# mypy-boto3-discovery — Type annotations for boto3 ApplicationDiscoveryService 1.43.0 service generated with mypy-boto3-builder 8.12.0

License: permissive · Maintenance: active · Downloads: 251.3K/mo

## What it is and what it does

mypy-boto3-discovery is a stub package that adds complete type annotations for AWS boto3's ApplicationDiscoveryService. It's generated from boto3 1.43.0 and works with mypy, pyright, VSCode, PyCharm, Emacs, Sublime Text, and other type-aware tools. The package enables IDE autocomplete and static type checking without requiring explicit type hints in your code—you write boto3 code normally, and the stubs provide the type information behind the scenes.

The package is designed as a lightweight addition to boto3 with minimal dependencies (only typing-extensions). It supports Python 3.9 through 3.14 and is marked as Production/Stable. The stubs include annotations for the client, paginators, waiters, and type definitions specific to the ApplicationDiscoveryService, allowing your type checker to catch errors before runtime.

Use it for:

- Enable IDE autocomplete and inline documentation for ApplicationDiscoveryService client methods in VSCode or PyCharm.
- Run mypy or pyright type checking on boto3 code to catch type mismatches before deployment.
- Provide explicit type hints in a codebase that uses boto3 ApplicationDiscoveryService without writing manual annotations.
- Support LSP-based editors (Emacs, Sublime Text) with type information for boto3 discovery operations.
- Reduce runtime errors by catching incorrect boto3 API calls during static analysis.

## Worth the install?

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

Provides type annotations and IDE autocomplete support for boto3's ApplicationDiscoveryService, enabling static type checking with mypy, pyright, and compatible editors.

Yes. This is a low-friction, actively maintained stub package with no security issues, permissive licensing, and broad IDE support. Install it if you use boto3's ApplicationDiscoveryService and want type checking or IDE autocomplete; it adds no runtime overhead and integrates transparently with standard Python tooling.

## Install

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

## Installing mypy-boto3-discovery

Before you install: Low friction install with a single lightweight dependency (typing-extensions). Actively maintained with recent updates; repository shows steady activity and community adoption.

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

Quickstart:

pip install mypy-boto3-discovery

from boto3.session import Session
from mypy_boto3_discovery import ApplicationDiscoveryServiceClient

client: ApplicationDiscoveryServiceClient = Session().client("discovery")

Requires Python 3.9 or later; boto3 must be installed separately in your environment.

Verify before relying:

- Whether the package works with boto3 versions other than 1.43.0 or if it requires exact version matching.
- Performance impact on IDEs other than VSCode and PyCharm when using full boto3-stubs versus the lite variant.
