Query elements by CSS selector, return text/attributes of all matches.
AI agents call query_selector_all to retrieve information from MCP Camoufox without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and reads DOM element data (text and attributes) based on CSS selectors. It performs no modifications, deletions, or external operations. It is purely a query operation that returns information from the current page state. While the parent server is designed for web automation and bot evasion, this specific tool is a read-only operation with no side effects.
From the tool's definition Tool description: 'Query elements by CSS selector, return text/attributes of all matches.' The verb is 'query' and the action is to 'return' data without modification.

PolicyLayer is an MCP gateway — it sits between your AI agents and MCP Camoufox, and nothing reaches the server without passing your rules. This is the rule we recommend for query_selector_all:
{
"version": "1",
"default": "deny",
"tools": {
"query_selector_all": {}
}
}query_selector_all is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.
