Get the full DOM of the current page. (Deprecated, use get-context instead)
AI agents call get-full-dom to retrieve information from Playwright MCP without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves the Document Object Model (DOM) of a webpage, which is a read-only query operation. It has no side effects, does not execute code, modify data, delete content, or trigger external operations. The low severity reflects minimal risk even if misused by an AI agent, as DOM retrieval cannot cause damage.
From the tool's definition Tool name is 'get-full-dom' and description states 'Get the full DOM of the current page.' The verb 'Get' and the read-only nature of DOM access indicates retrieval of page structure without modification.

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

Get the full DOM of the current page. (Deprecated, use get-context instead). It is categorised as a Read tool in the Playwright MCP MCP Server, which means it retrieves data without modifying state.
Register the Playwright MCP server in PolicyLayer and add a rule for get-full-dom: 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 Playwright MCP. Nothing to install.
get-full-dom 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-full-dom 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-full-dom. 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-full-dom is provided by the Playwright MCP server (qabyai/playwright-mcp). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
