myagentinbox gives an AI agent somewhere to receive email. The agent creates a temporary address, uses it for a signup or a verification step, reads whatever arrives, and moves on. Everything is deleted 24 hours after the inbox is created.
It exists because most agent tasks need an email address for about ninety seconds — long enough for a confirmation code or a magic link — and the alternatives are worse. A real mailbox has to be managed and cleaned up, and it collides with itself the moment two runs happen in parallel. A stubbed one tells you nothing about whether the actual email would have arrived.
It is built for people writing agents that hit an email wall: account verification, magic-link logins, reading notifications, and end-to-end tests of signup flows. Connect over MCP or the REST API. There is no signup and no API key.
