# mypy-boto3-ssm — Type annotations for boto3 SSM 1.43.53 service generated with mypy-boto3-builder 8.12.0

License: permissive · Maintenance: active · Downloads: 3.4M/mo

## 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.

## Worth the install?

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

Provides type stubs and annotations for boto3's SSM (Systems Manager) service, enabling IDE autocomplete, type checking, and static analysis across mypy, pyright, VSCode, PyCharm, and other tools.

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.

## Install

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

## Installing mypy-boto3-ssm

Before you install: 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.

License in practice: MIT license permits unrestricted use, modification, and distribution in both open-source and proprietary projects with minimal attribution requirements.

Quickstart:

# Install
python -m pip install mypy-boto3-ssm

# Use in code
from boto3.session import Session
from mypy_boto3_ssm import SSMClient

client: SSMClient = Session().client("ssm")
# Type checking and IDE autocomplete now work on client calls

Requires Python 3.9 or later; boto3 itself must be installed separately to use the client at runtime.

Verify before relying:

- Whether performance impact on PyCharm is acceptable for your codebase (documentation notes potential slowness with Literal overloads).
- Whether boto3-stubs-lite is a better fit if you need lighter memory footprint or encounter PyCharm performance issues.
