April 2026 performance highlights: Delivered foundational DataStorage API and session-management migration in stacklok/toolhive, enabling metadata-only storage and pluggable backends with cross-pod session restoration. Implemented two storage backends (LocalSessionDataStorage and RedisSessionDataStorage) and renamed write semantics from Store/StoreIfAbsent to Upsert/Create, plus RestoreSession scaffolding and hijack-prevention restore paths. Strengthened MCP routing and health-check robustness by routing MCP sessions to the originating backend pod using httptrace and enabling automatic reinitialization on pod replacements, reducing session-not-found errors. Hardened Redis-backed session metadata lifecycle with RemoveBackendFromMetadata and NotifyBackendExpired, and removed unnecessary storage.Load calls to keep Redis metadata in sync with live backends. Improved performance and concurrency through ValidatingCache enhancements, including LRU capacity, updated storage.Update semantics, and expanded singleflight boundary to reduce storage pressure under concurrent restores. Extended cross-domain work across VMCP/LLM: CLI scaffolding and tests, TLS skip-verify flag support, and enhanced E2E test infra; documented Redis horizontal-scaling scenarios and VMCP architecture for improved operator guidance.

March 2026 performance highlights for stacklok/toolhive focused on security, scalability, and reliability. Key feature deliveries include the rollout of Session Management V2 as the default pathway (removing legacy V1) with a two-phase VMCP session manager bridging to the MCP SDK, and the removal of the V2 flag in favor of a single session flow. HMAC-SHA256 token binding was introduced and moved to session-level validation, with automated management of HMAC secrets and end-to-end tests validating token binding behavior. Redis-backed session storage was implemented, including RedisConfig and RedisStorage, a NewManagerWithRedis constructor, and RunConfig integration to enable horizontal scaling. CRD changes were introduced to support horizontal scaling (SessionStorageConfig, Replicas, BackendReplicas) and the propagation of per-backend session metadata through transport flows. SIGTERM-aware graceful shutdown for the proxyrunner and session-aware routing improvements in proxy transports were implemented, along with the ability to attach backend_url metadata to routed sessions. Health checks were hardened: outgoing credentials are injected during health probes, /status reports reflect live health monitor state, and SSE connections are exempt from WriteTimeout. CI reliability improvements were made by adjusting the build cache workflow. Overall, the month delivered robust security, scalable session state, and improved operational resilience across the MCP surface, enabling safer rollout of features and faster incident identification and recovery.
