@copperline/rendex-mcp

MCP server for Rendex — capture screenshots and PDFs of any webpage via AI agents using the Model Context Protocol.

Quick Start

Claude Desktop / Cursor / Windsurf (npx)

Add to your MCP client config:

{
  "mcpServers": {
    "rendex": {
      "command": "npx",
      "args": ["-y", "@copperline/rendex-mcp"],
      "env": {
        "RENDEX_API_KEY": "your-api-key"
      }
    }
  }
}

Where to add this:

| Client | Config location | |--------|----------------| | Claude Desktop | ~/Library/Application Support/Claude/claude_desktop_config.json (macOS) | | Cursor | .cursor/mcp.json in project root, or Settings > MCP | | Windsurf | Settings > MCP Servers |

Claude Code (CLI)

Add a .mcp.json to your project root with the same config above. Then restart Claude Code.

Important: Add .mcp.json to your .gitignore — it contains your API key.

Remote (zero-install)

Connect directly — no installation needed (Claude Desktop only):

{
  "mcpServers": {
    "rendex": {
      "url": "https://mcp.rendex.dev/mcp",
      "headers": {
        "Authorization": "Bearer your-api-key"
      }
    }
  }
}
