What happened
Nous Research shipped Hermes Agent v0.20.2 (Aug 16, 2026), an open-source agent-runtime patch adding MCP health checks/deep links, profile-scoped authentication resolution, and hardening to chat and cron execution surfaces.
Why it matters
Addresses concrete operational-security gaps (credential scope drift, unmonitored scheduled agent actions, unhealthy MCP endpoints) that are common root causes in recent agent-hijacking incidents.
Applicability
Teams running Hermes Agent or similar open-source agent runtimes should validate MCP allowlists and credential scoping against this release before upgrading production deployments.
