List all open browser tabs/pages
AI agents call list_pages to retrieve information from BrowserPilot MCP 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 the current state of open browser tabs without modifying, executing, or deleting anything. It is analogous to a 'list' or 'get' operation. Even in a browser automation context, listing open pages carries minimal risk: an agent misusing this tool could only gather information about what tabs exist, not interact with them or cause harm.
From the tool's definition Tool name is 'list_pages' and description states 'List all open browser tabs/pages' — a pure information retrieval action with no side effects or state modifications.
Attacks that exploit this kind of access
List all open browser tabs/pages. It is categorised as a Read tool in the BrowserPilot MCP MCP Server, which means it retrieves data without modifying state.
Register the BrowserPilot 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 BrowserPilot 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 BrowserPilot MCP server (sept-7-qi/browserpilot-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
