How Are App Integrations and Credentials Handled in Messiah?
How Messiah connects to Gmail, Google Calendar, Notion, Slack, GitHub, and Linear via Composio with secure token isolation.
Messiah interfaces with third-party productivity applications through standard OAuth 2.0 flows powered by the Composio tooling layer.
What services can Messiah connect to today? - **Google Suite**: Gmail (read messages, compose/send drafts upon approval), Google Calendar (lookup availability, schedule events). - **Workspaces**: Notion (read/write notes and databases), Slack (channel monitoring, draft message dispatch). - **Engineering Tools**: GitHub (issue triage, PR review comments), Linear (ticket updates, task assignment).
Are passwords or API keys stored by Messiah? No. Messiah never handles or stores user passwords. Authentication is conducted via standard OAuth delegation. OAuth access tokens are stored in encrypted vaults and never leaked into model prompting contexts.
