First indexed and scored.

## MCP tools (5)

### `find_audio_files` (~90 tokens)

Find audio files on this machine by (partial) name — searches Downloads, Desktop, Music and Documents. Use this to resolve a file path when the user mentions a track by name (e.g. after dragging a file into chat, which does not reveal its local path). Free.

Input parameters:

- `query` (string, required): Part of the file name, case-insensitive (e.g. 'sunset drive')

### `analyze_track` (~195 tokens)

Analyze a LOCAL audio file (mp3/wav/flac/aiff/m4a/ogg, up to 15 MB) with TrackTag AI. Returns BPM, key, genres, moods, instruments, energy and 35+ metadata fields. Costs 1 TrackTag credit (model 'core') or 2 ('ultra') from the user's balance; failed analyses are auto-refunded. Needs the file's real path on this machine — if you only know the track's name (e.g. the user dragged a file into chat), call find_audio_files first. For files over 15 MB or already-hosted audio, use analyze_url.

Input parameters:

- `file_path` (string, required): Absolute path to the audio file on this machine
- `model` (string): core = 1 credit, ultra = 2 credits (deeper analysis)
- `track_name` (string): Display name; defaults to the file name

### `analyze_url` (~70 tokens)

Analyze audio from a URL (any public or signed https link, up to 60 MB) with TrackTag AI. Same output and credit cost as analyze_track.

Input parameters:

- `audio_url` (string, required): Direct link to the audio file
- `model` (string)
- `track_name` (string)

### `get_credits` (~23 tokens)

Get the user's remaining TrackTag credit balance and API limits. Free.

### `list_recent_jobs` (~35 tokens)

List the user's recent TrackTag API analyses (id, status, track, credits). Free.

Input parameters:

- `limit` (integer)
