Does Slack MCP Servers Support Authentication for Multiple Accounts?

This topic was automatically generated from Slack. You can find the original thread here.

I have multiple Slack accounts that I wanted to authenticate in the Slack MCP servers, but it seems like it only supports one authentication.

That’s true it only supports 1 for the time being. The API support >1, so that would be feasible to support. Are you using the hosted URLs for yourself or deploying the server to your app for your users?

I am using it for myself e.g. Claude, Cursor, etc.

Yea there’s a little bit of complexity there but we’re working through the backlog now, so that’s good feedback. We’ve found the 1 account per app setup addresses the vast majority of use cases but >1 is on the radar.

As in you want your agents to orchestrate across multiple Slack workspaces?

For example: cursor I want to dm me in my person slack; augment may be both personal and work ,doubt this is possible; Claude slack me at work.

I could probably figure a way to just use the one slack

So just checking not a p0

Yea, the use case generally makes a lot of sense and I can see a pathway for supporting it — like I said, the Connect API supports it, our MCP model doesn’t currently, but it makes sense that we will.
