+# MCP servers
+
+## Repository intent
+
+This repository defines MCP servers and implementation guides that support
+enterprise identity operations across multiple systems.
+
+- Identity: provides a production-oriented read path for AD user and group data,
+	with adapters, server wiring, and tests.
+- Workday: defines the Workday-to-AD identity sync implementation approach,
+	phased delivery, and operational controls.
+- Intune: captures deployment prerequisites and planning artifacts for endpoint
+	management integrations.
+
+## Current workflow intent
+
+The active workflow is focused on delivering a controlled Workday-to-AD sync
+capability that:
+
+- Uses Workday as source of truth for worker lifecycle state.
+- Uses Identity MCP as the downstream enforcement and validation interface.
+- Starts read-only, then introduces approval-gated remediation actions.
+- Tracks measurable outcomes, including drift reduction and provisioning speed.
+
+## Progress snapshot (2026-04-03)
+
+### Completed
+
+- Workday execution backlog created: [Workday/workday-ad-identity-sync-next-steps.md](Workday/workday-ad-identity-sync-next-steps.md).
+- Sprint-ready board created: [Workday/workday-ad-identity-sync-sprint-board.md](Workday/workday-ad-identity-sync-sprint-board.md).
+- Identity MCP baseline is in place with code and tests under [Identity](Identity/).
+
+### In progress
+
+- Converting strategy into sprint-trackable work items (WIS-001 to WIS-030).
+- Preparing dependency closure sequence for auth, non-prod access, and data
+	contract controls.
+
+### Next milestones
+
+- Q2 milestone 1: close blockers and validate non-prod read-only path.
+- Q2 milestone 2: implement core Workday MCP tools and mismatch detection.
+- Q2 milestone 3: enable daily sync checks with ticketed approval workflow.
+- Q3 milestones: drift reporting, production rollout, and >=30% MTTP
+	reduction versus Q1 baseline.
