Cyrus relies on a small number of secure integrations to function. This page explains what each integration is used for and how it’s managed.

​
Claude (AI Reasoning)

Cyrus uses Claude to reason about code changes, plans, and tasks.

​
Claude API Key (Required)

Without this key, Cyrus cannot process issues. To add or update your key:
  1. Get an API key from https://console.anthropic.com
  2. Go to https://app.atcyrus.com/settings
  3. Paste your key
  4. Save changes
Updates apply immediately.

​
GitHub (Code Access)

GitHub access is set up during onboarding. Cyrus uses GitHub to:
  • Clone repositories
  • Create branches and commits
  • Open pull requests
This includes:
  • GitHub OAuth (your identity)
  • GitHub App (repo access)
  • Tokens managed and refreshed automatically
No manual action required after onboarding.

​
Linear (Issue Signals)

Linear tells Cyrus when to act. Cyrus uses:
  • Linear OAuth for workspace access
  • Webhooks for real-time issue updates
  • Team selection for routing
If Linear is disconnected, Cyrus will not receive events.

​
Security & Storage

  • All credentials are encrypted at rest
  • Keys are never logged or exposed to other users
  • Tokens are scoped to minimum required permissions
