audial-mcp
Run Audial's hosted audio tools from any MCP client: split stems, analyze and segment audio, master tracks, build sample packs, convert audio to MIDI, generate music, turn a one-shot into an editable Audial Synth preset, and sing lyrics in a reference voice.
mcp-name: io.github.AudialAI/audial-mcp

Tools
| Tool | What it does |
|---|---|
stem_split | Split a track into vocals, drums, bass, other (optionally retime / rekey) |
analyze | BPM, key and other characteristics |
segment | Sections and component analysis |
master | Mastering, optionally matched to a reference |
generate_samples | Sample pack from a track |
generate_midi | Audio to MIDI |
generate_music | Text to music, covers, remixes, extraction, completion with the Audial music model |
sound2vital | One-shot → editable Audial Synth (Vital) preset |
text2vox | Lyrics + reference voice → sung vocal and MIDI |
list_results | Browse previous results in your results folder |
What leaves your machine
Audio and text you pass to a tool are uploaded to Audial's API (https://api.audialmusic.ai)
over HTTPS and processed on Audial's servers; results are downloaded into
AUDIAL_RESULTS_DIR (default ~/Audial). Nothing else is sent.
Two other files are read if they exist, because the Audial SDK looks for them:
~/.audial/.audial_config.json and a .env in the directory the server was started from.
Credentials from your MCP client's config always win: audial-mcp snapshots its environment
before the SDK loads either file, so neither can redirect your credentials or the API host.
Every tool except list_results calls the Audial API, which requires an active Audial subscription on the account; without one the tool returns the API's subscription message.
Configuration
| Variable | Required | Default |

AUDIAL_API_KEY | yes | |
