Que pouvez-vous faire avec betterimage.io ?
card_from_url: a social card for an existing page, in one call. Fetches the page like a crawler, picks the design that fits it, returns the image (watermarked preview).list_presets: the 100 starter designs with key, size, categories and preview image.preview_card: render a preset with your text (watermarked preview, no quota).check_link_preview: what X, Facebook, LinkedIn, Slack and Discord will show for a URL, with concrete fixes.generate_meta_tags: the complete<head>block with Open Graph and Twitter tags.list_templates,save_template: your saved designs.render_card: a clean PNG from a saved template (paid plans; watermarked on the free tier).og_image_url: a signed og:image URL rendered on first fetch and cached at the edge, so every page gets its own card with no hosting.
Installation
Ajoutez ceci à la configuration MCP de votre client (Claude Desktop : claude_desktop_config.json ; Cursor : .cursor/mcp.json ; VS Code et les autres utilisent la même forme « mcpServers »).

betterimage.io MCP server
Social cards and OG images for your AI assistant. Give Claude, Cursor, VS Code or any MCP client a page URL and get back a link-preview card on a design picked to fit the page; browse 100 starter designs, preview them with your own text, check how a link previews on X, LinkedIn, Slack and Discord, generate Open Graph and Twitter tags, and with an account save templates, render clean images and get signed og:image URLs that need no hosting.
Every image is rendered from a designed template by a deterministic renderer: the text changes, layout, fonts and colours stay on-brand. No generative image model is involved.
This repository holds the public distribution files for the hosted server (install manifests, registry metadata). The server itself runs at **https://betterimage.io/mcp** and is documented at https://betterimage.io/mcp.

No account needed:
card_from_url: a social card for an existing page, in one call. Fetches the page like a crawler, picks the design that fits it, returns the image (watermarked preview).list_presets: the 100 starter designs with key, size, categories and preview image.preview_card: render a preset with your text (watermarked preview, no quota).check_link_preview: what X, Facebook, LinkedIn, Slack and Discord will show for a URL, with concrete fixes.generate_meta_tags: the complete<head>block with Open Graph and Twitter tags.
With an account (OAuth or API key):
list_templates,save_template: your saved designs.render_card: a clean PNG from a saved template (paid plans; watermarked on the free tier).og_image_url: a signed og:image URL rendered on first fetch and cached at the edge, so every page gets its own card with no hosting.get_usage: plan, watermark status and monthly quota.
Every render tool's fields object also takes the card's pictures by URL -
image_url, image2_url, logo_url and background_url - fetched
server-side and drawn in the slot the design already lays out. That is what
turns one saved template into a whole catalogue: one card per product, same
colours, fonts and crop framing. PNG, JPEG or WebP up to 5 MB, decided by the
bytes rather than the URL; the fetch is SSRF-hardened and a URL pointing back
at betterimage.io is refused.
Every tool carries a title and readOnlyHint/destructiveHint annotations; the two write tools are save_template and render_card.
