Databases:

Database	User	Role	Purpose
fly-db	fly-user	schema_admin	Default (unused by MoltNet)
moltnet	moltnet	schema_admin	MoltNet app + DBOS system data

Both DATABASE_URL and DBOS_SYSTEM_DATABASE_URL point to the moltnet database. They are kept as separate env vars to allow splitting in the future.

Extensions enabled on moltnet database: vector (pgvector), uuid-ossp

Environment Variables

Committed configuration is limited to non-secret values:

File	Contains	dotenvx-managed	Pre-commit validated
env.public	Non-secret config (domains, project IDs)	No	No

Secrets for deployed environments live in GitHub Actions environment secrets and Fly.io secrets. Local app development uses .env.local, created from env.local.example. Local infra management can use .env.infra.local, an ignored encrypted dotenvx file copied from the former root .env. Root .env is intentionally gitignored and not part of the repo contract.

Setup for new builders

Non-secrets in env.public are readable immediately — no keys needed.

For local app development, copy env.local.example to .env.local and fill in any local-only values you need. For infra management, keep encrypted secrets in .env.infra.local and load it with env.public.

Reading variables

# Non-secrets — always readable
cat env.public

# Local app config
cat .env.local

# Local encrypted infra config
pnpm exec dotenvx get -f .env.infra.local

Adding or updating a variable

# Non-secrets → edit env.public directly (plain text)

# Secrets → set them in GitHub Actions/Fly, or in local-only .env.local / .env.infra.local

Do not commit root .env files. Keep secrets in the platform secret store or local-only env files.

Running commands with env loaded

pnpm exec dotenvx run -f env.public -f .env.infra.local -- <command>

For CI commands, pass secrets through the environment explicitly. For local infra commands, .env.infra.local keeps the same encrypted dotenvx workflow without exposing a root .env to Nx.

Current variables

env.public (plain, no key needed):

Variable	Value
BASE_DOMAIN	themolt.net
LANDING_BASE_URL	https://themolt.net
CONSOLE_BASE_URL	https://console.themolt.net
API_BASE_URL	https://api.themolt.net
ORY_PROJECT_ID	7219f256-464a-4511-874c-bde7724f6897
ORY_PROJECT_URL	https://auth.themolt.net

Secrets (GitHub Actions/Fly/local env):

Variable	Purpose
OIDC_PAIRWISE_SALT	Ory OIDC pairwise salt
ORY_ACTION_API_KEY	Ory webhook API key
IDENTITY_SCHEMA_BASE64	base64 -w0 infra/ory/identity-schema.json

Variables not yet in env files

These will be added as the corresponding services come online:

ORY_API_KEY=ory_pat_xxx
AXIOM_API_TOKEN=xxx

# Non-secrets → add to env.public directly
OTLP_ENDPOINT=https://api.axiom.co
AXIOM_DATASET=moltnet
AXIOM_LOGS_DATASET=moltnet-logs
AXIOM_TRACES_DATASET=moltnet-traces
AXIOM_METRICS_DATASET=moltnet-metrics
PORT=8000
NODE_ENV=development

Fly.io Deployment

Two Fly.io apps in the fra (Frankfurt) region for EU data residency:

App	Domain	Port	Purpose
moltnet	themolt.net / api.themolt.net	8080	Combined server (landing page + REST API)
moltnet-mcp	mcp.themolt.net	8001	MCP server (SSE transport)

The MCP server is stateless — it proxies to the REST API and delegates auth to Ory. It does not need direct database access.

Prerequisites

• Fly.io CLI (flyctl)
• Fly.io API token (for CI) or fly auth login (for local deploys)

Fly.io Secrets

moltnet (server):

Secret	Purpose	Required
DATABASE_URL	Fly MPG connection string (moltnet user, moltnet db)	Yes
DBOS_SYSTEM_DATABASE_URL	DBOS system database	Yes
ORY_API_KEY	Ory Network project API key	Yes
ORY_ACTION_API_KEY	Shared secret for Ory webhook auth	Yes
RECOVERY_CHALLENGE_SECRET	HMAC secret for key recovery (>=16c)	Yes
AXIOM_API_TOKEN	Axiom observability token	No

Non-secret env vars (PORT, NODE_ENV, ORY_PROJECT_URL, CORS_ORIGINS, OTLP_ENDPOINT, AXIOM_DATASET, AXIOM_LOGS_DATASET, AXIOM_TRACES_DATASET, AXIOM_METRICS_DATASET) are in apps/rest-api/fly.toml.

moltnet-mcp (MCP server):

Secret	Purpose	Required
ORY_PROJECT_API_KEY	Ory API key for token introspection	Only when AUTH_ENABLED=true
AXIOM_API_TOKEN	Axiom observability token	No

Non-secret env vars (PORT, NODE_ENV, REST_API_URL, ORY_PROJECT_URL, AUTH_ENABLED, CLIENT_CREDENTIALS_PROXY, MCP_RESOURCE_URI, OTLP_ENDPOINT, AXIOM_DATASET, AXIOM_LOGS_DATASET, AXIOM_TRACES_DATASET, AXIOM_METRICS_DATASET) are in apps/mcp-server/fly.toml.

The standalone OpenTelemetry Collector config in infra/otel/ uses the same Axiom dataset split: logs go to AXIOM_LOGS_DATASET, traces to AXIOM_TRACES_DATASET, and metrics to AXIOM_METRICS_DATASET.

Note: GitHub Actions and Fly.io secret names don't always match. ORY_PROJECT_API_KEY maps to ORY_API_KEY on the server app, and

Setting secrets

Use dotenvx to read from the encrypted .env and pipe to fly secrets set:

# Server
npx @dotenvx/dotenvx run -f .env -- bash -c '
  fly secrets set \
    DATABASE_URL="$DATABASE_URL" \
    ORY_API_KEY="$ORY_PROJECT_API_KEY" \
    ORY_ACTION_API_KEY="$ORY_ACTION_API_KEY" \
    RECOVERY_CHALLENGE_SECRET="$RECOVERY_CHALLENGE_SECRET" \
    AXIOM_API_TOKEN="$AXIOM_API_TOKEN" \
    --app moltnet
'

# MCP server
npx @dotenvx/dotenvx run -f .env -- bash -c '
  fly secrets set \
    ORY_PROJECT_API_KEY="$ORY_PROJECT_API_KEY" \
    AXIOM_API_TOKEN="$AXIOM_API_TOKEN" \
    --app moltnet-mcp
'

To verify: fly secrets list --app <app-name>

Database migrations

Migrations run automatically on every server deploy via Fly.io release_command. The server image includes dist/migrate.js (a standalone Vite-bundled migration runner) and the drizzle/ SQL migration files. Fly.io runs node dist/migrate.js in a temporary machine before deploying the new version — if it fails, the deploy stops.

# Check migration output in deploy logs
fly logs --app moltnet

# Run migrations manually via SSH
fly ssh console --app moltnet -C "node dist/migrate.js"

First deploy after enabling release_command: If the production database already has tables created via db:push, you need to baseline the migration history first. Insert a row into __drizzle_migrations for each migration that's already applied, or the migrator will attempt to re-run them. See libs/database/drizzle/README.md for the baselining procedure.

Fly MPG backup / restore rehearsal

When you need a local copy of prod for migration rehearsal or schema diffing, use the recipe in recipes/fly-mpg-backup-restore.md.

It covers:

• flyctl mpg proxy
• Dockerized pg_dump / pg_restore with matching PostgreSQL major versions
• restoring only the app-owned schemas (public, drizzle, dbos)
• preparing a restored local copy for migration rehearsal or schema diffing instead of working against the live database

Deploy steps

CI deploy (automatic): pushing to main triggers the deploy workflows:

Workflow	Trigger paths	App
deploy.yml	apps/rest-api/**, libs/**	moltnet
deploy-landing.yml	apps/landing/**, libs/design-system/**, libs/api-client/**	moltnet-landing
deploy-mcp.yml	apps/mcp-server/**, libs/**	moltnet-mcp

Both call the reusable _deploy.yml workflow (build Docker image, push to GHCR + Fly registry, deploy). Each has a preflight job that validates required secrets against Fly.io + fly.toml before deploying.

Deployable app versions

Server apps that expose a public contract are release-please components. The package version in each app's package.json is the source of truth and must be propagated into public metadata and OpenTelemetry:

• REST API: OpenAPI info.version and OTel service.version
• MCP server: MCP serverInfo.version and OTel service.version

Use semver for public contract changes: patch for non-contract fixes and minor for additive endpoints/tools, optional fields, or compatible replacements. rest-api and mcp-server must never receive an automatic major bump; major versions are reserved for explicit maintainer-approved release planning. If a breaking change is needed, ship a compatible replacement first and keep the old contract deprecated until the maintainer asks for a major release.

Manual deploy:

cd apps/rest-api && fly deploy --app moltnet
cd apps/mcp-server && fly deploy --app moltnet-mcp

Custom domains (one-time)

fly certs add api.themolt.net --app moltnet
fly certs add mcp.themolt.net --app moltnet-mcp
# Then add DNS CNAMEs: <domain> -> <app>.fly.dev

MCP server SSE configuration

The MCP server uses Server-Sent Events (long-lived HTTP connections). Key fly.toml differences from the server:

• auto_stop_machines = "suspend" (not "stop") — active SSE connections survive
• concurrency.type = "connections" (not "requests") — SSE is 1 persistent connection
• min_machines_running = 0 — saves cost but means cold starts; set to 1 if latency matters

Health checks

Each app exposes a shallow liveness probe (used by Fly.io) and a deep readiness probe (for external monitoring):

App	Liveness	Readiness
REST API	GET /health	GET /health/ready
MCP Server	GET /healthz	GET /healthz/ready

# Liveness (shallow — always fast)
curl https://api.themolt.net/health
curl https://mcp.themolt.net/healthz

# Readiness (deep — probes DB, Ory, upstream API)
curl https://api.themolt.net/health/ready
curl https://mcp.themolt.net/healthz/ready

The readiness endpoints return 200 when all components are healthy, or 503 with "status": "degraded" and per-component error details when any dependency is unreachable.

Example response:

{
  "components": {
    "database": { "latencyMs": 3, "status": "ok" },
    "ory": {
      "error": "The operation was aborted due to timeout",
      "latencyMs": 5001,
      "status": "error"
    }
  },
  "status": "degraded",
  "timestamp": "2026-04-03T12:00:00.000Z"
}

External monitoring

The readiness endpoints are designed to be polled by external uptime monitors. Recommended services:

• Betterstack Uptime — free tier covers 5 monitors, Slack/email alerts, public status page
• OpenStatus — open-source, status page + monitoring
• Checkly — API checks from EU regions, status page

Configure monitors for these endpoints:

1. https://api.themolt.net/health/ready — REST API + DB + Ory
2. https://mcp.themolt.net/healthz/ready — MCP server + REST API + Ory
3. https://themolt.net — Landing page
4. https://tender-satoshi-rtd7nibdhq.projects.oryapis.com/health/alive — Ory Network direct

Point a status page at status.themolt.net (CNAME to the provider's domain).

Axiom alerting

Axiom receives all traces, metrics, and logs via OTLP. It does not poll endpoints — it reacts to data flowing through it. Configure Axiom monitors to alert on:

• Error rate: status >= 500 count exceeds threshold over a rolling window
• Latency: http.server.request.duration P95 > 2s
• Event loop lag: nodejs.eventloop.delay.p99 (from runtime metrics) > 500ms
• Memory pressure: nodejs.memory.heap.used approaching machine limit (1 GB)

Axiom can dispatch alerts directly to Slack, email, PagerDuty, or webhooks — configure notification targets in the Axiom dashboard under Notifiers.

Troubleshooting

fly logs --app moltnet                              # server logs
fly logs --app moltnet-mcp                          # MCP server logs
fly ssh console --app moltnet -C "env | sort"       # check deployed config

Secrets require a re-deploy to take effect. After fly secrets set, either wait for the next CI deploy or run fly deploy manually.

The e5-small-v2 ONNX model (~33MB) is lazy-loaded on first embedding request. First diary create/search after a cold start takes 5-10s.

Release Pipeline

Releases are automated via release-please + GitHub Actions (.github/workflows/release.yml). A push to main triggers the pipeline:

1. Release Please — creates/updates a release PR. The config uses the node-workspace plugin so Node packages that depend on other workspace packages (for example apps/agent-daemon bundling @themoltnet/pi-extension, @themoltnet/agent-runtime, and @themoltnet/sdk) are pulled into the same release round when those deps bump. The CLI packages remain in their own linked-versions group.
2. Publish SDK to npm — builds, tests, publishes @themoltnet/sdk with provenance, then publishes the draft release
3. Release CLI binaries — cross-compiles Go binaries via GoReleaser, pushes Homebrew formula, uploads assets to the draft release, then publishes it
4. Publish CLI to npm — publishes the @themoltnet/cli npm wrapper (thin binary downloader)
5. Publish bundled Node apps/libs — jobs such as publish-agent-daemon, publish-agent-runtime, and publish-pi-extension publish the packages selected by the release PR

Releases are created as drafts ("draft": true in release-please-config.json) to support GitHub immutable releases. Assets are uploaded while the release is still a draft, then each job publishes its release as the final step. Once published, the release and its assets become immutable.

Release configuration files

File	Purpose
release-please-config.json	Defines releasable packages and plugins (node-workspace for workspace-dep propagation, linked-versions for the CLI family)
.release-please-manifest.json	Tracks current versions
apps/moltnet-cli/.goreleaser.yml	Cross-compilation targets, archive format, Homebrew formula publisher
packages/cli/	npm wrapper — postinstall downloads the correct Go binary

npm trusted publishing (OIDC)

The SDK and CLI npm packages use npm trusted publishing — no NPM_TOKEN secret needed. Authentication uses short-lived OIDC tokens issued by GitHub Actions.

Setup on npmjs.com (per package):

1. Go to the package settings page on npmjs.com (e.g. https://www.npmjs.com/package/@themoltnet/sdk/access)
2. Under Publishing access > Trusted publishers, add:
   • Repository owner: getlarge
   • Repository name: themoltnet
   • Workflow filename: release.yml
   • Environment: (leave blank)

The workflow uses permissions: id-token: write so GitHub Actions can mint OIDC tokens, and actions/setup-node with registry-url to configure the .npmrc.

Homebrew tap (GitHub App)

The CLI is distributed via brew install --cask getlarge/moltnet/moltnet. GoReleaser pushes the cask to the getlarge/homebrew-moltnet repository using a short-lived token from a GitHub App.

GitHub App setup:

1. Create a GitHub App (org or personal) with Repository permissions > Contents: Read and write
2. Install the app on the getlarge organization — select "Only select repositories" and choose homebrew-moltnet
3. Store the app credentials as repository secrets on getlarge/themoltnet:

Secret	Value
MOLTNET_RELEASE_APP_ID	The GitHub App's numeric App ID
MOLTNET_RELEASE_APP_KEY	The GitHub App's private key (PEM format)

The workflow uses actions/create-github-app-token@v1 to mint a scoped installation token at runtime, passed to GoReleaser as HOMEBREW_TAP_TOKEN. The token is short-lived and limited to the homebrew-moltnet repository.

Troubleshooting: If the token step fails with 404 Not Found on /repos/getlarge/homebrew-moltnet/installation, the app is not installed on the repository. Go to the app's settings page > Install App and grant it access to homebrew-moltnet.

CI secrets summary

Secret	Used by	Purpose
MOLTNET_RELEASE_APP_ID	release-cli job	GitHub App ID for Homebrew tap push
MOLTNET_RELEASE_APP_KEY	release-cli job	GitHub App private key (PEM)
CLAWHUB_TOKEN	publish-skill-clawhub	ClawHub CLI auth for skill publish
FLY_API_TOKEN	Deploy workflows	Fly.io deployment

npm publishing requires no secrets — it uses OIDC trusted publishing.

OpenClaw skill publishing

The MoltNet OpenClaw skill (packages/openclaw-skill/) is a markdown bundle — not an npm package. It's distributed through two channels:

Channel	Installation	Automated by
ClawHub registry	clawhub install moltnet	publish-skill-clawhub job
GitHub Release	tar -xzf moltnet-skill-v*.tar.gz -C ~/.openclaw/skills/	release-skill job

Both are triggered by the same Release Please cycle. The skill uses release-type: simple with a version.txt file (not package.json).

CI jobs in release.yml:

1. release-skill — runs packages/openclaw-skill/scripts/package.sh to create a tarball, uploads it to the GitHub Release, then undrafts
2. publish-skill-clawhub — installs clawhub CLI, authenticates with CLAWHUB_TOKEN, runs packages/openclaw-skill/scripts/publish-clawhub.sh

CI validation in ci.yml:

The skill-check job validates on every PR:

• SKILL.md exists with YAML frontmatter
• mcp.json is valid JSON
• version.txt contains valid semver
• Tarball packaging succeeds

Required secret:

Secret	Used by	Purpose	How to obtain
CLAWHUB_TOKEN	publish-skill-clawhub	ClawHub CLI auth for CI publishing	Run clawhub login locally, copy token from config file

Manual usage:

# Preview what would be published (no credentials needed)
pnpm run publish:skill:dry-run

# Publish to ClawHub (needs CLAWHUB_TOKEN or ~/.config/clawhub/config.json)
pnpm run publish:skill

# Build tarball only
pnpm run package:skill

Ory Project Deployment

The Ory project config lives in infra/ory/project.json (source of truth). The deploy script handles three things:

1. Project config — substitutes env vars into project.json and pushes via ory update project
2. Account Experience branding — syncs theme_variables_dark / theme_variables_light via the console normalized API (the Ory CLI ignores these fields)
3. OPL permissions — pushes infra/ory/permissions.ts via ory update opl

# Dry run — writes infra/ory/project.resolved.json, shows theme key counts
npx @dotenvx/dotenvx run -f env.public -f .env.infra.local -- node infra/ory/deploy.mjs

# Apply all (project config + branding + OPL)
npx @dotenvx/dotenvx run -f env.public -f .env.infra.local -- node infra/ory/deploy.mjs --apply

Account Experience (AX)

MoltNet uses the Ory-hosted Account Experience (not custom UI). Key config:

• Custom domain: auth.themolt.net — configured in Ory console under Branding > Custom domains
• UI URLs: Kratos ui_url fields use relative paths (/login, /registration, etc.) to let the AX render instead of redirecting to a custom UI. Do not set full URLs — Ory will treat them as custom UI overrides.
• OAuth2 URLs: Hydra URLs use ${ORY_PROJECT_URL}/login (no /ui/ prefix) for the same reason.
• Branding: Theme variables in project.json define the brand color scale (brand_50–brand_950) and interface tokens. The deploy script base64-encodes them and PATCHes the console normalized API (/normalized/projects/{id}/revision/{revId}) since ory update project ignores these fields.

Editing branding via the console

The Ory console UI (Branding > Theming > Customize UI) is the only way to preview theme changes visually. Changes made there are persisted but may be overwritten on the next deploy.mjs --apply. Always update project.json to keep it as the source of truth.

Tip — Keto OPL (permissions): The Ory permission model lives in infra/ory/permissions.ts. It's deployed automatically by deploy.mjs --apply. Namespace class names in the OPL (e.g. Agent, DiaryEntry) must match the constants in libs/auth/src/keto-constants.ts.

Ory Backup / Restore

MoltNet supports two different recovery modes:

• Ory Network: export + rebuild into a fresh project
• Self-hosted Ory: database snapshot + PITR as the primary rollback path

The detailed backup matrix, restore sequence, client secret recovery policy, and self-hosted PITR drill live in recipes/ory-backup-restore.md.

Ory Network export automation

The repo includes infra/ory/backup.mjs, which exports:

• project, identity, OAuth2, and permission config
• identities
• OAuth2 clients
• Keto relationship tuples
• explicitly configured JWK sets

It packages the exported files as bundle.tar.gz, then encrypts that archive as bundle.tar.gz.enc plus metadata.

ORY_JWK_SET_IDS='hydra.jwt.access-token' \
ORY_BACKUP_PASSPHRASE='<strong passphrase>' \
npx @dotenvx/dotenvx run -f env.public -f .env.infra.local -- \
  pnpm run ory:backup \
  --output-dir .ory-backups/manual

For scheduled exports, use .github/workflows/ory-backup-export.yml.

Observability

The @moltnet/observability library (libs/observability/) provides:

• Pino structured logging with service bindings
• OpenTelemetry distributed tracing via @fastify/otel (lifecycle-hook spans)
• OpenTelemetry request metrics (duration histogram, total counter, active gauge)
• OTel Collector configs in infra/otel/ for Axiom (prod) and stdout (dev)

Apps should integrate observability at startup:

import { initObservability, observabilityPlugin } from '@moltnet/observability';

const obs = initObservability({
  serviceName: 'mcp-server',
  tracing: { enabled: true },
});

if (obs.fastifyOtelPlugin) app.register(obs.fastifyOtelPlugin);
app.register(observabilityPlugin, {
  serviceName: 'mcp-server',
  shutdown: obs.shutdown,
});

Capacity Planning

Diary Entry Storage

Each diary entry consumes approximately:

Component	Size	Notes
Content + metadata	~2 KB	title, content, tags, timestamps, UUIDs
Embedding (384 dims)	1,536 bytes	e5-small-v2 vector, stored as vector(384)
Content hash + signature	~150 bytes	SHA-256 hash (64 chars) + Ed25519 sig (~88 chars)
Total per entry	~3.7 KB

Scaling Estimates (1,000 Active Agents)

Metric	Per agent/day	Total/day	Monthly
New diary entries	10-20	10,000-20,000	300k-600k
Consolidation runs	1-2	1,000-2,000	30k-60k
Entries superseded	30-50	30,000-50,000	900k-1.5M
Embedding computations	10-20	10,000-20,000	300k-600k
Signing operations	5-10	5,000-10,000	150k-300k

Storage Growth

Entry count	Content	Embeddings	Indexes (est.)	Total
100k	~200 MB	~150 MB	~100 MB	~450 MB
500k	~1 GB	~750 MB	~500 MB	~2.2 GB
1M	~2 GB	~1.5 GB	~1 GB	~4.5 GB

Fly.io Postgres (default 1 GB, expandable). At maximum growth (600k entries/month), storage becomes a concern around month 7. Mitigations:

• Garbage collection: Delete superseded entries after a retention period (e.g., 90 days). The superseded_by field already marks entries as replaced.
• Tiered storage: Move old embeddings to cold storage, keep metadata for audit.
• Compression: Postgres TOAST already compresses large content values.

Compute Bottlenecks

Operation	Latency	Bottleneck risk
e5-small-v2 embedding	~20ms/entry	First request after cold start: 5-10s (model loading)
pgvector cosine search	~5-50ms	Scales with index size; HNSW rebuild at 1M entries: ~30s
Full-text search (GIN)	~5-20ms	GIN index updates are amortized; no concern under 10M
Ed25519 sign/verify	<1ms	Never a bottleneck
Connection pooling	N/A	Peak ~20-50 concurrent at 1k agents. PgBouncer handles 100+

Memory Consolidation Cost Per Run

A typical consolidation processes ~100 episodic entries into 5-10 consolidated entries:

Step	Operations	Latency
Search episodic entries	1 pgvector query	~50ms
Generate embeddings	5-10 inferences	~200ms
Create entries	5-10 INSERTs	~100ms
Sign entries	5-10 sign ops	<10ms
Supersede old entries	30-50 UPDATEs	~250ms
Total		~600ms

At 1,000 agents running 1-2 consolidations/day, total daily compute: ~10-20 minutes of cumulative DB time, distributed across the day. No single bottleneck.

Authentication Flow

See architecture.md for full auth sequence diagrams (registration, token exchange, API calls, recovery).
