mypy-boto3-kms
Type annotations for boto3 KMS 1.43.12 service generated with mypy-boto3-builder 8.12.0
Decision gist · record as of 2026-08-14
Yes, if you use boto3 KMS in a typed Python project. Install friction is minimal, maintenance is active, and the MIT license poses no restrictions. The only caveat is PyCharm performance with full type coverage—use boto3-stubs-lite instead if you encounter slowdowns. For mypy, pyright, VSCode, or other type-aware tools, this package is a straightforward win.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.9 or later; boto3 must be installed separately in your environment.
- Low install friction; single runtime dependency on typing-extensions.
- Actively maintained with recent releases; repository has 670 stars and last commit on 2026-06-22.

What it is and what it does
This package is a type-stub library that adds static type information to boto3's KMS (Key Management Service) client. It is generated automatically from boto3 1.43.12 and works with mypy, pyright, VSCode Pylance, PyCharm, Emacs, Sublime Text, and other IDEs that support Python type hints. When installed, it enables IDE autocompletion, type checking, and inline documentation for all KMS API calls without requiring explicit type annotations in your code.
The package is designed as a development dependency—you can safely exclude it from production using TYPE_CHECKING guards. It provides annotations for the KMS client, paginators, waiters, and service resource types. The documentation notes that PyCharm may experience performance issues with the full type coverage due to extensive Literal overloads, in which case the lighter boto3-stubs-lite variant is recommended as an alternative.
Use it for
- Enable IDE autocompletion and type checking when writing boto3 KMS code in VSCode with Pylance or PyCharm.
- Catch KMS API usage errors at development time with mypy or pyright before running code.
- Document KMS client method signatures and return types inline in your editor without manual annotation.
- Use paginators and waiters with full type safety for KMS operations like listing keys or describing key stores.
- Integrate type checking into CI/CD pipelines to validate boto3 KMS calls across your codebase.
