ByteDance's Trae IDE added MCP support in 2025 - add OTPBox as a project or global server and Trae's agent mode can drive signup flows end-to-end.
Mint a free key first (no account, no card):
curl -X POST https://otpbox.io/api/v1/keys/free -H "content-type: application/json" -d '{}'
→ { "id": "lic_...", "key": "...", "plan": "free", "quotaLimit": 200 }
Add to .trae/mcp.json (project) or via Trae's MCP settings panel (global):
{
"mcpServers": {
"otpbox": {
"url": "https://otpbox.io/mcp",
"headers": { "Authorization": "Bearer <your-otpbox-key>" }
}
}
}
.trae/mcp.json with a real key in it - use Trae's global settings for a personal key, or an environment-variable reference if your version supports it.Once connected, Trae can call OTPBox's 13 MCP tools directly. For example:
"Create a disposable inbox with otpbox, sign up for this app with it, and finish verification with the code you get back."
Every code and link comes from a real delivered email, not a stub - so the test proves the actual signup flow works.
OTP codes and verification links are parsed out automatically. No regex against raw email bodies.
200 requests/month with a key minted in one call - no account, no payment info, no waiting.
create_test_inbox, wait_for_email, get_otp, get_verification_link, create_test_identity, and more - the full loop is agent-callable.
