Great work on excel-mcp-server. \n\nOne concern I had when deploying it: once Claude Desktop users connect to your server, can you tell *which specific user* triggered each tool call? For example, if someone writes to a spreadsheet file they shouldn't have access to, do you have any way to identify them?\n\nI built a lightweight identity middleware that adds caller verification to MCP servers (like OAuth for MCP tools). Happy to help wire it up if you think it'd be useful for your users. Takes…",
