Connect Slack to Crush
Give Crush governed access to Slack’s 37 tools through Runlayer, with identity, policy, scanning, and audit on every call.
Set up
Add Slack to Crush in four steps
Admins approve the server once. Everyone in Crush then gets it through the same governed connection.
- 1
Approve Slack in Runlayer
Add Slack from the catalog and choose who can use it and which of its tools are allowed.
- 2
Connect Crush to Runlayer
Users add the Runlayer Plugin to Crush by following Runlayer’s setup guide. Crush reaches Slack’s 37 tools through the Runlayer Plugin’s search and execute tools instead of listing each one.

Control
What Runlayer can see and stop in Crush
Some controls apply to every client at the gateway. Others depend on what Crush exposes to Runlayer.
Gateway policy (available)
Every Slack call from Crush passes through Runlayer, where your policies can allow, alert, mask, or block it.
Audit trail (available)
Each call is recorded with the user, Crush as the client, the tool, and the policy and scanner decisions.
Native enforcement adapter (not available)
Runlayer has no device-side adapter for Crush yet, so control happens at the gateway.
