Runs Playwright tests with JSON reporter and returns structured results with pass/fail status, duration, and error messages.
AI agents invoke playwright to trigger actions in Make. 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.
Playwright tests execute arbitrary browser actions and scripts. While framed as 'tests', they can perform real side effects such as form submissions, API calls, and file operations. This fits the Execute category with high severity due to the broad blast radius of automated browser execution.
From the tool's definition 'Runs Playwright tests' — executes browser automation/test scripts whose effects depend on what the tests do (network requests, UI interactions, file I/O, etc.)
Documented attack patterns abuse exactly the kind of access playwright gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Make, and nothing reaches the server without passing your rules. This is the rule we recommend for playwright:
{
"version": "1",
"default": "deny",
"tools": {
"playwright": {
"limits": [
{
"counter": "playwright_rate",
"window": "minute",
"max": 10,
"scope": "grant"
}
]
}
}
}playwright 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.

Runs Playwright tests with JSON reporter and returns structured results with pass/fail status, duration, and error messages. It is categorised as a Execute tool in the Make MCP Server, which means it can trigger actions or run processes. Use rate limits and argument validation.
Register the Make MCP server in PolicyLayer and add a rule for playwright: 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 Make. Nothing to install.
playwright 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 playwright 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 playwright. 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.
playwright is provided by the Make MCP server (Dave-London/Pare). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Make, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
