The Linear integration syncs issues from your selected teams into Mains’s entity store. Linear issues — with their identifiers like ABC-123 — become searchable locally and available as context in AI chat.

​
Authentication

Linear uses an API key for authentication. You can generate a personal API key from your Linear account settings. The key is stored encrypted in the local database.
Mains uses the @linear/sdk package to communicate with the Linear API, providing typed access to issues, teams, labels, and other resources.

​
