Compared with every active server in this category in the registry. Stars count only when the publisher owns the repo.
It passed 1 of 1 applicable basic checks. We have not read the code. Before adding a key or token, see what access the server asks for and use a key with only the permissions you need.
You need to fill in: JSONLINK_API_KEY
It runs on your computer. Your AI app starts it when needed, and data does not pass through the maker’s servers (unless it calls an online service itself).

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.
| 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 |

Replace YOUR_API_KEY with your JsonLink key.
claude mcp add jsonlink -e JSONLINK_API_KEY=YOUR_API_KEY -- npx -y jsonlink-mcp
Add this to claude_desktop_config.json (Settings → Developer → Edit Config):
{
"mcpServers": { "jsonlink": { "command": "npx", "args": ["-y", "jsonlink-mcp"], "env": { "JSONLINK_API_KEY": "YOUR_API_KEY" } } } }
Add this to ~/.cursor/mcp.json (or .cursor/mcp.json in a project):
{
"mcpServers": { "jsonlink": { "command": "npx", "args": ["-y", "jsonlink-mcp"], "env": { "JSONLINK_API_KEY": "YOUR_API_KEY" } } } }
Add this to .vscode/mcp.json:
{
"servers": { "jsonlink": { "command": "npx", "args": ["-y", "jsonlink-mcp"], "env": { "JSONLINK_API_KEY": "YOUR_API_KEY" } } } }
Any client that runs stdio MCP servers works the same way: command npx, arguments -y jsonlink-mcp, environment variable JSONLINK_API_KEY.
| Variable | Description |
|---|---|
JSONLINK_API_KEY | Your JsonLink API key (required). |
JSONLINK_API_URL | API base URL. Defaults to https://jsonlink.io. |
Every tool call uses credits from your JsonLink plan: 1 credit per page, 2 per screenshot. Plans start at $15/month for 50,000 credits — see pricing. Credits and rate limits are the same as the REST API.
npm install
npm run build JSONLINK_API_KEY=YOUR_API_KEY node dist/index.js
Run it as a remote (Streamable HTTP) server with node dist/index.js --http --port 3100; clients send their key as Authorization: Bearer YOUR_API_KEY.
