Parameter Handling

If parameters are missing, use mcp_question to gather them:

mcp_question({
  questions: [
    {
      question: "What type of secret are you creating?",
      header: "Secret Type",
      options: [
        { label: "Infisical (Recommended)", description: "Store in centralized Infisical, generate .age via mkGenerator" },
        { label: "Legacy agenix file", description: "Direct .age encryption for binary files (certs, keys)" }
      ]
    }
  ]
})

For Infisical secrets, also ask:

mcp_question({
  questions: [
    {
      question: "Is this secret used by multiple different services?",
      header: "Secret Scope",
      options: [
        { label: "Yes - shared across services", description: "Same value used by openclaw, n8n, opencode, etc. → /shared/" },
        { label: "No - one service only", description: "Dedicated to a single service → /services/ or /hosts/" }
      ]
    }
  ]
})

// If service-specific, follow up:
mcp_question({
  questions: [
    {
      question: "Is this secret the same across all hosts running this service?",
      header: "Host Scope",
      options: [
        { label: "Yes - service-wide", description: "Same on any host running the service → /services/<service>/" },
        { label: "No - host-specific", description: "Different per host instance → /hosts/<host>/<service>/" }
      ]
    }
  ]
})

Then ask for the specific path components:

mcp_question({
  questions: [
    {
      question: "What is the service name?",
      header: "Service Name",
      options: [
        { label: "openclaw", description: "OpenClaw/Moltbot AI assistant" },
        { label: "opencode", description: "OpenCode AI coding services" },
        { label: "budgey", description: "Budgey finance assistant" },
        { label: "caddy", description: "Caddy reverse proxy" },
        { label: "n8n", description: "n8n workflow automation" }
      ]
    },
    {
      question: "What is the secret name?",
      header: "Secret Name",
      options: []  // Free text input
    },
    {
      question: "How should the value be set?",
      header: "Secret Value",
      options: [
        { label: "Generate random (64 hex chars)", description: "openssl rand -hex 32" },
        { label: "Generate random (32 hex chars)", description: "openssl rand -hex 16" },
        { label: "Enter value manually", description: "You will provide the value" }
      ]
    }
  ]
})

Infisical Workflow (Recommended)

Prerequisites

# Unlock agenix identity first (enter passphrase once per session)
just unlock

# Login to Infisical (interactive) if not already
infisical login --domain https://infisical.meskill.farm

# Or set token
export INFISICAL_TOKEN="your-token"

Step 1: Create Secret in Infisical

PROJECT_ID="f95d3144-22bb-4c95-9ee8-f3319d4924d5"

# Generate random value if needed
SECRET_VALUE=$(openssl rand -hex 32)

# Create the secret
infisical secrets set SECRET_NAME="$SECRET_VALUE" \
  --env=homelab \
  --path=/shared \
  --projectId=$PROJECT_ID

Step 2: Add Nix Configuration

Add to the appropriate host configuration:

# Enable Infisical integration (if not already)
ruinous.infisical.enable = true;

# Shared secret (used by multiple services)
age.secrets.<host>_<service>_<secret_name> = {
  generator.script = config.ruinous.infisical.mkGenerator {
    name = "GITHUB_TOKEN";
    path = "/shared";
  };
  mode = "400";
};

# Service-specific secret (not host-specific)
age.secrets.<host>_openclaw_openai_key = {
  generator.script = config.ruinous.infisical.mkGenerator {
    name = "OPENAI_API_KEY";
    path = "/services/openclaw";
  };
  mode = "400";
  owner = "jmeskill";
};

# Host-specific secret
age.secrets.chassis_openclaw_discord_token = {
  generator.script = config.ruinous.infisical.mkGenerator {
    name = "DISCORD_TOKEN";
    path = "/hosts/chassis/openclaw";
  };
  mode = "400";
  owner = "jmeskill";
};

Step 3: Generate and Rekey

# Generate secrets from Infisical
agenix generate -a

# Rekey for all hosts
just rekey

# Stage the generated files
git add secrets/

Step 4: Verify and Deploy

# Check build passes
just check <host>

# Deploy changes
just deploy <host>

# View the secret (after deployment)
# cat /run/agenix/<secret_name>

Decision Flow

Is this secret used by multiple different services?
├─ YES → /shared/
└─ NO → Is this secret the same across all hosts running this service?
         ├─ YES → /services/<service>/
         └─ NO → /hosts/<host>/<service>/

Path Reference

Path	Purpose	Examples
/shared/	Same value used by MULTIPLE services	GITHUB_TOKEN, ANTHROPIC_API_KEY, CLOUDFLARE_API_TOKEN
/services/<service>/	Service-specific, any host	/services/openclaw/OPENAI_API_KEY, /services/budgey/DATABASE_URL
/hosts/<host>/<service>/	Host-specific instance	/hosts/chassis/openclaw/DISCORD_TOKEN

When to Use Each

Use /shared/	Use /services/<service>/	Use /hosts/<host>/<service>/
Same API account for all	Isolated quota/billing per service	Different per host instance
GITHUB_TOKEN for all tools	Service needs own rate limits	Discord bot per host
Shared Cloudflare account	Rotate independently	Host-specific auth

Common Infisical Commands

PROJECT_ID="f95d3144-22bb-4c95-9ee8-f3319d4924d5"

# List secrets at path
infisical secrets --env=homelab --path=/shared --projectId=$PROJECT_ID

# Get single secret value
infisical secrets get SECRET_NAME --env=homelab --path=/shared \
  --projectId=$PROJECT_ID --plain

# Update existing secret
infisical secrets set SECRET_NAME="new-value" --env=homelab --path=/shared \
  --projectId=$PROJECT_ID

# Delete secret
infisical secrets delete SECRET_NAME --env=homelab --path=/shared \
  --projectId=$PROJECT_ID

# Create folder
infisical secrets folders create --name=newfolder --env=homelab --path=/ \
  --projectId=$PROJECT_ID

Secret References (Aliases)

Infisical supports references to avoid duplication:

# Create alias in same path
infisical secrets set 'GITHUB_ACCESS_TOKEN=${GITHUB_TOKEN}' \
  --env=homelab --path=/shared --projectId=$PROJECT_ID

# Reference /shared secret from a service path
infisical secrets set 'ANTHROPIC_API_KEY=${shared.ANTHROPIC_API_KEY}' \
  --env=homelab --path=/services/openclaw --projectId=$PROJECT_ID

# Reference /shared secret from a host-specific path
infisical secrets set 'GITHUB_TOKEN=${shared.GITHUB_TOKEN}' \
  --env=homelab --path=/hosts/chassis/openclaw --projectId=$PROJECT_ID

---

Legacy Agenix Workflow

Use for binary files (certificates, SSH keys) that can't be stored as text in Infisical.

Prerequisites

# Unlock agenix identity
just unlock

Creating a New Legacy Secret

1. Create directory structure:

   mkdir -p hosts/<hostname>/files/docker/env
   

2. Create plaintext content:

   cat > /tmp/secret.txt << 'EOF'
   SECRET_KEY=value
   API_TOKEN=value
   EOF
   

3. Encrypt the file:

   just encrypt <output-path>.age
   # Or with input file:
   agenix edit -i /tmp/secret.txt <output-path>.age
   

4. Clean up and rekey:

   rm /tmp/secret.txt
   just rekey
   

Legacy Nix Integration

age.secrets.<hostname>_<service>_<name> = {
  rekeyFile = ./files/docker/env/<service>.env.age;
  mode = "600";
};

Legacy File Locations

Purpose	Path Pattern
Docker env	hosts/<host>/files/docker/env/<service>.env.age
Caddyfiles	hosts/<host>/files/caddy/Caddyfile.age
Cloudflared certs	hosts/<host>/files/cloudflared/cert.pem.age
Cloudflared tunnels	hosts/<host>/files/cloudflared/<tunnel>.json.age

---

Decision Guide: Infisical vs Legacy

Use Infisical When	Use Legacy When
Text-based secrets (tokens, passwords, API keys)	Binary files (certificates, SSH keys)
Secrets shared across hosts	Host-specific file structures
Secrets that change frequently	Static credentials
Secrets you want to manage via UI	Secrets tightly coupled to file paths

---

Example: Creating a Webhook Secret

# 1. Unlock agenix identity
just unlock

# 2. Generate and store in Infisical
PROJECT_ID="f95d3144-22bb-4c95-9ee8-f3319d4924d5"
WEBHOOK_SECRET=$(openssl rand -hex 32)

infisical secrets set GITHUB_FORGE_WEBHOOK_SECRET="$WEBHOOK_SECRET" \
  --env=homelab --path=/shared --projectId=$PROJECT_ID

# 3. Add to Nix config (e.g., hosts/monolith/webhooks.nix)
# age.secrets.monolith_github_webhook_secret = {
#   generator.script = config.ruinous.infisical.mkGenerator {
#     name = "GITHUB_FORGE_WEBHOOK_SECRET";
#     path = "/shared";
#   };
#   mode = "400";
# };

# 4. Generate and rekey
agenix generate -a
just rekey
git add secrets/

# 5. Verify and deploy
just check monolith
just deploy monolith
