概要

What is Mailsink?

Mailsink is a Model Context Protocol (MCP) server that provides programmatic temporary email inboxes for AI agents and test automation. It gives agents eight typed tools for provisioning disposable addresses, waiting on signup emails, extracting OTP codes and magic links, and cleaning up after themselves. Works with Claude Code, Claude Desktop, Cursor, Windsurf, and any MCP-aware client.

How to use Mailsink?

Install globally via npm install -g @mailsink/mcp or run with npx -y @mailsink/mcp. Requires a free API key from mailsink.dev (exported as MAILSINK_API_KEY). Configure the client's mcpServers section with command npx and args ["-y", "@mailsink/mcp"] plus MAILSINK_API_KEY in env. Restart the client to see eight tools like create_inbox, wait_for_email, get_verification_code, etc.
