Slack MCP + Claude

Step 1. Create a Slack App and Get Required Credentials

First, you need to create a Slack app and get the necessary credentials:

• Go to the Slack API website and sign in to your Slack account
• Click "Create New App" and choose "From scratch"
• Name your app (e.g., "Claude MCP Integration") and select your workspace
• Once created, navigate to "OAuth & Permissions" in the sidebar
• Under "Bot Token Scopes", add the following permissions:

channels:history
channels:read
chat:write
reactions:write
users:read

• Scroll up and click "Install to Workspace"
• After installation, you'll receive a Bot User OAuth Token starting with "xoxb-"

Step 2. Get Your Team ID and Channel ID

• In your Slack workspace, right-click on your workspace name in the top-left and select "Copy link"
• The link will look like https://app.slack.com/client/T01ABCDEFG/... - the T01ABCDEFG part is your Team ID
• To get a Channel ID, right-click on a channel and select "Copy link"
• The link will look like https://your-workspace.slack.com/archives/C01ABCDEFG - the C01ABCDEFG part is your Channel ID

By now, you must have the following details with you.

provider: slack
team_id: XXX
channel_id: XXX
Slack token: xoxb-1XXX
