What is Audio Plugin Soko-kun?

What this service is

Audio Plugin Soko-kun is an independent, open registry of open-source audio plugins. It is an unofficial service that is not affiliated with the developers of plugin formats or DAWs.

Supported formats: VST® 3 CLAP, LV2, Audio Unit

The registry does not host files. It records information from public GitHub repositories and links to the zip archives that authors publish in GitHub Releases.

Download files directly from GitHub, because this platform does not host them.

Use from AI agents (MCP)

Connect an MCP client to the endpoint /mcp on this site. In Claude Code, run:

claude mcp add --transport http audio-plugin-soko-kun https://audio-soko-kun.allegromoltov.jp/mcp

In Codex, run:

codex mcp add audio-plugin-soko-kun --url https://audio-soko-kun.allegromoltov.jp/mcp

Searching and viewing details work without signing in to GitHub. To submit a repository, sign in with GitHub from the MCP client (in Claude Code, run /mcp; in Codex, run codex mcp login audio-plugin-soko-kun). This platform itself never gets write access to your GitHub repositories.

Example requests: "Find a pitch shift plugin that works on Windows", "Find a CLAP reverb for Apple Silicon Macs", "Register the audio plugin in this GitHub repository", "Check whether my plugin's new release is listed".

Supporting development

Audio Plugin Soko-kun is free to use. If you would like to help with its running costs and development, you can sponsor the developer on GitHub Sponsors: https://github.com/sponsors/AllegroMoltoV

Sponsoring is optional. It has no effect on how plugins are listed or checked.
