SentryAgent.ai AgentIdP — DevOps Documentation
Operational reference for engineers who deploy, configure, and maintain the AgentIdP infrastructure.
System Overview
SentryAgent.ai AgentIdP is a Node.js REST API backed by PostgreSQL and Redis. It runs as a single stateless application process. All state lives in PostgreSQL (durable) and Redis (ephemeral cache and rate limiting).
Stack:
- Runtime: Node.js 18+ (TypeScript, compiled to JS)
- Application: Express 4.18 on port 3000
- Database: PostgreSQL 14+ (primary data store)
- Cache: Redis 7+ (token revocation, rate limiting, monthly token counters)
