zerodrop-dev/zerodrop-mcp

zerodrop-mcp is an MCP server that gives AI agents their own disposable email inboxes, so the agent can sign up for services on its own without a human stepping in to fetch a verification code. It works with Claude, Claude Code, Claude Desktop, Cursor, and any other tool that speaks the Model Context Protocol. The problem it solves is simple but common: an AI agent signs up for a service, that service sends a one time verification code or a magic link by email, and the agent has no inbox to read that email from, so it gets stuck. With this tool, the agent can generate a throwaway email address instantly, use it to fill out a signup form, then wait for the confirmation email to arrive. When it does, the tool automatically pulls out the one time code or magic link for the agent, so the agent never has to parse raw email content itself. Setting it up is meant to be simple: there is no Docker container to run, no email server to configure, and no account or API key required for the free tier. Installing it is just a single command or a short config file entry, depending on which AI tool you use. Behind the scenes, incoming emails to a generated inbox are intercepted by a Cloudflare edge worker that is part of the same project, and the codes or links are pulled out right there before the agent ever reads the message. On the free tier, inboxes are automatically deleted after thirty minutes. An optional paid workspace key unlocks extra features and lets you self host your own instance instead of using the shared one. This tool is aimed at developers who use AI coding agents to test signup and login flows end to end, automate quality assurance testing that involves email verification steps, or let an agent independently verify that its own app's email flow actually works. It is released under the MIT license.
