# mypy-boto3-sso — Type annotations for boto3 SSO 1.43.0 service generated with mypy-boto3-builder 8.12.0

License: permissive · Maintenance: active · Downloads: 461.7K/mo

## What it is and what it does

mypy-boto3-sso is a type-stub package that adds complete type annotations to boto3's AWS SSO (Single Sign-On) service. It is generated from boto3 1.43.0 using mypy-boto3-builder 8.12.0 and works with type checkers like mypy and pyright, as well as IDEs including VSCode, PyCharm, Emacs, and Sublime Text.

When installed, it enables IDE autocomplete, catches type errors during development, and provides explicit type hints for SSOClient, paginators, and service-specific literals and type definitions. The package is a stub-only distribution (no runtime code) with a single runtime dependency on typing-extensions. It supports Python 3.9 through 3.14.

Use it for:

- Enable IDE autocomplete and type checking for boto3 SSO operations in VSCode with Pylance or PyCharm.
- Run mypy or pyright type checking on code that uses boto3 SSO without runtime errors.
- Explicitly annotate SSOClient types in functions to catch AWS API misuse at development time.
- Generate paginator type hints for list_account_roles and list_accounts operations.
- Use boto3 SSO in a TYPE_CHECKING block to avoid production dependencies while maintaining type safety.

## Worth the install?

AI-flagged interpretation of the facts above — verify before relying.

Provides type annotations for boto3's SSO service, enabling type checking and IDE autocomplete for AWS Single Sign-On operations.

Yes. If you use boto3's SSO service and want type checking or IDE support, this package is a straightforward, low-friction install with no security issues, active maintenance, and a permissive license. Install it alongside boto3 in your development environment or as part of boto3-stubs[sso] for a complete typed AWS SDK experience.

## Install

pip install mypy-boto3-sso
uv add mypy-boto3-sso
poetry add mypy-boto3-sso

## Installing mypy-boto3-sso

Before you install: Low friction install with a single runtime dependency (typing-extensions). The package is actively maintained with recent releases; repo shows 670 stars and last commit on 2026-06-22.

License in practice: MIT license permits unrestricted use, modification, and distribution with minimal restrictions—suitable for both open-source and commercial projects.

Quickstart:

pip install mypy-boto3-sso

from boto3.session import Session
from mypy_boto3_sso import SSOClient

client: SSOClient = Session().client("sso")

Requires Python 3.9 or later; boto3 must be installed separately in your environment.

Verify before relying:

- Whether PyCharm performance issues mentioned in the description (issue PY-40997) still affect current versions.
- Exact scope of type coverage for all SSO operations and edge cases.
