One Fastmail account limit for the MCP in Claude?
I have two separate Fastmail accounts, one personal and one business, and I want Claude to work with both.
The Fastmail MCP connector is set up and working with my personal account. When I try to add it again for the business account, Claude says it is already connected to Fastmail's MCP server.
Fastmail's help page confirms this is a known limit: "Claude does not support adding multiple Fastmail accounts."
Has anyone figured out a way around it? I am interested in anything that works, such as:
- A custom connector using a Fastmail API token instead of the normal sign-in
- Account sharing or delegation so one login exposes both accounts
- A proxy or a community Fastmail MCP server running alongside the official one
Thanks.
