# @copperline/rendex-mcp

MCP server for [Rendex](https://rendex.dev) — capture screenshots of any webpage via AI agents using the Model Context Protocol.

## Quick Start

### Claude Desktop / Cursor / Windsurf (npx)

Add to your MCP client config:

```json
{
  "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):

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