Available components
How this component scores in each security and reliability category. Every signal is checked automatically from public evidence about the published package, including repeated runs of it in an isolated sandbox, and we only credit what we can confirm. How we score →
Supply Chain Security87
- No malware found by supply-chain analysis.Pass
- Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree.Partial
- No install/post-install scripts declared.Pass
- Only part of the dependency tree could be resolved (95 of 99), so this covers what we could see, not the whole tree. View diagnostics → Partial
Provenance & Transparency97

- Disclosure check failed: no security disclosure policy was found in the source repository. See how to fix → Fail
Schema Quality & AI Usability69
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 792 tokens (~264/item across 3 items; 3 tools + 0 resources), over budget; trim descriptions and params. See how to fix → Fail
- Usage-examples check failed: none of the tools include examples. See how to fix → Fail
Stability & Change Management0
- Stability not yet verified: not enough scan history yet (needs a 30-day window).Unverified
Tool Coverage100
- 100% of tools have a non-trivial description (not blank, and not just the tool's name).Pass
- 100% of tool parameters carry a description.Pass
- Structured output schemas are declared (100% of tools); any adoption earns full credit.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass
Unverified: 1 category
A category scored 0 because we could not verify it: a data source with nothing on this package, evidence we could not reach, or a check we could not run. We only credit what we can confirm.

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. |

| attribution | string | 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'. |
