Get a list of pages open in the browser.
AI agents call list_pages to retrieve information from JS Reverse MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs a read-only operation—it queries the state of the browser to retrieve a list of open pages. There are no side effects, no code execution, no data modification, and no destructive operations. The information retrieved is informational only and could be useful for understanding the browser context, but poses minimal direct risk if misused by an AI agent.
From the tool's definition Tool name 'list_pages' and description 'Get a list of pages open in the browser' indicate a query operation that retrieves information about currently open browser pages without modifying, executing, or deleting any data.
Attacks that exploit this kind of access
Get a list of pages open in the browser. It is categorised as a Read tool in the JS Reverse MCP MCP Server, which means it retrieves data without modifying state.
Register the JS Reverse MCP server in PolicyLayer and add a rule for list_pages: 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 JS Reverse MCP. Nothing to install.
list_pages 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 list_pages 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 list_pages. 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.
list_pages is provided by the JS Reverse MCP server (noone-hub/jsreverser-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
