AI agents call get_proctor_metadata to retrieve information from Playwright Stealth without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and lists metadata about available testing runtimes and exam configurations. It performs a query operation with no data modification, deletion, or execution of external operations. The use cases explicitly mention 'Discover' and 'Find,' which are read operations. This is a low-severity read operation suitable for lookup and discovery purposes.
From the tool's definition Tool description states it 'Get available runtimes and exams for Proctor testing' and 'Returns the list of available runtime environments...and exam types.' The verb 'Get' and 'Returns' indicate retrieval without modification. No side effects mentioned.
Documented attack patterns abuse exactly the kind of access get_proctor_metadata 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 get_proctor_metadata:
{
"version": "1",
"default": "deny",
"tools": {
"get_proctor_metadata": {}
}
}get_proctor_metadata is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get available runtimes and exams for Proctor testing. Returns the list of available runtime environments (Docker images) and exam types. Returns: - runtimes: Array of runtime configurations with id, name, and Docker image - exams: Array of exam types with id, name, and description Use cases: - Discover available runtime environments - Find the correct exam ID for a specific test type - Check which runtime versions are available. It is categorised as a Read tool in the Playwright Stealth MCP Server, which means it retrieves data without modifying state.
Register the Playwright Stealth MCP server in PolicyLayer and add a rule for get_proctor_metadata: 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.
get_proctor_metadata 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 get_proctor_metadata 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 get_proctor_metadata. 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.
get_proctor_metadata 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.
