How this component scores in each security and reliability category. Every signal is checked automatically against the live server, and we only credit what we can confirm. How we score → Why this is hard to score →
Endpoint Security83
- The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
- No authorisation is required to call this server. Nothing on it is marked destructive, but we can't show that an anonymous caller can only read: full credit needs the server to list at least one tool and every tool to be verifiably read-only. We use a best-effort check of tool names and descriptions to tell read-only tools from tools that change things, so some genuinely read-only tools may not get full credit. Names that start with a read verb (get, list, read, search and similar) and accurate readOnlyHint annotations help. Meet that to earn full credit, or require authorisation. See how to fix → View diagnostics → Partial
- HTTPS is enforced; there's no plaintext access path. View diagnostics → Pass
- The HSTS (Strict-Transport-Security) header is present. View diagnostics → Pass
- DNSSEC is configured correctly; the domain's records validate against the full chain to the root. View diagnostics → Pass
Transport & Reachability100
- Verified streamable-http transport via a live MCP handshake. View diagnostics → Pass
Schema Quality & AI Usability76
- 100% of prompts and resources have a non-trivial description (not blank, and not just the item's name).Pass
- AI-judged instruction clarity (excellent).Pass
- Context-footprint check failed: tool/resource definitions use about 2772 tokens (~252/item across 11 items; 10 tools + 1 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 Management100
- No destabilizing schema changes in the last 30 days.Pass
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 10 captured tool definition(s), and no name or description among them implies an irreversible operation.Pass
- An AI judge read all 12 captured unit(s) of tool text and found none that tries to manipulate the model reading it.Pass
Capabilities100
- Implements a current MCP spec version (2026-07-28).Pass

musicbrainz_browse_entities musicbrainz-mcp-server: browse entities ~488
Paginate entities linked to one parent MBID. Accepted parents by target: artist → area, recording, release, release-group, work; label → area, release; release-group → artist, release; release → area, artist, label, recording, release-group, track_artist; recording → artist, release, work; work → artist. track_artist enumerates releases crediting an artist on tracks but not at release level. Artist release-groups and release-group editions embed one upstream page in get_* lookups; use this tool for the complete entity set. Recording browse returns identities, not performance attributes/dates or ordered release tracks: use musicbrainz_get_recording for work relationships and musicbrainz_get_release for tracks. Provide exactly one valid parent link. offset pages to any depth; totalCount is the exact filtered upstream entity total. Optional type/status filters apply only on supported parent pairs; preserve applied filters on continuation. Release rows carry status, other entity subtypes use type; release-groups include secondaryTypes and recordings include firstReleaseDate when available.

musicbrainz_get_cover_art musicbrainz-mcp-server: get cover art ~241
Cover Art Archive images for a release or release-group MBID: front/back flags, image types, full-resolution URLs, and 250/500/1200px thumbnail URLs. limit defaults to 25 and clamps above 100; offset defaults to 0. Pages retain archive order, totalCount counts all images, and hasArt describes the full archive even on an empty page. Follow the notice for the next offset. No art is a successful empty result; an unknown MBID fails with entity_not_found after a bounded MusicBrainz check. A release-group resolves to a representative release's art. URLs are linked, never rehosted; image copyright stays with rights holders.

musicbrainz_get_work musicbrainz-mcp-server: get work ~221
Work (a composition, distinct from a recording) by MBID: type, languages, ISWCs, ordered work attributes (rights-society registrations, musical key and other metadata), writers/composers/lyricists, movements, arrangements, aliases, tags, and external links. Attributes remain available when relationships are disabled. Follow work target MBIDs with this tool; direction, orderingKey, and targetDisambiguation distinguish parts and arrangements without reordering relationships. This server returns the first 25 recording relationships with their exact total and actual truncation disclosure, preserving all other relationships. Browse recording entities with musicbrainz_browse_entities (target_type=recording, link.work), then use musicbrainz_get_recording for work relationship attributes and dates; browse alone does not return those details.

| cap | number | – | Server-side recording relationship cap, when truncated. |
| disambiguation | string | – | Short qualifier. Omitted when absent. |
| error | object | – | Present when the call failed. Absent on success. |
| externalLinks | array | – | External resource links (url-rels) (may be empty). |
| iswcs | array | – | ISWCs assigned to this work (may be empty). |

musicbrainz_lookup_identifier musicbrainz-mcp-server: lookup identifier ~308
Resolve a standard identifier to MusicBrainz entities without a name search — the deterministic path when you already hold an ID. id_type=isrc → recordings (a recording-level code, often shared by several recordings); id_type=iswc → works (a composition-level code); id_type=barcode → releases (UPC/EAN digits; spaces and hyphens are ignored). ISRC and ISWC hit dedicated exact endpoints; barcode is a Lucene search filter so results are ranked (exact match scores 100). The output kind field tells you which entity type came back.
| Name | Type | Req | Description |
|---|---|---|---|
| id_type | string | yes | Which standard identifier: isrc (recording), iswc (work), or barcode (release). |
| value | string | yes | ISRC: compact CCXXXYYNNNNN or grouped CC-XXX-YY-NNNNN (e.g. GBAYE9701274 or GB-AYE-97-01274), case-insensitive with surrounding whitespace. ISWC: T plus ten digits, optional hyphen after T, optional… |
| Name | Type | Req | Description |
|---|---|---|---|
| error | object | – | Present when the call failed. Absent on success. |
| result | – | – | The resolved entities, discriminated by `kind` (recordings | works | releases). |

musicbrainz_search_entities musicbrainz-mcp-server: search entities ~333
Full-text search across a MusicBrainz entity type (artist, release-group, release, recording, work, label) using a Lucene query string. Returns ranked matches with MBID, name/title, disambiguation, subtype where applicable, release status, release-group secondary types, recording first-release dates, and a 0–100 relevance score (100 = exact). Release rows use status; other entity subtypes use type. Starting point when resolving a name to an MBID — chain the returned MBID into the matching musicbrainz_get_* tool. Results are in MusicBrainz score-descending order. Supports field-scoped Lucene syntax (e.g. `artist:radiohead AND country:GB`). Only the first 500 matches are accessible; narrow the query or use musicbrainz_browse_entities for complete linked sets.
| Name | Type | Req | Description |
|---|---|---|---|
| entityType | string | yes | Which entity type to search. |
| limit | integer | – | Positive integer page size (default 25); values above 100 are clamped to 100 with a notice. With MUSICBRAINZ_CLAMP_OVERSIZED_LIMITS=off, maximum 100 is enforced. |
| offset | integer | – | Result offset for pagination (0-based, below 500). A page crossing the 500-match ceiling is reduced to the remaining window. |
| query | string | yes | Lucene query string; must contain non-whitespace text. Plain text matches names/titles; field scoping (e.g. `artist:`, `country:`, `tag:`) is supported. Sent to MusicBrainz exactly as given. |
| Name | Type | Req | Description |
|---|---|---|---|
| effectiveQuery | string | – | The query string as sent to MusicBrainz. |
| entityType | string | – | The entity type that was searched. |
| error | object | – | Present when the call failed. Absent on success. |
| notice | string | – | Limit clamp and pagination guidance, including zero matches, exhausted pages, and empty-page discrepancies. |
| offset | number | – | The effective zero-based result offset used for this page. |
| results | array | – | Ranked matches, in MusicBrainz score-descending order. |
| totalCount | number | – | Total matches upstream before the limit/offset window. |
