Mailbox MCP is an MCP server entry in ChatHome Skills, sourced from Official MCP Registry and scored 100/100. As a Model Context Protocol server, it exposes tools that MCP-compatible LLM clients such as Claude, Cursor, and Copilot can call directly, extending an agent's reach beyond its built-in capabilities. ChatHome Skills discovered this entry through its daily ingest of official registries and GitHub discovery queries, and re-verifies repository facts, freshness signals, and install metadata on every run. The quality score weighs official-registry presence, a working install command, license clarity, GitHub star trajectory, and repository freshness — the full formula is on the Sources page. The install command above is ready to copy. Review the last-pushed date and repository status before adding Mailbox MCP to a production agent workflow; the snapshot facts below are point-in-time values from the most recent ingest.

"summary": "Mailbox MCP connects an assistant to a real mailbox over IMAP and SMTP, so it can read, write, file and search mail as the owner would. The mailbox has to look untouched afterwards in Outlook or webmail, and that rule decides the implementation: reading never marks a message as read, a send files exactly one copy in Sent, a delete moves to Trash, a draft is saved where another client can edit it, a move keeps flags and the internal date, and folders resolve by their special-use flag instead of by name. It archives and reports spam by role rather than by folder name, so on Gmail archiving drops the inbox label. It reads attachments: a PDF, a Word file or a spreadsheet as text, a photo as a picture. After a send, check_bounces says whether an address failed for good or is being retried, and check_receipts whether it was opened, even when nothing came back. catch_up, waiting_on and owed_replies answer in one call each what came in, what nobody has answered and who is waiting on a reply. A diary connected separately adds calendar tools: reading and searching events, free/busy, booking and moving your own time, inviting, cancelling, answering or proposing another time, and the out-of-office reply. A CardDAV address book connected to an IMAP mailbox, also separately, lets find_contact read the book beside the mailbox's own history, and adds read_contact to open one card. No contact is stored on the server.",
