MCP server for batch audio processing and optimization using FFmpeg with parameter-based interface for sample rate conversion, bitrate adjustment
MCP Audio Tweaker becomes available to MCP clients through the mcp audio tweaker mcp server. MCP server for batch audio processing and optimization using FFmpeg with parameter-based interface for sample rate conversion, bitrate adjustment, and audio effects.
A Model Context Protocol (MCP) server for batch audio processing and optimization using FFmpeg. This package provides parameter-based audio modifications including sample rate conversion, bitrate adjustment, volume control, channel configuration, and audio effects.
Once connected, the assistant can call these 7 tools directly:
Prerequisites — The Prerequisites tool exposed by this serverprocess_audio_file — The process_audio_file tool exposed by this serverbatch_process_audio — The batch_process_audio tool exposed by this serverapply_preset — The apply_preset tool exposed by this serverlist_presets — The list_presets tool exposed by this serverget_queue_status — The get_queue_status tool exposed by this serverContributing — 1. Fork the repository 2. Create a feature branch 3. Make your changes 4. Add tests for new functionality 5. Submit a pull requestThe server is distributed via npm as mcp-audio-tweaker, so most clients can run it without a manual build step. Add it to your MCP client's configuration and restart the client to pick it up — the copy-paste configs for Claude Desktop, Claude Code and Cursor are on this page.
The server reads 2 environment variables: AUDIO_TWEAKER_LOG_LEVEL, FFMPEG_PATH. Keep credentials in your client's env block or a secrets manager rather than committing them.
Developer-tool servers are usually the first ones people connect, because they turn "help me with this code" into an assistant that can actually read the repo and act on it. MCP Audio Tweaker sits in that group, and the shape of its toolset — Prerequisites, process_audio_file, batch_process_audio among others — tells you what it is really for. Worth comparing against the other developer tools servers in this directory before you commit to one, since several overlap in scope but differ sharply in setup cost and permissions.
