Skills
search_images

Search the MemeStack image gallery. Runs semantic AI and keyword matching in parallel and merges results. Returns images with captions, tags, zap stats, and URLs.

get_image

Get full metadata for a specific image by ID, including caption, alt text, tags, OCR text, zap stats, and URLs.

find_similar

Find visually similar images using perceptual hash matching. Returns images that look alike.

find_related

Find semantically related images using AI embedding similarity. Returns images with similar meaning/topic.

browse_images

Browse and filter the image gallery without a search query. Useful for discovering content by tag, trending, or recent uploads.

get_user_profile

Get a user's public profile including display name, stats, and avatar info.

get_leaderboard

Get top-ranked images by zaps received, or top zappers by amount zapped, over a time period.

browse_by_tag

Browse images for a specific tag. Returns the tag profile (description, stats) and optionally a paginated list of images tagged with it.

browse_by_category

Get a category and its featured images. Categories group related tags (e.g. "charts", "memes", "lightning-network").

list_categories

List all available image categories. Use this to discover what categories exist before calling browse_by_category.

get_tag_profile

Get the profile for a tag (description, image count, total zaps, related tags) without fetching any images. Use browse_by_tag to also retrieve images.

get_mutation_group

Get all variants of a meme template tracked on MemeStack. Returns the dominant image plus every variant in the same mutation group, with citation blocks for each. Use this to research how a meme has evolved or to find variants of a known image.

search_text_in_image

Search for images by the text written or printed in them (OCR). Different from regular search — only matches the text_in_image field, not captions or tags. Use this to find screenshots of specific quotes, signs, watermarks, or memes with specific embedded text.

find_meme_for_text

Find a meme that captures a vibe, idea, or concept. Returns ready-to-embed images with citation blocks. Use this when writing posts, articles, or social content and you need a meme to illustrate a point.

popular_tags

List the most-used tags on MemeStack by all-time usage count. (Time-period filtering is not yet supported — tag usage is currently counted across the full lifetime of each tag.)

tag_autocomplete

Suggest tag slugs matching a prefix. Use this to verify a tag exists before filtering by it, or to discover related tags. Prefix must be ≥ 2 characters.

cite_image

Generate canonical attribution blocks for one or more MemeStack images. Returns markdown, HTML, and plain-text citation strings ready to paste into your output, plus a combined block for citing multiple images at once.

reverse_image_search

Find MemeStack images that look visually similar to a given image. Accepts an HTTPS image URL or a `data:image/...;base64,...` URL for bytes pasted into agent context. Returns visually-similar matches via perceptual-hash (dHash) hamming distance, with citation blocks. Heavily rate-limited (10/min/IP) since each call hashes the input.

submit_image

Submit an image to MemeStack. Currently in preview — see https://memestack.ai/mcp/agent-tier for access details.
