What fixture.email — Email Testing for Agents needs before it works

A sign-in. The server refused to list its tools to an anonymous client and answered with an authentication challenge, which is how an MCP server protected by OAuth behaves. Add it with one of the setups below; the first connection opens a login for your fixture.email account, and the tools appear once you have approved it.
