MCPBundles publishes this directory for MCP discovery. Except where we host or operate an offering, third-party services run under their own terms. Product and company names on this page are used in a descriptive, identifying way (including under nominative fair use where applicable); they remain the property of their owners. Nothing here grants you rights in those marks, and nothing here is an offer to sell a third party's services. Terms

What is Fastmail MCP?
It lets AI agents in Cursor, Claude, or ChatGPT work with your Fastmail mailbox — search and read mail, triage unread messages, send replies, and manage masked addresses — after you connect in MCPBundles.
Who is this for?
Operators and assistants who live in email and want inbox summaries, thread catch-ups, and send workflows from chat instead of copying subjects between tabs.
Can an agent delete my mail?
Agents can move, mark read, send, and manage drafts when you ask. Permanent deletion only happens when you explicitly request it.
