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.

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.

Install Jentic One Beta (Self-Hosted)

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

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.

Jentic publishes the only available OpenAPI specification for AWS Single Sign-On Admin, keeping it validated and agent-ready. The IAM Identity Center admin API configures who can access which AWS accounts with which roles. Agents can create and manage permission sets, attach AWS-managed and customer-managed IAM policies, define inline policies and permissions boundaries, assign permission sets to principals (users or groups) for specific AWS accounts, and provision those assignments across the organisation. The 37 operations cover permission sets, account assignments, instance access control attributes, inline policies, and managed policy attachments.

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 though Jentic?

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

Credential isolation

AWS access keys are stored encrypted in the Jentic vault. Each sso-admin call is signed with SigV4 server-side — the agent never holds the raw credential and policy ARNs flow through the call without leaving Jentic.

Intent-based discovery

Agents search by intent (for example, 'create permission set' or 'assign access to an aws account') and Jentic returns the matching sso-admin operations with input schemas, letting the agent invoke CreatePermissionSet or CreateAccountAssignment directly.

Time to first call

Direct sso-admin integration: 2-3 days for IAM, SigV4 signing, async assignment polling, and policy attachment ordering. Through Jentic: under 1 hour — search, load schema, execute.

Related APIs

Alternatives and complements available in the Jentic catalogue.

Complementary

AWS Single Sign-On

Runtime portal that consumes the assignments configured through sso-admin

Use sso-admin to configure access; users and tools then call the SSO Portal to fetch role credentials based on those assignments

Complementary

AWS SSO OIDC

OIDC device flow that issues bearer tokens for the SSO Portal

Pair sso-admin assignments with sso-oidc when building a CLI or tool that authenticates IAM Identity Center users

Alternative

AWS Security Token Service

AssumeRole-based federation for IAM principals when IAM Identity Center is not in scope

Pick STS AssumeRole when access is granted to classic IAM users or roles directly; use sso-admin when the workforce is managed in IAM Identity Center

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 at https://app.jentic.com/sign-up.

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.
