Slack MCP Server

Requires: Node.js · A Slack app with a bot token (xoxb-…) and a team ID

1. 1

   Create a Slack app and bot token

   In the Slack admin, create an app, add the needed bot scopes, install it to the workspace, and copy the Bot User OAuth Token.

2. 2

   Add to your MCP config

   Provide the bot token and team ID as environment variables; optionally scope to specific channel IDs.

           "SLACK_BOT_TOKEN": "xoxb-your-token",
           "SLACK_TEAM_ID": "T0123456"
         }
       }
     }
   }

3. 3

   Restart the host

   Reload the agent so it discovers the Slack tools.

You've been away and a channel has hundreds of unread messages.

What to expect: The agent pulls the real channel history and returns a structured digest, so you catch up without scrolling.

• Name the exact channel and time window to keep the read scoped and fast.
