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

Get an API key

Create a free account — the free plan includes 100 credits every month, no credit card. Copy your key from the dashboard.

Setup

Replace YOUR_API_KEY with your JsonLink key.

Claude Code

claude mcp add jsonlink -e JSONLINK_API_KEY=YOUR_API_KEY -- npx -y jsonlink-mcp

Claude Desktop

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" }
    }
  }
}

Cursor

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" }
    }
  }
}

VS Code

Add this to .vscode/mcp.json:

{
  "servers": {
    "jsonlink": {
      "command": "npx",
      "args": ["-y", "jsonlink-mcp"],
      "env": { "JSONLINK_API_KEY": "YOUR_API_KEY" }
    }
  }
}

Windsurf and other clients

Any client that runs stdio MCP servers works the same way: command npx, arguments -y jsonlink-mcp, environment variable JSONLINK_API_KEY.

Example prompts

• "Read https://example.com/blog/post and summarize it in five bullet points."
• "Take a mobile screenshot of my landing page and tell me what looks broken."
• "Get the title and description of these 10 links and make a table."
• "List the external links on this page that are nofollow."

Configuration

Variable	Description
JSONLINK_API_KEY	Your JsonLink API key (required).
JSONLINK_API_URL	API base URL. Defaults to https://jsonlink.io.

Pricing

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.

Development

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.
