JsonLink MCP Server
Give your AI agent the web. The JsonLink MCP server lets Claude, Cursor, VS Code and any MCP client read web pages as Markdown, get link metadata, take screenshots and list the links and images on any URL.
- Reads JavaScript-heavy pages — pages are loaded in a real browser when needed.
- Gets past blocks — requests are retried through a proxy when a site blocks them.
- Failed requests are free — timeouts and pages that can't load cost no credits.
Tools
| Tool | What it does | Credits |
|---|---|---|
url_to_markdown | Main content of a page as clean Markdown, for reading articles, docs and blog posts | 1 |
extract_metadata | Title, description, preview images, favicon and site name of a URL | 1 |
screenshot | Screenshot of a page (desktop, mobile, tablet, full page or one element), returned as an image. Ads, trackers, chat widgets and cookie banners hidden; optional dark mode | 2 |
extract_links | Every link on a page with anchor text, follow/nofollow and internal/external | 1 |
extract_images | Every image on a page with format, dimensions and file size | 1 |
