# Product Engineering Integrations: Connected Source Systems

> Source systems that feed the Product Engineering domain and what each provides through Spine connectors.

The Product Engineering domain is projected from multiple source systems. Each system connects through a Spine connector that ingests data, normalizes entities, and enables write-back through governed capabilities.

| Source System | Provides                                    | Write-Back                                 |
| ------------- | ------------------------------------------- | ------------------------------------------ |
| Linear        | Issues, epics, sprints, comments            | Issue updates, status changes, assignments |
| Jira          | Issues, epics, versions, sprints            | Issue updates, sprint moves                |
| GitHub        | Pull requests, commits, releases, CI checks | PR merges, release creation, comments      |
| Figma         | Design files, frames, comments              | Status references, comment links           |
| Notion        | Product docs, specs, meeting notes          | Doc references, linked notes               |
| PagerDuty     | Incidents, on-call schedules, escalations   | Incident acknowledgments, reassignments    |
| Sentry        | Error events, issue groups, release health  | Issue status updates                       |
| Datadog       | Metrics, monitors, deployment events        | Alert status references                    |

Each connector uses the MCP protocol for tool integration. Authorization is scoped per workspace and role.
