Type annotations for boto3 SSM 1.43.53 service generated with mypy-boto3-builder 8.12.0
Decision gist · record as of 2026-08-14
Yes, if you use boto3 SSM and want IDE support and type checking. Install friction is minimal (one pure-Python dependency), maintenance is active, and the package is widely used (top 5000 on PyPI). The only caveat: PyCharm users may experience performance issues and should consider boto3-stubs-lite instead. No security vulnerabilities are known.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.9 or later; boto3 itself must be installed separately to use the client at runtime.
- Low friction: single pure-Python wheel dependency on typing-extensions.
- Active maintenance with recent release (24 days old); repository shows 670 stars and current activity.

What it is and what it does
mypy-boto3-ssm is a type stub package that adds complete type annotations for the boto3 SSM service. It is generated from boto3 1.43.53 and works as a companion to boto3, providing type information that IDEs and static type checkers can use to offer autocomplete, catch type errors, and validate your code without requiring explicit type hints in your own code.
The package is designed to work with multiple tools: VSCode with Pylance, PyCharm, Emacs with lsp-pyright, Sublime Text, mypy, and pyright. You install it alongside boto3, and type information becomes available immediately—no code changes needed. It includes annotations for the SSM client, paginators, waiters, and type definitions, though the documentation notes that PyCharm may experience performance issues with the full Literal overloads, in which case the lighter boto3-stubs-lite variant is recommended.
Use it for
- Enable IDE autocomplete and parameter hints when writing boto3 SSM code in VSCode or PyCharm without manual type annotations.
- Catch type errors in boto3 SSM calls during development using mypy or pyright before runtime.
- Document SSM client method signatures and return types for team members reading your code.
- Validate boto3 SSM paginator and waiter usage with full type information in static analysis pipelines.
- Use boto3 SSM in a TYPE_CHECKING block to get type hints without adding a production dependency.
