# Oikos

Agentic homelab operating system written in Go. Single binary (`cmd/oikos`),
Docker-deployed on mac-mini, with a standalone Nomos MCP agent gateway
(`cmd/nomos`). Manages the **hubris** Proxmox homelab autonomously — observes
state, classifies actions against policy, executes approved procedures over SSH,
learns from outcomes, and escalates when uncertain.

**For agents running on enrolled clients:** start with [AGENTS.md](AGENTS.md).
**For client machines:** see [CLIENTS.md](CLIENTS.md).
**For developers:** see [CONTRIBUTING.md](CONTRIBUTING.md).

## Quick start

```bash
# Dev stack (postgres + api + scheduler). The api/nomos
# services need a shared token — every route requires a real bearer
# credential, there's no dev-open bypass.
OIKOS_MCP_BEARER_TOKEN=dev-token docker compose --profile dev up -d

# Full stack (adds Nomos agent gateway)
OIKOS_MCP_BEARER_TOKEN=dev-token docker compose --profile full up -d

# Build standalone binary
go build -o bin/oikos -tags timetzdata ./cmd/oikos

# Run all roles in one process (dev mode)
OIKOS_DATABASE_URL="postgres://oikos:oikos_dev@localhost:5432/oikos?sslmode=disable" \
  OIKOS_API_TOKEN=dev-token \
  go run ./cmd/oikos all

# Control-room SPA + desktop app: own repo — dtoro/oikos-web
# (~/Projects/oikos-web; cd web && OIKOS_API_TOKEN=dev-token npm run dev)
```

| Component | Port | Role |
|-----------|------|------|
| `oikos api` | 8090 | REST API + MCP server (tool list in [AGENTS.md §3](AGENTS.md#3-the-mcp-server)) |
| `oikos scheduler` | — | Probe runner, signal lifecycle, metrics |
| `nomos serve` | 8092 | MCP client gateway, query routing |

## Phases

| Phase | Status | Description |
|-------|--------|-------------|
| 1 — Ontology + DB | ✅ | TimescaleDB, migrations, seeds, blast_radius |
| 2 — API | ✅ | OpenAPI-first REST + MCP, auth, SSE, audit |
| 3 — Control loop | ✅ | Scheduler, actuator, learning, classifier |
| 4 — Nomos agent | ✅ | Standalone MCP client gateway, agent activity |
| 5 — Secrets | ✅ | Infisical backend + SOPS fallback, rotation runbooks |
| 6 — Deploy | ✅ | CI pipeline, cutover checklist, watchdog, rollback |

## Operations

### API endpoints

```bash
curl -H "Authorization: Bearer $OIKOS_API_TOKEN" \
  http://localhost:8090/api/v1/entities?type=service  # fleet
curl -H "Authorization: Bearer $OIKOS_API_TOKEN" \
  http://localhost:8090/api/v1/health                  # fleet health
curl -H "Authorization: Bearer $OIKOS_API_TOKEN" \
  http://localhost:8090/api/v1/agent-activity          # agent log
```

### Nomos queries

```bash
# Structured tool call
curl -X POST localhost:8092/query -H "Content-Type: application/json" \
  -d '{"tool":"get_blast_radius","args":{"entity_id":"service:authentik"}}'

# Natural language
curl -X POST localhost:8092/query -H "Content-Type: application/json" \
  -d '{"query":"what depends on authentik?"}'
```

### CLI

```bash
oikos migrate     # apply DB migrations
oikos seed        # ingest ontology/inventory/policy seeds
oikos export      # export DB state to YAML
oikos api         # serve REST + MCP
oikos scheduler   # run observe loop
oikos all         # all roles in one process
oikos secret list # enumerate SOPS secrets
oikos secret migrate  # SOPS → Infisical
```

### Web UI

The control-room SPA and the Wails desktop wrapper live in their own repo,
[dtoro/oikos-web](https://git.hubris.network/dtoro/oikos-web) (local
checkout `~/Projects/oikos-web`) — extracted in Phase 1 of
[plans/2026-08-15-hexagonal-architecture.md](plans/2026-08-15-hexagonal-architecture.md).
The SPA talks to `api`/`nomos` over HTTP with a bearer token entered on
first launch. It deploys as its own compose project publishing `8091:80`;
the outer Caddy (LXC 121) targets that published port, so serving and auth
are unchanged from the pre-split stack.

```

## For agents

See [AGENTS.md](AGENTS.md) for the full orientation. Quick reference:

- **Source of truth:** DB (runtime) then seeds (bootstrap). Old wiki is
  archived at `archive/knowledge/` — use MCP `search_knowledge` instead.
- **Mutations:** classify against policy, request approval for
  `destructive`/`config_mutation`
- **Secrets:** Infisical (primary) or SOPS (fallback) — never hardcode
