AI agents call query_page to retrieve information from Wasp 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 data from webpages without creating, modifying, deleting, or executing any operations. It is a read-only operation that extracts information based on user questions. The low severity reflects minimal risk—the worst outcome is returning irrelevant or incorrect information from a webpage.
From the tool's definition Tool description states it lets Claude 'query arbitrary webpages' and 'fetch only relevant sections' in response to natural-language questions.
Attacks that exploit this kind of access
Ask a natural-language question about a webpage. It is categorised as a Read tool in the Wasp MCP Server, which means it retrieves data without modifying state.
Register the Wasp MCP server in PolicyLayer and add a rule for query_page: 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 Wasp. Nothing to install.
query_page 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 query_page 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 query_page. 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.
query_page is provided by the Wasp MCP server (sfeeney1897/wasp-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
