Fastmail Tools

What problem does it solve?

Fastmail does not provide a native MCP server, making it hard for AI assistants to read, search, and manage your emails, contacts, and calendar without manual copy/paste or custom integration.

Core Features & Use Cases

• Token-efficient Fastmail actions: Executes Fastmail operations through the local fastmail CLI and returns compact, LLM-optimized text for faster, cheaper reasoning.
• Inbox reading and retrieval: Fetches recent emails, full email bodies in markdown, and entire conversation threads.
• Search, organization, and bulk triage: Supports text search with filters, plus marking read/unread, flagging/unflagging, deleting, and moving emails.
• Account utilities: Provides mailboxes, stats, identities, and incremental inbox updates for synchronization use cases.

Quick Start

Ask your AI to “use fastmail_inbox to list my 10 most recent emails, then read the top email with fastmail_get_email using its ID.”
