## Summary
- Adds the generated `@stackframe/tanstack-start` workspace package
registration.
- Adds TanStack Start platform macros/dependencies to the SDK template
and generator.
- Adds TanStack Start cookie/token-store support plus the handler SSR
guard needed by Start.
## Scope
This intentionally excludes Dashboard V2 routes, hooks, components, app
shell logic, and dashboard API type additions. Those stay in the
existing dashboard PR/branch.
## Validation
- `pnpm install --lockfile-only --ignore-scripts`
- `pnpm install --ignore-scripts`
- `pnpm -C packages/template lint
src/components-page/stack-handler-client.tsx src/lib/cookie.ts
src/lib/stack-app/apps/implementations/client-app-impl.ts`
Package typecheck was attempted with `pnpm -C packages/template
typecheck`, but the clean worktree lacks generated package declaration
outputs for workspace dependencies such as `@stackframe/stack-shared`
and `@stackframe/stack-ui`. Per repo instructions, package
builds/codegen are not run by agents.

## 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

## Summary
- Move the `/api/internal/[transport]` MCP route from the docs app to
the backend, so the public `ask_stack_auth` MCP tool is served from the
same origin as the AI query API it proxies to.
- Replace the bespoke docs-tools HTTP client in
`apps/backend/src/lib/ai/tools/docs.ts` with an `@ai-sdk/mcp` client
that talks to Mintlify's generated MCP server. The backend AI agent now
consumes Mintlify's lower-level search/fetch tools directly instead of
going through the docs app.
- Swap `STACK_DOCS_INTERNAL_BASE_URL` for `STACK_MINTLIFY_MCP_URL`
(defaults to the Mintlify-hosted MCP URL).
- Move the `@vercel/mcp-adapter` dependency from `docs` to
`apps/backend`.
## Test plan
- [ ] `pnpm typecheck`
- [ ] `pnpm lint`
- [ ] e2e: new
`apps/e2e/tests/backend/endpoints/api/v1/internal/mcp.test.ts` covers
`tools/list` and validation on `tools/call`
- [ ] Manual: hit `POST /api/internal/mcp` on the backend and confirm
`ask_stack_auth` is listed and callable
- [ ] Manual: confirm backend AI agent docs tools resolve via the
Mintlify MCP URL

## Documentation
* Updated setup instructions across all documentation to clarify that
the publishable client key is only required when your project

This PR implements unified AI endpoint and custom dashboards.
**Unified AI Endpoint**
We now use a single endpoint throughout the codebase that makes the call
to openrouter. Specifically, email drafts, email templates, email
themes, wysiwyg, cmd centre ai search and docs ai, all use this unified
ai endpoint. All the tools are defined in the backend, all the prompts
exist in the backend.
How to review this PR for unified ai endpoint:
This PR will be easier to review if we look at the different folders
that were affected.
under packages - We added streaming functionality, and made renaming
changes
under docs - there are three files that have changed
package.json - we updated the package (we were previously using a very
old version of the package)
route.ts - we changed the call from a direct call to openrouter to the
unified ai endpoint
ai-chat.tsx - because of updating the package, we had to make changes to
adapt to the latest versions of the package
under backend
route.ts - the main unified ai endpoint. this endpoint uses various
support files
forward.ts - this is the forward to production functionality
models.ts - consists of the models, and the rules for selecting those
models
prompts.ts - consists of the base prompt + specific system prompts
depending upon the usage
schema.ts
every single file under ai/tools folder - which as the name suggests,
consists of the implementations of the different tools that can be
provided to the llm
route-handlers - added support for streaming to SmartRoute and response
under dashboard
ai-search/route.ts - refactored the file to use unified ai endpoint
chat-adapters.ts - refactored the file to use unified ai endpoint and
created extra checks for the ai generated code
**Custom Dashboards**
We let the user write their query in english. We then use AI to create
dashboards that are interactive, live and savable. This PR includes a
new package called dashboard-ui-components. This package has components
that are used in the dashboard and more importantly, these components
are being imported from esm in the ai generated code for custom
dashboards. We also change the bar at the top for the products pages.
How to review this PR:
Review the new package (package/dashboard-ui-components), the setup and
the files inside it.
Review the schema changes in stack-shared/src
Review the changes in dashboard. The following changes have been made
Updated the design-components folder since we moved the dashboard
components to the new package
Updated imports for these components accordingly
Updated the title bar of the product pages
Created the files for custom dashboards under the dashboards folder and
components under commands/create-dashboard
Created a script under dashboard/scripts that generates the file with
type definitions that would go to the llm
Review the backend
Started using unified ai endpoint
