Slack MCP connector

Slack is a cloud-based team communication platform for workplace collaboration and messaging. The Slack MCP connector allows AI agents to send messages to channels and users, create and manage channels, and set reminders for team members. It also supports searching message history, updating or deleting messages, creating ephemeral messages, and generating message permalinks for sharing specific conversations.

Authentication type

• OAuth 2.0 Authorization Code - Requires a one-time user login to authorize the agent to access the service on their behalf.

• Send urgent alerts to specific Slack channels when critical business events occur
• Archive completed project channels to maintain organized workspace structure
• Retrieve message history from channels to audit communication and compliance records
• Invite team members to channels automatically based on project assignments
• Post formatted updates to channels without manual notifications interrupting users
