GrabMail

Temp mail for humans, CI pipelines and AI agents: pick any address, receive the code, read it in the browser or over HTTP. Free, no account needed. Three JSON endpoints (mailbox, message, attachment), OpenAPI 3.1, llms.txt and a streamable-HTTP MCP server at https://grabmail.io/mcp. Public domains are free and keyless; your own domain works with one MX record.
