Slack

Slack's official hosted MCP server for enterprise search and collaboration workflows.

Connection

A workspace administrator configures an eligible Slack app once. Each person then connects their own Slack account through Aprés.

Setup requirements

An internal Slack app or a Slack Marketplace-published app; unlisted distributed apps cannot use Slack MCP
Workspace administrator approval for the Slack app
The registered Slack app's client ID and client secret
The listed scopes configured as User Token Scopes under OAuth & Permissions in the Slack app
The exact redirect URL https://gateway.mcp.computer/callback registered under OAuth & Permissions
If the Slack app restricts IP addresses, its allowlist must permit requests from Aprés
