Install Jentic One Beta

Connect the AWS Single Sign-On Admin to your agent

Jentic One is a self-hosted execution layer for AI agents. It lets your agent call the AWS Single Sign-On Admin, or any other public or private API you need. You set the rules, the agent never sees your credentials, and every call is logged.

Two steps, two machines. Install the instance in a safe environment, then register your agent from wherever it runs.

Step 1: Jentic One Host machine

# On the machine that will host your Jentic One instance:
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh

Step 2: Agent machine

# On the machine where your agent runs (keep this separate from the instance):
curl -fsSL https://raw.githubusercontent.com/jentic/jentic-one/main/tools/install.sh | sh
jentic register       # connects your agent to your Jentic One instance

Jentic One is in public beta. The setup above keeps your agent separate from the instance, which is what you want before using real credentials: an agent running as the same OS user as Jentic One can read its stored keys directly. Just evaluating? A single local install is fine to start. See the secure deployment guide for the tiers.

Capabilities

What an agent can do with AWS Single Sign-On Admin API.

Create and manage permission sets with CreatePermissionSet, UpdatePermissionSet, DeletePermissionSet

Assign a permission set to a principal in an AWS account using CreateAccountAssignment

Attach AWS-managed or customer-managed IAM policies to a permission set

For Agents

Configure IAM Identity Center permission sets, account assignments, and policy attachments. Agents can create permission sets, assign access, and attach managed or inline policies.

Use for: I need to create a new permission set in IAM Identity Center, Assign a permission set to a group for a specific AWS account, Attach the AdministratorAccess managed policy to a permission set, Add a customer-managed IAM policy reference to a permission set

Not supported: Does not authenticate end users, manage user directories, or issue session credentials - use only for configuring IAM Identity Center permission sets and account assignments.

Use Cases

Patterns agents use AWS Single Sign-On Admin API for, with concrete tasks.

★ Standardised Workforce Access Across AWS Accounts

Identity teams define permission sets such as 'ReadOnly', 'BillingAdmin', and 'DeveloperPowerUser' once, then assign them to groups in the directory for each target account. CreateAccountAssignment binds (principalId, principalType=GROUP, accountId, permissionSetArn), and ProvisionPermissionSet pushes the resulting role into the target account.

CreatePermissionSet 'ReadOnly', AttachManagedPolicyToPermissionSet with arn:aws:iam::aws:policy/ReadOnlyAccess, then CreateAccountAssignment for principalType=GROUP, principalId=<group-id>, accountId=<acct>, and ProvisionPermissionSet to roll it out.

Customer-Managed Policy Attachment for Tightly Scoped Access

When AWS-managed policies are too broad, teams reference customer-managed policies stored in the target accounts via AttachCustomerManagedPolicyReferenceToPermissionSet. This keeps policy authoring local to the account while letting a central permission set bind it to many principals.

AttachCustomerManagedPolicyReferenceToPermissionSet with the policy name and path 'finance-readonly'/'/' on the existing 'FinanceReadOnly' permission set, then ProvisionPermissionSet.

Attribute-Based Access Control

ABAC enabled on the IAM Identity Center instance lets the same permission set evaluate differently per user attribute (such as cost centre or team). CreateInstanceAccessControlAttributeConfiguration registers the attribute mapping; permission sets then reference those attributes in policy conditions.

CreateInstanceAccessControlAttributeConfiguration with AccessControlAttributes mapping 'CostCenter' to the user attribute path '${path:enterprise.costCenter}', then DescribeInstanceAccessControlAttributeConfiguration to verify the mapping.

AI Agent Access Provisioning via Jentic

AI agents using Jentic can answer 'who has access to account X?' or 'grant Sarah read-only access to the billing account' by calling sso-admin through Jentic. The agent searches by intent, loads the operation schema, and executes with vault-stored credentials.

Search Jentic for 'create account assignment iam identity center', execute CreateAccountAssignment for the target permission set ARN, then poll DescribeAccountAssignmentCreationStatus until Status=SUCCEEDED.

Why Jentic?

Three things that make agents converge on Jentic-routed access.

Credential isolation

Your AWS access keys are stored once, encrypted, by your own Jentic One instance and used to sign each SSO Admin request with SigV4 at execution time. They never enter the agent's prompt, logs, or context.

Intent-based discovery

Agents search Jentic by intent such as 'create a permission set' or 'assign access to an AWS account', and Jentic returns the matching SSO Admin operation with its input schema so the agent calls the right endpoint without browsing the reference docs.

FAQs

Specific to using AWS Single Sign-On Admin API through Jentic.

Why is there no official OpenAPI spec for AWS Single Sign-On Admin?

AWS does not publish an OpenAPI specification. Jentic generates and maintains this spec so that AI agents and developers can call AWS Single Sign-On Admin via structured tooling. It is validated against the live API and kept up to date. Get started with Jentic One, the self-hosted execution layer.

What authentication does the AWS Single Sign-On Admin use?

sso-admin uses AWS Signature Version 4 with IAM credentials and permissions on the sso:* and identitystore:* actions. Through Jentic, the AWS access key and secret are stored encrypted in the vault - Jentic signs each call before forwarding it to the regional sso-admin endpoint.

Can I create a permission set with both managed and inline policies?

Yes. CreatePermissionSet creates the empty set, then AttachManagedPolicyToPermissionSet attaches one or more AWS-managed policies and PutInlinePolicyToPermissionSet adds a custom inline policy. Customer-managed policies are referenced through AttachCustomerManagedPolicyReferenceToPermissionSet.

What are the rate limits for the AWS Single Sign-On Admin?

sso-admin applies standard AWS API throttling - most operations are limited to a few requests per second per account per region with brief burst capacity, and account-assignment operations are async. Throttled calls return ThrottlingException; retry with exponential backoff.

How do I assign a permission set to a group through Jentic?

Through Jentic, search for 'create account assignment iam identity center', load the CreateAccountAssignment schema, and execute with InstanceArn, TargetId (account id), TargetType=AWS_ACCOUNT, PermissionSetArn, PrincipalType=GROUP, and PrincipalId. Then poll DescribeAccountAssignmentCreationStatus with the returned RequestId until Status=SUCCEEDED.

Is AWS Single Sign-On Admin free?

IAM Identity Center is offered at no additional charge - you pay only for the underlying AWS resources that the assigned roles access. SSO connections to external SaaS applications are also included.

Can I limit what my agent is allowed to do with the AWS SSO Admin API?

Yes. Because you run Jentic One yourself, your own rules decide which SSO Admin operations the agent may call, even though every action routes through one endpoint keyed by X-Amz-Target rather than by resource ids in the path. You can grant read-only work such as DescribePermissionSet and ListAccountAssignments while withholding CreateAccountAssignment, or allow assignment creation without exposing destructive operations like DeleteAccountAssignment or DeletePermissionSet. The agent can only invoke the operations you have added, and the AWS keys used to sign each request stay with your instance rather than the agent.
