Looks things up and changes nothing. Claude Code: allow.

### `met_get_object`

- The name "met_get_object" says "get": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Fetch full records for one or more Met Museum object IDs. Fetches up to 20 distinct IDs per call; a list of up to 500 (a full search or list page) is accepted, and the distinct IDs past the first 20 come back unrequested in remainingIDs for a follow-up call. 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 (keyword search) or met_list_objects (browse by department or update date). Non-public-domain objects return empty image URLs. The constituents array is null for anonymous or unattributed works; tags and measurements are null when the Met records none. Records are returned whole and never truncated, so a batch of unusually large records may return fewer than requested — any that did not fit are listed in deferred[] with their sizes, to be re-requested in a follow-up call. Set includeImages to also receive the CC0 images of up to 3 returned records as image content a vision-capable model can look at.
```

### `met_list_departments`

- The name "met_list_departments" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Return the 19 curatorial departments at The Metropolitan Museum of Art, each with its numeric departmentId and display name — the valid values for the departmentId filter on met_search_collections and met_list_objects.
```

### `met_list_objects`

- The name "met_list_objects" says "list": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Browse the Metropolitan Museum of Art collection without a keyword: every object ID in one curatorial department, every object whose record was created or revised on or after a date, or both together. Returns the total count and one page of IDs in ascending order, which met_get_object resolves to full records. With no filter the list is the whole collection (over 500,000 IDs). departmentId takes an ID from met_list_departments; updatedSince takes a YYYY-MM-DD date and answers "what has the Met added or revised since this day". Paging has no depth limit — pass nextOffset to continue. For keyword, classification, place, or object-date filters use met_search_collections instead. A list is cached for up to an hour, so a record revised within the last hour may not appear yet.
```

### `met_search_collections`

- The name "met_search_collections" says "search": a word for reading.

Description, as the server wrote it:

```untrusted-server-text
Search the Metropolitan Museum of Art collection by keyword and optional filters. Returns the total match count and one 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. Paging reaches only the first 10,000 matches of any search, so narrow a larger one with filters. The medium parameter takes an object classification as the Met spells it ("Paintings", "Sculpture"), not a material like "Oil on canvas". hasImages also includes copyrighted works; CC0 status is per object, from the isPublicDomain and hasCC0Image fields on met_get_object. isHighlight accepts true only. isOnView restricts results to works currently on display in a Met gallery.
```
