# types-boto3-kms — Type annotations for boto3 KMS 1.43.12 service generated with mypy-boto3-builder 8.12.0

License: permissive · Maintenance: active · Downloads: 592.0K/mo

## What it is and what it does

types-boto3-kms is a type-stub package that adds static type information to boto3's KMS service client. It is generated from boto3 1.43.12 using mypy-boto3-builder 8.12.0 and works with VSCode, PyCharm, Emacs, Sublime Text, mypy, pyright, and other type-aware tools. When installed, it enables IDE autocompletion and type checking on KMS client methods without requiring explicit type annotations in your code.

The package is designed as a development dependency—you can use TYPE_CHECKING guards to avoid including it in production builds. It supports Python 3.9 through 3.14 and has a single runtime dependency on typing-extensions. The generated stubs cover KMS client operations, paginators, waiters, and type definitions, allowing your IDE and type checker to catch potential bugs before runtime.

Use it for:

- Enable IDE autocompletion and type hints when writing boto3 KMS client code in VSCode or PyCharm.
- Run mypy or pyright type checking on KMS operations to catch incorrect argument types or missing required parameters.
- Use in a development environment to catch AWS API misuse early without runtime errors.
- Provide type information for KMS paginator and waiter operations in type-aware editors.
- Guard type imports with TYPE_CHECKING to keep type stubs out of production dependencies.

## Worth the install?

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

Provides type annotations and IDE autocompletion support for boto3 KMS 1.43.12, enabling static type checking with mypy, pyright, and other tools.

Yes, if you use boto3 KMS and want IDE autocompletion or static type checking. Install friction is minimal, maintenance is active, and the MIT license poses no restrictions. The package is a pure type-stub with no runtime overhead when guarded by TYPE_CHECKING. Skip it only if you do not use type checking or IDE type hints in your workflow.

## Install

pip install types-boto3-kms
uv add types-boto3-kms
poetry add types-boto3-kms

## Installing types-boto3-kms

Before you install: Low friction install with a single runtime dependency (typing-extensions). Actively maintained as of 2026-06-22 with stable production status.

License in practice: MIT license permits unrestricted use, modification, and distribution in both open-source and commercial projects.

Quickstart:

pip install types-boto3-kms

from boto3.session import Session
from types_boto3_kms import KMSClient

client: KMSClient = Session().client("kms")
# Type checking and IDE completion now work on client methods

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

Verify before relying:

- Performance impact on PyCharm type checking with Literal overloads (documentation mentions issue PY-40997 but does not confirm current status).
- Whether types-boto3-lite variant is recommended over this package for specific IDE or performance scenarios.
