SnapRender — OpenClaw Skill

Give OpenClaw the ability to capture website screenshots using SnapRender.

Quick Install (ClawHub)

clawhub install snaprender

Manual Setup

1. Copy the skill file

mkdir -p ~/.openclaw/skills/snaprender
cp SKILL.md ~/.openclaw/skills/snaprender/SKILL.md

2. Enable in config

Add to ~/.openclaw/openclaw.json:

{
  "skills": {
    "entries": {
      "snaprender": {
        "enabled": true,
        "env": { "SNAPRENDER_API_KEY": "sk_live_your_key_here" }
      }
    }
  }
}

3. Test

openclaw agent --local --session-id test --message "Screenshot stripe.com for me"

Prerequisites

• curl — pre-installed on macOS/Linux
• jq — brew install jq (macOS), apt install jq (Ubuntu)

How It Works

The agent reads the skill description and runs curl via the exec tool to call the SnapRender API. The response is piped through jq to extract the base64 image, which is decoded and saved to /tmp/screenshot.jpg. The agent then reports capture metadata (file size, response time, cache status, remaining credits).

Alternative: Hosted MCP Endpoint

If your client supports MCP (Claude Desktop, Claude Code, Cursor, etc.), you can skip the skill entirely and connect to the hosted endpoint. No install, no curl, no jq — just a URL and your API key.

Claude Desktop

Add to ~/Library/Application Support/Claude/claude_desktop_config.json:

{
  "mcpServers": {
    "snaprender": {
      "type": "streamable-http",
      "url": "https://app.snap-render.com/mcp",
      "headers": {
        "Authorization": "Bearer sk_live_your_key_here"
      }
    }
  }
}

Claude Code

claude mcp add snaprender --transport streamable-http https://app.snap-render.com/mcp -H "Authorization: Bearer sk_live_your_key_here"

Cursor / Any MCP Client

Point your client at https://app.snap-render.com/mcp with an Authorization: Bearer sk_live_... header. Uses Streamable HTTP transport.
