Alt text generator for images, plus a free scan for images missing alt text on any web page using AI
About
AltTextGeneratorAI MCP lets your AI assistant generate SEO-friendly, accessible alt text for images and find the images that are missing alt text on any web page.
Give it an image URL or a file on your computer and it writes a short, clear description in 130+ languages. Point it at a web page and it lists every image with a missing or empty alt attribute, for free. Ask it to also write the alt text and it returns a suggestion for each image, ready to add to your site.
Tools: - generate_alt_text: alt text for an image URL - generate_alt_text_from_file: alt text for a local JPEG, PNG, GIF or WebP file (up to 3 MB) - audit_page: finds images without alt text on a page (free), with optional alt text suggestions - check_credits: shows your remaining credits
Built for SEO and accessibility work (WCAG, ADA), content teams, developers and store owners. It needs an AltTextGeneratorAI API key.
