### Description (declared)

# unr-mail-mcp: a multi-mailbox email MCP server for Obot

You will end up with one Obot MCP server that gives an agent **a clear picture of all incoming and
outgoing mail across your mailboxes** (`overview`), **two tools per mailbox** (`<address>_read`,
`<address>_send`) and a few shared tools (`reply`, `mark`, `move`, …), usable from Obot chat, agents,
and any MCP client.

An agent that reads mail reads text written by strangers. This server is built for that: it
validates everything an agent passes in, cleans everything that comes out of a mailbox, and puts hard
limits on what can leave. Read [Security model](#step-6--security-model) before you give it to an agent.

Time: ~15 minutes. Needs: Python 3.11+, [`uv`](https://docs.astral.sh/uv/), an Obot instance
where you can add MCP servers (admin), and mailbox credentials.

## Step 0 — The tools you get

| Tool | What it does | Needs approval? |
|---|---|---|
| `overview` | **Start here.** For every mailbox (or the ones you name): unread count, newest incoming mail (INBOX), newest outgoing mail (Sent), and the *conversations* linking them, each marked with who wrote last and whether it is still awaiting a reply | no (read-only) |
| `<slug>_read` | List a folder (`unread_only`, `since`, `search` in text/from/to/subject) or open one message by `uid` | no (read-only) |
| `list_accounts`, `list_folders` | Mailboxes with what an agent may do with each; folders with their role (inbox, sent, drafts, trash, …) | no (read-only) |
| `reply` | Answers a message **by saving a draft** with correct threading; a person reviews and sends it | no |
| `save_draft` | Saves a new message to Drafts | no |
| `mark` | Read/unread, flagged/unflagged | optional |
| `<slug>_send` | Sends mail **immediately and irreversibly** | **yes** |
| `send_reply` | Sends a reply immediately; the first call only returns the recipients, a second call with `confirm_recipients` sends | **yes** |
| `move` | Moves messages to another folder (archive, tr…
