Feature request: Support multiple Slack workspaces in the built-in Slack connector

[nath-maker]

Feature Request

The built-in Slack MCP connector currently supports only one workspace per Claude account. There is no way to add a second workspace through the UI or configuration.

Use Case

Many professionals work across multiple Slack workspaces -- for example, a consultant with their own company workspace and a client workspace, or a founder who advises other companies. Today, connecting workspace #1 is one click. Connecting workspace #2 requires setting up a self-hosted MCP server from scratch: downloading a third-party binary, creating a Slack app manually at api.slack.com, configuring seven OAuth scopes, writing MCP JSON config with the correct CLI flags, and restarting Claude Code.

Request

Allow users to authorize multiple Slack workspaces through the same built-in connector that makes the first workspace so easy. Even supporting two would cover the majority of multi-workspace users.

Not a dupe. This is a distinct issue.

I have a work slack and a home slack, and I'd like my assistant to be able to aggregate information across both when needed.

[nath-maker]

Yes. I have a fairly similar situation. In this case 1 Pro Max x20 personal claude and slack, and 1 Claude and 1 Slack from my company. Even if I could just have each communicate with the corresponding slack with an easier way to sign into my different versions of Claude, it would be amazing.

+1. Many companies have multiple slack workspaces and then add to them many attached customer/partner workspaces!
