Measured tools (8)

• list_example_songs read-only

  List real Songbrain analyses of Songbrain's own songs (no API key needed). Use one to show what the API returns before analysing a user's song.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no

• get_example_analysis read-only

  Full analysis of an example song: Song DNA, beat grid and sections, best moments, lyrics, scores, story and shot plan. No API key needed. Summary view by default (no per-word timings or beat arrays); set view='full' for everything.

  Parameters:

  • example_id (required) — string — id from list_example_songs
  • view — string
  • sections — array — Only these sections (default: all)

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no

• get_example_shot_plan read-only

  The beat-synced shot plan of an example song: every scene with start and end seconds, its act (setup, turn or payoff), the image/video prompt, framing, motion and the lyric sung under it, plus the story, world and palette. No key needed.

  Parameters:

  • example_id (required) — string

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no

• get_pricing read-only

  Songbrain API prices (free songs per month, price per song) and limits.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no

• analyze_song

  Start the analysis of a song at a public audio URL (MP3, WAV, FLAC, M4A, AAC, OGG or AIFF; 30 s to 10 min). Needs an API key on the MCP connection. Returns a song_id; poll get_song until status is 'done' (typically 60–90 seconds, up to ~2 minutes when busy). Uses one free song, or 25 credits (mode 'full') / 10 credits (mode 'dna').

  Parameters:

  • audio_url (required) — string — Public http(s) URL of the audio file
  • mode — string — full = Song DNA + video direction (story, shot plan with prompts), 25 credits. dna = Song DNA only (no story, no shot plan), 10 credits. A free song covers either.
  • title — string
  • artist — string
  • lyrics — string — Optional: the song's lyrics as plain text. Used for the exact words (timings still come from the audio).

  Hints: read-only no · destructive no · idempotent not declared · open-world yes

• get_song read-only

  Status of a song started with analyze_song, then its full analysis once done. Summary view by default; view='full' adds word timings and beat arrays.

  Parameters:

  • song_id (required) — string
  • view — string
  • sections — array

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no

• add_video_direction

  For a finished song analysed with mode 'dna': builds its story and beat-synced shot plan (scenes with seconds and image/video prompts) from the existing analysis. 15 credits, refunded if it fails. Then poll get_song (about 30 seconds).

  Parameters:

  • song_id (required) — string

  Hints: read-only no · destructive no · idempotent not declared · open-world no

• get_account read-only

  Free songs left this month, credit balance and price per song for the connected key.

  Hints: read-only yes · destructive not declared · idempotent not declared · open-world no
