Executive Summary
- Tier 1 — all requirements met; the C# MCP SDK achieves the highest tier classification
- Server conformance: 100% (30/30 scenarios passing across both
2025-06-18 and 2025-11-25 spec versions)
- Client conformance: 100% of date-versioned scenarios (23/23); 3
extension-spec scenarios fail but are informational only (not counted toward tier)
- Issue triage: 100% compliance rate across 113 issues, median triage time 0 hours
- P0 status: 0 open P0 issues; no P0 SLA violations
- Stable release: v1.2.0 (non-prerelease, >= 1.0.0)
- Spec tracking: 0-day gap between latest spec release (2025-11-25) and SDK release
- Documentation coverage: 48/48 non-experimental features documented with prose and code examples
- No blockers for Tier 1; SDK is fully compliant on all 8 requirements
MCP SDK Tier Audit: modelcontextprotocol/csharp-sdk
Date: 2026-04-05
Branch: main
Auditor: mcp-sdk-tier-audit skill (automated + subagent evaluation)
Tier Assessment: Tier 1
All deterministic checks pass at Tier 1 thresholds, and the AI-assisted evaluation confirms comprehensive documentation (48/48 features with examples), a published dependency update policy, a published roadmap tracking spec implementation, and a detailed versioning/breaking-change policy.

Informational: Extension Spec Failures
Three client conformance scenarios targeting extension spec versions currently fail. These are not counted toward tier scoring (only date-versioned scenarios count) but are noted here as informational:
| Scenario |
Checks Failed |
Spec |
| auth/cross-app-access-complete-flow |
2/10 |
extension |
| auth/client-credentials-jwt |
2/10 |
extension |
| auth/client-credentials-basic |
2/10 |
extension |
If the extension scenarios are promoted to dated spec versions in a future release, these would become tier-relevant. Addressing them proactively is recommended.

Recommended Next Steps
- Monitor extension spec promotion — Track whether the three failing
extension auth scenarios get promoted to dated spec versions in upcoming MCP spec releases; address them before they become tier-relevant.
- Continue spec tracking cadence — The current 0-day gap between spec release and SDK release is excellent; maintain this responsiveness for future spec revisions.
- Maintain documentation quality — All 48 features have prose documentation with examples; continue updating docs when new features are added or existing ones evolve.
