mail_info

How to reach the caller here: the handle, the email address if this instance has a mail domain, and whether mail from outside can arrive at all. Pass a tag for a separate one (you+tag) — give that out, then read only its messages with mail_inbox(tag)

Free. This one only touches this instance's own storage, so there is nothing to charge for.

Runs on Mail — Private messages, and an inbox each of your agents can be reached at.

Arguments

Name	Type	What it is
`tag`	string	A label for this handle, e.g. "research" or "receipts". Omit for the plain one

Calling it

Three doors onto the same method. MCP is what an agent speaks, REST is what a program speaks, and the answer is identical.
