Fly Managed Postgres

Field	Value
Cluster ID	ey5qn0yd84p08zmw
Name	moltnet-pg
Region	fra (Frankfurt)
Plan	Basic (shared CPU x2, 1GB RAM, 10GB disk)
Version	Postgres 17
Host	pgbouncer.ey5qn0yd84p08zmw.flympg.net
Dashboard	https://fly.io/dashboard/edouard-maleix/managed_postgres/ey5qn0yd84p08zmw

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

Configuration uses two files, both committed to git:

File	Contains	dotenvx-managed	Pre-commit validated
env.public	Non-secret config (domains, project IDs)	No	No
.env	Encrypted secrets only	Yes	Yes — dotenvx ext precommit

The .env.keys file holding the private decryption key is never committed.

Setup for new builders

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

For secrets in .env, get the DOTENV_PRIVATE_KEY from a team member:

echo 'DOTENV_PRIVATE_KEY="<key>"' > .env.keys

Or pass it inline:

DOTENV_PRIVATE_KEY="<key>" pnpm exec dotenvx run -f env.public -f .env -- <command>

Reading variables

# Non-secrets — always readable
cat env.public

# Secrets — requires private key
pnpm exec dotenvx get                    # all decrypted values from .env
pnpm exec dotenvx get OIDC_PAIRWISE_SALT # single value

Adding or updating a variable

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

# Secrets → use dotenvx (encrypts automatically)
pnpm exec dotenvx set KEY value

Never use dotenvx encrypt manually — it would flag env.public values. The pre-commit hook (dotenvx ext precommit) validates that .env has no unencrypted values. Files without a DOTENV_PUBLIC_KEY header (like env.public) are ignored by the hook.

Running commands with env loaded

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

dotenvx loads env.public as plain values and decrypts .env secrets, injecting both into the child process environment.

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

.env (encrypted, requires DOTENV_PRIVATE_KEY):

Variable	Purpose
OIDC_PAIRWISE_SALT	Ory OIDC pairwise salt

Computed at runtime (in deploy.mjs):

Variable	Source
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:

# Secrets → add to .env with: pnpm exec dotenvx set KEY value
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_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)
• dotenvx (used via npx @dotenvx/dotenvx)
• Access to .env.keys (contains DOTENV_PRIVATE_KEY for decrypting .env)
• 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_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) are in apps/mcp-server/fly.toml.

Note: The .env key names don't always match Fly.io secret names. ORY_PROJECT_API_KEY in .env 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.

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 -- node infra/ory/deploy.mjs

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

# Apply all (project config + branding + OPL)
npx @dotenvx/dotenvx run -f env.public -f .env -- 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 -- \
  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).
