PlanetScale PostgreSQL create role service token create_production_branch_password pscale role create
💡 Result:
<search_synthesis>
To manage roles and credentials in PlanetScale for PostgreSQL, you use the pscale role CLI command, not a create_production_branch_password command [1][2]. ### Creating Roles with the PlanetScale CLI The pscale role create command is the standard way to create user-defined roles for a PostgreSQL database branch [1][2]. Command syntax: pscale role create <database> <branch> <name> [flags] Example: pscale role create my-database main api-user --inherited-roles pg_read_all_data --ttl 24h Key flags: --inherited-roles: A comma-separated list of roles to inherit from (e.g., pg_read_all_data, postgres) [2]. --ttl: Defines how long the role is valid (e.g., 30m, 24h) [2]. ### Service Tokens and Permissions If you are automating the creation of roles (for example, in CI/CD pipelines), you must use a Service Token with the appropriate permissions [3]. To use the API or CLI to create roles, the service token requires specific access permissions [4]. For roles, the relevant service token access is: create_production_branch_password [4] To grant this permission to a service token via the CLI, you would use: pscale service-token add-access <TOKEN_ID> create_production_branch_password --database <DATABASE_NAME> [5][6] In summary, create_production_branch_password is a permission scope granted to a Service Token, while pscale role create is the command used to actually generate the database credentials [4][2].

Add a role-creation access for the restored production branch.
After the restore becomes ready, withBranchConnection runs pscale role create through createCredential. A nonzero exit calls fail before verification. PlanetScale requires one of create_production_branch_password, create_production_read_only_branch_password, or create_branch_password for this operation. The listed accesses include none of these. Add create_production_branch_password for the production restore path.

site:planetscale.com/docs service token write_service_tokens update existing token creator organization administrator
💡 Result:
<search_synthesis>
In the context of PlanetScale, the write_service_tokens permission is required to create and update service tokens [1][2]. Management of these tokens, including updating their permissions (grants), is typically restricted to organization administrators [3][4]. Key details regarding service token management: Permissions for managing tokens: The ability to manage service tokens (create, view, or delete) and their associated access grants (create, view, update, or delete) is reserved for organization administrators [4]. Updating existing tokens: While write_service_tokens is the designated permission for creating and updating service tokens [1], modifications to the specific permissions (access grants) assigned to a token are managed separately under "Manage service token grants" permissions [4]. In the PlanetScale dashboard, you can modify permissions by opening the service token's settings and selecting "Edit permissions" or "Add/Delete access" [3]. CLI and API limitations: Service token management commands (such as those for updating permissions) are generally unavailable when authenticated using a service token itself [3][5]. To perform these management tasks, you must authenticate via the PlanetScale CLI using user-level credentials (pscale auth login) or use the authorized API endpoints [3][5]. Service tokens are intended to provide scoped access to resources rather than managing the administrative aspects of the organization's security infrastructure [3][5].

💡 Result:
<search_synthesis>
In PlanetScale, write_service_tokens is an organization-level permission that allows a service token to create and update other service tokens within an organization [1]. Regarding the management of service token grants, access is controlled by specific organizational roles [2]: 1. Administrator Role: Organization administrators have the authority to manage both service tokens (create, view, delete) and service token grants (create, view, update, delete) [2]. 2. Creating and Modifying Grants: Service token grants define the specific permissions a token has, either at the organization level or the database level [3][4]. These can be managed via the PlanetScale dashboard or the PlanetScale CLI [3][4]. - Adding Access: To grant permissions to a service token, use the CLI command: pscale service-token add-access <SERVICE_TOKEN_ID> <ACCESS_PERMISSION> [--database <DB_NAME>] [3][4]. - Modifying Access: Existing permissions can be updated by selecting "Edit permissions" in the dashboard or by using the add-access and delete-access CLI commands to adjust the scope [3][4]. Note that operations to create or manage service tokens and their grants must be performed under an authenticated user session (e.g., pscale auth login), as there is no service-token CLI path for these specific administrative actions [5].

site:planetscale.com/docs/api/reference service token access add update authorization write_service_tokens grant
💡 Result:
<search_synthesis>
In the context of the PlanetScale platform, write_service_tokens is a specific granular permission required to authorize actions related to creating and updating service tokens [1]. When configuring service tokens, you can grant them various access permissions to interact with the PlanetScale API [1]. The write_service_tokens permission specifically allows a token to perform create and update operations on other service tokens within an organization [1]. For security and API operations, PlanetScale requires that any service token used to call an API endpoint must possess the specific access permission associated with that endpoint [1]. For example, using the API to create a new service token requires the caller to have the write_service_tokens permission [2]. Other related permissions for managing service tokens include read_service_tokens (for retrieving information) and delete_service_tokens (for removing tokens) [1]. You can assign these permissions when creating or editing a service token in the PlanetScale interface [1].

site:planetscale.com/docs/security/access-control "Manage service token grants" Member Analyst Administrator
💡 Result:
<search_synthesis>
The roles of Member, Analyst, and Administrator represent different levels of access control within the PlanetScale platform, specifically regarding the management of service tokens and their associated grants [1]. According to PlanetScale documentation, these roles determine a user's ability to perform administrative tasks, such as creating, viewing, updating, or deleting service tokens and their grants [1]. - Administrator: Typically holds the highest level of access within an organization or database, allowing for the management of service tokens and service token grants, as well as managing members [1]. - Analyst and Member: These roles have more restricted access compared to an Administrator. Their specific permissions regarding service token grants depend on the organization's access control configuration [1]. Organization Administrators are required to modify member roles and manage overall access permissions [1]. For specific operations, such as creating production service token grants, permissions are strictly defined based on the role assigned to the user [1].

…anch A restore without an explicit cluster size lands as a PS-10 branch flagged production: true, which the CI token can only delete with the same accesses that could delete main, and PlanetScale cannot demote a Postgres restore branch afterwards. A PS_DEV restore is a development branch: delete_branch and delete_branch_password suffice, and it is the cheapest size. Verified end to end as the CI token: restore, verify, role revoke, branch delete.
