How to use Slack with Cursor

You want Slack inside Cursor 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 Cursor connects to, and it is where you decide which Slack tools an agent may use. You create it once and every client reuses it.

  1. Create an Arcade account

    Sign up and open the dashboard. The free tier is enough to follow this through.

  2. 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.

  3. Copy your gateway URL

    Every client below needs it.

    https://api.arcade.dev/mcp/<YOUR-GATEWAY-SLUG>

Create a Slack gateway Opens the gateway builder in your Arcade dashboard.

Connect the gateway to Cursor

Heads up

Cursor does not refresh MCP OAuth tokens automatically. For a persistent connection, set Authorization to “Arcade Headers” on the gateway in the dashboard.

  1. Open MCP settings

    Command Palette (⌘⇧P / Ctrl+Shift+P) → Open MCP Settings, then click “New MCP Server”.

  2. Add the gateway to mcpServers

    {
      "mcpServers": {
        "mcp-arcade": {
          "url": "https://api.arcade.dev/mcp/<YOUR-GATEWAY-SLUG>"
        }
      }
    }

  3. Try it out

    Ask Cursor to use one of your Slack tools.

Get started with these Slack prompts

Cursor can now act on your Slack account. Click a prompt to copy it.

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.
