What is create-trigger?

A tool for creating Harness triggers, which automatically start pipelines when events occur. It supports events such as Git changes, scheduled times, new container images, and Helm chart updates.

Use it to create webhook, cron-based, artifact, or manifest triggers in Harness. It generates the trigger YAML, creates the trigger through Harness, and verifies Git webhooks.

It removes the need to start certain builds by hand. You can define when a pipeline should run and add filters such as branches, payload data, schedules, or artifact paths.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Model	Per session	Once invoked
Fable 5.1	$0.00048	$0.01391
Opus 5.5	$0.00019	$0.00556
Sonnet 5.5	$0.00010	$0.00278
Haiku 4.5	$0.00005	$0.00139

Security

Grade A, and why

create-trigger scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 4d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

Create Trigger

Generate Harness Trigger YAML and push to Harness via MCP.

Instructions

Identify trigger type - Webhook (Git events), Scheduled (cron), Artifact (registry updates), or Manifest (Helm chart updates)
Configure conditions - Branch filters, payload conditions, cron expression, or artifact path
Generate YAML using the templates below, referencing the target pipeline
Create via MCP using harness_create with resource_type trigger
Verify webhook registration - For webhook triggers, confirm the webhook is registered in the Git provider

Trigger Types

Webhook - GitHub, GitLab, Bitbucket, Azure Repos, Custom
Scheduled - Cron-based scheduling
Artifact - Docker Hub, ECR, GCR, ACR, Nexus
Manifest - Helm chart updates
