AI agents call get_page_state to retrieve information from PageMap without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries current page metadata (URL and title) and performs no modifications, executions, or destructive actions. It is analogous to a safe getter that returns read-only state information. The low severity reflects minimal blast radius: retrieving page metadata poses no meaningful risk to the system or data integrity.
From the tool's definition Tool description states it retrieves 'lightweight current page state (URL, title)' — a query operation with no side effects. The verb 'get' and the retrieval-only nature confirm this is a Read operation.
Attacks that exploit this kind of access
Get lightweight current page state (URL, title) without full Page Map rebuild. It is categorised as a Read tool in the PageMap MCP Server, which means it retrieves data without modifying state.
Register the PageMap MCP server in PolicyLayer and add a rule for get_page_state: 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 PageMap. Nothing to install.
get_page_state 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_page_state 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_page_state. 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_page_state is provided by the PageMap MCP server (oci:docker.io/retio1001/pagemap:0.7.3). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
