Typing stubs for contextvars
Decision gist · record as of 2026-08-14
Yes, if you use contextvars and need type checking with mypy, pyright, or pytype on Python versions up to those tested. However, be aware that the package is unmaintained—if you are on a newer Python version or type-checker version than those listed, the stubs may become inaccurate. For modern Python (3.7+), consider whether your type checker already includes contextvars stubs inline before installing.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- This package is only useful when running a static type checker (mypy, pyright, pytype, or IDE type checking); it provides no runtime functionality.
- Low friction installation as a pure-Python stub package with no runtime dependencies.
- However, the package is explicitly unmaintained and has not been updated since July 2023, so it will not receive fixes for new Python versions or type-checking tool changes.

Verify before relying
pip install types-contextvars
# Then use in your code with type checking enabled:
import contextvars
my_var: contextvars.ContextVar[str] = contextvars.ContextVar('my_var')- Whether the stubs remain accurate for contextvars in current Python versions beyond those tested (mypy 1.4.1, pyright 1.1.316, pytype 2023.6.16)
- Whether unmaintained status will cause compatibility issues as type checkers evolve
What it is and what it does
types-contextvars is a PEP 561 type stub package that supplies type annotations for Python's built-in contextvars module. It allows static type checkers and IDEs to understand the types and signatures of contextvars functions and classes, enabling developers to catch type errors during development rather than at runtime.
The package is generated from typeshed and was last tested with mypy 1.4.1, pyright 1.1.316, and pytype 2023.6.16. It has no runtime dependencies and installs as a pure-Python wheel. However, the package is explicitly unmaintained and will not receive updates, so its accuracy may drift as Python and type-checking tools evolve.
Use it for
- Enable mypy or pyright to type-check code that uses contextvars.ContextVar for thread-safe context storage
- Provide IDE autocomplete and type hints when working with context variables in modern Python projects
- Validate type safety in async frameworks that rely on contextvars for managing request-scoped state
- Support legacy projects still using older type-checking tool versions that require explicit stubs
