mypy-boto3-proton

What it is and what it does

This package is a type-stub library that adds complete type annotations for AWS Proton operations in boto3. It is generated automatically from boto3 1.43.0 and works with mypy, pyright, VSCode Pylance, PyCharm, Emacs, Sublime Text, and other IDE and type-checker tooling. When installed, it enables static type checking and IDE autocompletion for Proton client calls, paginators, and waiters without requiring explicit type annotations in your code.

The package is a pure Python stub-only distribution with minimal dependencies (only typing-extensions). It is designed to be installed in development environments and can be safely excluded from production deployments using TYPE_CHECKING guards. The package is actively maintained, tracking boto3 releases, and has been in production use since 2021.

Use it for:

• Enable IDE autocompletion and type hints when writing boto3 Proton code in VSCode or PyCharm
• Catch type errors in AWS Proton API calls during development with mypy or pyright before runtime
• Document expected parameter types and return values for Proton client methods in your codebase
• Use with boto3-stubs[proton] for full type support across all Proton operations and paginators
• Integrate type checking into CI/CD pipelines to validate AWS SDK usage correctness

Worth the install?

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

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

Yes. Install this if you use boto3 with AWS Proton and want static type checking or IDE autocompletion. It has low friction (one lightweight dependency), is actively maintained, carries no security vulnerabilities, and uses a permissive MIT license. The only caveat is PyCharm users may experience performance issues with Literal overloads; the docs recommend boto3-stubs-lite as a workaround in that case.

Install

mypy-boto3-proton on PyPI

pip install mypy-boto3-proton

uv add mypy-boto3-proton

poetry add mypy-boto3-proton

Installing mypy-boto3-proton

Before you install

Low friction: single lightweight dependency (typing-extensions), pure Python wheel, actively maintained with recent releases. Generated automatically from boto3 1.43.0, so updates track upstream AWS SDK changes.

License in practice

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

Quickstart

pip install mypy-boto3-proton

from boto3.session import Session
from mypy_boto3_proton import ProtonClient

client: ProtonClient = Session().client("proton")
# Type checking and IDE completion now work automatically

Requires Python 3.9 or later; intended as a development/type-checking dependency, not runtime.

Verify before relying

• Whether PyCharm performance issues mentioned in docs (issue PY-40997) remain unresolved or have been addressed
• Exact coverage of Proton service operations and whether all boto3 1.43.0 Proton APIs are annotated
