Get the full DOM structure or specific element data (see browser_docs)
AI agents call browser_get_dom to retrieve information from Browser MCP Server without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool queries and retrieves DOM structure information from the browser, which is a read-only operation with no side effects. It does not execute code, modify the DOM, delete data, or trigger financial transactions. The action is purely informational retrieval.
From the tool's definition Tool name 'browser_get_dom' and description 'Get the full DOM structure or specific element data' indicate retrieval of DOM data without modification or execution.

Register the Browser MCP Server MCP server in PolicyLayer and add a rule for browser_get_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 Browser MCP Server. Nothing to install.
browser_get_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 browser_get_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 browser_get_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.
browser_get_dom is provided by the Browser MCP Server MCP server (madebytokens/browser-mcp-server). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
