# mypy-boto3-mturk — Type annotations for boto3 MTurk 1.43.0 service generated with mypy-boto3-builder 8.12.0

License: permissive · Maintenance: active · Downloads: 251.0K/mo

## What it is and what it does

This package is a type-stub library that adds type annotations to boto3's MTurk service client. It is generated from boto3 1.43.0 using mypy-boto3-builder 8.12.0 and works with VSCode, PyCharm, Emacs, Sublime Text, mypy, pyright, and other type-aware tools. When installed, it enables IDE autocomplete for MTurk API calls and allows static type checkers to catch errors before runtime.

The package is stub-only (no runtime code) and depends only on typing-extensions. It supports Python 3.9 through 3.14 and is designed to be used alongside boto3 itself. Type annotations cover the MTurk client, paginators, type definitions, and literal values for service parameters. The documentation recommends using boto3-stubs-lite for PyCharm if performance is a concern due to Literal overload handling.

Use it for:

- Enable IDE autocomplete and parameter hints when writing boto3 MTurk client code in VSCode or PyCharm.
- Catch MTurk API usage errors at type-check time with mypy or pyright before deployment.
- Document expected parameter types and return types for MTurk operations in your codebase.
- Use TYPE_CHECKING guards to keep type annotations dev-only while avoiding runtime dependencies.
- Paginator type annotations for MTurk list operations like ListHITs and ListAssignmentsForHIT.

## Worth the install?

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

Provides type annotations for boto3's MTurk service, enabling IDE autocomplete and static type checking with mypy, pyright, and other tools.

Yes. Install if you use boto3 MTurk and want static type checking or IDE autocomplete. The package is actively maintained, has no security vulnerabilities, carries a permissive MIT license, and installs with minimal friction. The only caveat is PyCharm performance with Literal overloads—use boto3-stubs-lite as an alternative if that becomes a problem.

## Install

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

## Installing mypy-boto3-mturk

Before you install: Low friction—a single wheel dependency on typing-extensions. Actively maintained as of 2026-06-22 with 670 repository stars.

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

Quickstart:

pip install mypy-boto3-mturk

from boto3.session import Session
from mypy_boto3_mturk import MTurkClient

client: MTurkClient = Session().client("mturk")

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

Verify before relying:

- Whether performance issues with PyCharm Literal overloads (PY-40997) have been resolved in recent PyCharm versions.
- Whether the package works correctly with boto3 versions other than 1.43.0.
