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 → Why this is hard to score →
Supply Chain Security13
- Malware scan not yet available for this package.Unverified
- Known CVEs could not be checked: this artifact ships no SBOM, so there is no dependency list to read. Publishing one would let us assess it.Unverified
- No install/post-install scripts declared.Pass
- Dependency health could not be checked: this artifact ships no SBOM, so there is no dependency list to read. Publishing one would let us assess it.Unverified
Provenance & Transparency48
- Source repository is publicly reachable at the declared URL. View diagnostics → Pass
- Provenance check failed: no build-provenance attestation is published. See how to fix → View diagnostics → Fail
- Clear OSI-approved license (MIT).Pass
- Actively maintained (last published 22 days ago).Pass
- Publishes a security disclosure policy (SECURITY.md).Pass
Schema Quality & AI Usability68
- 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 Management63
- Stability observed for 19 of 30 days with no destabilising changes; credit accrues until the full window elapses.Partial
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
Tool Safety100
- No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.Pass
- We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

Provenance No attestation
The registry publishes no build provenance for this version, so there is nothing to verify.

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 | – | yes | – |
| returned_chars | integer | yes | – |
| source | string | yes | – |
| status | string | yes | – |
| synced_lines | – | yes | Parsed timestamped lines. |
| synced_lines_truncated | boolean | yes | – |
| synced_lyrics | – | 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 | – | 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'. |

What tools does the io.github.smeet666/mcp-lrclib server expose?
io.github.smeet666/mcp-lrclib exposes 3 tools: search_tracks, get_lyrics, get_track. Their descriptions and schemas cost roughly 687 tokens of context every time the server is loaded.
What licence is the io.github.smeet666/mcp-lrclib server under?
io.github.smeet666/mcp-lrclib declares the MIT licence, which is OSI-approved. That covers the source only, and says nothing about the cost of any service it calls.
