An MCP server that exposes a local notmuch email database to an LLM client such as Claude. It is read-first: searching, reading, and understanding mail is always available; writing anything (drafts, tags, exported files) requires an explicit opt-in flag and is confined to clearly bounded locations.

Enables MCP clients to read and search Proton Mail and create draft-only emails with attachments through the local Proton Mail Bridge, while requiring out-of-band human approval before a draft can be committed.

Enables AI assistants to search and read institutional IMAP mailboxes, download attachments, mark messages read or unread, move them between folders, and save drafts, all safely by UID. Runs locally over stdio or as a remote HTTP/SSE endpoint secured by a bearer token for clients like ChatGPT and n8n.

Enables MCP clients to search, read, and manage a self-hosted mailbox over JMAP, including attachments with OCR, sending, drafts, and contacts.

Gives an AI assistant read- and draft-only access to a single personal Microsoft mailbox, letting it search, list and read mail, browse folders, save attachments to a jailed directory, and create new or reply drafts.
