How does Fastmail connect to Meteor?

With the Fastmail ready connector, your Met uses the official Fastmail MCP server on your account, authorized once with OAuth and your normal Fastmail password. It can search and read emails and threads, write drafts, organize the mailbox, find and update contacts, and check, create or change events in your calendars, as well as answer invitations. When you authorize, you choose the access level: read only, write or send. The Fastmail MCP does not give access to attachments, and archiving or deleting emails, contacts and events starts turned off.

What it automates

What a Meteor Met does with Fastmail

Book a visit from the chat

A customer asks for an appointment on WhatsApp. Your Met checks that day's events in the calendar you chose, creates the event and leaves the confirmation email as a draft.

Find a customer's details

When someone on your team asks about a customer, the Met looks them up in your Fastmail contacts and replies with what is saved, or updates their phone if it changed.

Sum up what reached the inbox

The Met searches the emails from the last few days, reads the threads and gives your team a list of what is pending, without opening the mailbox.

Tidy up the mailbox

With write access authorized, the Met moves the emails from a supplier or a customer to their folder so the mailbox stays up to date.

The limits

What the Fastmail integration does NOT do

We would rather say it here than have you find out during rollout.

It does not read attachments. Fastmail says its MCP does not give access to email attachments for now.
It does not promise to send emails. The published tool list has no tool named for sending: the Met leaves drafts for your team to review and send.
It does not do more than you authorized. When you connect, you choose read only, write or send, and the Met stays within that level.
It does not ask you for confirmation in the chat before writing. The admin chooses in Connections which actions stay on; archiving and deleting start turned off.
It does not pay your Fastmail plan. Usage runs on your account; Meteor does not resell Fastmail.
