AGT First Host is the entry point for agents connecting to the AGT automation framework. It initializes secure sessions, validates credentials, and routes requests to the appropriate execution layer.
Designed for production workloads, this component balances low latency with strict access controls. The following sections detail its architecture, configuration, and operations.
| Component | Role | Protocol | Default Port |
|---|---|---|---|
| AGT First Host | Session initiation and policy enforcement | gRPC over TLS | 8443 |
| Agent Loader | Activates registered agent profiles | HTTP/2 | 8080 |
| Policy Engine | Evaluates permissions and routing | REST | 9090 |
| Audit Collector | Records events for compliance | Syslog | 514 |
Host Security Model
AGT First Host enforces a zero-trust security model for every inbound connection. It combines mutual TLS, short-lived tokens, and scoped policies to minimize lateral movement.
Each session receives a unique identifier tied to identity, device posture, and network context. This enables fine-grained observability and rapid incident response.
Configuration Management
Administrators define host behavior through declarative YAML files. Sections cover listeners, allowed origins, and retry budgets for backend dependencies.
Dynamic reloading ensures updates take effect without dropping active connections. Validation hooks prevent misconfigurations before they reach production.
Operational Monitoring
Built-in metrics expose request rates, error ratios, and latency distributions. Exporters send data to Prometheus, Datadog, and similar platforms.
Health check endpoints respond only when the component is ready to serve traffic. Integration with Kubernetes probes supports automated recovery workflows.
Troubleshooting Paths
When sessions fail, operators can inspect structured logs with correlation IDs. Step-by-step diagnostics isolate issues in certificate validation, policy evaluation, or backend connectivity.
Support packages bundle configuration snapshots and recent events for faster triage. Escalation guides help teams reproduce and resolve complex incidents.
Getting Started with AGT First Host
- Install the host binary and place the initial configuration in /etc/agt/hosts.yaml.
- Generate mTLS certificates using the provided tooling and register the host with the policy engine.
- Define agent profiles and route maps before enabling production traffic.
- Enable metrics and configure log shipping to your monitoring stack.
- Run automated integration tests to verify connectivity and policy enforcement.
FAQ
Reader questions
How does AGT First Host validate agent credentials?
It verifies mTLS certificates against a trusted CA and checks scoped JWT tokens for permissions and expiry before establishing a session.
Can I run multiple AGT First Host instances behind a load balancer?
Yes, you can deploy redundant hosts behind a load balancer as long as they share synchronized policy stores and certificate configurations.
What happens during a configuration reload?
The host validates the new configuration, applies it in memory, and gracefully migrates existing connections without dropping traffic.
How are audit logs structured and where are they shipped?
Events are emitted as structured JSON with correlation IDs and sent to Syslog, where they can be forwarded to SIEM platforms for analysis.
