Sandbox

A public, unauthenticated endpoint that returns fixture ad data so you can test integrations and audits without an account.

Endpoint

curl https://mcp.useproxy.dev/sandbox

No token, no account, no rate limit concerns. It returns the shape of a get_meta_ads result with two fixture ads:

{
  "mode": "sandbox",
  "tool": "get_meta_ads",
  "auth_required": false,
  "result": {
    "success": true,
    "brand": "Nike",
    "platform": "meta",
    "count": 2,
    "ads": [
      { "ad_id": "sandbox_001", "page_id": "15087023444", "media_type": "IMAGE", "status": "ACTIVE", "ad_url": "https://www.facebook.com/ads/library/?id=sandbox_001" }
    ]
  }
}

What it is for

• Verifying the response shape before wiring up a client
• Automated readiness audits that cannot complete OAuth
• Demoing the tool output without spending credits
