Est-ce que io.betterimage/betterimage est sûr ?

Au dernier audit MCP Hub, le serveur MCP « io.betterimage/betterimage » est classé « Non encore testé ». Référencé dans l'annuaire. Seul le pentest comportemental fait foi, et il n'a pas encore été exécuté sur ce serveur. Le verdict est réévalué en continu ; consultez la fiche pour l'état à jour.

Méthode : MCP Hub analyse la description de chaque outil (couche 1) et, pour le verdict fort, exécute le serveur dans une micro-VM isolée avec leurres et réseau bloqué (couche 2). On publie des noms et des compteurs, jamais le contenu brut renvoyé par un outil.

Les 10 outils

• card_from_url≈ 1122 tokens

  Make a social card for a page that already exists, in one call: fetches the page like a crawler, takes its title, description, author, domain and site icon, picks the starter design that fits the page (a Jev decision over every preset, about 100 ms) and returns the image (shown inline, watermarked, free). Use this first when the user gives a URL: "make an OG image for my latest post". Any field you pass overrides what the page says. Pass preset (see list_presets) to choose the design yourself, or a size. No API key needed; one page fetch plus one render per call.

  • url · string · requis
    The page URL, e.g. https://example.com/blog/my-post.
  • size · string · optionnel · og | youtube | square | portrait | story | pinterest
    Output canvas: og (1200x630), youtube (1280x720), square (1080x1080), portrait (1080x1350), story (1080x1920), pinterest (1000x1500). Defaults to the template's own size, usually og (1200x630, the link preview size). Layouts restack automatically on square and vertical canvases.
  • fields · object · optionnel
    What to put on the card. Text fields replace the template's text; the *_url fields replace its pictures, fetched server-side. Omit a field to keep what the template has. Design - colours, fonts, layout, crop framing - never changes.
  • preset · string · optionnel
    Preset key from list_presets. Omit it to let Jev pick the design that fits the page (the result names the pick and its runners-up). Fallback when no pick is possible: og-essay-light.

• check_link_preview≈ 216 tokens

  Fetch a public page the way X, Facebook, LinkedIn, Slack and Discord crawlers do and report what they will show: the effective title, description and image per platform, the og:image's real format, dimensions and weight, and a list of concrete problems with fixes. Use when a user asks why their link looks wrong when shared, or before publishing. Only http(s) URLs on the public internet; one page fetch plus up to two image fetches per call. No API key needed.

• generate_meta_tags≈ 431 tokens

  Build the complete <head> block for a page: <title>, meta description, canonical, Open Graph and Twitter card tags, with og:image width/height. Returns HTML to paste plus notes on anything worth fixing (title too long, image over http). Use after check_link_preview, or whenever a user needs the tags for a new page. No API key needed; nothing is fetched.

• list_presets≈ 351 tokens

  Browse the ready-made designs (presets) a card can start from: key, name, template kind, native size, use-case categories, a one-line look description and a preview image URL. Start here when the user wants a social card and has no saved template. Then call preview_card with the chosen key. No API key needed.

• list_templates≈ 142 tokens

  The user's saved templates (their own designs, made in the editor or with save_template): slug, name, kind, the fields render_card and og_image_url can override, and when it was last edited. Needs an API key. Call this before render_card or og_image_url when you do not know the slug.

• og_image_url≈ 1087 tokens

  Build a signed image URL for a saved template with the given text, ready to put in a page's <meta property="og:image"> tag. Nothing is rendered now: the image is generated when a crawler fetches the URL, cached at the edge for a day, and each uncached fetch spends one image of the monthly quota. Needs an API key. This is the zero-infrastructure way to give every page its own card; use it in page templates, CMS hooks and static site generators. Returns the URL and the ready meta tag.

• preview_card≈ 1017 tokens

  Render a preset with the user's text and return the image (shown inline). Free, no API key; the preview carries a small betterimage.io watermark and does not touch any quota. Use it to show the user what their card will look like before they commit. For a clean image: save_template + render_card on a paid API plan, or the one-off clean download in the editor.

• render_card≈ 1036 tokens

  Render one of the user's saved templates with the given text and return the PNG (shown inline, at 1x). Needs an API key. On a paid plan the image is clean (no watermark); on the free tier it is watermarked. Each call spends one image of the monthly quota. Use it when the user wants the actual file, e.g. to host it themselves. For an og:image tag that needs no hosting, or for a 2x retina file, prefer og_image_url.

• save_template≈ 1052 tokens

  Copy a preset (optionally with the user's text as its new defaults) into the user's account as a saved template, so render_card and og_image_url can use it. Needs an API key. Do this once per design, not per image: afterwards every render only passes the text that changes. Returns the slug to use next and a link to fine-tune the design in the editor.
