What Gallery is for

Seeing the actual painting. When a conversation turns to Van Gogh's cypresses, a Chola Nataraja or the Great Wave, Gallery returns the museum's own record and a direct image — not a description from memory — along with who made it, when, in what, where it hangs and whether it is public domain.

What it does

One search across three of the largest open-access collections in the world: the Metropolitan Museum of Art (New York, ~490,000 records, CC0 images for public-domain works), the Art Institute of Chicago (~130,000 records, IIIF images) and the Cleveland Museum of Art (~60,000 records, CC0). Results are interleaved by museum and limited to works with images. Each artwork carries title, artist and biography line, date, medium, dimensions, object type, department, culture or period, credit line, on-view status and gallery, public-domain flag, image and thumbnail URLs, museum page and, where the museum wrote one, wall text. An artist tool gathers works across the museums with the Art Institute's dates and biography. Highlights pull the Met's flagged masterpieces, Chicago's boosted works and Cleveland's CC0 works for a topic; an artwork of the day picks deterministically from the Met's highlights. The Met's 19 departments are listed. A movement guide covers 31 movements from the Renaissance to Street Art, including the Bengal School, the Bombay Progressives and contemporary Indian art, with period, place, traits, artists and key works.

What it is not

Not every museum: the Louvre, Prado, Rijksmuseum, Tate and Indian national collections either need keys or have no open API. Full-text search at the Met ranks loosely (it matches credit lines and tags), so highlight results are filtered for relevance where possible. Images of works still in copyright are provided under each museum's terms; check public_domain before reuse.

Tools

Collections

search_artworks — Search artworks with images across the Met, Art Institute of Chicago and Cleveland Museum of Art, interleaved by museum. Use for "Van Gogh paintings", "Japanese woodblock prints", "Chola bronzes". Args: query, sources, limit.

artwork — Full record for one artwork: artist and bio, date, medium, dimensions, department, culture/period, credit, on-view location, public-domain status, image and wall text. Use after search_artworks. Args: id.

artist — An artist's works across the three museums (filtered to that artist where the API allows) plus dates and a short bio when the Art Institute has one. Use for "works by Rembrandt", "who was Amrita Sher-Gil". Args: name, limit.

Discover

highlights — Curated highlights — the Met's 'highlight' objects, the Art Institute's boosted works and Cleveland CC0 works with images — for a topic. Use for "masterpieces of Indian art", "must-see paintings". Args: query, sources, limit.

artwork_of_the_day — A deterministic artwork for today (same answer all day) from the Met's highlights on a theme, with full detail. Use for "art for today", "daily painting". Args: topic.

departments — The Metropolitan Museum's 19 curatorial departments with ids (usable as context for searches).

Learn

art_movement — A guide to an art movement — period, where, traits, key artists and works — or the list of all 31 covered (Renaissance to Street Art, including the Bengal School and the Bombay Progressives). Use for "what is Fauvism", "which movement was Dalí". Args: name.

Conventions

• Read-only. Every tool reads public data or computes; nothing is written anywhere and nothing about the user is stored.
• Result envelope. ok: true with data, or ok: false with a structured error (bad_input, not_found, upstream_error). degraded lists optional sources that were unreachable.
• Rate limits. Free tier 60 tool calls/minute and 300/day per user (keyed on the user identifier supplied by the host agent, else client IP); Pro keys raise this. Over-limit calls return HTTP 429 with Retry-After. initialize and tools/list are never counted.

Gallery — Privacy Policy

Effective 23 September 2026. Unify Dynamics LLC ("we", "us"), Menlo Park, California.

What Gallery is. Gallery is a connector (an MCP server and REST API) that AI assistants and personal agents call on your behalf for art: searching open-access museum collections, artwork and artist details, highlights and an art-movement guide. You interact with your assistant; the assistant sends us only the search words or artwork id needed for the lookup.

What we receive. The arguments of each tool call (search words, an artist name, an artwork id, a movement name), the technical headers needed to serve the request (an IP address or a client identifier supplied by the assistant, and a Pro API key if you have one), and standard server logs.

Lookups are forwarded or computed, not stored. Search words are passed to the museum APIs below; the movement guide is a bundled table. We do not record your queries or build a profile. Nothing you send is stored, logged in request bodies or used to train anything. Successful museum answers are cached in memory for up to a week, keyed by the query.

What we do not receive or store. We do not receive your conversation with the assistant, your name or contacts or any account credentials. Rate-limit counters (a client identifier and timestamps) are held in memory for at most 24 hours. Hosting-provider access logs, which contain IP addresses and request paths but not request bodies, are retained for up to 30 days for security and abuse prevention.

Sub-processors. The Metropolitan Museum of Art, Art Institute of Chicago and Cleveland Museum of Art collection APIs each receive the search words and our server's IP address, never yours. Image URLs in responses point directly at the museums' servers; loading an image is a request from your assistant or browser to that museum. Hosting: Vercel (United States regions).

Legal bases and your rights. For users in California, the EU/UK and elsewhere, our processing is necessary to provide the service you request through your assistant. Because we store no personal data beyond short-lived logs, requests to access, correct or delete personal data are usually satisfied automatically; you can still contact agent@connectorbay.com and we will respond within 30 days. We do not sell or share personal information and do not use your data to train models.

Children. Gallery is a general-audience service; we knowingly collect no personal data from anyone.

Changes. We will post changes here with a new effective date.

Gallery — Terms of Service

Effective 23 September 2026. These terms govern use of the Gallery connector ("the Service") operated by Unify Dynamics LLC ("we", "us").

1. The Service. Gallery returns art information — artwork records and image links from open-access museum collections, artist records, highlights and an art-movement guide — from public museum APIs and a bundled table. It is accessed through an AI assistant or directly over MCP or HTTP.
2. Sources and licences. Collection data from The Metropolitan Museum of Art Open Access (CC0 1.0), the Art Institute of Chicago API (data CC0 1.0; images subject to the museum's image terms and IIIF policy) and the Cleveland Museum of Art Open Access (CC0 1.0). Each record's public-domain flag reflects the museum's own statement; works not in the public domain may be shown for reference but reuse requires the rights holder's permission. The movement guide is editorial content of Unify Dynamics LLC.
3. Reference only. Attributions, dates and provenance are the museums' current catalogue statements and change with research. Image links are the museums' and may move. Nothing here is appraisal or authentication advice.
4. Acceptable use. Do not use the Service to bulk-scrape the sources or to circumvent rate limits. Automated use within the published limits is welcome.
5. Availability. The Service is provided "as is" without warranty. We may change, limit or discontinue it at any time.
6. Data. Our Privacy Policy describes what we process. In short: your query is forwarded to the museum APIs and nothing is stored.
7. Attribution. The Metropolitan Museum of Art; Art Institute of Chicago; Cleveland Museum of Art.
8. Pro keys. Optional Pro API keys are issued at our discretion, are personal to the holder and may be revoked for abuse.
9. Liability. To the fullest extent permitted by law, Unify Dynamics LLC is not liable for any loss arising from use of or reliance on the Service. Our total liability is limited to US $100.
10. Governing law. California law; venue in San Mateo County, California.
11. Contact. Unify Dynamics LLC · agent@connectorbay.com · https://connectorbay.com/gallery
