Agent Identity

Listed on mcpservers.org

MCP server that gives an AI agent a throwaway test identity — a real disposable email address and a real UK phone number — so it can sign up for something it's testing and read back the verification email/SMS itself, without a human in the loop.

Bundles two existing services:

• receivemail.dev (source) for the email side.
• sms-florin for the phone/SMS side.

Status: published on npm and the official MCP registry

create_test_email no longer needs any receivemail.dev credential — mailbox creation is public/self-serve (rate-limited: 20/min per IP, 5,000/day total). The only credential needed is your own SMS_FLORIN_API_KEY, for the phone-number tools.

Pairs well with: acp-sandbox

Building or testing an AI shopping agent (ACP/agentic commerce)? acp-sandbox is a hosted mock merchant your agent can complete a full test checkout against — no real store, no real money. Combined with this package, an agent gets a disposable email/phone for the buyer identity and a merchant to actually check out with, entirely test-side.

Pairs well with: otp-watch

Ship your own signup/verification flow? otp-watch uses the same underlying real phone numbers and disposable mailboxes to answer a different question: is your OTP/verification SMS or email actually arriving, and how fast? Point your own cron/CI at it to catch a broken delivery pipeline before your users do.
