AI agents call get_html to retrieve information from WebControl without modifying anything — typically the context-gathering step in research, monitoring, and reporting workflows, before the agent takes action elsewhere.
This tool retrieves and returns data (HTML content) from the browser's current page state without creating, modifying, deleting, or executing code. It is a passive information-gathering operation with no side effects. The truncation mentioned suggests the output is bounded. Risk is low as misuse would only expose page content the agent already navigated to.
From the tool's definition Tool name 'get_html' and description 'Get the full rendered HTML of the current page' indicate a read-only retrieval operation with no modification or execution of external effects.

Register the WebControl MCP server in PolicyLayer and add a rule for get_html: 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 WebControl. Nothing to install.
get_html 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_html 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_html. 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_html is provided by the WebControl MCP server (matansht/webcontrol). PolicyLayer sits as a proxy in front of this server to enforce policies before tool calls reach the server.
