Guides

GetCourier gives an AI agent a real email inbox in one HTTP call, with no signup and no API key, and hands back the verification code or magic link when the mail arrives. These guides answer one question each.

• Give your AI agent an email inbox in one call — POST /alias with no body, no signup and no API key returns a real address, a read_token and a 72-hour inbox in about 15 ms.
• Receive a verification code or magic link in an AI agent — Long-poll /v1/sandbox/inboxes/{alias}/wait, or call the MCP wait_for_code tool, and get the code or link the moment the mail lands.
• Use GetCourier as a hosted MCP server — Add https://getcourier.dev/mcp to Claude Code, Cursor, Claude Desktop, the Grok CLI or the xAI API. No install, no key.
• Read untrusted email safely in an LLM agent — Every message arrives marked untrusted, with SPF/DKIM/DMARC results, and hidden or zero-width text stripped before your model sees it.
