Trigger a new deployment for your Rails application on Hatchbox. This tool initiates a deployment using Hatchbox
AI agents invoke triggerDeploy to trigger actions in Playwright Stealth. What it does depends on the arguments the agent supplies, and its effects often reach beyond the immediate call — builds kicked off, notifications sent, workflows started.
This tool executes a real-world deployment operation on a production or staging Rails application via Hatchbox. Deployments trigger code changes, restart services, and modify live infrastructure. While not destructive (deployments are typically reversible via rollback) or financial, the blast radius is high because a misconfigured or mistimed deployment can cause service outages, data issues, or rollback failures.
From the tool's definition Tool name 'triggerDeploy' and description 'Trigger a new deployment for your Rails application on Hatchbox.
Documented attack patterns abuse exactly the kind of access triggerDeploy gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Playwright Stealth, and nothing reaches the server without passing your rules. This is the rule we recommend for triggerDeploy:
{
"version": "1",
"default": "deny",
"tools": {
"triggerDeploy": {
"limits": [
{
"counter": "triggerdeploy_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}triggerDeploy stays usable, but rate-capped — a runaway agent can't fire it dozens of times a minute. Everything else on the server is denied unless you say otherwise.

Trigger a new deployment for your Rails application on Hatchbox. This tool initiates a deployment using Hatchbox. It is categorised as a Execute tool in the Playwright Stealth MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Playwright Stealth MCP server in PolicyLayer and add a rule for triggerDeploy: allow, deny, rate-limit, or require approval. Point your MCP client at the PolicyLayer proxy URL and the rule is enforced on every call, before it reaches Playwright Stealth. Nothing to install.
triggerDeploy is a Execute tool with high risk. Execute tools should be rate-limited and have argument validation enabled.
Yes. Add a rate_limit block to the triggerDeploy rule in your PolicyLayer policy. For example, setting max: 10 and window: 60 limits the tool to 10 calls per minute. Rate limits are tracked per agent session and reset automatically.
Set action: deny in the PolicyLayer policy for triggerDeploy. The AI agent will receive a policy violation error and cannot call the tool. You can also include a reason field to explain why the tool is blocked.
triggerDeploy is provided by the Playwright Stealth MCP server (pulsemcp/mcp-servers). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Playwright Stealth, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
Free to start. No card required.
