mypy-boto3-schemas

What it is and what it does

This package provides type stubs and annotations for the boto3 Schemas service, generated by mypy-boto3-builder 8.12.0. It enables static type checkers like mypy and pyright, plus IDE features like autocomplete and inline documentation in VSCode, PyCharm, Emacs, and Sublime Text, without requiring explicit type annotations in your code. The package is type-only—it adds no runtime behavior and depends only on typing-extensions.

It covers the full Schemas API surface: client methods, paginators, waiters, and type-safe literals for service parameters. The package is actively maintained, supports Python 3.9 through 3.14, and is part of the broader boto3-stubs ecosystem. Installation is straightforward (pip install mypy-boto3-schemas or as part of boto3-stubs[schemas]), and it integrates transparently with standard development workflows.

Use it for:

• Enable mypy or pyright type checking on boto3 Schemas code without manual type annotations.
• Get IDE autocomplete and inline documentation for Schemas API calls in VSCode with Pylance or PyCharm.
• Catch Schemas API usage errors at development time rather than runtime.
• Use TYPE_CHECKING guards to keep type stubs out of production dependencies while maintaining type safety.
• Support multi-IDE development teams (VSCode, PyCharm, Emacs, Sublime) with consistent type information.

Worth the install?

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

Provides type annotations and IDE autocomplete support for the boto3 Schemas service, enabling static type checking with mypy, pyright, and other tools.

Yes. Install this if you use boto3 Schemas and want static type checking or IDE autocomplete. It has no runtime cost, minimal dependencies, is actively maintained, carries an MIT license, and integrates seamlessly into existing boto3 workflows. The only caveat: PyCharm users should be aware of documented Literal overload performance issues and may prefer boto3-stubs-lite as an alternative.

pip install mypy-boto3-schemas

uv add mypy-boto3-schemas

poetry add mypy-boto3-schemas

Installing mypy-boto3-schemas

Before you install

Low friction: single runtime dependency (typing-extensions), pure Python wheel, actively maintained with recent releases. Designed as a type-only stub package with no runtime overhead.

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-schemas

from boto3.session import Session
from mypy_boto3_schemas import SchemasClient

client: SchemasClient = Session().client("schemas")

Requires boto3 1.43.0 to be installed separately; Python 3.9 or later.

Verify before relying

• Whether the package works correctly with boto3 versions other than 1.43.0 or if it requires exact version matching.
• Performance impact in PyCharm compared to boto3-stubs-lite, given the documented Literal overload performance issue.
