Find elements on the page using multiple search criteria such as text, role, tag name, or attributes. Returns matching elements sorted by confidence.
AI agents call browser_find_elements to retrieve information from Fast Playwright MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool performs element discovery and inspection only. It queries the DOM to locate and return matching elements based on search criteria (text, role, tag name, attributes), analogous to a selector/search operation. No data is modified, deleted, or executed. The blast radius of misuse is minimal — an agent could query for sensitive information on a page, but cannot take actions or cause irreversible changes.
From the tool's definition Tool description states it 'Find elements on the page' and 'Returns matching elements' — this is a query operation with no side effects.
Documented attack patterns abuse exactly the kind of access browser_find_elements gives an agent:
PolicyLayer is an MCP gateway — it sits between your AI agents and Fast Playwright MCP, and nothing reaches the server without passing your rules. This is the rule we recommend for browser_find_elements:
{
"version": "1",
"default": "deny",
"tools": {
"browser_find_elements": {}
}
}browser_find_elements is read-only, so it stays allowed — but everything else on the server is denied unless you say otherwise.

Find elements on the page using multiple search criteria such as text, role, tag name, or attributes. Returns matching elements sorted by confidence. It is categorised as a Read tool in the Fast Playwright MCP MCP Server, which means it retrieves data without modifying state.
Register the Fast Playwright MCP server in PolicyLayer and add a rule for browser_find_elements: 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 Fast Playwright MCP. Nothing to install.
browser_find_elements 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 browser_find_elements 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 browser_find_elements. 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.
browser_find_elements is provided by the Fast Playwright MCP server (tontoko/fast-playwright-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
