The tools this component advertises to a client, with an estimated token cost for each. Expand a tool to see its parameters and schema. The per-tool counts are indicative and are not scored directly; the schema's total context footprint is one signal in Schema Quality & AI Usability. A tool's description is untrusted text the model reads on every call, which is what makes this list a security surface and not just an inventory: how tool poisoning works →
get_lyrics Get lyrics ~346
Fetch the lyrics of one track from LRCLIB, given the id returned by search_tracks, or an exact artist and title. Set 'format' to "synced" for karaoke-style lyrics with a timestamp on every line, "plain" for the text alone, or "both". Check 'has_synced_lyrics' in the search results first: not every track has timed lyrics. Lyrics can be long, so the text is truncated by default: check 'truncated' and call again with 'offset' set to 'next_offset' to continue reading. Instrumental tracks come back with status "instrumental" and no text, which is a valid answer, so do not retry them. Always cite 'attribution' when showing lyrics to a user.
| Name | Type | Req | Description |
|---|---|---|---|
| album_name | string | – | Album name, to pick between releases. |
| artist_name | string | – | Artist name, matched exactly by LRCLIB. Required when 'id' is absent. |
| duration_seconds | number | – | Track duration, to pick between versions of differing length. |
| format | string | – | 'plain' returns the text only. 'synced' returns LRC text plus a parsed list of timestamped lines. 'both' returns each of them. |
| id | integer | – | LRCLIB track id, as returned by search_tracks. Preferred over the name fields. |
| max_chars | integer | – | Maximum characters of lyrics text to return in this call. |
| offset | integer | – | Character offset to resume from, for lyrics longer than max_chars. |
| track_name | string | – | Song title, matched exactly by LRCLIB. Required when 'id' is absent. |
| Name | Type | Req | Description |
|---|---|---|---|
| attribution | string | yes | – |
| next_offset | – | yes | – |
| notes | array | yes | – |
| offset | integer | yes | – |
| paginated_form | string | yes | Which body the character counts and the offset describe. Timed text carries its timestamps, so it is longer than the words alone. |
| plain_lyrics | string|null | yes | – |
| returned_chars | integer | yes | – |
| source | string | yes | – |
| status | string | yes | – |
| synced_lines | – | yes | Parsed timestamped lines. |
| synced_lines_truncated | boolean | yes | – |
| synced_lyrics | string|null | yes | Raw LRC text, one timestamp per line. |
| total_chars | integer | yes | – |
| track | object | yes | – |
| truncated | boolean | yes | – |
No examples provided.
get_track Get track metadata ~95
Look up one LRCLIB track by its id and return its metadata without the lyrics: title, artist, album, duration, and whether plain and time-synced lyrics exist. Use this to confirm you have the right release or version before calling get_lyrics, or to check whether timed lyrics exist for a track id you already hold.
| Name | Type | Req | Description |
|---|---|---|---|
| id | integer | yes | LRCLIB track id, as returned by search_tracks. |
| Name | Type | Req | Description |
|---|---|---|---|
| duration_formatted | string|null | yes | Duration as m:ss, when known. |
| notes | array | yes | – |
| source | string | yes | – |
| track | object | yes | – |
No examples provided.
search_tracks Search tracks ~246
Search LRCLIB for tracks by title, artist or album, and get the id needed to fetch lyrics with get_lyrics. Give either 'query' as free text, or 'track_name' and 'artist_name' separately for a narrower search. Results carry metadata only: title, artist, album, duration, and whether plain and time-synced lyrics exist. Use 'duration_seconds' and 'album_name' in the results to tell releases and re-recordings of the same song apart, and 'has_synced_lyrics' to know whether karaoke-style timed lyrics are available before fetching them. LRCLIB indexes tracks by their metadata, so it cannot search for a word appearing inside the lyrics.
| Name | Type | Req | Description |
|---|---|---|---|
| album_name | string | – | Album name, to narrow a structured search. |
| artist_name | string | – | Artist name, for a structured search. |
| limit | integer | – | Maximum tracks to return. LRCLIB returns up to 20 per search. |
| query | string | – | Free-text search, for example 'nino ferrer le sud'. Use this or the fields below. |
| track_name | string | – | Song title, for a structured search. |
| Name | Type | Req | Description |
|---|---|---|---|
| notes | array | yes | – |
| result_count | integer | yes | – |
| results | array | yes | – |
| source | string | yes | – |
| total_available | integer | yes | Tracks LRCLIB returned before applying 'limit'. |
