# Tools & integrations

> Connect your tools to Sidekick and get context from Linear, GitHub, Datadog, Sentry, LaunchDarkly, Attio, HubSpot, Notion, and more, without leaving Plain.

Sidekick treats Plain's own data as home base and reaches outward through every connected integration. Instead of switching tabs to check Linear, GitHub, Datadog, or Notion, you ask Sidekick and it surfaces what's relevant, directly inside a conversation.

The more tools you connect, the more Sidekick can do. This article covers the catalog and how to connect it. For what Sidekick can *do* in these tools, and how approvals work, see **Actions and approvals.**

## How to connect an integration

You need to be a workspace **Admin** or **Owner** to connect integrations.

1. Go to **Plain AI → Sidekick → Integrations**

2. Find the integration you want and click **Connect**

3. Complete the authentication flow

4. Once connected, the integration is available to everyone in your workspace immediately

To disconnect, return to the same page and click **Disconnect**.

## How integrations work in a session

You don't configure anything per session. When you open Sidekick, it discovers which integrations your workspace has connected and uses them as needed. As it works, you can see its tool calls on screen in real time, so you always know what it looked up and why.

## Supported integrations

Every tool is opt-in and connected through **Sidekick → Integrations**. The catalog spans five categories, plus Slack, GitHub, and custom MCP servers.

This Slack integration lets Sidekick look up Slack messages while you work in Plain.
It's separate from Sidekick in Slack, which lets your team @mention Plain inside a Slack channel.
You can enable each independently.

### Custom MCP servers

You can connect any internal tool to Sidekick through a custom MCP server, plugging your own systems into Sidekick's reach.
