Slack MCP Server

Slack's hosted MCP server uses confidential OAuth tied to a registered Slack app and user-token scopes, letting approved clients search messages and files, read channel and thread history, send messages, manage canvases and lists and upload files.

What it does

  • Search messages, files, users and channels
  • Read channel and thread history
  • Send and schedule messages, add reactions
  • Create and update canvases and lists, upload files

Best for

Agencies coordinating client work in Slack who use Claude, Cursor or Perplexity.

Watch out for

Only directory-published or internal apps may use MCP, workspace admins must approve clients, and the tool surface depends on granted scopes.
