Claude Code How to use Slack with Claude Code
You want Slack inside Claude Code so it can triage a busy Slack workspace, prepare follow-ups from unanswered threads, coordinate the right people, and send a targeted team update — without you copy-pasting between tabs. Here is the whole setup, once.
Create your Slack gateway
The gateway is the thing Claude Code connects to, and it is where you decide which Slack tools an agent may use. You create it once and every client reuses it.
-
Create an Arcade account
Sign up and open the dashboard. The free tier is enough to follow this through.
-
Create an MCP Gateway and select your Slack tools
In the dashboard, create a gateway and pick the Slack tools you want to expose. The gateway is what your client connects to, and it is where tool access is decided.
-
Copy your gateway URL
Every client below needs it.
https://api.arcade.dev/mcp/<YOUR-GATEWAY-SLUG>
Connect the gateway to Claude Code
-
Add the gateway as a remote HTTP MCP server
claude mcp add arcade --transport http "<YOUR_ARCADE_GATEWAY_URL>"
-
Verify it was added
claude mcp get arcade claude mcp list
-
Try it out
Open Claude Code in your project and ask it to use one of your Slack tools.

A mistaken invite or message can reach the wrong people. Pair Slack with Contextual Access policies to require approval before invites or messages, and limit the conversations an agent can access.
