Exploring the schema

The describe command introspects the schema downloaded from the server and prints, in human-readable form, what objects exist, what fields and variants each one has, what enums are defined, and which list-level filters and sort options are supported.

It is the recommended starting point when working with an unfamiliar deployment or when designing a configuration plan for bulk apply.

Listing every object

Run describe with no arguments to get a sorted listing of all management objects (those whose JMAP names start with x:):

stalwart-cli describe

Account                 Defines a user or group account for authentication and email access.
AccountPassword         Password-based authentication credential. [singleton]
AccountSettings         Configures default account settings for locale and encryption. [singleton]
AcmeProvider            Defines an ACME provider for automatic TLS certificate management.
Action                  Defines server management actions such as reloads, troubleshooting and cache operations.
AddressBook             Configures address book and contact storage settings. [singleton]
...
Domain                  Defines an email domain and its DNS, DKIM, and TLS certificate settings.
...
SystemSettings          Server-wide configuration. [singleton]
...

The [singleton] tag identifies objects that have exactly one instance per server (configuration objects). Singletons cannot be created or destroyed (only updated). See the Updating objects page for details on how singleton ids work.

Inspecting a single object

Pass the object name (with or without the x: prefix, case-insensitive) to get its full description:

stalwart-cli describe domain

Domain
  Defines an email domain and its DNS, DKIM, and TLS certificate settings.

Fields:
    aliases                set<string<string>>  mutable
        List of additional domain names that are aliases of this domain
    allowRelaying          boolean  mutable
        Whether to allow relaying for non-local recipients, useful in split delivery scenarios
    catchAllAddress        string<emailAddress>?  mutable
        Catch-all email address that receives messages addressed to unknown local recipients
    certificateManagement  object<CertificateManagement>  mutable
        Whether TLS certificates for this domain are managed manually or automatically by an ACME provider
    createdAt              datetime  server-set
        Creation date of the domain
    description            string<string>?  mutable
        Description of the domain
    ...
    name                   string<string>  mutable
        Domain name

Filters:
    text            text        Text
    name            text        Name
    memberTenantId  id<Tenant>  Tenant

The output has up to four sections:

• Header: object name, optional [singleton] tag, description.
• Fields (single-schema objects): every property the server exposes, with type, mutability (mutable, immutable, server-set), and a description.
• Variants (multi-variant objects): each @type discriminator value with a label, followed by that variant's fields. See the next section.
• Filters: what --where keys query accepts for this object. The kind (text, integer, date, enum, id<Object>) hints at the expected value shape.
• Sort by: the property names accepted by JMAP sort (omitted when none are declared).

A ? after a type indicates the field is nullable (null is an accepted value).

Multi-variant objects

Some objects are multi-variant: each instance has an @type field that selects one of several distinct shapes. Account is the canonical example (variants User and Group):

stalwart-cli describe account

Account
  Defines a user or group account for authentication and email access.

  Variants:
    User — User account
      Fields:
        aliases           list<EmailAlias>  mutable
            List of email aliases for the account
        createdAt         datetime  server-set
        ...
        name              string<string>  mutable
            Name of the account, typically an email address local part.
        domainId          id<Domain>  mutable
            Identifier for the domain this account belongs to.
        ...
    Group — Group account
      Fields:
        ...

Filters:
    text            text               Text
    name            text               Name
    domainId        id<Domain>         Domain
    memberGroupIds  id<Account/Group>  Group
    memberTenantId  id<Tenant>         Tenant

When creating a multi-variant object, the @type must be supplied (either via the Object/Variant shorthand or as an explicit field). Filters are always merged across the parent object's list and any view lists that target it, and deduplicated by field name.

Inspecting an enum

Enum names can be passed to describe exactly like object names. The lookup tries objects first, then enums, so the command does not need to be told which kind of name was supplied:

stalwart-cli describe AccountType

AccountType  (enum)

  Variants:
    User   User account
    Group  Group account

Enums whose variants carry a color (for example log severity levels) are rendered with their colors in interactive terminals:

stalwart-cli describe TracingLevel

TracingLevel  (enum)

  Variants:
    error  Error
    warn   Warning
    info   Info
    debug  Debug
    trace  Trace

Tips

• The output is purely descriptive (no requests are issued for individual objects). Run it freely to learn the schema before designing an apply plan.
• For very large enums (hundreds of variants), describe on an object that references one shows enum (see <enumName>) instead of inlining the values. Run describe <enumName> to see them.
• Field type summaries use compact notation: string<format>, number<format>, set<scalar>, list<embedded>, map<key, value>, id<RefObject>. The ? suffix marks nullable fields.
