## Summary
Claude.ai's custom remote MCP connector fails with "Couldn't reach the
MCP server" after successfully completing OAuth dynamic client
registration. Driving the flow through Chrome DevTools showed Claude's
backend creates our DCR client (many hundreds of orphan rows visible in
the admin panel), then never returns the user to `/authorize` — it gives
up silently.
**Empirical comparison against known-working MCP servers Claude.ai
connects to identified one concrete difference**: every server that
works returns `registration_client_uri` in the DCR response. We didn't.
| Server | DCR `registration_client_uri` | Claude.ai web connector |
|---|---|---|
| Linear (`mcp.linear.app`) | `/register/<client_id>` | ✅ works |
| Sentry (`mcp.sentry.dev`) | `/oauth/register/<client_id>` | ✅ works |
| Atlassian (`mcp.atlassian.com`) | yes | ✅ works |
| **Twenty** (before this PR) | **missing** | ❌ "Couldn't reach" |
## What this PR changes
### 1. Add `registration_client_uri` to the DCR response
```
{
"client_id": "…",
…existing fields…,
+ "registration_client_uri": "<issuer>/oauth/register/<client_id>"
}
```
Pointer at the registration's management endpoint per RFC 7591 §3.2.1.
Marked OPTIONAL in the spec but empirically required by Claude.ai.
### 2. New `GET /oauth/register/:clientId` endpoint (RFC 7592 read-back)
Returns public registration metadata (`client_name`, `redirect_uris`,
`grant_types`, `scope`, etc.). 404 for unknown clients.
No `registration_access_token` is issued (and none required to hit this
endpoint): the `client_id` is an unguessable UUID and the fields
returned are already public-readable via
`findApplicationRegistrationByClientId` GraphQL. This matches Linear's
behaviour — they return a `registration_client_uri` but issue no access
token.
### 3. Advertise `response_modes_supported: ["query"]` in AS metadata
RFC 8414 default, but explicitly listed by Linear / Sentry / Atlassian
and absent from ours. Some clients treat its absence as a capability
gap.
## Why I'm confident this is the root cause
- The failure mode exactly matches an orphaned-DCR retry loop (hundreds
of registrations, none `installed` on a workspace).
- #19847 reporter confirmed Claude Desktop + VS Code work — those
clients use the MCP Python SDK which doesn't require
`registration_client_uri`. **Claude.ai web** uses Anthropic's
proprietary backend client (`User-Agent: Claude-User`), which
empirically does.
- All 3 working reference servers return the field; we were the odd one
out.
## Test plan
- [x] `tsc --noEmit` clean on touched files
- [x] `yarn jest
--testPathPatterns="oauth-discovery.controller|mcp-auth.guard"` → 4/4
pass
- [ ] After deploy:
```bash
curl -s -X POST https://<host>/oauth/register -H 'Content-Type:
application/json' \
-d
'{"client_name":"probe","redirect_uris":["https://claude.ai/api/mcp/auth_callback"],"token_endpoint_auth_method":"none"}'
\
| jq .registration_client_uri
# expect: "https://<host>/oauth/register/<uuid>"
```
- [ ] After deploy: add the MCP connector in Claude.ai — user should now
reach the Twenty `/authorize` page
## Honesty
This is the nth fix in a long debugging chain. Unlike the earlier round
of fixes (which were real spec-compliance bugs but not Claude's
blocker), this one is backed by empirical evidence across 3
known-working implementations. If Claude.ai still fails after this
deploys, the remaining delta is `cli_client_id` in AS metadata
(non-standard field, could confuse strict parsers) or a field we
advertise that others don't (e.g. `client_credentials` grant) — both
small, removable, not disruptive.

## Summary
Three small spec-compliance fixes called out in an audit against the
[MCP authorization spec
(draft)](https://modelcontextprotocol.io/specification/draft/basic/authorization)
and RFC 9728 / RFC 9207.
### 1. Split Protected Resource Metadata by path (RFC 9728 §3.2)
> The `resource` value returned MUST be identical to the protected
resource's resource identifier value into which the well-known URI path
suffix was inserted.
Today a single handler serves both
\`/.well-known/oauth-protected-resource\` and
\`/.well-known/oauth-protected-resource/mcp\` and returns \`resource:
<origin>/mcp\` from both. That's wrong for the root form — per RFC 9728
the root URL corresponds to the **origin as resource**, and only the
\`/mcp\`-suffixed URL corresponds to \`<origin>/mcp\`.
After this PR:
| Request | `resource` field |
|---|---|
| `GET /.well-known/oauth-protected-resource` | `https://<host>` |
| `GET /.well-known/oauth-protected-resource/mcp` | `https://<host>/mcp`
|
Both still return the same `authorization_servers`, `scopes_supported`,
and `bearer_methods_supported`.
Claude's current flow happens to work because our WWW-Authenticate
points at the root form and Claude compares `resource` against what it
connected to. Strict clients probing the path-aware URL first were
rejecting us.
### 2. Advertise `authorization_response_iss_parameter_supported: true`
(RFC 9207)
Defense against OAuth mix-up attacks. Required by the [OAuth 2.1
security
BCP](https://datatracker.ietf.org/doc/html/draft-ietf-oauth-v2-1).
Signals that clients receiving an authorization response will find the
issuer in the `iss` parameter and can validate it.
### 3. Fix `WWW-Authenticate` challenge: point at path-aware PRM URL,
add `scope` param
- Was: `Bearer
resource_metadata=\"https://<host>/.well-known/oauth-protected-resource\"`
- Now: `Bearer
resource_metadata=\"https://<host>/.well-known/oauth-protected-resource/mcp\",
scope=\"api profile\"`
After change (1), only the path-aware URL returns a PRM document whose
`resource` matches what the MCP client connected to (\`<host>/mcp\`).
Pointing clients at the right URL keeps discovery consistent.
The `scope` parameter is a SHOULD in RFC 6750 and lets clients ask for
least-privilege scopes on first authorization.
## Not in this PR (queued separately)
From the same audit:
- **Audit JWT `aud` (audience) validation** — the spec requires the
server to reject tokens whose audience doesn't match this resource. Need
a read-only code review to confirm; filing as a follow-up.
- **Audit PKCE enforcement** — we advertise
`code_challenge_methods_supported: [\"S256\"]`; need to confirm the
\`/authorize\` flow actually rejects requests missing `code_challenge`.
- **403 `insufficient_scope` challenge format** for step-up auth.
- **CIMD (Client ID Metadata Documents)** support — newer spec
alternative to DCR.

## Summary
Adding `https://api.twenty.com/mcp` as an MCP server in Claude fails
with `Couldn't reach the MCP server` before OAuth can start. Two
independent bugs cause this:
1. **Missing path-aware well-known route.** The latest MCP spec
instructs clients to probe `/.well-known/oauth-protected-resource/mcp`
before `/.well-known/oauth-protected-resource`. Only the root path was
registered, so the path-aware request fell through to
`ServeStaticModule` and returned the SPA's `index.html` with HTTP 200.
Strict clients (Claude.ai) tried to parse it as JSON and gave up. Fixed
by registering both paths on the same handler.
2. **Stale protocol version.** Server advertised `2024-11-05`, which
predates Streamable HTTP. We've implemented Streamable HTTP (SSE
response format was added in #19528), so bumped to `2025-06-18`.
Reproduction before the fix:
```
$ curl -s -o /dev/null -w "%{http_code} %{content_type}\n" https://api.twenty.com/.well-known/oauth-protected-resource/mcp
200 text/html; charset=UTF-8
```
After the fix this returns `application/json` with the RFC 9728 metadata
document.
Note: this is separate from #19755 (host-aware resource URL for
multi-host deployments).
## Test plan
- [x] `npx jest oauth-discovery.controller` — 2/2 tests pass, including
one asserting both routes are registered
- [x] `npx nx lint:diff-with-main twenty-server` passes
- [ ] After deploy, `curl

## Summary
Follow-up to #19755. Simplifies `OAuthDiscoveryController` by dropping
the `authorization_endpoint → frontend base URL` branch that was there
to make `api.twenty.com/mcp` paste-able in MCP clients.
We've decided not to support pasting `api.twenty.com/mcp` — users can
paste `app.twenty.com/mcp`, `<workspace>.twenty.com/mcp`, or a custom
domain, all of which serve both frontend and API. On those hosts,
`authorization_endpoint` was already pointed at the same host as
`issuer`, which is what we want.
## Change
- Remove `isApiHost` helper and the `authorizeBase` branch — use
`issuer` for `authorization_endpoint`.
- Drop now-unused `TwentyConfigService` and `DomainServerConfigService`
injections.
- Drop duplicate `DomainServerConfigModule` import from
`application-oauth.module.ts` (the module is no longer needed).
Net diff: +1 / -22 across 2 files.
## Breaking change
MCP clients configured with `https://api.twenty.com/mcp` will stop
working. They should be reconfigured with the host matching the
workspace they're connecting to (`<workspace>.twenty.com/mcp`,
`app.twenty.com/mcp`, or a custom domain).
## Test plan
- [x] `yarn jest --testPathPatterns="mcp-auth.guard"` → 2/2 passing
(unchanged)
- [x] `tsc --noEmit` clean on modified files
- [ ] Manual verification on staging: `app.twenty.com/mcp` and
`<workspace>.twenty.com/mcp` OAuth flow still works end-to-end

## Summary
OAuth discovery metadata (RFC 9728 protected-resource, RFC 8414
authorization-server) and the MCP `WWW-Authenticate` header were
hardcoded to `SERVER_URL`. This breaks MCP clients that paste any URL
other than `api.twenty.com/mcp` — the metadata declares `resource:
https://api.twenty.com/mcp`, which doesn't match the URL the client
connected to, so the client rejects it and the OAuth flow never starts.
Reproduced with Claude's MCP integration: pasting
`<workspace>.twenty.com/mcp`, `app.twenty.com/mcp`, or a custom domain
returned *"Couldn't reach the MCP server"* because discovery returned a
resource URL for a different host.
Related memory: MCP clients POST to the URL the user entered, not the
discovered resource URL — so every paste-able hostname has to advertise
`resource` for that same hostname.
## What the server now does
`WorkspaceDomainsService.getValidatedRequestBaseUrl(req)` resolves the
canonical base URL for the host the request came in on, validated
against the set of hosts we actually serve:
- `SERVER_URL` (e.g. `api.twenty.com`) — API host
- default base URL (e.g. `app.twenty.com`) — the `DEFAULT_SUBDOMAIN`
base
- `FRONTEND_URL` bare host
- any `<workspace>.twenty.com` subdomain (DB lookup)
- any workspace `customDomain` where `isCustomDomainEnabled = true`
- any registered `publicDomain`
An unrecognized / spoofed Host falls back to
`DomainServerConfigService.getBaseUrl()`. **We never reflect arbitrary
Host values into the response.**
Callers updated:
- `OAuthDiscoveryController.getProtectedResourceMetadata` — echoes the
validated host into `resource` and `authorization_servers`.
- `OAuthDiscoveryController.getAuthorizationServerMetadata` — uses the
validated host for `issuer` and `*_endpoint`, **except**
`authorization_endpoint`: when the request came in via `SERVER_URL`
(API-only, no `/authorize` route), we keep that one pointed at the
default frontend base URL.
- `McpAuthGuard` — sets `WWW-Authenticate: Bearer
resource_metadata=\"<validatedBase>/.well-known/oauth-protected-resource\"`
on 401s, so the MCP client's follow-up discovery fetch lands on the same
host it started on.
## Security
- Workspace identity is already bound to the JWT via per-workspace
signing secrets (`jwtWrapperService.generateAppSecret(tokenType,
workspaceId)`). Host-aware discovery does not weaken that.
- Custom domains are only accepted once `isCustomDomainEnabled = true`
(i.e. after DNS verification), so an attacker can't register a
custom-domain mapping on a workspace and have discovery reflect it
before it's been proven.
- Unknown / spoofed Hosts fall through to the default base URL.
## Drive-by
Fixed a duplicate `DomainServerConfigModule` import in
`application-oauth.module.ts` while adding `WorkspaceDomainsModule`.
## Companion infra change required for custom domains
Customer custom domains (`crm.acme.com/mcp`) also require an
ingress-level fix to exclude `/mcp`, `/oauth`, and `/.well-known` from
the `/s\$uri` rewrite applied when `X-Twenty-Public-Domain: true`.
Shipping that in a twenty-infra PR (will cross-link here).
## Test plan
- [x] 14 new tests in
`WorkspaceDomainsService.getValidatedRequestBaseUrl` covering: missing
Host, SERVER_URL, base URL, FRONTEND_URL, workspace subdomain, unknown
subdomain fallback, enabled custom domain, disabled custom domain,
public domain, completely unrecognized host, lowercase coercion,
malformed Host, single-workspace mode fallback, DB throwing → fallback
- [x] New `oauth-discovery.controller.spec.ts` covering both endpoints
across api / app / workspace-subdomain / custom-domain hosts, plus
`cli_client_id` propagation
- [x] Rewrote `mcp-auth.guard.spec.ts` to cover `WWW-Authenticate` for
all four host types (api, workspace subdomain, custom domain, spoofed
fallback)
- [x] `yarn jest
--testPathPatterns=\"workspace-domains.service|oauth-discovery.controller|mcp-auth.guard\"`
→ 41/41 passing
- [x] `tsc --noEmit` clean on all modified files

`api.twenty.com/mcp`, `app.twenty.com/mcp`,

- Add a `pageLayoutId` foreign key to `CommandMenuItem`, allowing
command menu items to be scoped to a specific page layout instead of
being globally available
- Filter command menu items by the current page layout on the frontend.
Items with a `pageLayoutId` only appear when viewing that layout, while
items without one remain globally visible
- Create an effect to track the current page layout ID
- Include a seed example: a "Show Notification" command pinned to the

Add support for standalone pages: a new `PageLayout` type
(`STANDALONE_PAGE`) that can be rendered independently at
`/page/:pageLayoutId`, not tied to any record or object context.
- New `STANDALONE_PAGE` page layout type
- New `PAGE_LAYOUT` navigation menu item type: adds a `pageLayoutId`
foreign key to `NavigationMenuItemEntity`, allowing sidebar items to
link directly to standalone pages
- New `GLOBAL_OBJECT_CONTEXT` command menu availability type: separates
object-context-dependent commands (Create Record, Import, Export, See
Deleted, Create View, Hide Deleted) from truly global ones, so
standalone pages only show relevant commands
- Frontend routing & rendering: adds a `/page/:pageLayoutId` route with
its own page component, header, and command menu
- Widget rendering refactor
- Instance commands: two fast 1.22 migrations: `pageLayoutId` column +
`STANDALONE_PAGE` enum, and `GLOBAL_OBJECT_CONTEXT` availability type
enum
- Workspace command: backfills existing command menu items from `GLOBAL`
to `GLOBAL_OBJECT_CONTEXT` where appropriate
- Dev seeds: adds a sample "Star History" standalone page with an iframe
widget for local development
## Summary
- Adds `isUnique?: boolean` to `RegularFieldManifest` in
`twenty-shared`, allowing SDK applications to declare unique constraints
on fields
- Updates the manifest-to-flat-field converter to read `isUnique` from
the manifest instead of hardcoding `false`
- Generates corresponding unique index metadata in
`computeApplicationManifestAllUniversalFlatEntityMaps` when a field has
`isUnique: true`, matching the behavior of the `CreateFieldInput` path
- Adds SDK-side validation rejecting `isUnique` on RELATION,
MORPH_RELATION, and FILES field types
- Adds integration test verifying manifest sync creates a unique index
for `isUnique` fields
- Adds SDK unit tests for `isUnique` validation on unsupported field
types
## Test plan
- [x] SDK unit tests: `defineField` accepts `isUnique: true` on TEXT,
rejects on RELATION and FILES
- [ ] Integration test: manifest sync with `isUnique: true` creates the
unique index in DB
- [ ] Verify `isUnique` defaults to `false` when not specified (backward
compatible)
- [ ] Verify standalone manifest fields (not nested in objects) also
generate unique indexes correctly
- removes pre-install function
- execute **asyncrhonously** post-install function at application

## Summary
- **Config as source of truth**: `~/.twenty/config.json` is now the
single source of truth for SDK authentication — env var fallbacks have
been removed from the config resolution chain.
- **Test instance support**: `twenty server start --test` spins up a
dedicated Docker instance on port 2021 with its own config
(`config.test.json`), so integration tests don't interfere with the dev
environment.
- **API key auth for marketplace**: Removed `UserAuthGuard` from
`MarketplaceResolver` so API key tokens (workspace-scoped) can call
`installMarketplaceApp`.
- **CI for example apps**: Added monorepo CI workflows for `hello-world`
and `postcard` example apps to catch regressions.
- **Simplified CI**: All `ci-create-app-e2e` and example app workflows
now use a shared `spawn-twenty-app-dev-test` action (Docker-based)
instead of building the server from source. Consolidated auth env vars
to `TWENTY_API_URL` + `TWENTY_API_KEY`.
- **Template publishing fix**: `create-twenty-app` template now
correctly preserves `.github/` and `.gitignore` through npm publish
(stored without leading dot, renamed after copy).
## Test plan
- [x] CI SDK (lint, typecheck, unit, integration, e2e) — all green
- [x] CI Example App Hello World — green
- [x] CI Example App Postcard — green
- [x] CI Create App E2E minimal — green
- [x] CI Front, CI Server, CI Shared — green
- Adds a payload JSON column to `CommandMenuItem` and introduces a
unified `NAVIGATION` engine component key that replaces all individual
GO_TO_* keys
- Navigation commands now use the payload to determine their target
(either an objectMetadataItemId or a path), making navigation commands
dynamic and eliminating the need for a hardcoded engine key per object
- Includes a 1.21 upgrade command (refactor-navigation-commands) that
migrates existing GO_TO_* items to NAVIGATION items with the appropriate
payload, and applies a CHECK constraint enforcing payload coherence

TODO: In a second PR, create the sync between object metadata items and
the navigation command menu items
- Object metadata item created or enabled -> Create navigation command
- Object metadata item deleted or disabled -> Delete associated
navigation command
In another PR:
- Allow `label`, `shortLabel` and `icon` to resolve the
`navigateToObjectMetadataItem` dynamically in their interpolation
instead of being hardcoded in the command menu item
- Make the icon dynamic in the command menu items as the label so that
we can resolve ${navigateToObjectMetadataItem.icon} at runTime -> This
way we won't need to keep update the command menu item icon when we
update the objectMetadataItem icon
- simplify the base application template
- remove --exhaustive option and replace by a --example option like in
next.js https://nextjs.org/docs/app/api-reference/cli
- Fix some bugs and logs
- add a post-card app in twenty-apps/examples/
## Summary
- **Make app-synced objects searchable**: `isSearchable` was hardcoded
to `false` and the `searchVector` field was missing the `GENERATED
ALWAYS AS (...)` expression, causing all records to have a `NULL` search
vector and be excluded from search results. Fixed by defaulting
`isSearchable` to `true` (configurable via the object manifest),
computing the `asExpression` from the label identifier field, and
allowing the update-field-action-handler to handle the `null` → defined
`asExpression` transition.
- **Make `isSearchable` updatable on an object**: The property had
`toCompare: false` in the entity properties configuration, so updates
via the API were silently ignored and never persisted. Fixed by setting
`toCompare: true`.
- Replace soft-deletion (deletedAt) with isActive boolean for
overridable entities (tabs, widgets, viewFieldGroups, viewFields).
Standard entities are deactivated (isActive: false) when removed from
update payloads, while custom entities are hard-deleted.
- When a viewFieldGroup is deactivated/deleted, its viewFields are
reassigned to the next section by position (or null if none remain).
- Add isActive: true filters to viewFieldGroup and viewField API queries
so deactivated entities are excluded from responses.
Next:
- fields-widget-upsert.service.ts should be refactored a bit
- Add restore logic
📄 Summary
This PR upgrades the nodemailer dependency to a secure version (≥ 8.0.4)
to fix a known SMTP command injection vulnerability
(GHSA-c7w3-x93f-qmm8).
🚨 Issue
The current version used in twenty-server (^7.0.11, resolved to 7.0.11 /
7.0.13) is vulnerable to SMTP command injection due to improper
sanitization of the envelope.size parameter.
This could allow CRLF injection, potentially enabling attackers to add
unauthorized recipients to outgoing emails.
🔍 Root Cause
The vulnerability originates from insufficient validation of
user-controlled input in the SMTP envelope, specifically the size field,
which can be exploited via crafted input containing CRLF sequences.
✅ Changes
Upgraded nodemailer to version ^8.0.4
Ensured compatibility with existing email sending logic
Verified that no breaking changes affect current usage
🔐 Security Impact
This update mitigates the risk of:
SMTP command injection
Unauthorized email recipient manipulation
Potential data leakage via crafted email payloads

## 1. The `twenty-client-sdk` Package (Source of Truth)
The monorepo package at `packages/twenty-client-sdk` ships with:
- A **pre-built metadata client** (static, generated from a fixed
schema)
- A **stub core client** that throws at runtime (`CoreApiClient was not
generated...`)
- Both ESM (`.mjs`) and CJS (`.cjs`) bundles in `dist/`
- A `package.json` with proper `exports` map for
`twenty-client-sdk/core`, `twenty-client-sdk/metadata`, and
`twenty-client-sdk/generate`
## 2. Generation & Upload (Server-Side, at Migration Time)
**When**: `WorkspaceMigrationRunnerService.run()` executes after a
metadata schema change.
**What happens in `SdkClientGenerationService.generateAndStore()`**:
1. Copies the stub `twenty-client-sdk` package from the server's assets
(resolved via `SDK_CLIENT_PACKAGE_DIRNAME` — from
`dist/assets/twenty-client-sdk/` in production, or from `node_modules`
in dev)
2. Filters out `node_modules/` and `src/` during copy — only
`package.json` + `dist/` are kept (like an npm publish)
3. Calls `replaceCoreClient()` which uses `@genql/cli` to introspect the
**application-scoped** GraphQL schema and generates a real
`CoreApiClient`, then compiles it to ESM+CJS and overwrites
`dist/core.mjs` and `dist/core.cjs`
4. Archives the **entire package** (with `package.json` + `dist/`) into
`twenty-client-sdk.zip`
5. Uploads the single archive to S3 under
`FileFolder.GeneratedSdkClient`
6. Sets `isSdkLayerStale = true` on the `ApplicationEntity` in the
database
## 3. Invalidation Signal
The `isSdkLayerStale` boolean column on `ApplicationEntity` is the
invalidation mechanism:
- **Set to `true`** by `generateAndStore()` after uploading a new client
archive
- **Checked** by both logic function drivers before execution — if
`true`, they rebuild their local layer
- **Set back to `false`** by `markSdkLayerFresh()` after the driver has
successfully consumed the new archive
Default is `false` so existing applications without a generated client
aren't affected.
## 4a. Logic Functions — Local Driver
**`ensureSdkLayer()`** is called before every execution:
1. Checks if the local SDK layer directory exists AND `isSdkLayerStale`
is `false` → early return
2. Otherwise, cleans the local layer directory
3. Calls `downloadAndExtractToPackage()` which streams the zip from S3
directly to disk and extracts the full package into
`<tmpdir>/sdk/<workspaceId>-<appId>/node_modules/twenty-client-sdk/`
4. Calls `markSdkLayerFresh()` to set `isSdkLayerStale = false`
**At execution time**, `assembleNodeModules()` symlinks everything from
the deps layer's `node_modules/` **except** `twenty-client-sdk`, which
is symlinked from the SDK layer instead. This ensures the logic
function's `import ... from 'twenty-client-sdk/core'` resolves to the
generated client.
## 4b. Logic Functions — Lambda Driver
**`ensureSdkLayer()`** is called during `build()`:
1. Checks if `isSdkLayerStale` is `false` and an existing Lambda layer
ARN exists → early return
2. Otherwise, deletes all existing layer versions for this SDK layer
name
3. Calls `downloadArchiveBuffer()` to get the raw zip from S3 (no disk
extraction)
4. Calls `reprefixZipEntries()` which streams the zip entries into a
**new zip** with the path prefix
`nodejs/node_modules/twenty-client-sdk/` — this is the Lambda layer
convention path. All done in memory, no disk round-trip
5. Publishes the re-prefixed zip as a new Lambda layer via
`publishLayer()`
6. Calls `markSdkLayerFresh()`
**At function creation**, the Lambda is created with **two layers**:
`[depsLayerArn, sdkLayerArn]`. The SDK layer is listed last so it
overwrites the stub `twenty-client-sdk` from the deps layer (later
layers take precedence in Lambda's `/opt` merge).
## 5. Front Components
Front components are built by `app:build` with `twenty-client-sdk/core`
and `twenty-client-sdk/metadata` as **esbuild externals**. The stored
`.mjs` in S3 has unresolved bare import specifiers like `import {
CoreApiClient } from 'twenty-client-sdk/core'`.
SDK import resolution is split between the **frontend host** (fetching &
caching SDK modules) and the **Web Worker** (rewriting imports):
**Server endpoints**:
- `GET /rest/front-components/:id` —
`FrontComponentService.getBuiltComponentStream()` returns the **raw
`.mjs`** directly from file storage. No bundling, no SDK injection.
- `GET /rest/sdk-client/:applicationId/:moduleName` —
`SdkClientController` reads a single file (e.g. `dist/core.mjs`) from
the generated SDK archive via
`SdkClientGenerationService.readFileFromArchive()` and serves it as
JavaScript.
**Frontend host** (`FrontComponentRenderer` in `twenty-front`):
1. Queries `FindOneFrontComponent` which returns `applicationId`,
`builtComponentChecksum`, `usesSdkClient`, and `applicationTokenPair`
2. If `usesSdkClient` is `true`, renders
`FrontComponentRendererWithSdkClient` which calls the
`useApplicationSdkClient` hook
3. `useApplicationSdkClient({ applicationId, accessToken })` checks the
Jotai atom family cache for existing blob URLs. On cache miss, fetches
both SDK modules from `GET /rest/sdk-client/:applicationId/core` and
`/metadata`, creates **blob URLs** for each, and stores them in the atom
family
4. Once the blob URLs are cached, passes them as `sdkClientUrls`
(already blob URLs, not server URLs) to `SharedFrontComponentRenderer` →
`FrontComponentWorkerEffect` → worker's `render()` call via
`HostToWorkerRenderContext`
**Worker** (`remote-worker.ts` in `twenty-sdk`):
1. Fetches the raw component `.mjs` source as text
2. If `sdkClientUrls` are provided and the source contains SDK import
specifiers (`twenty-client-sdk/core`, `twenty-client-sdk/metadata`),
**rewrites** the bare specifiers to the blob URLs received from the host
(e.g. `'twenty-client-sdk/core'` → `'blob:...'`)
3. Creates a blob URL for the rewritten source and `import()`s it
4. Revokes only the component blob URL after the module is loaded — the
SDK blob URLs are owned and managed by the host's Jotai cache
This approach eliminates server-side esbuild bundling on every request,
caches SDK modules per application in the frontend, and keeps the
worker's job to a simple string rewrite.

- Makes engineComponentKey non-nullable on CommandMenuItem. Adds two new
engine component keys: TRIGGER_WORKFLOW_VERSION and
FRONT_COMPONENT_RENDERER to cover the former standalone cases.
- Unifies the previously separated engine, front component and workflow
runners into a single `CommandRunner` component with a unified
`useMountCommand` hook that handles all command types.
## Summary
- File serving endpoints (`GET file/:fileFolder/:id` and `GET
public-assets/...`) were piping S3/local file streams directly to the
response without any HTTP headers, allowing a stored XSS attack via
uploaded HTML files rendered inline on the CRM origin.
- Adds `Content-Type`, `Content-Disposition`, and
`X-Content-Type-Options: nosniff` headers to all file serving responses.
Only known-safe MIME types (images, PDF, plain text, audio, video) are
served inline; everything else (HTML, SVG, XML, etc.) forces
`Content-Disposition: attachment` to trigger download instead of
rendering.
- New `setFileResponseHeaders` utility with an explicit allowlist of
inline-safe MIME types.
## Test plan
- [x] Unit tests pass (9 tests including 2 new ones: header assertions
and attachment-disposition for HTML)
- [x] Lint clean (`lint:diff-with-main`)
- [x] Typecheck clean (`nx typecheck twenty-server`)
- [ ] Manual: upload an HTML file via `uploadWorkflowFile`, access the
returned URL — should download instead of rendering
- [ ] Manual: upload a PNG image, access the URL — should render inline
with correct `Content-Type: image/png`
- [ ] Manual: verify `X-Content-Type-Options: nosniff` header is present
on all file responses

## Summary
- Replaces per-provider TypeScript constant files
(`openai-models.const.ts`, `anthropic-models.const.ts`, etc.) with a
single `ai-providers.json` catalog as the source of truth
- Adds runtime model discovery via AI SDK for self-hosted providers,
with `models.dev` enrichment for pricing/capabilities
- Introduces composite model IDs (`provider/modelId`) for canonical,
conflict-free identification
- Simplifies provider configuration: API keys are injected from
environment variables (e.g., `OPENAI_API_KEY`)
- Adds admin panel UI for provider management (add/remove/test), model
discovery, recommended model configuration, and default fast/smart model
selection per workspace
- Removes deprecated config variables (`AI_DISABLED_MODEL_IDS`,
`AUTO_ENABLE_NEW_AI_MODELS`, etc.)
- Adds database migration for composite model ID format
## Test plan
- [ ] Server typecheck passes
- [ ] Frontend typecheck passes
- [ ] Server unit tests pass
- [ ] Frontend unit tests pass
- [ ] CI pipeline green
- [ ] Admin panel AI tab loads correctly
- [ ] Provider discovery works for configured providers
- [ ] Model recommendation toggles persist
- [ ] Default fast/smart model selection works
Made with [Cursor](https://cursor.com)
- Adds template variable interpolation (`${...}`) to command menu item
labels and short labels, enabling dynamic text like `Create new
${capitalize(objectMetadataItem.labelSingular)}` instead of static
`Create new record`.
- Supports `capitalize` and `lowercase` transform functions within
template expressions.
## Summary
- Adds a `color` column to `ObjectMetadataEntity` with full GraphQL
support so object icon colors are persisted at the metadata level
- Adds a `type` column to `NavigationMenuItemEntity` (enum: `OBJECT`,
`VIEW`, `FOLDER`, `LINK`, `RECORD`) replacing field-based type inference
- Updates frontend to read object colors from `objectMetadata.color`
(falling back to standard defaults) in the sidebar nav, record index
header, and record show breadcrumb
- Simplifies `NavigationMenuItemIcon` color resolution via
`getEffectiveNavigationMenuItemColor` util
## Color rules
| Item type | Color source | Editable in sidebar? |
|-----------|-------------|---------------------|
| **Object** | `objectMetadata.color` | Yes — persisted to
`objectMetadata.color` on Save |
| **Folder** | `navigationMenuItem.color` | Yes |
| **Link** | Fixed default (`DEFAULT_NAVIGATION_MENU_ITEM_COLOR_LINK`) |
No |
| **View** | `objectMetadata.color` (from the parent object) | No |
| **Record** | None | No |
- **Object** items represent the whole object (e.g. "Companies") and
point to the INDEX view. Changing their color updates
`objectMetadata.color` via `useSaveObjectMetadataColorsFromDraft`.
- **View** items represent specific non-INDEX views. Their color comes
from the parent object's metadata (read-only).
- Only **folders** store their color on `navigationMenuItem.color` —
enforced by `hasNavigationMenuItemOwnColor` util.
- `getEffectiveNavigationMenuItemColor` returns `objectColor` for both
OBJECT and VIEW items, folder's own color for folders, and the fixed
default for links.
## NavigationMenuItemType enum
- Shared enum created in `twenty-shared` with values: `OBJECT`, `VIEW`,
`FOLDER`, `LINK`, `RECORD`
- Registered as a GraphQL enum on the backend
- Replaces string literals across entity, DTOs, input, converters, and
frontend hooks
- Migration backfills existing rows: INDEX views → `OBJECT`, non-INDEX
views → `VIEW`, based on join with the view table
## Design decisions
- **OBJECT vs VIEW distinction**: Items pointing to INDEX views are
typed as `OBJECT` (represent the whole object, color editable). Items
pointing to non-INDEX views are typed as `VIEW` (specific view, color
read-only from parent object).
- **Dual color storage**: `navigationMenuItem.color` is preserved for
folders only. Objects use `objectMetadata.color` as their source of
truth.
- **Type discriminator**: The `type` column replaces field-based
inference (checking `viewId`, `link`, `targetRecordId` presence) with an
explicit enum, simplifying `isNavigationMenuItemLink` /
`isNavigationMenuItemFolder` to simple `item.type ===` checks.
- **No settings page color picker**: Object color editing is done from
the sidebar edit panel, not the data model settings page.
## Test plan
- [ ] Verify objects display their default standard colors in the
sidebar
- [ ] Verify object color editing works in the sidebar edit panel
(persists to objectMetadata.color)
- [ ] Verify folder color editing works in the sidebar edit panel
- [ ] Verify views, links, and records do NOT show a color picker in the
sidebar edit panel
- [ ] Run `npx nx typecheck twenty-front` and `npx nx typecheck
twenty-server`
- [ ] Verify the database migrations add `color` to `objectMetadata` and
`type` to `navigationMenuItem`

## Summary
This PR implements OAuth 2.0 Dynamic Client Registration (RFC 7591) and
OAuth 2.0 Protected Resource Metadata (RFC 9728) support, enabling
third-party applications to dynamically register as OAuth clients
without manual configuration.
## Key Changes
### OAuth Dynamic Client Registration
- **New Controller**: `OAuthRegistrationController` at `POST
/oauth/register` endpoint
- Validates client metadata according to RFC 7591 specifications
- Enforces PKCE-only public client model (no client secrets)
- Supports only `authorization_code` grant type and `code` response type
- Rate limits registrations to 10 per hour per IP address
- Returns `client_id` and registration metadata in response
- **Input Validation**: `OAuthRegisterInput` DTO with constraints on:
- Client name (max 256 chars)
- Redirect URIs (max 20, validated for security)
- Grant types, response types, scopes, and auth methods
- Logo and client URIs (max 2048 chars)
- **Discovery Endpoint Update**: Added `registration_endpoint` to OAuth
discovery metadata
### Stale Registration Cleanup
- **Cleanup Service**: Automatically removes OAuth-only registrations
older than 30 days that have no active installations
- **Cron Job**: Runs daily at 02:30 AM UTC with batch processing (100
records per batch)
- **CLI Command**: `cron:stale-registration-cleanup` to manually trigger
cleanup
### MCP (Model Context Protocol) Authentication
- **New Guard**: `McpAuthGuard` implements RFC 9728 compliance
- Wraps JWT authentication with proper error responses
- Returns `WWW-Authenticate` header with protected resource metadata URL
on 401
- Enables OAuth-protected MCP endpoints
### Protected Resource Metadata
- **New Endpoint**: `GET /.well-known/oauth-protected-resource` (RFC
9728)
- Advertises MCP resource as OAuth-protected
- Lists supported scopes and bearer token methods
- Enables OAuth clients to discover authorization requirements
### Application Registration Updates
- **New Source Type**: `OAUTH_ONLY` enum value for OAuth-only
registrations
- **Install Service**: Skips artifact installation for OAuth-only apps
(no code artifacts)
### Frontend Updates
- **Authorization Page**: Support both snake_case (standard OAuth) and
camelCase (legacy) query parameters
- `client_id` / `clientId`
- `code_challenge` / `codeChallenge`
- `redirect_uri` / `redirectUrl`
## Implementation Details
- **Rate Limiting**: Uses token bucket algorithm with 10 registrations
per 3,600,000ms window per IP
- **Scope Validation**: Requested scopes are capped to allowed OAuth
scopes; defaults to all scopes if not specified
- **Redirect URI Validation**: Uses existing `validateRedirectUri`
utility for security
- **Cache Headers**: Registration responses include `Cache-Control:
no-store` and `Pragma: no-cache`
- **Batch Processing**: Cleanup operations process 100 records at a time
to avoid memory issues
- **Grace Period**: 30-day grace period before cleanup to allow time for
client activation

## Context
This PR introduces overrides for view fields which will be useful for
page layout FIELDS widgets fields position/groups/visibility override +
restore logic.
## PR Description
In the process of migrating all the existing commands to the backend, we
stumbled across a couple of problems that made us reconsider the full
migration. This PR introduces a way for command menu items to bypass
front components and to directly reference a frontend component from
twenty front.
It:
- Introduces a `engineFrontComponentKey` field on `CommandMenuItem` as
an alternative to `frontComponentId` and `workflowVersionId`, allowing
command menu items to reference frontend components by key directly
rather than requiring a FrontComponent entity
- Updates the DB constraint to allow exactly one of `workflowVersionId`,
`frontComponentId`, or `engineFrontComponentKey`
### All standard command menu items from the frontend which use
`standardFrontComponentKey`
These are all commands that execute a GraphQL query or a mutation.
Two mains concerned have been raised that made us go with this
(temporary) architecture instead:
- If those commands are part of the standard application, they can only
alter objects from that application and not custom objects.
- We would need to implement a way to trigger optimistic rendering from
the front components, which might take some time to implement.
List:
- Create new record
- Delete (single record)
- Delete records (multiple)
- Restore record
- Restore records (multiple)
- Permanently destroy record
- Permanently destroy records (multiple)
- Add to favorites
- Remove from favorites
- Merge records
- Duplicate Dashboard
- Save Dashboard
- Save Page Layout
- Activate Workflow
- Deactivate Workflow
- Discard Draft (workflow)
- Test Workflow
- Tidy up workflow
- Duplicate Workflow
- Stop (workflow run)
- Use as draft (workflow version)
