Temp Mail Agency vs Temp-Mail.io
Temp-Mail.io is a long-running temporary email service that recently added an MCP server — but put it behind its Premium subscription. Temp Mail Agency's MCP server is free for everyone: one Google sign-in for a key, 100 emails/day, no subscription. If you are connecting an AI agent to disposable email, that difference decides it.
