mypy-boto3-iot

What it is and what it does

mypy-boto3-iot is a type-stub package that adds complete type annotations for boto3's AWS IoT service. It enables static type checkers (mypy, pyright) and IDEs (VSCode, PyCharm, Emacs, Sublime Text) to provide accurate autocomplete, type hints, and error detection when working with IoT client methods, paginators, and service resources. The package is generated from boto3 1.43.20 and requires only typing-extensions as a runtime dependency.

The package is designed to be used alongside boto3 itself—it does not replace boto3, only augments it with type information. You can install it standalone or as part of boto3-stubs, a larger collection of service stubs. It supports Python 3.9 through 3.14 and is actively maintained, with the repository showing recent commits and stable production status.

Use it for:

• Enable mypy or pyright type checking on boto3 IoT code to catch type errors before runtime.
• Get IDE autocomplete and inline documentation for IoT client methods and parameters in VSCode or Sublime Text.
• Use in PyCharm with the lite variant to avoid performance degradation from Literal overload handling.
• Annotate function signatures that accept IoT clients or resources with precise types like IoTClient.
• Validate paginator usage with explicit type annotations for IoT list operations.

Worth the install?

AI-flagged interpretation of the facts on this page — verify before relying

Provides type annotations and IDE autocomplete support for boto3's AWS IoT service, enabling static type checking with mypy, pyright, and other tools.

Yes. Install if you use boto3 for AWS IoT and want static type checking or IDE autocomplete. Low install friction, no security issues, permissive license, and active maintenance make it a straightforward addition. PyCharm users should consider the lite variant if performance is a concern.

Install

mypy-boto3-iot on PyPI

pip install mypy-boto3-iot

uv add mypy-boto3-iot

poetry add mypy-boto3-iot

Installing mypy-boto3-iot

Before you install

Low friction: single runtime dependency (typing-extensions), wheel-only distribution, and actively maintained with a recent release 73 days ago.

License in practice

MIT license permits unrestricted use, modification, and distribution in both open-source and proprietary projects.

Quickstart

pip install mypy-boto3-iot

from boto3.session import Session
from mypy_boto3_iot import IoTClient

client: IoTClient = Session().client("iot")
# Type checking and IDE completion now work on client calls

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

Verify before relying

• Whether performance issues in PyCharm mentioned in the description (issue PY-40997) remain unresolved or have been addressed.
• Whether the lite variant (boto3-stubs-lite) offers materially better IDE performance for PyCharm users.
