# Which Problems Are Solved
ZITADEL cannot currently be used as an OAuth 2.0 Authorization Server by
clients that need to register themselves at runtime:
- There is no [OAuth 2.0 Dynamic Client Registration (RFC
7591)](https://datatracker.ietf.org/doc/html/rfc7591) endpoint, and no
`registration_endpoint` is advertised in the discovery document.
- This blocks [Model Context Protocol
(MCP)](https://modelcontextprotocol.io) clients (Claude Desktop,
claude.ai, Cursor, the MCP SDKs), whose OAuth 2.1 authorization profile
expects an Authorization Server that supports dynamic client
registration. They self-register before any user context exists and only
then start the authorization code + PKCE flow.
# How the Problems Are Solved
## Control plane: instance security settings
No feature flag and no runtime config. A
`DynamicClientRegistrationSettings` message is nested under the instance
`SecuritySettings` in `settings/v2`, next to `embedded_iframe` and
`enable_impersonation`:
| `enabled` | `allow_unauthenticated` | Behaviour |
| --- | --- | --- |
| `false` (default) | — | `POST /oauth/v2/register` returns `404`,
`registration_endpoint` absent from discovery |
| `true` | `false` (default) | Token-gated registration, client homed in
the token's organization |
| `true` | `true` | Open registration for MCP hosts, client homed in the
instance default organization |
Both values are carried on `authz.Instance` and loaded with the
instance, exactly like `EnableImpersonation`, so the discovery document
and the endpoint read them per request without an extra query.
`allow_unauthenticated` implies `enabled` in both implementations, so a
single setting closes the endpoint.
Adding the two columns bumps the projection table to
`projections.security_policies3`, following what the impersonation
setting did for `security_policies2`.
## Authorization: a dedicated permission, not `project.app.write`
- New org-scoped permission **`project.app.register_dynamic`**, granted
by default to `ORG_OWNER`, `IAM_OWNER` and `IAM_ORG_MANAGER` — in both
`InternalAuthZ` and `SystemAuthZ`, mirroring where `project.app.write`
already lives.
- New built-in role **`ORG_DYNAMIC_CLIENT_REGISTRAR`** carrying only
that permission, so a service user can self-register clients without
gaining write access to the organization's existing applications.
- Open mode (`allow_unauthenticated = true`) requires no token and no
permission: that is the MCP self-register path.
- A valid token whose user lacks the permission is answered with **`403
insufficient_scope`** (RFC 6750 §3.1) rather than `401 invalid_token`,
so a caller can tell "your token is bad" from "your token may not do
this". `verifyAccessToken` also reports invalid tokens as permission
denied, so the authorization failure is marked explicitly to keep the
two apart.
The check runs once, at the endpoint, right after the token is verified
and before any state is created, so it also gates the auto-provisioning
of the organization's DCR project. The permission itself lives in the
command layer next to the others
(`Commands.CheckPermissionRegisterDynamicClient`). As the OIDC endpoints
are not behind the authorization interceptor, the caller identity is
derived from the verified token, the way token exchange does for the
impersonating actor.
## Registration itself
- **Registered clients are ordinary OIDC applications.** The endpoint
reuses the existing application-creation events
(`NewApplicationAddedEvent` and `NewOIDCConfigAddedEvent`), so the whole
token, authorization and introspection flow keeps working unchanged.
They are stored in a dedicated, auto-provisioned project named `ZITADEL
DCR` per organization (name lookup), so they do not pollute the
`IAMProject` or other projects.
- Input is validated with the existing `GetOIDCV1Compliance` rules;
`private_key_jwt` and `jwks`/`jwks_uri` are rejected with
`invalid_client_metadata`.
- **Endpoint wiring without forking the library.** `NewServer` calls
`op.RegisterServer` instead of `op.RegisterLegacyServer`, so the new
route can be added through the same `op.WithSetRouter` hook as the
authorize callback. `op.RegisterLegacyServer` appends a middleware after
the caller options, which chi forbids once a route has been registered;
`op.NewIssuerInterceptor` reproduces the issuer middleware it would
otherwise add. The `/oauth/v2` routing prefix is unchanged.
# Additional Changes
- **`application_type` inference for custom-scheme redirects** (last
commit, isolated). `application_type` is an OpenID Connect member; RFC
7591 does not define it, so clients that only implement RFC 7591 omit
it. Native MCP hosts doing so register custom-scheme redirect URIs,
which ZITADEL reserves for native applications, and the OIDC default of
`web` rejected them with `invalid_redirect_uri`. Inference is limited to
custom schemes and to an absent `application_type`, so every request
accepted today keeps its current application type and auth method — an
`http` loopback redirect still yields a web application. Happy to drop
this commit if you would rather keep it out of this PR.
- **Docs**: a Dynamic Client Registration integration guide, a
`registration_endpoint` section on the OpenID Connect endpoints page,
and the new role in the administrators table (plus its description in
the Console translations).
# Additional Context
- Part of #9810. This is **Phase 1 (DCR)**; #12315 adds RFC 7592 and
#12316 adds CIMD, both stacked on this branch and rebased once this
lands.
- Implements the control-plane and authorization model requested in the
review of this PR, itself a refinement of the direction in
https://github.com/zitadel/zitadel/issues/9810#issuecomment-4891176997.
- **Out of scope (deliberately)**: RFC 7592, CIMD, persisting free-form
metadata (`logo_uri`, `contacts`, and similar), and `private_key_jwt` /
`jwks_uri` (rejected cleanly). No new event types.
- Follow-ups explicitly left out, per the review: DCR client lifecycle
and richer audit, consent and custom scopes, JWT / `aud` (RFC 8707), and
RFC 8414 AS metadata (currently absent from both ZITADEL and
`zitadel/oidc`).
# Which Problems Are Solved
This PR implements the endpoints listed in #10445 using relational
tables.
- [x] UpdateOrganization
- [x] ListOrganizations
- [x] DeleteOrganization
- [x] DeactivateOrganization
- [x] ActivateOrganization
# How the Problems Are Solved
- **UpdateOrganization:** Implemented logic for `Validate()`,
`Execute()` and `Events()`. On CQRS side, updating an organization emits
events related to the organization and its domains. Separate commanders
have been made for the domain events so that their logic is run
accordingly and we keep separation of concerns. Implementation of the
domains is left to its own ticket.
Because some domain-related data is changed during the organization
update, its original values are saved as pointers inside
[UpdateOrgCommand](https://github.com/zitadel/zitadel/blob/4f87cd8d0cfd75f290aa13c342e4939cecebef73/backend/v3/domain/org_update.go#L20).
These variables will be then used as input for the domain commanders
(that will run after the update organization one).
- **ListOrganizations:** Implemented logic for `Validate()`,
`Execute()`. Utility methods have been made to parse the input queries.
This commander is used both by the v2 and v2beta endpoint, so a
translation layer has been put in place to translate all v2beta requests
into v2. The commander strictly handles v2 request only.
The translation layer between v2beta and v2 APIs was made so to make it
simple to remove it once the v2beta APIs will be removed (a simple
deletion should suffice). A `converter` package [is
shipped](https://github.com/zitadel/zitadel/blob/4f87cd8d0cfd75f290aa13c342e4939cecebef73/backend/v3/api/org/v2/convert/README.md#L5)
as well with instruction for removal. TODOs have been put in place all
over the code to indicate that the related piece of code needs to be
removed once v2beta -> v2 transition is complete.
- **DeleteOrganization:** Implemented logic for `Validate()`,
`Execute()` and `Events()`. The `Events()` method is mostly incomplete
as it requires a lot of data that is currently not retrievable due to
the lack of their relational tables.
- **DeactivateOrganization** and **ActivateOrganization**: Implemented
logic for `Validate()`, `Execute()` and `Events()`. No notable remarks.
👉 All endpoints return matching errors to the CQRS counterpart: this way
allows re-using the integration tests and
👉 All endpoints have been unit-tested through DB mocking
👉 A bunch of TODOs have been put in place for future reworks that are
needed (e.g. `Update()` method on repository should also return a
timestamp)
# Additional Changes
- A test utility method to allow mocking query options have been made.
This was necessary because `database.QueryOption` is a function and the
only comparison possible with functions is `nil` check. So, to mock
this, `database.QueryOption` is converted first to `database.QueryOpts`.
See 2276742adaef1998ea4844e1f0dca2079e45ccfb
- A `BaseCommand` has been created with the idea to collect methods that
are going to be needed by other commands. For the moment, it only offers
a method to convert query text operations from gRPC to `domain` model.
See bb85456dd101282fa76d2e2ad165eed4c8ef61b9
- SQL operations have been reworked to allow for queries using
`ContainsIgnoreCase`, `EndsWithIgnoreCase` and other `IgnoreCase`
operations. This change is pending approval and might be reworked. See
https://github.com/zitadel/zitadel/pull/10704#discussion_r2392886177
# Additional Context
`UpdateOrganization` is partially working because the logic for handling
domain updates is not done (there is only a draft of the commanders to
showcase the call chain). See
https://github.com/zitadel/zitadel/pull/10704#discussion_r2356143178
Permissions are not implemented as they are missing. See
