Smithsonian Mcp Server

Wraps the Smithsonian Open Access API to search across 19.4 million catalog objects from 20+ museums and retrieve CC0-licensed images. Exposes five tools: full-text search with filters (museum, decade, culture, object type), single-object metadata retrieval, CC0-gated image access at multiple resolutions, category-based browsing (by museum, culture, period, or medium), and cross-collection discovery via parallel metadata fan-out. Requires a free api.data.gov key. Reach for this when you need programmatic access to Smithsonian collections with guaranteed open-access media, or when you want to surface unexpected connections across NMNH, NASM, SAAM, and other units. Built on the developer's mcp-ts-core framework with STDIO and streamable HTTP transports.
