Verify which account a Gmail MCP connector is authenticated as

A claude.ai Gmail connector can be signed in to a different person's account than the current user's. In this session, search results addressed another person by name ('Hi <other name>'), which was the giveaway. Before treating results as the user's mail, check greetings, recipients and the authuser in returned URLs. On a mismatch, stop reading that mailbox and use the user's own inbox instead, e.g. webmail through browser automation.
