Read the test source file. With resolve=true, returns only the test body plus referenced page object method bodies \u2014 saves tokens vs reading full files.
AI agents call e2e_get_test_source to retrieve information from Playwright Autopilot without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and queries test source code for inspection. It has no side effects—it does not execute tests, modify code, or trigger external operations. The resolve parameter is a read-only optimization that filters which parts of the source are returned. This is a passive retrieval operation, fitting the Read category.
From the tool's definition Tool name contains 'get' and description explicitly states 'Read the test source file'; returns test code without modification.
Documented attack patterns abuse exactly the kind of access e2e_get_test_source gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Playwright Autopilot, and nothing reaches the server without passing your rules. This is the rule we recommend for e2e_get_test_source:
{
"version": "1",
"default": "deny",
"tools": {
"e2e_get_test_source": {}
}
}e2e_get_test_source is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Read the test source file. With resolve=true, returns only the test body plus referenced page object method bodies \u2014 saves tokens vs reading full files. It is categorised as a Read tool in the Playwright Autopilot MCP Server, which means it retrieves data without modifying state.
Register the Playwright Autopilot MCP server in PolicyLayer and add a rule for e2e_get_test_source: 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 Autopilot. Nothing to install.
e2e_get_test_source is a Read tool with low risk. Read-only tools are generally safe to allow by default.
Yes. Add a rate_limit block to the e2e_get_test_source 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 e2e_get_test_source. 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.
e2e_get_test_source is provided by the Playwright Autopilot MCP server (kaizen-yutani/playwright-autopilot). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
Start from Playwright Autopilot, add the rest of your stack, and see everything your agents can call. Then put policy on all of it.
