Provision mailboxes on verified domains or a shared myagent.mx address, with clean JSON output that strips signatures and quotes.
Send over HTTP or SMTP using the same mailbox credential as a Bearer token and SMTP password, with Idempotency-Key retries and attachment support.
Bind keys to providers, delivery groups, weights, and quota windows so traffic stays inside the boundaries you set.

面向团队的协作式收件箱与邮件管理
免费 / 开源Exceptional open-source gateway for LLM provider routing, but lacks Composio's extensive library of SaaS tool integrations and auth.
专项更强Robust TypeScript framework for agent workflows and tools, but requires writing custom integration code instead of pre-built connectors.
面向编码智能体的 Fast Apply 与智能体调优推理
专项更强Flexible Python agent framework with built-in tools, but less focused on acting as a standalone universal integration middleware.
