## Trust breakdown

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

Scored 2026-08-03.

- **Endpoint Security**: 66/100
  - The endpoint's TLS certificate is valid, in date, and uses a strong key.
  - Authorisation not fully verified: no authorisation is required to call this server, and 3 tool(s) never declared a destructiveHint. The MCP spec treats an absent hint as destructive by default, so we cannot call this surface safe.
  - HTTPS is enforced; there's no plaintext access path.
  - The HSTS (Strict-Transport-Security) header is present.
  - DNSSEC is configured correctly; the domain's records validate against the full chain to the root.
- **Transport & Reachability**: 100/100
  - Verified streamable-http transport via a live MCP handshake.
- **Schema Quality & AI Usability**: 60/100
  - AI-judged instruction clarity (excellent).
  - Context-footprint check failed: tool/resource definitions use about 1033 tokens (~344/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**: 27/100
  - Stability observed for 8 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.
- **Capabilities**: 100/100
  - Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.

## MCP tools (3)

### `met_list_departments` (~47 tokens)

List Met Departments

Return the 19 curatorial departments at The Metropolitan Museum of Art, each with its numeric departmentId and display name — the valid values for the met_search_collections departmentId filter.

Output parameters:

- `departments` (array): All 19 curatorial departments at The Metropolitan Museum of Art.

### `met_search_collections` (~754 tokens)

Search Met Collection

Search the Metropolitan Museum of Art collection by keyword and optional filters. Returns the total match count and a page of matching object IDs, which met_get_object resolves to full records. Relevance is keyword-based, not semantic; department and geographic filters narrow results more than a longer query. The medium parameter maps to the classification field (pass "Paintings", "Drawings", etc., not material descriptions like "Oil on canvas"). isPublicDomain guarantees CC0-licensed images; hasImages also includes copyrighted works. isOnView restricts results to works currently on display in a Met gallery.

Input parameters:

- `dateBegin` (integer): Earliest object date (year, inclusive). Negative integers for BCE (e.g., -500 for 500 BCE). Requires dateEnd.
- `dateEnd` (integer): Latest object date (year, inclusive). Negative integers for BCE. Requires dateBegin.
- `departmentId` (integer): Restrict results to one curatorial department. Valid IDs come from met_list_departments — the Met exposes a sparse set (roughly 1–21, with gaps); an unrecognized ID is rejected with an invalid_depart…
- `geoLocation` (array): Filter by geographic origin. Each value is matched broadly against geography fields and artist nationality. Multiple values are AND-combined — ["France", "Egypt"] returns objects associated with both…
- `hasImages` (boolean): When true, restricts results to objects that have at least one associated image, including copyrighted works whose images cannot be reproduced. isPublicDomain is the filter for freely reusable CC0 im…
- `isHighlight` (boolean): When true, restricts to objects the Met has designated as highlights — major works central to the collection.
- `isOnView` (boolean): When true, restricts results to objects currently on display in a Met gallery. The GalleryNumber field on the met_get_object record identifies the specific gallery.
- `isPublicDomain` (boolean): When true, restricts results to objects released under CC0 open access — free to use without permission or attribution. These objects return direct high-resolution image URLs in met_get_object. Combi…
- `limit` (integer): Maximum number of object IDs to return from the full result set. The Met search returns every match (up to tens of thousands); this caps how many IDs are returned.
- `medium` (string): Filter by object classification (e.g., "Paintings", "Drawings", "Prints", "Ceramics", "Sculpture", "Photographs", "Textiles"). Maps to the classification field on the object, not the materials/medium…
- `offset` (integer): Zero-based index into the full result set to start from (default 0). The nextOffset from a previous response is the value to pass here for the next page; a broad query carries the same timeout risk o…
- `q` (string, required): Keyword query, matched across title, artist name, culture, medium, tags, and other text fields. Broad terms return large ID sets.

Output parameters:

- `nextOffset`: The offset to pass on the next call to continue paging, or null when the result set is exhausted (truncated is false).
- `objectIDs` (array): Object IDs for the first `limit` results.
- `remaining` (integer): Count of matching object IDs after this page: total − (offset + returned), floored at 0. 0 means this is the last page.
- `returned` (integer): Count of object IDs in this response — may be less than `total` when the full result set was truncated by `limit`.
- `total` (integer): Total number of matching objects in the Met collection (may far exceed the returned IDs).
- `truncated` (boolean): True when matching IDs remain beyond this page (offset + returned < total); false when this page is the last.

### `met_get_object` (~135 tokens)

Get Met Objects

Fetch full records for one or more Met Museum object IDs. Accepts up to 20 IDs per call and returns partial success — a single 404 does not fail the whole batch; per-ID failures are reported separately. Object IDs come from met_search_collections. Non-public-domain objects return empty image URLs. The constituents array is null for anonymous or unattributed works; tags is null for untagged objects.

Input parameters:

- `objectIDs` (array, required): One or more Met object IDs to fetch. Maximum 20 per call. IDs come from met_search_collections. Partial failures are reported per ID rather than failing the whole batch.

Output parameters:

- `failed` (array): Object IDs that failed to fetch with per-ID error context.
- `objects` (array): Successfully fetched objects.
