Fetch all Databases.

• include=tables means we should hydrate the Tables belonging to each DB. Default: false.

• include=schemas hydrates a :schemas list on each DB (only schemas with visible tables the current user can read), matching the per-DB /api/database/:id/schemas response. Lets clients avoid N round-trips when populating a database/schema picker.

• saved means we should include the saved questions virtual database. Default: false.

• include_editable_data_model will only include DBs for which the current user has data model editing permissions. (If include=tables, this also applies to the list of tables in each DB). Granting those permissions to non-admins requires Enterprise Edition code and the advanced-permissions feature; without both, this is admin-only.

• exclude_uneditable_details will only include DBs for which the current user can edit the DB details. Has no effect unless Enterprise Edition code is available and the advanced-permissions feature is enabled.

• include_only_uploadable will only include DBs into which Metabase can insert new data.

• include_stubs includes stub DBs, which serialization creates for missing databases. Default: false.

• can-query will only include DBs for which the current user has query permissions. Default: false.

Independently of these flags, the implementation of [[metabase.models.interface/to-json]] for :model/Database in [[metabase.warehouses.models.database]] uses the implementation of [[metabase.models.interface/can-write?]] for :model/Database in [[metabase.warehouses.models.database]] to exclude the details field, if the requesting user lacks permission to change the database details.
