, *and* every README that says "install
`@hexclave/next`" leads to install failure. Pick the initial version
intentionally (`1.0.0` or aligned to `@stackframe/stack`); don't accept
a silent default.
### Tier 2 — required before announcing the rebrand publicly (lookalike
or low-traffic surfaces, but visibly broken)
6. **DNS for `r.hexclave.com`** → the analytics beacon
`defaultAnalyticsBaseUrl`. Silent failure if missing (analytics drops),
but should land alongside Tier 1.
7. **Register `sent-with-hexclave.com` + full email auth (SPF / DKIM /
DMARC)** → the new default sender domain for shared-sender transactional
emails. Without it the dashboard "send test email" path emits bounces,
and shared-sender flows (`getSharedEmailConfig("Hexclave")`) deliver to
spam at best.
8. **MX + SPF / DMARC for `hexclave.com`** → `team@hexclave.com` and
`security@hexclave.com` mailboxes. The security disclosure mailbox is
referenced in [`.github/SECURITY.md`](.github/SECURITY.md);
`team@hexclave.com` is the actual recipient of internal feedback emails
sent at runtime by
[`apps/backend/src/lib/internal-feedback-emails.tsx`](apps/backend/src/lib/internal-feedback-emails.tsx).
Today, every runtime feedback email bounces.
9. **DNS for `skill.hexclave.com`** → the canonical AI-agent skill fetch
URL (the agent bootstrap pivot). Without it, the entire "agent downloads
`SKILL.md` from a known URL" flow taught in
[`packages/stack-shared/src/helpers/init-prompt.ts`](packages/stack-shared/src/helpers/init-prompt.ts)
fails.
10. **Create `github.com/hexclave/hexclave` as a public repo** (even as
a redirect to `hexclave/stack-auth`) **OR** rewrite every `package.json`
`"repository"` field + dashboard footer "view on GitHub" link to point
at `hexclave/stack-auth` (which already exists). Currently every npm
package page's "Repository" link is dead, and the dashboard's GitHub
button + dev-tool repo link are dead.
### Tier 3 — broken but low-visibility / low-traffic
11. **DNS for `discord.hexclave.com`** → Discord invite redirect, used
in every README's chip and the dashboard footer.
12. **DNS for `demo.hexclave.com`** → "✨ Demo" badge in every npm
package README. Broken-image badge on the package page.
13. **DNS + TLS for `built-with-hexclave.com`** → optional
hosted-handler domain (the default reverted to
`.built-with-stack-auth.com` in this PR's carve-outs, so this only
matters for projects that manually flip).
## Other follow-ups (not deploy-blocking)
- **E2E snapshot regen across the full suite** for the dual-emitted
`x-hexclave-*` response headers (PR 1 follow-up; `vitest -u` in CI
absorbs).
- **Binary visual assets** — logos, favicons, OG images, README
screenshots; need design pass.
- **Backend OpenAPI fumadocs regen** in CI flow — the JSON files in
`docs-mintlify/openapi/` are committed but regen runs in CI. Verify the
workflow that does this still works against the post-PR2 source.
- **Backend typecheck infra debt** — needs `codegen-prisma` +
`codegen-route-info` to clear; pre-existing, unaffected by this PR.
## Test plan
- [ ] CI runs full e2e suite (with `vitest -u` to absorb residual
snapshot deltas, then committed back).
- [ ] Spot-check: new `@hexclave/cli init` (once published) generates
`hexclave.config.ts` and works against a fresh project.
- [ ] Spot-check: existing customer with `@stackframe/stack` import sees
the once-per-process `console.warn` recommending `@hexclave/next` on SDK
init.
- [ ] Manual: dashboard setup page renders the `npx @hexclave/cli@latest
init` snippet and the `x-hexclave-publishable-client-key` API header in
the curl example.
- [ ] Manual: a fresh `pnpm run prisma migrate` against a clean DB sets
the internal project displayName to 'Hexclave Dashboard'.

## Summary
**Stacked on #1468** (`docs/hexclave-rename-plan` — the plan doc). Diff
vs that base = the actual PR 1 code.
This is **PR 1 of the Hexclave rebrand: the invisible compatibility
layer**. Everything is additive. Old SDKs, old wire identifiers, and old
env var names keep working unchanged. The backend dual-accepts and
dual-emits; new SDK code emits `x-hexclave-*` headers and the
`hexclave_` Bearer prefix; cookies dual-write; env vars dual-read across
every category. **No user-visible rebranding lands here** — that's PR 2.
See [`RENAME-TO-HEXCLAVE.md`](./RENAME-TO-HEXCLAVE.md) → *"PR 1
implementation guide"* for the full per-work-area spec, file pointers,
and chosen approach.
## What's implemented (all 14 PR-1 work-areas)
- **SDK export aliases** — `Hexclave*` aliases for the user-facing
`Stack*` exports added in `packages/template`; codegen propagates them
to `@stackframe/{js,stack,react,tanstack-start}`. React-only aliases
correctly excluded from `@stackframe/js`. (`e60550a2`)
- **JWT issuer dual-accept** — `decodeAccessToken` accepts both
`api.stack-auth.com` and `api.hexclave.com` issuers. Signing unchanged.
(`fc781def`)
- **Request-header dual-accept** — backend + dashboard proxies normalize
`x-hexclave-*` → `x-stack-*` at the existing empty proxy hook (so
`smart-request.tsx` and every route schema keep working unchanged); CORS
allowlists extended via a derive-once helper. (`2a056eac`)
- **MCP `ask_hexclave`** — registered alongside `ask_stack_auth` via a
shared helper; `ask_stack_auth` behavior byte-identical. (`30ffd604`)
- **Dev-tool** — DOM ids + header emit switched.
`window.HexclaveDevTool` exposed alongside `window.StackDevTool`.
(`32131ea7`)
- **The big consolidated commit** (`7fed864a`):
- **Env vars** — central `getEnvVariable` prefix-transform (HEXCLAVE
first, STACK fallback); dashboard + template client env files dual-read;
`turbo.json` globalEnv; `NEXT_PUBLIC_STACK_PORT_PREFIX` renamed outright
across ~82 files including docker.
- **Cookies** — dual-write/dual-read auth (`stack-access`/`-refresh-*`
and custom-domain variants), OAuth-state
(`stack-oauth-{inner,outer}-*`), and low-risk cookies (`stack-is-https`,
`stack-last-seen-changelog-version`). Bypass sites patched (backend
OAuth callback, dashboard remote-dev auth route, impersonation snippets,
snapshot serializer).
- **Bearer prefix** — SDK token parser accepts both `stackauth_` and
`hexclave_`; emits `hexclave_`. Discovery correction: this is purely
SDK-internal — the backend never parses it.
- **Response headers** — backend dual-emits
`x-hexclave-{request-id,actual-status,known-error}`; SDKs dual-read (new
first, stack fallback).
- **SDK request-header emit switch** —
`client/server/admin-interface.ts` + dashboard `api-headers.ts` +
`internal-project-headers.ts` + `feedback-form.tsx` switched to
`x-hexclave-*`. Plus `stack_response_mode` query param.
- **Storage keys** — dev-tool / cli-auth / oauth-button / docs keys
renamed (straight); `stack:session-replay:v1` dual-read so in-progress
recordings survive SDK upgrades; `stack_mfa_attempt_code` dual-read.
- **Query params** — cross-domain params dual-emit/dual-accept via
shared helpers; backend `oauth/authorize` accepts
`hexclave_response_mode` and `stack_response_mode`; `stack-init-id`
renamed.
- **`Symbol.for`** — app-internals symbol gets a parallel
`Symbol.for("Hexclave--app-internals")` getter on each attach site (no
read-site churn — old symbol still attached). 3 file-private symbols
renamed outright.
- **Config discovery** — prefer `hexclave.config.ts`, fall back to
`stack.config.ts` at every discovery site (CLI / dashboard / backend /
local-emulator); `init` writes the new filename; CLI credentials path
migrates.
- **Internal renames** — `StackAssertionError`,
`StackClient/Server/AdminInterface` renamed outright (no alias, per the
"internal-only → rename" rule). ~264 files touched.
- **Review-pass fixes** (`21217fbe`) — three real bugs found by parallel
review agents and fixed:
- `snapshot-serializer.ts` was interpolating the whole
`keyedCookieNamePrefixes` array (`${arr}`) — adding a second prefix
would have corrupted **every** OAuth-cookie snapshot, not just new ones.
- **Docker port-prefix producer/consumer mismatch** —
`entrypoint.sh`/`run-emulator.sh`/cloud-init `user-data` were still
producing `NEXT_PUBLIC_STACK_PORT_PREFIX` while the dashboard sentinel +
consumers had been renamed; silent self-host regression (custom port
prefix would be ignored).
- **Missing `hexclave-oauth-inner-*` dual-write** in the OAuth authorize
route — callback's fallback masked it but the dual-write was specified
by the plan.
- Plus: `mcp.test.ts` tool-list assertions updated to include
`ask_hexclave`; two dashboard header-emit sites switched to
`x-hexclave-*` for consistency.
- **E2E snapshot serializer follow-up** (`4b16cc5d`) —
`x-hexclave-request-id` added to the hidden-headers list (mirroring
`x-stack-request-id` treatment), and 2 sample inline snapshots
regenerated in `projects.test.ts` to include the new dual-emitted
headers.
## Verification
- **`pnpm typecheck`** — clean (the fresh-worktree `@/.source` / Prisma
codegen gap in `stack-docs` is pre-existing and unrelated).
- **`pnpm lint`** — 29/29 packages green.
- **`pnpm exec turbo run build --filter=./packages/*`** — 13/13 packages
build (including `@stackframe/stack-cli` once the dashboard standalone
is present).
- **Live E2E** against a running backend on `cl/hexclave-pr1`:
- `pnpm test run
apps/e2e/tests/backend/endpoints/api/v1/internal/mcp.test.ts` — **6/6
pass** (verifies the new `ask_hexclave` tool — the hand-written inline
snapshot matched actual MCP server output).
- `pnpm test run
apps/e2e/tests/backend/endpoints/api/v1/internal/projects.test.ts` —
**11/11 pass** (verifies wire dual-accept + dual-emit end-to-end; the
snapshot serializer fix was found and applied during this check).
A four-agent parallel **review pass** also audited the full diff for
logic/runtime bugs across the work-areas (wire headers + JWT, cookies +
bearer + symbols, env vars, query params + config + MCP + aliases). All
in-slice review verdicts were ✓ except the three bugs listed above,
which are now fixed.
## Known follow-ups (out of scope for this PR)
- **E2E snapshots across the rest of the suite** — backend now
dual-emits `x-hexclave-{known-error,actual-status}` alongside
`x-stack-*`, which legitimately appears in inline snapshots throughout
`apps/e2e`. Two were regenerated here as a sample; the rest should regen
with `vitest -u` in CI.
- **Docker shell env vars beyond `PORT_PREFIX`** — `entrypoint.sh` still
reads `STACK_*` env vars directly (the JS-side `getEnvVariable`
transform doesn't help the shell). JS consumers dual-read so it works in
practice; full shell-level dual-read is a deeper self-host follow-up.
- **`@stackframe/stack-cli` build ordering** — pre-existing; needs
`build:rde-standalone` first. Not affected by this PR.
## Test plan
- [ ] CI runs full e2e suite (with `vitest -u` to absorb dual-emit
snapshot deltas, then committed back)
- [ ] Spot-check: an old SDK build (emitting only `x-stack-*`) still
authenticates against the new backend
- [ ] Spot-check: a new SDK (emitting `x-hexclave-*` / `Bearer
hexclave_*`) still authenticates against an old backend during deploy
ordering
- [ ] Manual: `npx @stackframe/stack-cli@latest init` (new onboarding
entrypoint) generates `hexclave.config.ts`
- [ ] Manual: existing `stack.config.ts`-only project still resolves (no
migration required)

## Summary
Splits the Stack Auth MCP server out of `apps/backend` and into a
dedicated Next.js app at `apps/mcp/`, served on port `:42` (suffixed via
`NEXT_PUBLIC_STACK_PORT_PREFIX`) and exposed in production at
`https://mcp.stack-auth.com/mcp`. The backend no longer carries the MCP
transport route; clients now point at the new host.
Base: `dev` → Head: `chore/move-mcp-to-a-sep-app`
Scope: 34 files, +1425 / −353
## What changed
- **New app** `apps/mcp/` — standalone Next.js + `@vercel/mcp-adapter`,
with:
- `src/app/api/internal/[transport]/route.ts` — MCP transport handler
(moved from backend)
- `src/app/mcp/route.ts`, `src/app/route.ts` — public landing + setup
page
- `src/app/health/route.ts` — health check
- `src/mcp-handler.ts`, `src/setup-page.ts`, `src/analytics.ts`
- **Backend** drops
`apps/backend/src/app/api/internal/[transport]/route.ts` (−105) — MCP
code is gone from the backend image.
- **Dashboard** install hint updated to point at
`https://mcp.stack-auth.com/mcp` (was `/`).
- **Dev launchpad** gets an MCP tile so the new service shows up
alongside the rest of the local stack.
- **CI** workflows (`db-migration-backwards-compatibility`,
`e2e-api-tests*`) start the MCP service in the background before running
tests.
- **Docs** (`docs-mintlify`, `docs/`) and `init-stack` / `init-prompt`
updated to reference the new URL.
- **E2E** `apps/e2e/tests/backend/endpoints/api/v1/internal/mcp.test.ts`
reworked to hit the new host; `helpers.ts` and env files gain an MCP
base-URL var.
## Visuals
### New `apps/mcp` setup page (`https://mcp.stack-auth.com/`)
The standalone app's root now serves a self-contained MCP setup guide
with per-client instructions (Cursor, VS Code, Codex, Claude Code,
Claude Desktop, Windsurf, ChatGPT, Gemini CLI):

### Dev launchpad now lists the MCP service
New tile at port suffix `:42`, importance 2, alongside Backend /
Dashboard / Demo app:

## Notes for reviewers
- The MCP transport endpoint moved path: it was mounted under
`/api/internal/[transport]` in the backend; in the new app it's at the
same path but on the dedicated host. The public-facing URL is
`https://mcp.stack-auth.com/mcp`.
- `apps/mcp` ships its own PostHog analytics client (`src/analytics.ts`)
so the backend doesn't have to proxy events for it anymore.
- Port allocation: `${PORT_PREFIX}42` (default `8142` in dev). Picked to
fit the existing dev-launchpad importance-2 row.
- No DB migrations.
## Test plan
- [x] `apps/mcp` builds and `pnpm dev` serves on `:8142`
- [x] Dev launchpad renders the new MCP tile (screenshot above)
- [x] MCP setup page renders client tabs (screenshot above)
- [x] E2E `mcp.test.ts` updated to hit the new host
- [ ] CI green on `e2e-api-tests*` and
`db-migration-backwards-compatibility` workflows (they were touched to
start the MCP service)
- [ ] `init-stack` / `mcp.ts` install flow lands users on the new URL
