>log in to commentHey everyone 👋 I'm Pratham, the maker of Roster. I work across several client Slack workspaces and kept losing track, so I built one MCP connector that keeps each client separate. Slack is live, Gmail and Teams are next. It's in beta, so I'd love to hear what's confusing or broken.
Roster is a remote MCP server that connects your clients' Slack workspaces to Claude (or any MCP client), grouped by client. Add a client, connect as many of its workspaces as you need with Add to Slack, then add one connector URL in Claude. Every tool call takes a required client argument, so one question never reads two clients' data. Read-only user scopes, tokens encrypted with AES-256-GCM, no message content stored or logged, per-workspace channel allow-lists, DMs filtered out. Claude signs in with OAuth 2.1. Slack works today; Gmail and Microsoft Teams are next. In beta and looking for testers.
