Overview
What is LobsterMail?
LobsterMail is an email infrastructure specifically built for AI agents, allowing them to provision their own email inboxes in seconds without human intervention. It eliminates the need for human signups, API keys, or complex configurations by offering a JavaScript/TypeScript SDK and an MCP server. The platform focuses on security, featuring built-in protection against prompt injection attacks by scanning incoming emails across multiple categories. It enables agents to send and receive emails autonomously, making it ideal for developers building with frameworks like OpenClaw, LangChain, CrewAI, and AutoGen.
