mcp-server-tempmail is a MCP server that manages ChatTempMail disposable inboxes for signup and OTP testing.
About
mcp-server-tempmail wraps the ChatTempMail API as an MCP server so your agent can provision throwaway addresses and read incoming messages during development and QA-style prototyping. developers validating SaaS onboarding, magic links, or OTP screens use it to close the loop in one chat: trigger signup in a browser or API, then pull the verification email through MCP instead of context-switching to a webmail tab. Configuration is minimal—a required TEMPMAIL_API_KEY and optional TEMPMAIL_BASE_URL defaulting to chat-tempmail.com—and transport is stdio via the published npm package. It is a third-party hosted temp-mail service dependency, not an self-hosted mailserver, so use it for dev and staging-style tests rather than production user mail.
- ChatTempMail API-backed temporary mailbox management over MCP
- Required TEMPMAIL_API_KEY; optional TEMPMAIL_BASE_URL override
- stdio npm package mcp-server-tempmail v1.0.1
- Lets agents create addresses and fetch messages for automated test narratives
- Avoids using personal Gmail during iterative signup experiments

What it does
Create and read disposable inboxes via MCP so you can test signup, OTP, and email flows while prototyping without polluting your real mailbox.
Who is it for?
Best when you're prototyping auth, invites, and transactional email and want agent-driven inbox steps.
Skip if: Production outbound mail, compliance-heavy archival, or teams forbidden from third-party temp-mail services.
What you get
After you add the server with TEMPMAIL_API_KEY, your agent can create temp mailboxes and read messages for automated flow validation.
- Agent-callable tools to create and monitor temporary mailboxes
- Captured verification messages for prototype test scripts
- Faster iterate-test cycles without personal email pollution
By the numbers
- Server version 1.0.1
- 1 required secret: TEMPMAIL_API_KEY
- Default API host documented as https://chat-tempmail.com via TEMPMAIL_BASE_URL
