## Trust breakdown

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. Scores are 0–100 per category. Scoring method: https://verifymcp.io/docs/scoring (what has changed: https://verifymcp.io/docs/scoring/changelog)

- **Provenance & Transparency**: 48/100
  - Source repository is publicly reachable at the declared URL.
  - Provenance check failed: no build-provenance attestation is published.
  - Clear OSI-approved license (MIT).
  - Actively maintained (last published 22 days ago).
  - Publishes a security disclosure policy (SECURITY.md).
- **Schema Quality & AI Usability**: 68/100
  - AI-judged instruction clarity (excellent).
  - 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.
  - Usage-examples check failed: none of the tools include examples.
- **Stability & Change Management**: 63/100
  - Stability observed for 19 of 30 days with no destabilising changes; credit accrues until the full window elapses.
- **Tool Coverage**: 100/100
  - 100% of tools have a non-trivial description (not blank, and not just the tool's name).
  - 100% of tool parameters carry a description.
  - Structured output schemas are declared (100% of tools); any adoption earns full credit.
- **Tool Safety**: 100/100
  - No prompt-injection markers were found in the server instructions, tool names or descriptions we captured.
  - We read all 3 captured tool definition(s), and no name or description among them implies an irreversible operation.
  - An AI judge read all 4 captured unit(s) of tool text and found none that tries to manipulate the model reading it.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (3)

### `search_tracks` (~246 tokens)

Search tracks

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.

Input parameters:

- `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.

Output parameters:

- `notes` (array)
- `result_count` (integer)
- `results` (array)
- `source` (string)
- `total_available` (integer): Tracks LRCLIB returned before applying 'limit'.

### `get_lyrics` (~346 tokens)

Get lyrics

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.

Input parameters:

- `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.

Output parameters:

- `attribution` (string)
- `next_offset`
- `notes` (array)
- `offset` (integer)
- `paginated_form` (string): Which body the character counts and the offset describe. Timed text carries its timestamps, so it is longer than the words alone.
- `plain_lyrics`
- `returned_chars` (integer)
- `source` (string)
- `status` (string)
- `synced_lines`: Parsed timestamped lines.
- `synced_lines_truncated` (boolean)
- `synced_lyrics`: Raw LRC text, one timestamp per line.
- `total_chars` (integer)
- `track` (object)
- `truncated` (boolean)

### `get_track` (~95 tokens)

Get track metadata

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.

Input parameters:

- `id` (integer, required): LRCLIB track id, as returned by search_tracks.

Output parameters:

- `duration_formatted`: Duration as m:ss, when known.
- `notes` (array)
- `source` (string)
- `track` (object)

## Common questions

### What is the io.github.smeet666/mcp-lrclib server?

io.github.smeet666/mcp-lrclib is listed in the public MCP registry as io.github.smeet666/mcp-lrclib. Search tracks on LRCLIB and fetch plain or time-synced (LRC) lyrics. No API key. This page covers its MCPB bundle (https://github.com/smeet666/mcp-lrclib/releases/download/v2.0.1/mcp-lrclib-2.0.1.mcpb).

### Is the io.github.smeet666/mcp-lrclib server safe to use?

io.github.smeet666/mcp-lrclib scores 53 out of 100 on VerifyMCP. It declares no install or post-install scripts. That is a record of what we were able to check automatically, not an endorsement. The category breakdown on this page shows every signal behind the number, including the ones we could not confirm.

### 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.
