loudcheck

Overview

loudcheck is an MCP server that validates audio loudness compliance against EBU R128 and ATSC A/85 standards, delivering pass or fail verdicts along with exact ffmpeg remediation commands. It integrates directly into AI assistants as an invokable tool, enabling automated loudness analysis and correction workflows.

The server runs locally via uvx loudcheck with no authentication required. It operates over stdio as a Python package, making it ready to use immediately on your machine. Version v0.3.1 is published under the MIT license with source code available at chaoz23/loudcheck on GitHub.

loudcheck appears in the Security category on mcp.site and works with Claude Desktop, Claude Code, Cursor, VS Code, Windsurf, Zed, and other MCP clients. If you maintain this project, claim your listing to verify ownership and keep information current.
