LobsterMail

Say your agent needs to sign up for a service and confirm the address from a verification email. With LobsterMail, the agent creates its own inbox in seconds, receives the message and reads it, with no person filling in a signup form first.

LobsterMail is an email infrastructure tool for AI agents that lets them provision inboxes, send mail and receive mail on their own.

There are no human signups, no API keys and no complicated configuration to deal with.

Developers get a JavaScript/TypeScript SDK and an MCP server.

It is made for people building agents with frameworks such as OpenClaw, LangChain, CrewAI and AutoGen.

Incoming email is a real risk for an autonomous agent, since a message can carry hidden instructions.

LobsterMail has built-in protection against prompt injection and scans incoming emails across multiple categories before the agent acts on them.

That is a sensible default if your agent reads mail from strangers.

It fits developers who want an AI email assistant layer for their agents rather than a mailbox built for humans.
