Lightdrift Images MCP

Server Details

Search over 1.85 million captioned images using text, a reference image, or both. Upload a JPEG, PNG, or WebP image as base64, or provide a public HTTPS image URL. Find similar images from a Lightdrift asset ID and retrieve hosted file URLs, source licenses, and attribution. Connect with OAuth or an API key. Searches cost $0.005 ($5 per 1,000); image details are free. Setup: https://docs.lightdrift.ai/guides/images-mcp

Disambiguation5/5

Each tool has a clearly distinct role: search_images for discovery from text/image/URL, find_similar_images for asset-to-asset similarity, and get_image for metadata retrieval by known ID. Descriptions explicitly cross-reference one another and state when to use the alternatives, leaving little room for misselection.

Naming Consistency4/5

All names use snake_case verb_noun form (search_images, get_image, find_similar_images), which is predictable and readable. The only minor wrinkle is the near-synonym split between 'search' and 'find' for two search-style operations.

Tool Count4/5

Three tools is on the lean side but matches a tightly scoped image-discovery server, and each tool covers a genuinely different retrieval path. It would feel thin only if users expect downloading, license management, or credit-balance operations.

Completeness4/5

The surface covers the core discovery-to-inspection lifecycle (search, find similar, fetch metadata/rights) with no dead ends for the stated purpose. Gaps like downloading files, managing saved collections, or checking remaining credits are minor and workable outside the toolset.
