Instead of relying on the protobuf compiler's built-in pyi generator, it produces stubs with more precise type information\u2014including correctly typed HasField, WhichOneof, and ClearField methods; gRPC service and client stubs; and field presence awareness. It also preserves comments from .proto files as docstrings and marks deprecated items with @warnings.deprecated.\n\nThe plugin installs as a protoc-gen-mypy executable that integrates into the protoc build pipeline. You run it alongside the standard Python code generator, and it outputs .pyi files that type checkers like mypy and pyright can use to validate code that imports and uses the generated protobuf messages. It requires protoc >= 32.0, python-protobuf >= 6.32, and Python >= 3.9 to run; downstream type checking also needs mypy >= v1.14.0 or pyright >= 1.1.383.","worth_installing":"Yes. The package is actively maintained, has no known vulnerabilities, low install friction, and solves a real problem\u2014enabling static type checking on protobuf code where the built-in pyi generator falls short. Install it if you use protobuf in Python and want mypy or pyright to catch type errors in your message handling and gRPC calls. Verify that your protoc and protobuf versions match the required minimums (>= 32.0) before installing."},"id":"mypy-protobuf","links":{"html":"https://skillfed.io/packages/mypy-protobuf","md":"https://skillfed.io/packages/mypy-protobuf.md","pypi":"https://pypi.org/project/mypy-protobuf/"},"maintenance":{"status":"active"},"meta":{"latest_release":"2026-04-28","license_spdx":null,"license_treatment":"permissive","name":"mypy-protobuf","python_support":"supports_current","summary":"Generate mypy stub files from protobuf specs"},"popularity":{"monthly_downloads":9374790,"position":1539,"tier":"top_5000"},"security":{"n_vulnerabilities":0},"version":"5.1.0"}
