Tools & Integrations
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.
Go to Plain AI → Sidekick → Integrations
Find the integration you want and click Connect
Complete the authentication flow
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.

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

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.
