Slack Agent Demo Light

​
Overview

Welcome to Magma! 🌋 This template will help you create:
  • An AI agent hosted on Magma
  • A Slack app connected to your agent
  • Interactive chat with your agent right in your Slack workspace
Prerequisites:
  • A Slack workspace where you have admin permissions

​
Getting Started

First, we need the Magma CLI to clone the Slack DM template, and save it to your Magma account.
1

Install the CLI

npm install -g @pompeii-labs/cli
2

Login to Magma

magma login
3

Use the Slack DM Template

The magma init command is how you create a new Magma agent project. If you provide the -t flag, it will use the template you specify. Here, we’re using the slack-dm template.
magma init -t slack-dm <agent-name>
4

Save the Agent

After you’ve created your agent, cd into the project directory and run:
magma save
5

Update the Slack manifest.json

Running magma save will return your AGENT_ID which you will need to update the settings.event_subscriptions.request_url. The manifest.json file can be found inside of your slack agent container.

​
Slack App Setup

​
Manifest Configuration

The manifest.json file in your project root contains all the necessary Slack app configurations. You only need to update two values.

​
Creating Your Slack App

1

Create New App

  1. Go to https://api.slack.com/apps
  2. Click “Create an app”
  3. Select “From a manifest”
2

Select Workspace

Choose the workspace where you want to install the app
3

Upload Manifest

Replace the default manifest with the contents of your manifest.json
4

Review and Create

Click “Create” to finalize your app

​
Installing the App

1

Install to Workspace

  1. Navigate to “OAuth & Permissions”
  2. Click “Install to Workspace”
  3. Approve the requested permissions
2

Get Bot Token

After installation, copy the Bot User OAuth Token
3

Set Environment Variable

Add the token to your .env file:
SLACK_BOT_TOKEN=xoxb-your-token-here

​
Deployment

magma deploy
This will:
  • Deploy your agent to Magma’s infrastructure
  • Set up the webhook endpoint for Slack events
  • Enable real-time communication between Slack and your agent
After deployment, go to your Slack App settings > Event Subscriptions and verify that the Request URL shows as “Verified”. If it’s not verified, double-check your AGENT_ID in the manifest.json.

​
Testing Your Agent

Use cmd+t (Mac) or ctrl+t (Windows) to quickly search for your bot in Slack!
  1. Open your Slack workspace
  2. Search for your agent by name
  3. Start a DM conversation
  4. Send a message to test the connection
If you run into any issues, use magma logs to view your agent’s logs and debug the problem.
