# Announcing Channels for Mastra Agents

Give users access to your agent from Slack, Discord, Telegram, and more.

[Paul Scanlon](/content/authors/paul-scanlon/index.html) · Apr 28, 2026 · 2 min read

Your agent can now respond to mentions and messages on Slack, Discord, Telegram and more. Attach [channel adapters](/content/docs/agents/channels "Visit https://mastra.ai/docs/agents/channels"/index.html) and connect a single agent to multiple platforms without building custom integrations.

Mastra supports all official adapters from Vercel's [Chat SDK](https://chat-sdk.dev/adapters "Visit https://chat-sdk.dev/adapters").

Channels don't change how your agent works. You can still interact, test, iterate and observe it from Studio.

## Get started!

Install adapters for the platforms you want to use (requires `@mastra/core@1.22.0` or later):

```
 1npm install @chat-adapter/slack @chat-adapter/discord
```

Add adapters for each platform. This example connects the agent to both Slack and Discord.

```
 1import { Agent } from "@mastra/core/agent";
 2import { createSlackAdapter } from "@chat-adapter/slack";
 3import { createDiscordAdapter } from "@chat-adapter/discord";
 4
 5export const channelAgent = new Agent({
 6  id: "channel-agent",
 7  name: "Channel Agent",
 8  model: "anthropic/claude-opus-4-6",
 9  instructions: "You are a helpful assistant. Answer questions, help with tasks, and have natural conversations.",
10  channels: {
11    adapters: {
12      slack: createSlackAdapter(),
13      discord: createDiscordAdapter()
14    }
15  }
16});
17
18// Adapters read credentials from environment variables.
19// See the Chat SDK docs for setup:
20// Slack: https://chat-sdk.dev/adapters/slack
21// Discord: https://chat-sdk.dev/adapters/discord
```

Mastra exposes a webhook URL for each adapter on your agent's endpoint. Add it to your platform's event configuration to start receiving messages. For example:

```
 1<your-server-url>/api/agents/channel-agent/channels/slack/webhook
```
