"Raspberry Pi" matching MCP servers:

Provider-agnostic email MCP server that connects any IMAP mailbox to AI assistants, enabling email management through natural language.

Create disposable email inboxes, extract OTP codes in 15 languages, and receive webhooks — all from your AI agent. One call: create inbox → wait for email → get the verification code. Supports 7 domains, email forwarding, and HMAC-signed webhooks with OTP included in payload. Free tier available.
