Connect Zapier MCP to Slack

1

Connect or reconnect Slack in Zapier

Go to your Zapier connections and connect your Slack account.If you already have a Slack connection, reconnect it. Existing connections do not include the MCP permission, so Zapier MCP does not work in Slackbot until you reconnect.
2

Approve the MCP permission

Slack opens Allow the ‘Zapier’ app to access Slack.
  • Under Workspace, select the workspace where you use Slackbot.
  • Under Review app permissions, expand Perform actions in your workspace. Check that this permission is included: Allows “Zapier” to connect to Slack’s AI features through Model Context Protocol (MCP) servers (mcp.zapier.com).
  • Click Allow.
