mypy-boto3-m2
Type annotations for boto3 MainframeModernization 1.43.0 service generated with mypy-boto3-builder 8.12.0
Decision gist · record as of 2026-08-14
Yes, if you use boto3's MainframeModernization service and want type safety. Installation is frictionless, maintenance is active, the license is permissive, and there are no known vulnerabilities. The only caveat is PyCharm users may experience performance issues with the full stubs (the docs recommend boto3-stubs-lite as a workaround), but VSCode, mypy, and pyright users should see immediate value.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 as a runtime dependency.
- Low friction installation as a pure-Python wheel with minimal dependencies.
- Actively maintained with recent commits; part of the established mypy-boto3-builder ecosystem.

What it is and what it does
This package is a type-stub library that adds static type information to boto3's MainframeModernization (m2) service. It generates precise type hints for the service client, paginators, and type definitions, enabling IDEs and type checkers to catch errors at development time rather than runtime. The stubs are generated from boto3 1.43.0 using mypy-boto3-builder 8.12.0 and work with VSCode, PyCharm, Emacs, Sublime Text, mypy, pyright, and other tools that support Python type hints.
You install it alongside boto3 and then use boto3 normally—the type annotations are picked up automatically by your IDE or type checker, providing autocomplete suggestions and flagging type mismatches. It has only one runtime dependency (typing-extensions) and is designed to be lightweight. The package supports Python 3.9 through 3.14 and is marked as Production/Stable.
Use it for
- Add IDE autocomplete and type checking to boto3 MainframeModernization code without writing manual type annotations.
- Catch type errors in AWS SDK calls during development using mypy or pyright before deployment.
- Enable PyCharm or VSCode to suggest correct method signatures and parameter types for m2 service operations.
- Document boto3 MainframeModernization API contracts in your codebase through inferred types.
- Use boto3 code with TYPE_CHECKING guards to keep type stubs out of production dependencies.
