# mypy-boto3-bedrock — Type annotations for boto3 Bedrock 1.43.26 service generated with mypy-boto3-builder 8.12.0

License: permissive · Maintenance: active · Downloads: 873.3K/mo

## What it is and what it does

This package is a type-stub library that adds static type information to boto3's Bedrock service client. It is generated automatically from boto3's API definitions and enables IDEs and type checkers to understand the shape and behavior of Bedrock API calls, providing code completion, parameter validation, and error detection at development time.

The package works with mypy, pyright, VSCode (via Pylance), PyCharm, Emacs, Sublime Text, and other tools that support Python type hints. It has no runtime behavior—it only provides type metadata. Installation is straightforward and adds minimal overhead; the single runtime dependency is typing-extensions. The package is actively maintained and supports Python 3.9 through 3.14.

Use it for:

- Enable IDE autocompletion and inline documentation when writing boto3 Bedrock client code.
- Catch type errors in Bedrock API calls before runtime using mypy or pyright in CI/CD pipelines.
- Reduce bugs by catching incorrect parameter names or types when invoking Bedrock operations.
- Improve code readability by making Bedrock client types explicit in function signatures and variable annotations.
- Use in VSCode with Pylance for seamless type checking without explicit annotations in boto3 code.

## Worth the install?

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

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

Yes—if you use boto3 with Bedrock and want static type checking or IDE autocompletion. Install friction is negligible, maintenance is active, the license is permissive, and there are no known vulnerabilities. The only gotcha is PyCharm performance on Literal overloads (documented in the description), which can be mitigated by using the lite variant or a different type checker.

## Install

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

## Installing mypy-boto3-bedrock

Before you install: Low friction—a single runtime dependency (typing-extensions) and a pure-Python wheel. Actively maintained with recent releases; the repository shows consistent activity and the package is in production-stable status.

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

Quickstart:

# Install
python -m pip install mypy-boto3-bedrock

# Use in code
from boto3.session import Session
from mypy_boto3_bedrock import BedrockClient

client: BedrockClient = Session().client("bedrock")

Requires Python 3.9 or later; boto3 itself must be installed separately to use the client at runtime.

Verify before relying:

- Whether the package works with all boto3 versions or only 1.43.26 specifically.
- Performance impact in PyCharm compared to the lite variant mentioned in the description.
