Show HN: AwsmAudio – a WebAudio editor with native MCP

AwsmAudio, a WebAudio editor with native MCP support, was released on GitHub. The tool allows both humans and AI agents to create and control synthesized sounds programmatically, targeting creative coders for use in games and simulations. It exposes WebAudio primitives through a UI and MCP server, with an AudioWorklet that accepts WASM files for digital signal processing.

Hey y'all, So - the main idea of this is to make a WebAudio synthesis/sequencer tool which humans can use via the UI, but where the big unlock is for agents to drive with MCP It's semi decent as "make a groovy jazz track", especially for retro sounds - but the real use case is more like "make a jetpack whoosh effect I can control via code at runtime - where the sound changes based on character health or how much fuel is left" In other words, the target audience is not musicians except maybe of the Max/MSP sort , but more like creative coders who want to shape the sound iteratively with an agent, and then use and drive in in a game/simulation. Fwiw I think this approach is going to be more and more... and I'm working on a renderer/editor tool too will share separately when ready . What I mean is, there's a lot of "block box" AI tooling out there, and a lot of "add MCP to existing tools", but building new tools where humans get one experience and MCP exposes another layer really just for agents.. I think that's powerful. Most if it is just mapping the WebAudio primitives to a UI and MCP server - but the AudioWorklet is a bit more interesting in that it expects a WASM file of a particular shape, and then uses that to expose the parameters in the UI and hook in as a Digital Signal Processor. That's the kind of thing that is nice for humans, but too convoluted to be usable in a UI, and agents can use super easily. As of right now, there's no hosting - so the MCP server is local as is project save/loading.
