api.temp-mail.io

Temp Mail gives Claude its own disposable inboxes, so an agent can complete any flow that sends an email without involving your real mailbox.

Create a temporary address on demand, check it for incoming mail, and read the message — including the verification code, magic link, or attachment it carries. Addresses and their messages can be deleted the moment you're done.

Typical uses:

• Sign up for a service end to end and confirm the account, without a human pasting the code
• Exercise your own signup, password-reset, or email-verification flows from an agent or a CI run
• Inspect exactly what an email looks like on arrival, including raw RFC-2822 source and headers
• Fetch a PDF, CSV, or image attachment that was emailed to you and work with it directly

Nine tools: list_domains, create_email, delete_email, list_messages, get_message, get_message_source, delete_message, get_attachment, get_rate_limit. Six only read data; create_email adds an address; delete_email and delete_message remove data and are annotated as destructive.

Requires temp-mail.io account. You connect over OAuth 2.0 — Claude never sees your password, and you can revoke access at any time from your account settings. Tool calls draw on the same monthly request quota as the temp-mail.io REST API, and get_rate_limit reports what's left at any point.
