Trust breakdown (6 categories)

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 →

Endpoint Security66

The endpoint's TLS certificate is valid, in date, and uses a strong key. View diagnostics → Pass
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. See how to fix → View diagnostics → Unverified
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 Usability60

AI-judged instruction clarity (excellent).Pass
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. See how to fix → Fail
Usage-examples check failed: none of the tools include examples. See how to fix → Fail

Stability & Change Management27

Stability observed for 8 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

Capabilities100

Implements a supported MCP spec version (2025-11-25); the latest is 2026-07-28.Pass

MCP tools — 3 exposed · ~936 tokens

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.

Tool Tokens

met_get_object Get Met Objects ~135

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 Output Examples

Name	Type	Req	Description
objectIDs	array	yes	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.

Name	Type	Req	Description
failed	array	yes	Object IDs that failed to fetch with per-ID error context.
objects	array	yes	Successfully fetched objects.

No examples provided.

met_list_departments List Met Departments ~47

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.

Input Output Examples

Input schema present but exposes no named parameters.

Name	Type	Req	Description
departments	array	yes	All 19 curatorial departments at The Metropolitan Museum of Art.

No examples provided.

met_search_collections Search Met Collection ~754

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 Output Examples

Name	Type	Req	Description
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	yes	Keyword query, matched across title, artist name, culture, medium, tags, and other text fields. Broad terms return large ID sets.

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

No examples provided.
