Deploy Workflow

Push a local .workflow.ts to n8n via n8nac, verify remote state, run a live test.

Why disable-model-invocation: true? Deploy mutates remote state (push, optional activate, optional production test). Plugin policy: side-effecting skills must be explicitly invoked by the user, never auto-triggered by the model. Skills like /n8n-autopilot:build-workflow may auto-trigger because they include user-confirmation gates at the deploy step. Apply the same flag to any future skill that performs an irreversible remote mutation without an explicit user gate.

Steps

1. Resolve workflow

• File path (e.g., workflows/create-lead.workflow.ts) — use directly
• Workflow name (e.g., create lead) — find matching .workflow.ts in workflows/

If $ARGUMENTS is provided, use it. Otherwise, ask the user.

2. Validate before push (mandatory)

npx n8nac skills validate workflows/<name>.workflow.ts --strict --json

If validation fails → stop and report. Do not push with validation errors. For interpreting the error (false-positives, expression vs schema errors, auto-sanitization, bulk fixes), consult the n8n-validation-expert guidance skill — n8nac's raw validator messages are often terse.

3. Drift check (mandatory — enforced by push-gate hook)

# Extract workflow id from @workflow({ id: '...' }) in the file
WF_ID=$(grep -oE "id:[[:space:]]*['\"][A-Za-z0-9]{10,}['\"]" workflows/<name>.workflow.ts | head -1 | grep -oE "[A-Za-z0-9]{10,}")

# Refresh remote cache, then read sync status
npx n8nac fetch "$WF_ID"
npx n8nac list --search "$WF_ID" --json

Decision table:

If the user has confirmed they want to discard the remote change:

N8N_AUTOPILOT_ALLOW_LOCAL_WINS=1 npx n8nac push workflows/<name>.workflow.ts --verify

4. Push + verify in one call

mcpTrigger check: If the workflow contains mcpTrigger, the PreToolUse hook (ensure-mcp-trigger-setting.sh) auto-fixes availableInMCP: false → true on push and warns when the field is missing entirely — see the warning and patch the source file if needed.

@workflow description field (n8nac 1.7.0+): Set description for better discoverability in n8nac list + n8n UI:

@workflow({ name: "My Workflow", description: "What it does in one sentence", settings: { ... } })

npx n8nac push workflows/<name>.workflow.ts --verify

--verify fetches the workflow after push and validates it against the local schema in one call. If verify fails → re-push.

5. Check credential presence

npx n8nac workflow credential-required <workflowId>

• Exit 0: all present → proceed to test
• Exit 1: credentials missing → report which credentials are needed, skip live test

6. Trigger classification + payload inference

npx n8nac test-plan <workflowId> --json

Extract triggerType, testable, suggestedPayload.

7. Live test (test URL — no activation needed)

n8nac test calls the test URL (/webhook-test/) by default.

npx n8nac test <workflowId> --data '<suggestedPayload from step 6>'
# For GET/HEAD webhooks (workflow reads $json.query):
npx n8nac test <workflowId> --query '<suggestedPayload>'

• Class A error (exit 0): missing credentials / model → report to user, do not iterate.
• Class B error (exit 1): wiring error → fix → re-validate → re-push (--verify) → re-test (max 3 cycles).

8. Production test (optional, only with --activate)

If the user passes --activate:

1. Activate the workflow:

   npx n8nac workflow activate <workflowId>
   

2. Production test:

   npx n8nac test <workflowId> --prod --data '<payload>'
   

3. On success → workflow stays active.
4. On failure → deactivate via npx n8nac workflow deactivate <workflowId>, report error.

9. mcpTrigger publish notice (manual)

After a successful push, check whether the workflow uses mcpTrigger:

grep -l "mcpTrigger\|n8n-nodes-langchain.mcpTrigger" workflows/<name>.workflow.ts

If yes, resolve the user-facing URL via the CLI (do not string-concat <host>/workflow/<id>):

npx n8nac workflow present <workflowId> --json

Surface a prominent notice using that URL:

⚠️  MANUAL PUBLISH REQUIRED — mcpTrigger detected

The MCP endpoint will return 404 until the workflow is published.

Open n8n UI:  <url from `n8nac workflow present`>
Click:        "Publish" button

n8nac push writes a new draft. The previously-published version stays live, but its MCP endpoint may diverge from the new draft. Each push to an mcpTrigger workflow requires a fresh UI publish — n8nac cannot publish on your behalf.

Safety

• Always validate before pushing.
• Workflows deploy as inactive by default. n8nac test uses the test URL, no activation needed.
• --activate + --prod tests against the production webhook URL — use with caution.
• disable-model-invocation: true — deployment has side effects.
