Enable PAT-less authentication to the Harness API (either direct integration or through MCP) that supports On-Behalf-Of (OBO) so downstream API calls preserve the end-user identity, entitlements, and audit context. The current service account approach is not acceptable due to permissioning, auditability, and operational risk. Problem: Today, accessing Harness programmatically typically relies on: Personal Access Tokens (PATs), which introduce token lifecycle/rotation risks and are not ideal for enterprise controls; or Service accounts, which collapse user context and can lead to over-privilege, weaker auditing, and governance friction. We need a solution where: Calls to Harness are performed without PATs, and Each request is executed in the context of the initiating user (OBO), so authorization reflects that user’s permissions and is audit-friendly. Goals Provide a PAT-less authentication mechanism for Harness API calls Support OBO / delegated authorization so Harness actions reflect the real user Improve audit trail fidelity (who did what) and reduce over-privileged service accounts Enable integration via MCP (or equivalent broker) with standardized auth propagation
