AI agents call getPageUrl to retrieve information from PlayMCP Browser Automation Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves information about the current browser state (the page URL) without modifying, executing code, deleting data, or triggering external operations. It is purely informational and read-only.
From the tool's definition Tool name is 'getPageUrl' and description states it 'Get[s] the URL of the current page' — a retrieval operation with no side effects.
Documented attack patterns abuse exactly the kind of access getPageUrl gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and PlayMCP Browser Automation Server, and nothing reaches the server without passing your rules. This is the rule we recommend for getPageUrl:
{
"version": "1",
"default": "deny",
"tools": {
"getPageUrl": {}
}
}getPageUrl is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Get the URL of the current page. It is categorised as a Read tool in the PlayMCP Browser Automation Server MCP Server, which means it retrieves data without modifying state.
Register the PlayMCP Browser Automation Server MCP server in PolicyLayer and add a rule for getPageUrl: 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 PlayMCP Browser Automation Server. Nothing to install.
getPageUrl 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 getPageUrl 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 getPageUrl. 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.
getPageUrl is provided by the PlayMCP Browser Automation Server MCP server (jomon003/playmcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
