Cloud MCP server
Your AI agent is now the sound designer.
Ask Claude Code or Cursor for a jump, a coin pickup or a level-up fanfare. make-sfx designs it from 70+ synth parameters, matches the loudness to its game category and hands back the WAV.
Less than a dollar a month. Works with any MCP client.

Unedited renders. The numbered buttons are seed variants of the same design, so repeated sounds never get stale.

The music gallery
Twenty-seven pieces, twenty-seven styles
A music-box waltz in 3/4, acid techno, a hijaz desert theme, a horror bed, a two-second game over. Each one is its own make-sfx project, rendered by the same engine your agent calls.

Ask for sounds
Describe what you need in plain words. The agent picks the parameters and gets the WAVs back.
claude mcp add --transport http make-sfx https://makesfx.tuntii.com/mcp \
--header "Authorization: Bearer YOUR_LICENSE_KEY"What your agent gets
Built for game audio, not generic noise
Natural language in
"Short, bright, a bit of reverb" turns into a full design. Refine it with words until it fits.
70+ parameters
4 oscillators, 4 LFOs, envelopes, texture and post-FX, for when the agent needs exact control.
Loudness that matches
UI, combat, pickup, ambient and stinger categories each hit their own LUFS target, so the mix holds.
Packs and variants
A whole starter pack in one call, with seed variants for every sound you hear more than once.
Music projects
Instruments, patterns, mixer and mastering in one project file the agent can write and edit.
Deterministic
The same design always renders the same bytes. Keep the design and you can rebuild the sound anytime.

Questions
Which AI tools does it work with?
Any MCP client that can connect to a remote server over HTTP and send a header: Claude Code, Cursor, Windsurf, VS Code and others. Browser chat apps that only accept sign-in connectors aren't supported yet.
What happens when the year is up?
Your plan renews yearly, and you can cancel anytime. If it lapses, the key stops working; every sound you made is already in your project and stays yours to use. A daily fair-use limit keeps the server fast for everyone.
Where do the files go?
The WAVs come back inside the tool response, and your agent saves them into your project. The server doesn't keep your sounds or projects.
Do I need to know synthesis?
No. Describe the sound. The parameters are there when you or your agent want precise control.
