## Tools

40 declared. Statically extracted from the shipped source — a floor on the surface, not a census.
- `archive_url` — Get a download URL for a .nyxmix archive of the session (project, lossless audio, transcripts, versions, and the custom plugins it uses) — for backups or moving
- `batch_process` — Run one destructive process (see process_audio kinds, e.g. loudness, denoise, voiceDenoise, declip) on several files — by default every file used on the timelin
- `stretch_clip` — Time-stretch one clip to an exact length (duration in seconds) or by a ratio, keeping its pitch (Rubber Band, high quality) — e.g. fit a music bed to 30.0 s. Cr
- `export_cd` — Export a CD image (Audition: CD Layout): 44.1 kHz/16-bit dithered WAV plus a CUE sheet. Every labelled marker starts a CD track (titles from labels, min 4 s apa
- `check_delivery`
- `convert_sample_rate` — Change the session sample rate (44100, 48000, 88200, 96000): every file is resampled with SoX (high quality); clip times and the arrangement stay the same. Not 
- `auto_duck` — Lower a music/bed track automatically wherever the voice tracks are speaking. Writes volume automation on the music track (replacing its existing volume automat
- `install_faust_plugin`
- `generate_audio`
- `list_lv2_plugins` — Search the native effect plugins installed on the server — LV2 and VST3 (LSP, x42, Calf, ZAM, Dragonfly, DISTRHO, MDA, …: EQs, compressors, limiters, gates, rev
- `lv2_plugin_info` — Controls of one LV2 or VST3 plugin (by uri or #index from list_lv2_plugins): symbol, label, range, unit, default, toggles and enumerations. Pass values by symbo
- `apply_lv2_plugin`
- `list_projects` — List editing sessions.
- `create_project` — Create an empty session.
- `get_project` — Read the session: tracks, clips (with times), effects, assets, markers. format "summary" (default) is compact text; "json" is the full document.
- `describe_capabilities` — Effect types with parameter ranges, destructive processes, and export formats.
- `import_audio` — Add an audio file to the session bin from a public URL or base64 data. Any common format; converted losslessly to 32-bit float at the project rate. Returns the 
- `edit`
- `undo` — Undo the last edit (by anyone).
- `redo` — Redo.
- `analyze` — Measure audio: EBU R128 loudness (integrated LUFS, LRA, true peak), sample peak/RMS/clipping/DC, silent stretches, spectral band balance, optional RMS envelope.
- `get_image` — Render a waveform or spectrogram PNG of the mix, an asset or a clip, so you can look at the audio.
- `process_audio`
- `render` — Export the mix. Returns a download URL plus measured loudness. bounce:true instead adds the mixdown to the bin as a new asset.
- `get_activity` — Recent edits with author (human or agent) — use it to see what the human changed.
- `pitch_curve` — Manual pitch correction: shift a voice by a curve of points {time (asset/source seconds), cents} — linear between points, 0 outside, so put 0-cent points around

## Install

**Verdict: review** — Installable, but 1 thing to check first: No publisher has proved control of this listing; it is indexed, not vouched for.
**Cautions** (coverage gaps and advisories — never blocking)
- No publisher has proved control of this listing; it is indexed, not vouched for.
**Config** (claude-code):
```json
"{\n  \"mcpServers\": {\n    \"nyxmix\": {\n      \"command\": \"npx\",\n      \"args\": [\n        \"-y\",\n        \"nyxmix\"\n      ],\n      \"env\": {\n        \"NYXMIX_TOKEN\": \"<YOUR_NYXMIX_TOKEN>\"\n      }\n    }\n  }\n}"
```
**Credentials it will ask for** (names only — Forge never holds a value):
- `NYXMIX_TOKEN` — Nyxmix Token (optional)
Placeholders only. Forge never holds, brokers, or transmits a credential value — replace each <YOUR_NAME> in your own config file. Do not send a value back to Forge; no Forge endpoint accepts one.
- This entry needs 1 credential (0 required). The generated config carries placeholders, so it will fail in the editor rather than at runtime if they are left unset.

## Blast radius

Extensive blast radius — deletes data; holds an api key.
- Floor 56, ceiling 56 (tier: extensive)
- This is impact, not likelihood. A high radius is not a defect: a filesystem server is supposed to write files. It is never part of the trust score.
