# Lint protobuf definitions for style and correctness before code generation and review churn begin with protolint

Catch naming, formatting, and protobuf rule violations early so generated clients and reviews are cleaner.

## Prerequisites

protolint installation, protobuf source files, and optional CI or pre-commit integration where lint findings should gate changes

## Installation

Use the upstream install or setup path that matches your environment:
- brew tap yoheimuta/protolint
- brew install protolint
- Since [homebrew-core](https://github.com/Homebrew/homebrew-core/pkgs/container/core%2Fprotolint) includes protolint, you can also install it by just brew install protolint. This is the default tap that is installed by...
- go install github.com/yoheimuta/protolint/cmd/protolint@latest

Requirements and caveats from upstream:
- [![Docker](https://img.shields.io/docker/pulls/yoheimuta/protolint)](https://hub.docker.com/r/yoheimuta/protolint)
- ### Use the maintained Docker image
- protolint ships a Docker image [yoheimuta/protolint](https://hub.docker.com/r/yoheimuta/protolint) that allows you to use protolint as part of your Docker workflow.

Basic usage or getting-started notes:
- sh
- protolint --mcp
- For detailed documentation on how to use and integrate protolint's MCP server functionality, see the [MCP documentation](./mcp/README.md).
