Challenge Title: One MCP Session. Multiple Gmail Accounts

Description Paragraph 1: NITSAN AI built Multi-Gmail-MCP to manage multiple Gmail accounts from a single MCP session. Instead of running one server per account, each Gmail account is authenticated once and managed through alias-based account isolation. The project is open source and currently used across NITSAN's internal multi-brand operations.

Challenge Title: Challenge

Description Paragraph 1: NITSAN manages multiple Gmail accounts across its brands. Existing Gmail MCP implementations typically bind one authenticated session to one Gmail account, requiring multiple server instances, repeated authentication, and manual account switching. This made AI-assisted email workflows harder to manage as the number of accounts increased.
