This MCP server formats a single .proto file, making it easy to integrate into your toolchain or editor workflows. It provides a focused, reliable way to ensure your proto definitions are consistently formatted as part of your development process.

How to use

You can use this MCP server with any MCP client to format a .proto file. Send the file to the server, and it will return a reformatted version that adheres to standard proto syntax conventions. This is handy when integrating formatting into your editor, CI, or pre-commit checks to keep your proto definitions clean and consistent.

How to install

Prerequisites include having Go installed on your system so you can install the MCP server binary.

go install github.com/emicklei/protofmt-mcp@latest

Additional notes

Usage in development environments often involves configuring your MCP client to invoke the local MCP server binary. The server is designed to run as a local process that you can connect to via the MCP protocol to format a provided .proto file.
