Slack Integration

The Slack integration provides access to send and manage Slack messages and channels through the Integrate MCP server.

Installation

The Slack integration is included with the SDK:

import { slackIntegration } from "integrate-sdk/server";

Setup

1. Create a Slack OAuth App

1. Go to Slack API Apps
2. Create a new OAuth application
3. Configure your redirect URI
4. Note your Client ID and Client Secret

2. Configure the Integration on Your Server

Add the Slack integration to your server configuration. The integration automatically reads SLACK_CLIENT_ID and SLACK_CLIENT_SECRET from your environment variables:

import { createMCPServer, slackIntegration } from "integrate-sdk/server";

export const { client: serverClient } = createMCPServer({
  apiKey: process.env.INTEGRATE_API_KEY,
  integrations: [
    slackIntegration({
    }),
  ],
});

You can override the environment variables by passing explicit values:

slackIntegration({
  clientId: process.env.CUSTOM_SLACK_ID,
  clientSecret: process.env.CUSTOM_SLACK_SECRET,
});

3. Client-Side Usage

The default client automatically includes all integrations. You can use it directly:

import { client } from "integrate-sdk";

await client.authorize("slack");
const result = await client.slack.sendMessage({
  channel: "value",
});

console.log(result);

If you're using a custom client, add the integration to the integrations array:

import { createMCPClient, slackIntegration } from "integrate-sdk";

const customClient = createMCPClient({
  integrations: [slackIntegration()],
});
