  • Pass
    Lists tools

    tools/list returned 6 tools.

  • Pass
    Current protocol

    Negotiated 2025-11-25. The bar is 2025-06-18 or newer.

  • Pass
    HTTPS

    The endpoint URL is https.

Performance

  • Not measured
    Fast (p50)

    Median latency 69 ms over 1 samples in 7 days. The bar is 1000 ms. Need at least 5 samples.

  • Not measured
    Consistent (p95)

    95th percentile 69 ms over 1 samples in 7 days. The bar is 3000 ms. Need at least 20 samples.

  • Not measured
    Reliable (uptime)

    1 of 1 attempts returned a tool list in 30 days (100%). The bar is 99%. Need at least 30 samples.

  • Not measured
    Stable tool list

    Fewer than two successful probes in 30 days, so tool-list stability is not measured.

Access

  • Pass
    Open access

    tools/list succeeded with no credential, and the record declares none.

  • Not measured
    Standard auth

    Auth is not required, so the OAuth metadata check does not apply.

    Every tool description is at least 20 characters.

  • Pass
    Valid input schemas

    Every inputSchema is a JSON Schema object.

    Parameters documented

    25 of 25 parameters have a description (100%). The bar is 80%.

  • Pass
    Safety hints

    Every tool sets readOnlyHint or destructiveHint.

Publisher

  • Pass
    Verified namespace

    Listed in the Official MCP Registry.

  • Not measured
    Website matches publisher

    This namespace is not a reverse domain, so the website comparison does not apply.

  • Fail
    Source repo linked

    No repository URL is on file.

  • Fail
    Repo owner matches

    The GitHub repository owner does not match the namespace login.

brief

Turn card ids into paste-ready prompt blocks, worded verbatim from the cards: IMAGE PROMPT, VIDEO PROMPT, PALETTE (hexes), TYPE, SUNO STYLE and SUNO EXCLUDE, SITE PROMPT, or for job game: KEY ART, CAPSULE, SPRITE/TILESET, UI MOCKUP, MUSIC; for job drama: SHOT blocks for the hook, twist and payoff plus BEATS (timing, shot, what happens, a placeholder line with its length rule), END CARD (title, promise, call to action, set in the type card), CAPTION RULES (safe band y 210 to 1345 on 1080x1920, nothing in the bottom 30%) and DON'T. Pass the ids from deal_hand (or find_styles), at most one card per suit, except camera: several camera cards make a shot list (one SHOT block each). A camera card of kind light lights every shot; a film card of kind fx adds a post effect. tool respells the blocks: midjourney (--ar, --style raw, --sref with the film card's example image), runway or kling (camera line first, 5 or 10 s clips), suno (music blocks only). seconds splits a running time over the shots, beats says what happens in each, vocals picks lyrics or instrumental. A lens card in a shot list shapes every shot. Example: {"hand_ids": ["film-gold-200", "camera-closeup", "color-golden-hour"], "job": "photo", "subject": "an older woman teaching a young man to dance", "tool": "midjourney"}. Drama example: {"hand_ids": ["type-futura", "film-vision3-500t", "color-blue-hour", "camera-closeup", "camera-pull", "camera-push"], "job": "drama", "subject": "a meal-kit app", "feeling": "a quiet breakup at a dinner table", "title": "Dinner for Two", "seconds": 30}. Also returns the don't-list, tone words, deliverables, lint warnings and a site_url.

Discovered
deal_hand

Start here whenever someone asks for an image, video or music prompt, a photo or film look, or art direction from a description ("a moody product shot of perfume", "rainy cafe at night", "a Suno style for a sad song"): deal one matched card per slot for the job from their plain-language feeling. photo = one image (film, camera, color, light); still = image with title type; cover = album or poster art (film, color, type); video or reel = clip or short (film, camera, color, type, score, light); lyric = lyric video (same as reel); song = music only (score); site = website (film, color, type, web); game = key art, store capsule, sprites, UI and loop music (film, color, type, score); drama = a short drama ad where the ad is the show (film, camera, color, type, score, light, and three shots: hook, twist, payoff); all = every suit. Example: {"feeling": "lonely astronaut on a desert planet at dusk", "job": "video", "shots": 3}. Same seed + same inputs = same hand; a new seed re-deals; hold keeps chosen cards ({"film": "film-gold-200"}). For job drama the hand also carries three shots (hook close-up, twist reveal, payoff wide or push) and the look is dealt from the feeling, with the subject read as the product. Returns the hand (slot to card id and name), the main paste-ready prompt for the job (prompt), why each card was picked, clashes, and a site_url showing the hand with pictures. Show the user the prompt and the site_url; use brief with the hand ids for every block (shot lists, palette, Suno, Midjourney spelling).

Discovered
find_styles

Search the 789 cards by feeling, mood, era, technique or style name. Use it when someone names or describes a specific look, lens, film stock, light, palette, font or music style ("what does Portra 400 look like", "ring light macro", "Wes Anderson-style symmetry" finds Planimetric Tableau), to identify a named look ("Kodak Gold" finds Gold 200), to find a replacement for one card in a hand, or to browse one suit. Examples: {"query": "film noir"}, {"query": "90s camcorder"}, {"query": "cozy rainy", "suit": "color"}, {"query": "bossa nova", "suit": "score", "top": 3}. Returns ranked cards (id, suit, kind, name, what, example image). When nothing matches directly it says so and returns related styles or did-you-mean suggestions. For a full matched set of cards for a project use deal_hand instead.

Discovered
lint_hand

Check card ids you combined yourself for clashes before briefing: black-and-white film with a colour grade, two grades stacked, daylight with a night palette, an anamorphic lens in a vertical frame, an interior light with an outdoor subject. Example: {"hand_ids": ["film-pushed-bw-1600", "color-teal-orange"], "aspect": "9:16"}. ok: true means clean. deal_hand and brief already lint their own output.

Discovered
list_suits

Card counts per suit and per kind (for example camera: shot, move, lens, light). Use it to see what the lookbook covers before searching.

Discovered
show_card

One card in full: what it is, the prompt wording ("ask"), what not to do, feels, moods, pairs, swatch hexes or font details, plus image, clip and music_sample URLs when it has them. Example: {"id": "film-gold-200"}. A wrong id returns did-you-mean suggestions.
