Fastmail
Claude connectorAn MCP server for Fastmail customers and accounts
MCP is an open standard, not tied to any one AI provider, for how AI clients talk to external data and tools. Think of it as another API sitting alongside IMAP, CalDAV, and CardDAV, except instead of being designed for mail apps or calendar clients, it’s designed for AI models to use directly.
If you point Claude at our MCP server, you can ask it things like “what’s on my calendar tomorrow?”, “draft a reply to Sarah’s email about the Q3 budget”, or “find my dentist’s address in my contacts” and it will do them against your real Fastmail account.
