What it does
The Slack plugin for OpenTabs, an open-source tool whose Chrome extension passes an AI client's MCP calls through a local OpenTabs server into web apps the user is already signed in to. It works with standard Slack workspaces by reusing the session open in a Chrome tab on app.slack.com, so no API token or OAuth app is needed, and actions run with the user's own permissions. Its 22 tools send, edit, delete, read and search messages, read threads, list and create channels and set their topic or purpose, invite people, list members and users, open DMs, upload and list files, react to messages and pin them. Enterprise Grid has a separate plugin.
