MCP Server

Rendex provides a Model Context Protocol server so AI agents can capture screenshots natively.

Two Ways to Connect

Option 1: Remote Server (Recommended)

Connect directly to mcp.rendex.dev — no installation needed.

Claude Desktop

{
  "mcpServers": {
    "rendex": {
      "url": "https://mcp.rendex.dev/mcp",
      "headers": {
        "Authorization": "Bearer YOUR_API_KEY"
      }
    }
  }
}

Cursor / Windsurf

Add the same configuration in your IDE's MCP settings panel.

Option 2: Local via npx

Run the MCP server locally using stdio transport:

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