Qwen Code (Alibaba's open-source terminal coding agent) supports remote MCP servers the same way Gemini CLI does - add OTPBox once, use it from any Qwen Code session.
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 ~/.qwen/settings.json, or via the CLI:
qwen mcp add --scope user --transport http otpbox https://otpbox.io/mcp
# or in settings.json directly:
{
"mcpServers": {
"otpbox": {
"httpUrl": "https://otpbox.io/mcp",
"headers": { "Authorization": "Bearer <your-otpbox-key>" }
}
}
}
httpUrl for the streamable-HTTP transport, matching Gemini CLI's convention (it began as a fork of it).Once connected, Qwen Code can call OTPBox's 13 MCP tools directly. For example:
"Use otpbox to create a test inbox, sign up for this app with it, and get me the OTP code."
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.
